Who Is True Metal Supply?
True Metal Supply is the premier source for residential and commercial metal roofing in Knoxville, Tennessee. Founded in 2023 by industry veterans Adam Clark and Mason Burchette, the company was built to bridge the gap between premium material quality and contractor-speed efficiency for the East Tennessee market. Operating from a state-of-the-art 14,000-square-foot manufacturing facility in Knoxville, they utilize advanced CIDAN brakes and roll-forming technology to deliver American-made DuraLock and TrueLock panels with unmatched precision and speed.
Why Non-Penetrating Fall Protection is Critical for True Metal Supply Roofs
Preserving the weather-tight performance of a True Metal Supply roof requires safety hardware that respects the panel design and thermal expansion requirements. Because True Metal Supply standing-seam roofs utilize concealed fasteners, traditional penetrating anchors are unsuitable. Standard anchors that puncture the metal compromise the weatherproof seal, leading to leaks, corrosion, and structural damage. Moreover, such penetrations directly violate manufacturer specifications and void the transferable lifetime warranty. To maintain a watertight seal, contractors must use specialized, non-penetrating anchors. To ensure a 100 percent tie-off without voiding warranties, we recommend the modular SSRA system.
The following products provide a complete safety solution for True Metal Supply profiles:
- SSRA1 Seam Anchor: The foundational component. This patented, universal-fit anchor fits approximately 95% of today's standing-seam profiles, providing a certified 5,000-lb tie-off for non-curved 22-gauge and 24-gauge steel panels.
- SSRA2 Adjustable Roof Jack Adapters: Mount directly to the anchors to hold 10-foot wooden walk-boards, providing stable footing on steep slopes.
- SSRA3 Anchor Plates: High-strength spanner plates that connect two SSRA1 anchors into a single assembly to serve as structural endpoints for horizontal lifelines.
- 100-foot SSRA Horizontal Lifeline Kit: Allows two workers to move the entire length of the roof field while remaining 100 percent tied off on short-term projects.
- 120-foot Super Anchor Permanent HLL: A reliable, long-term maintenance solution using non-penetrating 5-inch riser posts that protect the roof's weather-tight seal.
- Ridge Pro Steep Assist: The essential First-Man-Up tool for pitches between 6:12 and 12:12, providing immediate tie-off before the worker leaves the ladder.
Keep in mind that OSHA and ANSI standards limit horizontal lifeline systems to a maximum pitch of 4:12. OSHA recognizes that workers can lose their footing and slide on steeper roofs, leading to dangerous falls, which is not suitable for horizontal lifeline setups.
Proper Attachment: Set-Screws and Torque Requirements
To ensure certified holding power while protecting the True Metal Supply steel substrate, installers must select the appropriate fastener and torque setting based on the panel gauge:
- Cupped-Tip Stainless Steel Set Screws: Use these exclusively on 22-gauge steel panels and torque to 90 inch-pounds using a calibrated torque wrench.
- Nylon-Tipped Set Screws: These are the most effective for locking onto 24-gauge steel. Torque these fasteners to 180-200 inch-pounds.
- Maintenance: Treat nylon tips as consumables. Replace these tips every 3 to 5 uses to maintain maximum grip strength and ensure compliance with safety standards.
CRITICAL WARNING: NO IMPACT GUNS
Warning: Always use a calibrated torque wrench for final installation. Never use an impact gun to install set-screws. Impact guns can quickly over-tighten the screws, resulting in permanent damage to the standing seam panel or the anchor itself. This error compromises the anchor's certified holding power and voids the hardware warranty.
TrueLock 175 Snaplock Panels (SSRA Compatible — 24-gauge Steel)

The TrueLock 175 features a bold 1.75-inch rib height and a 14-inch panel width. This clip-lock standing seam system is rated for slopes as low as 1:12 on open framing or 1/2:12 on solid decking. It is manufactured in 24- and 26-gauge steel with elite Fluropon PVDF and WeatherXL SMP finishes. See the Roof Anchor Compatibility Chart for True Metal Supply 24 Gauge TrueLock 175 Snaplock Standing Seam Panels.
Fall Protection for TrueLock 175 Panels
- For 24-gauge steel substrates, the SSRA1 Seam Anchor, SSRA2 Adjustable Roof Jack Adapter, and SSRA3 Anchor Plate provide a complete non-penetrating safety solution.
- The 100-foot SSRA Temporary HLL Kit and 120-foot Super Anchor Permanent HLL Kit allow for safe lateral movement across the 1.75-inch structural ribs.
- For 26-gauge steel versions where clamping is not recommended, The Ridge Pro Steep Assist is the required solution for pitches between 6:12 and 12:12.
DuraLock 100 Nailstrip Panels (Ridge Pro Only)

DuraLock 100 features a 1-inch rib height and a 16-inch panel width, providing a sleek, minimalist aesthetic. This nailstrip system is crafted from 24- and 26-gauge steel and requires a minimum slope of 3:12. See the Roof Anchor Compatibility Chart for True Metal Supply DuraLock 100 Nailstrip Standing Seam Panels.
Fall Protection for DuraLock 100 Panels
- Nailstrip profiles utilize an integrated fastener flange that is not designed for SSRA1 clamping loads.
- Ridge Pro Recommendation: The Ridge Pro Steep Assist is the required non-penetrating solution for slopes between 6:12 and 12:12.
- The system hooks securely over the roof ridge, establishing an OSHA-compliant anchor point that preserves the weather-tight integrity and manufacturer's warranty.
DuraLock 150 Nailstrip Panels (Ridge Pro Only)

Building on the 100 series, the DuraLock 150 features a taller 1.5-inch rib height and a 14.75-inch panel width. These energy-efficient panels can reduce cooling costs by 15-25% and are available in 24- and 26-gauge steel. See the Roof Anchor Compatibility Chart for True Metal Supply DuraLock 150 Nailstrip Standing Seam Panels.
Fall Protection for DuraLock 150 Panels
- Like the 100 series, the integrated fastener flange of the 150 series is incompatible with seam-mounted hardware.
- Ridge Pro Recommendation: The Ridge Pro Steep Assist provides the best ridge-mounted protection for pitches between 6:12 and 12:12.
- This strategy ensures a 100 percent tie-off while protecting the architectural ribs from the crushing forces of traditional clamps.

Compliance Tested Anchors vs. Cheap Imports: The Risk of Generic Hardware
A True Metal Supply system is a precision-engineered asset; your fall protection hardware should match the quality of a premier roof system. Opting for unverified, generic, or imported "look-alike" anchors introduces a dangerous and high-stakes variable into your project. Modern safety inspections now prioritize verifying domestic engineering data and serialized documentation. Operating without an ironclad paper trail of compliance with OSHA 1926.502 and ANSI standards is a significant liability that leads to regulatory shutdowns and severe legal consequences.
Secure your crew with American-engineered SSRA hardware—machined from solid 6061-T6 aluminum and validated by traceable laboratory results. Review our full independent laboratory test reports to ensure your project meets the highest standards of structural integrity.

10 Pro Safety Tips for True Metal Supply Metal Roof Projects
- Develop Site-Specific Safety Plans: Never step onto a job site without a written plan outlining fall protection strategies and emergency rescue protocols tailored to the specific True Metal roof geometry.
- Strictly Enforce the 4-to-1 Ladder Rule: For every 4 feet of height, pull the ladder base out by 1 foot. Secure the ladder to a seam-mounted anchor to prevent "kick-outs."
- Use Specialized Non-Penetrating Anchors: Protect the building owner's investment by using only non-penetrating, clamp-on anchor systems like the SSRA1 and Ridge Pro.
- Equip Every Harness with Trauma Relief Straps: Suspension trauma can become life-threatening in as little as five minutes. Pre-install relief straps on every harness to prevent blood pooling while awaiting rescue.
- Mandate High-Traction Footwear: Metal roofs are notoriously slick. Ensure every crew member wears boots designed specifically for metal roofing traction to move safely across TrueLock 175 or DuraLock panels.
- Factor "Dynamic Sag" into Total Fall Clearance: Account for the physical stretch of horizontal lifelines during a fall. Always add a 2-to-3-foot safety margin to your Total Fall Clearance (TFC) calculation.
- Deploy Leading Edge (LE) Rated SRLs: standing-seam roof panels feature sharp vertical ribs that can shear through standard ropes. Always equip your crew with Leading Edge (LE) rated equipment.
- Install Permanent systems for Frequent Access: For properties requiring regular maintenance, install a permanent horizontal lifeline system using non-penetrating riser posts and the 120-foot Super Anchor Kit.
- Define Work Zones with Guardrail Barriers: On expansive or low-slope roofs, use guardrails or warning lines to reduce edge-related risks and allow workers to focus on the task at hand.
- Secure the Ladder-to-Peak Transition: The most dangerous moment is the transition from the ladder to the slick metal surface. Extend your ladder 3 feet above the eave and use a stabilizer.
