Fall Protection Strategies For DMI Standing Seam Roofs

See the Roof Anchor Compatibility Chart for Dimensional Metals Standing Seam Panels.

Who Is Dimensional Metals, Inc. (DMI)?

Dimensional Metals, Inc. began in 1988 when Phil and Steve Gastaldo needed better metal panels than what the market offered.

Instead of settling, they purchased their first rollformer in the mid-1980s and manufactured panels for their own projects. The results exceeded their expectations, and the demand for higher-quality panels pushed them to launch DMI as a standalone company.

Growth accelerated when the Wissman family invested in the company in 1996. Steve Wissman stepped in as CEO in 1998 and moved to Columbus to guide operations. The company now works from its headquarters in Reynoldsburg, Ohio.

What Is the Most Compatible Fall Protection Equipment for Dimensional Metals, Inc. (DMI)?

Safe work on DMI standing seam systems starts with anchors that match the seam shape and protect the weather-tight panel design.

Fall protection is essential on every project, but it becomes even more critical when crews work on DMI's standing seam panels. These systems rely on precise seam engagement and concealed clips that support the roof and maintain its weather-tight seal. When workers attach equipment that crushes the seam or pierces the metal, the roof can lose that protective integrity.

Contractors avoid these issues by choosing non-penetrating anchors designed for standing seam roofs. SSRA1 Seam Anchors grip the seam with non-penetrating stainless steel set screws, providing workers with a reliable single-worker tie-off point. The removable d-ring on top allows the SSRA system to expand with the addition of adapter plates. When crews need a stable work platform, SSRA2 Roof Jack Adapters mount on top of SSRA1 anchors and support a 10-foot walkboard, allowing roofers to work confidently on steep DMI panel runs. Multi-worker protection starts with SSRA3 Anchor Plates, which create attachment points for temporary horizontal lifelines. Workers can move safely on larger roof areas with the SSRA HLL 100-foot Temporary Horizontal Lifeline Kit without penetrating the panels.

Some buildings require long-term access for HVAC service or maintenance checks. In those situations, the Super Anchor 120-foot Permanent Horizontal Lifeline Kit provides facility teams with a ready-made system that stays in place year-round, eliminating the need to reinstall temporary anchors on mechanically seamed standing seam roofs.

Crews working on steeper DMI roofs stay safer with the Ridge Pro Steep Assist. It hooks over the ridge without penetrating the panel and keeps workers tied off on slopes from 6:12 to 12:12. The tool also covers the critical zone where workers transition from the ladder to the ridge. The Ridge Pro is an excellent alternative to seam-mounted anchors for copper and aluminum panels.

Matching the fall protection equipment to the seam shape keeps crews secure, preserves DMI's premium panel finish, and helps projects move forward safely and efficiently.

Span-Lock SL25 Mechanical Panel

The Span-Lock SL25 from Dimensional Metals, Inc. delivers a structural standing seam system for roofs, vertical fascia, mansards, equipment screens, and select wall applications.

Installers appreciate how this panel adapts to different substrates, including open framing, rigid insulation, corrugated steel decks, plywood, and nail-base insulation. See the Roof Anchor Compatibility Chart for Span-Lock SL25 Dimensional Metals 22 Gauge and 24 Gauge Standing Seam Panels.

DMI offers two seam spacings: 12-inch on-center and 16-inch on-center seams. The panel comes in 24-gauge and 22-gauge steel, and in .032- and .040-inch aluminum for projects that need lighter materials. Testing for UL-580 wind uplift, ASTM air and water resistance, and overall structural performance indicates that the SL25 performs well in demanding environments.

Factory-applied non-curing sealant supports watertight performance, and expansion clips allow thermal movement. Hence, the roof stays smooth and uniform over time. Installers can use the SL25 on slopes as low as 1/2:12 without hand-seaming, making the system practical for a broad range of designs.

Fall Protection For Span-Lock SL25 Panels

The SSRA1 Standing Seam Roof Anchor provides the most secure non-penetrating tie-off point for SL25 panels formed from 22-gauge and 24-gauge steel.

It maintains the roof's weather-tight seal and gives workers a dependable anchorage point. When crews need a stable platform, the SSRA2 Adjustable Roof Jack Adapter mounts on top of SSRA1 anchors and supports a 10-foot walkboard, allowing workers to move across steep panels with confidence. SSRA3 Anchor Plates also mount to SSRA1 anchors and provide a solid attachment point for temporary horizontal lifelines.

For extended coverage along SL25 panel runs, safety managers can deploy the SSRA HLL 100-foot Temporary Horizontal Lifeline Kit. This kit protects multiple workers simultaneously and maintains a clean installation on standing-seam roofs. Buildings that require recurring access benefit from the Super Anchor 120-foot Permanent Horizontal Lifeline Kit, which gives maintenance crews a ready-made tie-off point year-round without penetrating the roof.

Aluminum SL25 panels require a different approach. These materials do not support seam-mounted anchorage, so the Ridge Pro Steep Assist Anchor becomes the recommended solution. It hooks securely over the ridge and provides a stable, non-penetrating tie-off point on slopes from 6:12 to 12:12. This keeps workers safely connected on steeper projects while protecting the roof surface and seam shape.

Span-Lock SL20 Mechanical Panel

The Span-Lock SL20 panel delivers structural performance on low-slope roofs while keeping a clean architectural look across long panel runs.

The Span-Lock SL20 from Dimensional Metals, Inc. gives contractors a structural standing seam option that works on everything from low-slope roofs to steeper applications. See the Roof Anchor Compatibility Chart for Span-Lock SL20 Dimensional Metals 22 Gauge and 24 Gauge Standing Seam Panels.

Nuanced sizing options make this panel flexible in the field. The three panel width options include 12-inch, 16-inch, and 17.625-inch. All three versions use a 2-inch rib height, which helps the system handle weather and loading while still presenting a sharp vertical line.

DMI forms the Span-Lock SL20 in 22-gauge and 24-gauge steel, aluminum, and copper. A factory-applied non-curing sealant improves watertightness at the seam, and expansion clips allow the panels to move as temperatures change without stressing the seam shape. The system can be mechanically seamed and installed at a 1/2:12 pitch. Continuous roll-formed lengths eliminate panel lap joints, keeping the roof smooth and consistent.

Fall Protection For Span-Lock SL20 Panels

SSRA anchors protect 22-gauge and 24-gauge steel SL20 panels, while the Ridge Pro covers aluminum and copper versions on steeper slopes.

On straight Span-Lock SL20 roofs formed from 22-gauge or 24-gauge steel, the SSRA1 Standing Seam Roof Anchor gives crews a dependable non-penetrating tie-off point. The anchor clamps to the seam without drilling into the metal, so the roof maintains its weather-tight seal.

When walkboards are needed, the SSRA2 Adjustable Roof Jack Adapters mount on top of SSRA1 anchors and support a 10-foot plank. That setup provides installers with a stable, working platform across steep panel runs. SSRA3 Anchor Plates also mount on SSRA1 anchors and create strong attachment points for temporary horizontal lifelines.

For extended coverage, safety managers can add the SSRA HLL 100-foot Temporary Horizontal Lifeline Kit to keep multiple workers protected across large roof areas. When the building needs long-term access for inspections or maintenance, the Super Anchor 120-foot Permanent Horizontal Lifeline Kit turns the SL20 roof into a permanent tie-off corridor that stays ready whenever crews return.

Aluminum and copper Span-Lock SL20 panels require a different strategy because these substrates do not support seam-mounted anchors. In those cases, the Ridge Pro Steep Assist Anchor becomes the recommended option. It hooks over the ridge and creates a stable, non-penetrating tie-off point on slopes between 6:12 and 12:12, keeping workers connected from the ladder to the ridge and back again.

If any project includes curved roof sections or unusual transitions, a trained safety professional should review the layout and specify the most appropriate fall protection.

Tee-Lock TL25 Panel T-Seam Panel

The TL25 panel delivers strength, flexibility, and installation efficiency across a wide range of DMI applications.

Dimensional Metals, Inc. manufactures the Tee-Lock TL25 as a structural standing seam panel that adapts easily to many project types. This bi-directional panel installs in either direction, helping crews keep production moving smoothly on complex layouts. DMI offers the TL25 in three seam spacings. TL2512 provides 12-inch centers, TL2516 uses 16-inch centers, and TL2518 offers 17.625-inch centers. All versions feature a 2.5-inch T-shaped seam profile. See the Roof Anchor Compatibility Chart for Span-Lock TL25 Dimensional Metals 22 Gauge and 24 Gauge Standing Seam Panels.

Material options include 24-gauge and 22-gauge steel, as well as .032-inch and .040-inch aluminum. Builders often use the TL25 on low-to-high slope roofs, vertical fascia, mansards, equipment screens, and wall applications. A factory-applied hot-melt sealant enhances the panel's watertight performance, and the hydrostatic seam allows use on slopes as low as 1/2:12.

The TL25 panels use a one-piece clip that manages unlimited thermal movement. That feature helps the roof system stay stable through seasonal temperature swings. The system also allows individual panel removal and replacement. That versatility makes it easier for owners and maintenance teams when future repairs or modifications are required.

Fall Protection For Tee-Lock TL25 Panels

The SSRA1 Standing Seam Roof Anchor works well on TL25 panels formed from 22-gauge and 24-gauge steel. This anchor clamps to the seam without penetrating the metal, providing workers with a safe, stable tie-off point that preserves the panel's weather-tight design.

The SSRA2 Adjustable Roof Jack Adapter mounts on top of the SSRA1 anchors when crews need a walkboard. It supports a 10-foot plank and lets teams work from a level surface while keeping the seam intact.

The SSRA3 Anchor Plates also mount on top of the SSRA1 anchors. They create strong connection points for temporary horizontal lifelines. When paired with the Malta Dynamics HLL3001 100-foot Horizontal Lifeline Kit, the SSRA3 setup supports two workers along longer roof runs.

For buildings that require ongoing rooftop access, the Super Anchor 120-foot Permanent Horizontal Lifeline Kit becomes the preferred long-term solution. It gives maintenance crews a ready-made tie-off point without penetrating the standing seam roof.

Aluminum TL25 panels require a different approach. The Ridge Pro Steep Assist Anchor becomes the better option for those materials. It hooks over the ridge and provides a secure tie-off point on slopes from 6:12 to 12:12. Workers stay tied off during the transition from the ladder to the ridge and throughout the job.

These solutions protect workers while preserving DMI's panel performance and appearance. The proper anchors keep the TL25 system intact and help contractors maintain the standards expected from Dimensional Metals, Inc.

Inter-Lock IL20 Snaplock Panel

The Inter-Lock IL20 panel combines a snap-together seam with structural strength for DMI roofs that need clean lines and durability.

Dimensional Metals, Inc. offers the Inter-Lock IL20 as a structural standing seam system that snaps together instead of relying on field seaming. Panel widths include 12-inch, 16-inch, and 17.75-inch options. The 1.75-inch rib height gives the panel a strong profile, and the snaplock connection helps crews move quickly across the deck while still landing a secure installation. DMI produces IL20 in 22-gauge and 24-gauge steel, aluminum, and copper so that contractors can match the substrate to the project's structural and aesthetic needs. When jobs call for long panel runs, DMI can roll the IL20 in continuous lengths up to 70 feet. See the Roof Anchor Compatibility Chart for Span-Lock IL20 Dimensional Metals 22 Gauge and 24 Gauge Standing Seam Panels.

Fall Protection For Inter-Lock IL20 Panels

SSRA anchors and ridge-mounted systems give Inter-Lock IL20 projects safe, non-penetrating tie-off options that match each substrate.

On steel versions of the Inter-Lock IL20 in 22-gauge and 24-gauge, SSRA1 seam anchors create a strong non-penetrating tie-off point by clamping directly to the standing seam without piercing the metal. Crews can mount SSRA2 Adjustable Roof Jack Adapters on top of the SSRA1 anchors when they need 10-foot walkboards, providing workers with a solid platform for moving tools and materials along panel runs. SSRA3 Anchor Plates also sit atop SSRA1 anchors and serve as the base for temporary horizontal lifelines.

When projects need full-run coverage, the SSRA HLL 100-foot Temporary Horizontal Lifeline Kit protects multiple workers along long IL20 roof sections. Building owners who expect ongoing access for maintenance can step up to the Super Anchor 120-foot Permanent Horizontal Lifeline Kit, which stays in place year-round and turns the IL20 roof into a ready-made tie-off route for future inspections.

Aluminum and copper IL20 panels call for a different approach because those substrates do not support seam-mounted anchors the same way heavier steel does. In those cases, the Ridge Pro Steep Assist Anchor becomes the recommended solution. It hooks over the ridge and creates a stable, non-penetrating tie-off point on slopes between 6:12 and 12:12, helping workers stay connected from the ladder to the ridge and back again without putting extra stress on the snaplock seam or the panel surface.

Double-Lock DL25 Mechanical Panel

Dimensional Metals, Inc. builds the Double-Lock DL25 for jobs that need strength, watertight seams, and dependable long-term performance.

This mechanically seamed profile works on everything from low-slope roofs at 1/2:12 to vertical fascia, equipment screens, mansards, and wall applications. Contractors can choose between two seam spacing options: DL2512 with 12-inch on-center seams or DL2516 with 16-inch on-center seams. Both versions include 2.5-inch ribs, a factory-applied non-curing sealant for watertightness, and expansion clips that help the roof move naturally as temperatures change. See the Roof Anchor Compatibility Chart for Span-Lock DL25 Dimensional Metals 22 Gauge and 24 Gauge Standing Seam Panels.

DMI forms the DL25 in 22-gauge and 24-gauge steel, along with .032-inch and .040-inch aluminum, so architects and roofing crews can match the panel to the structure's performance requirements and budget. Continuous roll-formed lengths eliminate lap joints, improving the roof system's clean look and overall reliability.

Fall Protection for Double-Lock DL25 Panels

Anchors must match the panel material and slope to keep crews safe without damaging the seam profile.

Steel versions of the DL25 pair well with the SSRA1 Standing Seam Roof Anchor without risk of penetration. The SSRA1 provides crews with a dependable tie-off point that maintains the roof system's weather-tight performance. When workers need walkboards, the SSRA2 Adjustable Roof Jack Adapters mount on top of the SSRA1 and support a 10-foot plank, which creates a safer platform for steep panel runs or tool staging.

For mobility across wider DL25 roof areas, crews can mount SSRA3 Anchor Plates on the SSRA1 anchors to run temporary horizontal lifelines. The Malta Dynamics HLL3001 100-foot Horizontal Lifeline Kit works well in these situations and supports up to two workers who need safe movement along the system.

Facilities that expect repeated access for inspections, rooftop equipment checks, or routine service often benefit from a long-term solution. The Super Anchor 120-foot Permanent Horizontal Lifeline Kit meets this need by providing building owners with a stable, ready-to-use tie-off system that does not penetrate the roof. It stays in place year-round, reducing setup time for every future visit.

Aluminum DL25 panels call for a different approach. Aluminum panels can't support seam-mounted anchors, so the Ridge Pro Steep Assist is the right choice for slopes from 6:12 to 12:12. It hooks over the ridge, creating a secure connection point that keeps workers tied off as they transition from the ladder to the roof or navigate steeper pitches.

Used correctly, these systems protect workers, preserve the panel, and support the long-term performance for which DMI's Double-Lock DL25 is known.

Double-Lock DL20 Mechanical Panel

The DL20 panel delivers strength, flexibility, and a dependable fit across a wide range of project types.

Dimensional Metals, Inc. builds the Double-Lock DL20 as a structural standing-seam panel suitable for an impressive range of applications. Contractors use it on low-slope roofs, steep-slope roofs, vertical fascia, equipment screens, mansards, and even curved or tapered surfaces. The DL20 forms a tight, interlocking seam that crews mechanically finish during installation, ensuring long-term weather performance. See the Roof Anchor Compatibility Chart for Span-Lock DL20 Dimensional Metals 22 Gauge and 24 Gauge Standing Seam Panels.

The panel comes in several seam spacing options. DL2012 has 12-inch on-center seams, DL2016 has 16-inch centers, and DL2018 uses 17.625-inch centers. All versions share a 2-inch rib height that balances strength with a clean visual profile. Material choices include 22-gauge and 24-gauge steel for structural work, as well as aluminum, copper, and zinc. This range lets builders match the DL20 to the budget and the design style of almost any project.

Fall Protection For Double-Lock DL20 Panels

Compatible anchors protect the roof and give crews safe mobility from the moment work begins.

The DL20 performs best when fall-protection equipment matches the exact substrate. On 22-gauge and 24-gauge steel panels, the SSRA1 Standing Seam Roof Anchor delivers the strongest option. It grips the seam without penetrating the metal, preserving the DL20's weather-tight design and providing workers with a stable tie-off point they can trust. When crews need a working platform, the SSRA2 Adjustable Roof Jack Adapter mounts on top of the SSRA1 and supports a 10-foot walkboard, allowing workers to move safely along steep panel runs.

For projects where multiple workers require mobility, the SSRA3 Anchor Plates mount to the SSRA1 anchors and provide secure attachment points for temporary horizontal lifelines. For larger roof projects, the Malta Dynamics HLL3001 100-foot Horizontal Lifeline Kit delivers a reliable setup that protects up to two workers across long DL20 roof sections.

Facilities that see repeated service work benefit from a permanent system. The Super Anchor 120-foot Permanent Horizontal Lifeline Kit gives maintenance teams a ready-made tie-off point year-round without penetrating the standing seam. It shortens setup time and keeps the DL20 roof intact long after the project wraps up.

For DL20 panels made of aluminum, copper, or zinc, the Ridge Pro Steep Assist Anchor is the best option. It hooks over the ridge and provides a dependable non-penetrating tie-off point on slopes from 6:12 to 12:12. Workers stay tied off the entire time they move from the ladder to the ridge and back again, which is especially important on smooth architectural metals that cannot accept compression-based anchors.

By pairing each DL20 panel type with the right anchor system, contractors create a safer work environment and maintain the long-term performance that Dimensional Metals, Inc. expects from its standing seam products.

Ultra-Lock UL20 Snaplock Panel

The UL20 panel blends architectural clean lines with a fast and secure snap-together installation.

Dimensional Metals Inc. created the Ultra-Lock UL20 for projects that need a clean architectural look without sacrificing performance. The snap-together seam locks into place during installation, providing crews with a fast, dependable way to build long panel runs. DMI offers this panel in several materials, including 24-gauge and 22-gauge steel and aluminum. Customers can also choose between widths of 12 inches, 16 inches, and 17.625 inches. The profile forms a 1-3/4-inch seam height, giving the panel a tight architectural appearance while still withstanding weather exposure. See the Roof Anchor Compatibility Chart for Span-Lock UL20 Dimensional Metals 22 Gauge and 24 Gauge Standing Seam Panels.

DMI tests every panel line it manufactures, and the UL20 follows the same path with engineering review and performance verification before it ever reaches the jobsite. That testing gives owners and contractors the confidence that the panel will hold up over time, even on challenging architectural designs.

Fall Protection For Ultra-Lock UL20 Panels

The proper anchors protect the UL20 seam shape while giving crews dependable tie-off points.

Steel UL20 panels in 22-gauge and 24-gauge thickness work very well with the SSRA1 Standing Seam Roof Anchor.

This anchor grips the seam with stainless set screws rather than penetrations, providing crews with a solid tie-off point without compromising the weather-tight design. When walkboards are needed, the SSRA2 Adjustable Roof Jack Adapter mounts on top of the SSRA1. It holds a 10-foot plank, allowing workers to move steadily across steep roof areas. Whenever safety managers need to set up temporary horizontal lifelines, the SSRA3 Anchor Plates mount on the SSRA1 and provide the correct attachment point for lifeline hardware.

The SSRA HLL 100-foot Temporary Horizontal Lifeline Kit ties the system together for multi-worker mobility. It protects crews as they travel across spans that would typically require several individual anchors. When a building needs long-term access for inspections or maintenance, the Super Anchor 120-foot Permanent Horizontal Lifeline Kit becomes the better option. This system stays in place permanently and gives facility teams a ready-to-use tie-off method without interrupting the standing seam roof.

For aluminum UL20 panels, the Ridge Pro Steep Assist Anchor is the best anchor option. It hooks over the ridge and offers a stable tie-off point on slopes from 6:12 to 12:12. The Ridge Pro gives workers secure access from the ladder to the ridge and back again while protecting the softer panel materials from over-compression.

With properly matched anchors for each UL20 material type, workers stay tied off, seams remain protected, and every project moves forward with confidence.

Double-Lock DL15 Mechanical Panel

The Double-Lock DL15 from Dimensional Metals, Inc. gives builders a dependable structural standing seam option that performs well across a broad mix of roof designs.

This panel uses a mechanically seamed interlocking system that locks the ribs into a tight, durable profile, making it suitable for low- to high-slope roofs, vertical fascia, equipment screens, mansards, and even curved or tapered areas. Material choices include 24-gauge steel, aluminum, copper, and zinc, with each version offering its own span strength and aesthetic options. DMI also provides several seam spacings to match project layout needs, including 12, 17, and 20 inches on-center. Every DL15 panel includes a factory-applied non-curing sealant for watertight performance. It uses hidden clips that let the roof move naturally with temperature changes. Continuous roll-formed lengths reduce the need for panel laps, and the 1.5-inch rib height ties everything together into a clean profile that installs efficiently. See the Roof Anchor Compatibility Chart for Dimensional Metals DL15 Standing Seam Panels.

Fall Protection For Double-Lock DL15 Panels

Crews working on 24-gauge steel versions can rely on the complete non-penetrating SSRA system.

The SSRA1 Standing Seam Roof Anchor grips the rib cleanly without piercing the metal, giving workers a strong tie-off point that keeps the DL15 profile intact. When workers need a temporary walkway, an SSRA2 Roof Jack Adapter mounts on top of any SSRA1 anchor and supports a 10-foot walkboard, allowing crews to work safely on steep roof areas. The same anchor can also accept an SSRA3 plate, which creates the connection point needed for temporary horizontal lifelines. Long roof runs that require two-worker mobility pair well with the SSRA3 and the Malta Dynamics HLL3001 100-foot Horizontal Lifeline Kit, providing continuous coverage as installers move across the DL15 system.

Some buildings require long-term roof access after construction, which is where the Super Anchor 120-foot Permanent Horizontal Lifeline Kit helps. Maintenance crews gain a ready-to-use tie-off system without adding roof penetrations, and building owners benefit from year-round, consistent OSHA-compliant access.

For aluminum, copper, or zinc DL15 panels, the Ridge Pro Steep Assist becomes the safer choice. These materials cannot accept compression-style seam anchors, so the Ridge Pro hooks over the ridge and provides a stable non-penetrating tie-off point on pitches from 6:12 to 12:12. Workers stay tied off from the ladder to the ridge and back again, which is especially important on steeper metal surfaces or during early access before the first clip is secured.

By using these matched fall-protection approaches, contractors protect their crews while preserving the roof's integrity and meeting DMI's performance expectations on every DL15 installation.

Curved Tee-Lock CR-TL25 Panel (Not Compatible With SSRA Products)

DMI offers the CR-TL25 in the same seam spacing configurations as the straight Tee-Lock system.

Installers can choose from 12-inch, 16-inch, or 17.625-inch on-center seams, all formed with a 2.5-inch t-shaped rib. Material choices include 24-gauge or 22-gauge steel, along with .032 and .040 aluminum to match project requirements. A factory-applied hot-melt sealant supports water control, and the hydrostatic seam profile allows installers to work on slopes down to 1/2:12. The one-piece clip also allows thermal expansion. It makes individual panel replacement possible if the roof ever needs repairs. See the Roof Anchor Compatibility Chart for Dimensional Metals CR-TL25 Standing Seam Panels.

Curved panels are always a specialty installation, so DMI's radiused Tee-Lock lineup gives contractors a reliable way to match curved designs without sacrificing strength or longevity.

Fall Protection For Curved Tee-Lock CR-TL25 Panels

The safest approach is simple: a trained fall-protection professional must inspect the curved roof in person before anyone climbs onto the panel.

Curved surfaces often require anchors installed in locations that behave differently under load. Hence, a custom plan tailored to that specific roof keeps crews safer than any off-the-shelf recommendation.

Once the evaluation is complete, the safety professional will map out the right combination of temporary anchors, rated attachment points, and lifeline paths that align with the roof's curvature. This personalized approach protects workers and the roof, preventing the damage that incompatible equipment can cause.

Curved Double-Lock CR-DL20 Panel (Not Compatible With SSRA Products)

Dimensional Metals, Inc. offers the Curved Double-Lock CR-DL20 for projects where standard straight panels cannot deliver the look or performance required.

This panel provides strength and architectural flexibility for curved roofs, such as barrel vaults, arched canopies, and large mansards, that require smooth transitions without sacrificing durability. The CR-DL20 uses the same interlocking mechanical seam style as the straight DL20 panels, but for curved installations, ensuring the finished surface flows cleanly from one end to the other. See the Roof Anchor Compatibility Chart for Dimensional Metals CR-DL20 Standing Seam Panels.

Steel versions are available in 24-gauge and 22-gauge, with three seam spacing options: DL2012 at 12 inches on-center, DL2016 at 16 inches on-center, and DL2018 at 17.625 inches on-center. Aluminum panels are available in .032 and .040 thicknesses, with 12-inch or 18-inch spacing. Copper versions come in 16-ounce or 20-ounce weights with 12-inch or 18-inch seams for projects that demand a premium architectural finish. All versions feature 2-inch ribs that help define the roof profile and give the panel a stiff, uniform shape.

Fall Protection for Curved Double-Lock CR-DL20 Panels (Not Compatible With SSRA Products)

Curved CR-DL20 roofs require a safety approach that differs from anything used on straight standing seam panels. Because of this, workers should not use SSRA seam-mounted anchors or the Ridge Pro Steep Assist on curved versions of the DL20 panel.

The safest path forward always begins with an in-person inspection by a trained fall-protection professional. That assessment determines whether the project requires a beam clamp, a strap-based anchorage, a temporary horizontal system supported by a structural member, or a fully engineered tie-off plan.

By coordinating with a trained safety professional and selecting equipment that matches the unique shape of the CR-DL20 roof, contractors create a safer job site and preserve the visual quality and long-term performance that make curved panels such a distinctive DMI offering.

Curved Double-Lock CR-DL15 (Not Compatible With SSRA Products)

Dimensional Metals, Inc. manufactures the Curved Double-Lock CR-DL15 for projects that need a smooth, flowing roofline rather than standard straight panel runs.

This panel brings the traditional double-lock aesthetic to curved applications, giving architects ample freedom to shape barrel roofs, sweeping canopies, and rounded architectural details. The CR-DL15 is available in panel widths of 12.5, 17, and 20 inches, with a rib height of 1.5 inches. It can maintain a minimum radius of 12 feet, making it a practical option for tighter curves and more expressive shapes. See the Roof Anchor Compatibility Chart for Dimensional Metals CR-DL15 Standing Seam Panels.

Material choices cover a wide range of project needs. Customers can select 24-gauge steel, .032 aluminum, or 16-ounce and 20-ounce copper. These metals provide a long service life and allow the CR-DL15 to suit a range of design budgets.

Fall Protection For Curved Double-Lock CR-DL15 Panels

A trained safety professional needs to walk the roof to determine how workers will access and move across each section. A site-specific evaluation ensures the chosen anchorage protects the workers and does not deform or overload the curved metal panels.

With proper assessment and a tailored fall protection plan, contractors can work safely on CR-DL15 installations while maintaining the roof's shape and performance.

Curved Snap-On-Seam CR-SS10 (Not Compatible With SSRA Products)

The Curved Snap-On-Seam CR-SS10 from Dimensional Metals, Inc. brings smooth arcs and graceful lines to projects that need curved roof elements.

This system blends an architectural look with dependable performance, which is why it shows up so often on barrel vaults, sweeping canopies, and curved soffit work. The panel uses a two-piece configuration with a structural base and a snap-on seam cover that finishes the profile and protects the connection. See the Roof Anchor Compatibility Chart for Dimensional Metals CR-SS10 Standing Seam Panels.

DMI offers the CR-SS10 in three panel setups. Contractors can choose seam spacing of 12, 16, or 18 inches. All versions use a 1-inch rib height. The panels come in 24-gauge and 22-gauge, aluminum and copper. Matching seam caps are supplied in steel, aluminum, or copper to complete the system. Installers need a solid deck, such as plywood, nail base insulation, or corrugated metal, because the CR-SS10 relies on a firm substrate for correct attachment.

Fall Protection For Curved Snap-On-Seam CR-SS10 Panels

Curved Snap-On-Seam panels call for a different approach to fall protection. The safest path forward starts with an in-person inspection by a trained safety professional.

A qualified evaluator can determine whether the job needs an engineered lifeline layout, a temporary overhead system, or another specialized method that maintains both worker safety and the integrity of the curved metal roof. This customized assessment provides crews with the proper tie-off plan before any work begins and protects the roof from damage during installation or maintenance.

Snap-On-Seam SS10 Batten-Cover Panel (Not Compatible With SSRA Products)

Dimensional Metals, Inc. (DMI) produces the Snap-On-Seam SS10, a non-structural metal roof panel built around a simple two-piece design.

Each section includes a pan and a snap-on seam cover that locks into place during installation. Panel widths include 12", 16", and 18", all formed with a 7/8" seam height. The SS10 comes in 22-gauge and 24-gauge steel, .032 and .040 aluminum, and 16-ounce and 20-ounce copper, giving designers plenty of options for color, style, and performance. This system works well on roofs, fascia, and soffit applications where a clean architectural look matters more than structural capacity. See the Roof Anchor Compatibility Chart for Dimensional Metals SS10 Standing Seam Panels.

Fall Protection For Snap-On-Seam SS10 Panels

The SS10 relies on a complete batten-cover design, which prevents any seam-mounted system, such as the SSRA1, SSRA2, or SSRA3, from attaching correctly.

For this reason, the Ridge Pro Steep Assist is the safest and most reliable choice for working on these panels. The Ridge Pro hooks securely over the ridge. It gives workers a stable tie-off point on slopes from 6:12 to 12:12. Because the ridge connection keeps pressure off the batten covers, crews can move up and down the roof without stressing the panel system or risking seam distortion. This setup gives installers the stability they need during access and transition work while protecting the roof's appearance and long-term performance.

Snap-On-Seam SS15 Panel (Not Compatible With SSRA Products)

The Snap-On-Seam SS15 from Dimensional Metals, Inc. delivers a clean architectural look with a simple snap-together installation. DMI offers the SS1512 (12-inch seams), SS1516 (16-inch seams), and SS1518 (18-inch seams), giving designers several layout options based on appearance and panel spacing.

Contractors can choose from 24-gauge and 22-gauge steel, .032 and .040 aluminum, or 16-ounce and 20-ounce copper. That range makes the SS15 system adaptable for everything from light commercial work to detailed architectural features. These panels perform well on roofs with slopes as low as 3:12. They are also commonly used on vertical fascia, mansards, curved transitions, and equipment screens where appearance matters as much as function. The SS15's snap-on seam cover conceals fasteners and creates a uniform finished look across longer runs. See the Roof Anchor Compatibility Chart for Dimensional Metals SS15 Standing Seam Panels.

Fall Protection for Snap-On-Seam SS15 Panels

The Ridge Pro Steep Assist Anchor is the best fall protection anchor for the SS15 system. Its ridge-mounted setup avoids attachment to the snap-on seam covers.

The Ridge Pro connects from the ladder to the ridge and back again, providing a secure tie-off point without disturbing the panel seams or risking damage to the seam cover. This approach keeps crews safe on slopes from 6:12 to 12:12 and preserves the architectural finish that makes the SS15 system popular.

Dome & Compound Curve CC10 Panel (Not Compatible With SSRA Products)

The Dome & Compound Curve CC10 from Dimensional Metals, Inc. provides a specialty solution for projects that require panels shaped for spherical domes, rounded canopy edges, and other tight-radius architectural features.

This system gives designers the freedom to follow complex curves without sacrificing durability or weather performance. DMI offers the CC10 in several substrates, including 24-gauge and 22-gauge steel, .032 and .040 aluminum, and 16-oz and 20-oz copper. Material selection depends on the level of rigidity, corrosion resistance, and visual finish required by the project. The snap-together design allows installers to work the panels into tight curves while keeping the system secure once locked in place. See the Roof Anchor Compatibility Chart for Dimensional Metals CC10 Standing Seam Panels.

A built-in anti-siphoning seam helps prevent water infiltration. In contrast, the continuous interlocking seam cap reduces any risk of seam disengagement. Radius capability varies by material. A 24-gauge steel panel can bend to a minimum convex radius of 3 feet, a 22-gauge steel panel to 8 feet, and a .032 aluminum panel to 2 feet 6 inches.

Because these panels can also be custom-fabricated, contractors can match precise curves and contours on domes, soffits, and compound-slope designs. That flexibility is what makes the CC10 one of DMI's most useful curved-system options.

Fall Protection for Dome & Compound Curve CC10 Panels

The CC10's shape prevents the safe use of SSRA seam anchors and Ridge Pro ridge-mounted systems because neither product can maintain proper alignment or distribute load correctly on curved surfaces.

For that reason, a trained safety professional must examine the project in person before selecting a fall protection strategy. The inspection focuses on the roof's radius, panel direction, access points, and expected work zones. From there, the safety professional will determine which anchorage methods, lifeline layouts, or temporary systems match the building's curved surfaces.

Batten-Seam BS15 (Box-Batten) Panel (Not Compatible With SSRA Products)

Dimensional Metals, Inc. (DMI) manufactures the Batten-Seam BS15, a non-structural box-batten system composed of two components: the continuous panel and the snap-on batten cap.

Because the battens are not direction-dependent, installers can lay out the system in either direction and maintain consistent visual spacing across the entire roof. This feature makes the BS15 a popular choice for architectural projects where symmetry and appearance matter as much as performance. See the Roof Anchor Compatibility Chart for Dimensional Metals BS15 Standing Seam Panels.

The system comes in three panel widths, including 12 inches, 16 inches, and 18 inches. All three versions feature a 1.5-inch seam height. Material options range from 24-gauge and 22-gauge steel to aluminum and copper.

Fall Protection For Batten-Seam BS15 Panels

Batten-style seams do not accept seam-mounted anchors, so crews must use alternative safety methods.

The Ridge Pro Steep Assist Anchor remains the most practical option. It hooks over the ridge to create a secure tie-off point without relying on the seam shape, giving workers a stable way to move from the ladder to the peak and back again. This anchor works exceptionally well on BS15 installations where the batten caps prevent any compression-style or clamp-style attachment.

By selecting equipment that respects the batten-cap design and avoids seam compression, contractors protect both their crews and the architectural finish of the BS15 roof.

Nail-Strip NS15 Panel (Not Compatible With SSRA Products)

The Nail-Strip NS15 from Dimensional Metals, Inc. offers a clean architectural look and simple installation.

Its snap-together design eliminates the need for mechanical seaming, making it a popular choice for residential and light commercial work. The NS15 comes in two panel widths, 10-5/8 inches and 18 inches, with a seam height of 1-1/2 inches that gives the roof a crisp, modern profile. You can order this panel in 24-gauge steel or .032 aluminum, allowing it to match the durability needs of different projects. DMI also produces the NS15 in lengths ranging from 3 feet to 40 feet, helping installers plan efficient layouts without excessive joints. Since this is a non-structural panel, it relies entirely on a solid substrate for support. See the Roof Anchor Compatibility Chart for Dimensional Metals NS15 Standing Seam Panels.

Fall Protection For Nail-Strip NS15 Panels

The seam shape of the NS15 does not accept clamp-style anchors, so SSRA equipment and the 120-foot permanent lifeline kit are not compatible.

The best option is the Ridge Pro Steep Assist, which hooks over the ridge and provides a stable tie-off point. At the same time, workers climb, transition, and work on slopes from 6:12 to 12:12. Its ridge-mounted connection eliminates seam pressure and protects the panel shape. Because nailstrip systems lock together with a snap feature rather than a structural seam, a ridge-mounted anchor provides the safest and most predictable access method.

Nail-Strip NS10 Panel (Not Compatible With SSRA Products)

Dimensional Metals, Inc. also manufactures the Nail-Strip NS10, a versatile panel with a continuous interlocking seam that snaps securely into place during installation.

The NS10 comes in two seam spacings, NS1012 at 11.625 inches on center and NS1018 at 18 inches on center. Both versions feature a 1-inch rib height, delivering a smooth, finished appearance once installed. These panels are available in 24-gauge steel or .032 aluminum. Designed for use over solid substrates such as plywood or metal decking, the NS10 installs with fasteners that run along the nail flange, spaced up to 20 inches on center. It works well on minimum slopes of 3:12 and adapts easily to vertical fascia, mansards, and wall panel applications. See the Roof Anchor Compatibility Chart for Dimensional Metals NS10 Standing Seam Panels.

Fall Protection For Nail-Strip NS10 Panels

The NS10 seam does not support seam-mounted anchors, so workers cannot use SSRA1, SSRA2, SSRA3, and the 120-foot permanent lifeline kit.

The Ridge Pro Steep Assist becomes the correct choice for this panel. It hooks over the ridge, stays off the seam entirely, and provides workers with a stable tie-off point for safe access on slopes from 6:12 to 12:12. Its ridge-mounted approach meets the needs of nailstrip installations and keeps the locking seam undisturbed. This method provides dependable protection while preserving the look and long-term performance of the NS10 panel system.

Safety Tips For Standing Seam Roofs

Promote a Culture of Safety

A strong safety culture makes every DMI roof project run smoothly. A quick huddle before anyone climbs a ladder gives crews a chance to talk through the day's plan, review roof access paths, and call out anything unusual about the panel layout or weather. When roofers feel comfortable speaking up, the entire team stays safer.

Install Permanent Roof Anchor Systems

Facilities roofed with DMI's structural standing seam systems often require repeat access for HVAC, solar maintenance, or equipment checks. A permanent horizontal lifeline gives technicians a reliable, ready-made tie-off point every time someone steps onto the roof. These systems stay in place year-round, reducing setup time and eliminating the guesswork of temporary anchors. Because the anchor layout never changes, maintenance crews can focus on the task at hand rather than rethinking fall protection at every visit.

Equip Workers with High-Quality Safety Gear

OSHA requires workers to have gear that fits well and performs properly. A harness that fits correctly, connectors that snap and lock in place, and SRLs like the Malta Dynamics Pygmy Hog or Edgehog that feed smoothly give workers the confidence they need on steeper pitches or long spans. When crews take 30 seconds at the start of each shift to check leg straps, chest buckles, and SRL retraction, the entire jobsite works cleaner and with fewer surprises.

Consult Experts for Curved Metal Panels

Curved DMI panels introduce unique challenges for project managers. A trained fall-protection specialist should evaluate the roof system, panel material, and access areas in person to determine the safest approach. Their recommendations often include customized anchor points, engineered lifeline paths, or specialty hardware that protects both the worker and the curved panels. This consultation step saves time, reduces liability exposure, and prevents damage to some of DMI's most specialized roofs.

Develop OSHA-Compliant Safety Plans

A written safety plan gives workers a roadmap long before the first anchor touches metal. It outlines where lifelines will be located and who will be responsible for rescue. Different DMI systems often require different approaches, so updating the plan as weather shifts or access paths change keeps everyone aligned. A good plan takes the guesswork out of the workday.

Use Specialized Anchor Systems for Standing Seam Roofs

Steel versions of DMI's mechanical-lock and snaplock profiles are compatible with seam-mounted anchors, but only when those anchors clamp correctly and protect the painted finish. Using the right equipment prevents seam distortion and eliminates the risk of hidden-clip damage. On projects where the roof cannot accept seam-mounted anchors—such as aluminum, copper, or batten-style systems—crews rely on ridge-mounted systems like the Ridge Pro to stay tied off without harming the panels.

Encourage the Use of Trauma Straps

A fall arrest isn't the end of the danger. Suspension trauma can set in quickly, especially when workers are hanging from a full-body harness while waiting for rescue. Trauma straps give the suspended worker a way to stand, shift weight, and restore leg circulation long enough for the rescue team to reach them. They weigh next to nothing, cost little, and should be part of every roofer's harness setup when working on DMI profiles.

Ensure Proper Footwear for Stability

Safe footing is critical on DMI's smooth painted steel and aluminum surfaces. Roofing-grade boots with firm ankle support and slip-resistant soles help workers stay stable on steeper pitches or during early-morning dew. Worn-down soles or athletic shoes reduce grip and increase the risk of slipping, especially on steep panel runs. Good footwear keeps crews steady and reduces fatigue during long days on standing seam systems.

Prioritize Ladder Safety Training

Ladder incidents continue to rank among the most common jobsite injuries, and many occur before a worker even reaches the roof. Teaching crews to set a proper 4-to-1 ladder angle, tie off at the landing point, and inspect rungs and rails before climbing prevents most of these accidents. When workers approach ladders with the same seriousness as rooftop fall protection, the entire project becomes safer.

Set Up Protective Guardrail Barriers for Work Zones

Guardrails create a strong layer of passive fall protection on large DMI roof systems. They define clear work areas around skylights, eave lines, roof transitions, or staging zones so crews always know where the safe paths are. They let teams work efficiently without relying solely on personal fall arrest for every step.
