Who Is Butler Manufacturing

Butler Manufacturing is a pioneer in pre-engineered metal buildings, boasting over a century of innovation, craftsmanship, and proven reliability.

Butler Manufacturing has been shaping the metal building industry for over 120 years. The company was founded in 1901 in Kansas City, Missouri, by Emanuel Norquist, Charles Butler, and Newton Butler. In its early years, Butler focused on agricultural products, including galvanized steel stock tanks. That focus soon expanded when a customer requested a steel garage in 1909. Building that garage marked the company's first step into what would become its defining legacy in the world of metal construction.

From that moment, Butler reimagined the construction of steel buildings. In 1939, the company introduced its rigid frame design, establishing a new standard that revolutionized modern construction. Thirty years later, in 1969, Butler launched the MR24 standing seam roof system, which quickly became a trusted solution for long-term roof performance and watertight protection.

Innovation has always been part of Butler's identity. With more than fifty patents to its name, the company has continued to lead the industry in engineering, efficiency, and material technology. Butler buildings are renowned for their strength, flexibility, and lasting value across various commercial, industrial, and agricultural applications.

Growth came steadily through smart expansion, including the acquisition of Howmet Architectural Products in 1984, which broadened their architectural offerings. In 2004, Butler Manufacturing became part of BlueScope Steel Limited, an Australian company with a global presence in steel production and building products.

Today, Butler remains one of the most respected names in pre-engineered construction. Their comprehensive building systems encompass everything from framing and roof panels to fasteners, doors, and windows, offering a seamless approach to design and installation. Whether the project is a warehouse, manufacturing plant, or agricultural facility, Butler Manufacturing consistently sets the standard for quality and innovation in metal building design.

Why Are Non-Penetrating Fall Protection Anchors Crucial for Butler Manufacturing Roofs?

Non-penetrating fall protection anchors protect Butler standing seam roofs by preventing leaks, preserving warranties, and ensuring full OSHA compliance.

Working on Butler Manufacturing roofs requires a careful approach to safety. Standing seam roof systems pose serious challenges for the installers and maintenance workers. The smooth surface and steep slopes create a combination that demands reliable fall protection on every job. Choosing the right anchor system is about more than meeting regulations; it's about protecting the worker and the roof itself.

Standing seam roofs need anchors that attach without puncturing the panels. When an anchor penetrates the metal, it can weaken the panel, create water intrusion points, and void the manufacturer's warranty. Over time, even a small leak can lead to rust, corrosion, or hidden structural damage. That's why Butler roof systems are compatible with seam-mounted anchors that securely attach to the standing seam without altering the roof's design or performance.

By using non-penetrating fall protection anchors, contractors maintain the integrity of Butler's engineered roof systems while ensuring workers remain fully protected. This approach keeps the roof system's watertightness and warranty compliance while promoting long-term durability and adherence to OSHA standards. It's the safest and most responsible way to protect both the people and the investment on every Butler roof.

Butler MR-24 Panels

The Butler MR-24 standing seam metal roof system has unmatched weather performance, strength, and long-term reliability.

The MR-24 system is Butler Manufacturing's signature standing seam metal roof, recognized across the industry for its superior watertight design and proven performance over decades. A key feature of this system is the 360-degree Pittsburgh double-lock seam, a mechanical seam providing exceptional durability and strength. It's the same style of lock used in gasoline tanks and beverage cans, which speaks volumes about its ability to withstand pressure. This design delivers outstanding resistance to wind uplift, far exceeding what traditional crimped or snap-seam systems can handle. See the Roof Anchor Compatibility Chart for Butler Manufacturing MR-24 Standing Seam Panels.

Each MR-24 panel covers 24 inches in width and includes a 2¾-inch rib height. Panels are available in 22 and 24-gauge steel and feature high-strength stainless steel clips. This design allows the panels to expand and contract freely as temperatures change, eliminating stress that can cause warping or binding in less flexible systems. Butler's factory-punched framing ensures perfect panel alignment, preventing the inaccuracies often seen with field-drilled fasteners.

Another hallmark of the MR-24 system is its two-piece clamped splice, which sits over structural members to reinforce the roof and prevent leaks where panels meet. Combined with movable clips, precision factory punching, and engineered splice placement, the MR-24 acts as one continuous surface, protecting the building like a monolithic layer of steel.

The system supports thicker insulation packages, including Butler's ThermaLiner insulation system, improving thermal performance and energy efficiency. It's also available in several cool color finishes, helping reduce heat absorption and energy costs. With a UL Class 90 wind uplift rating and approvals from FM Global, the U.S. Army Corps of Engineers, and Miami-Dade County, the MR-24 has earned its reputation as one of the most durable standing seam roofs in the world.

Ideal applications include manufacturing plants, retail centers, office complexes, truck terminals, and indoor athletic facilities; anywhere strength, longevity, and watertight reliability are essential.

Fall Protection for Butler MR-24 Panels

Non-penetrating fall protection systems protect both workers and the MR-24 roof's watertight design by preserving its structural integrity and manufacturer's warranty.

Because of the MR-24's precision-engineered standing seam, traditional anchors that rely on screws or penetrations are not suitable. The seams must remain fully sealed to maintain the roof's structural and weather performance, which makes non-penetrating anchors the only proper solution for fall protection.

The SSRA1 Standing Seam Roof Anchor provides the foundation of a safe tie-off system for these roofs. It clamps directly to the seam with twelve non-penetrating set screws, creating a certified 5,000-pound anchor point that keeps workers protected while preserving the roof's warranty.
The SSRA2 Adjustable Roof Jack Adapter mounts on top of the SSRA1 anchors, allowing crews to install 10-foot wooden walkboards for stable footing on steep roof sections. Together, these two products give workers a reliable, non-penetrating platform to move safely across the roof.

For larger projects where multiple workers need maximum mobility, the SSRA3 Anchor Plates connect to pairs of SSRA1 anchors to support temporary lifeline systems. When paired with the SSRA 100-foot Horizontal Lifeline Kit, crews can work across long roof runs without constantly relocating anchors. This comprehensive setup provides for fast installation, secure tie-off points, and full OSHA compliance, with zero roof penetrations.

Facilities that require ongoing roof access benefit from a more permanent solution. The Super Anchor 120-foot Standing Seam Horizontal Lifeline Kit is ideal for long-term maintenance operations.

This mechanical seam provides unmatched resistance to wind uplift, foot traffic, and thermal expansion stresses, ensuring long-term stability across a wide range of climates. See the Roof Anchor Compatibility Chart for Butler Manufacturing CMR-24 Standing Seam Panels.

Panels measure 24 inches wide and are available in both 22 and 24-gauge steel, allowing project designers to balance weight and strength requirements. A key structural element of the CMR-24 is its integrated bearing plate, which evenly distributes the load of panels and clips over the framing system. This feature improves load transfer, minimizes stress points, and reinforces the roof's overall integrity.

Energy efficiency is where the CMR-24 truly stands out. The system integrates rigid insulation boards of varying thicknesses to achieve targeted thermal performance goals. A metal liner panel seals and protects the insulation, creating a clean and finished appearance on the interior side of the roof. This design makes the CMR-24 especially appealing for projects where both energy savings and aesthetic presentation matter.

With a 2¾-inch rib height, the CMR-24 maintains the bold architectural profile of the MR-24 while offering lower maintenance and exceptional value. It meets stringent performance benchmarks, including UL Class 90 wind uplift, FM Global approval, and Miami-Dade certification. Available in several cool color finishes, this system helps reduce energy costs while maintaining a strong and secure building envelope.

Safety Tips For Standing Seam Roofs

Equip Workers with High-Quality Safety Gear

No safety program succeeds without dependable equipment. A well-fitted harness, a secure lifeline, and a properly inspected lanyard can make all the difference in the moment that matters most. Workers who trust their gear move with confidence, not hesitation. Keep every piece clean, stored properly, and tagged for inspection. OSHA's 2025 standards place a strong emphasis on proper fit, so take a moment before work begins to ensure that every harness and lanyard is adjusted correctly for each worker.

Develop OSHA-Compliant Safety Plans

Proper safety begins long before anyone steps onto the roof. A detailed plan outlines tie-off procedures, designates rescue points, and clarifies each person's role in ensuring the crew's protection. It's not just paperwork—it's coordination. When an incident happens, crews that follow a well-documented plan don't freeze or argue. They act. Every job should begin with a walkthrough of that plan, ensuring that everyone knows their part in keeping the team protected.

Encourage the Use of Trauma Straps

A harness can stop a fall, but it can't stop circulation loss. That's where trauma straps come in. These compact devices attach to the harness and let a suspended worker take the weight off their legs until help arrives. They're small, inexpensive, and often overlooked, but they can make the difference between a close call and a medical emergency. The best habit to form? Never wear a harness without them.

Use Specialized Anchor Systems for Standing Seam Roofs

Standing seam metal roofs are precision-built, and their safety systems should be too. Anchors that clamp directly to the seams, such as the SSRA1, hold firmly without drilling or damaging the panels. They preserve the roof's warranty while keeping workers secure. Steer clear of any system that involves guessing where clips sit beneath the panels; the risk and potential repair costs simply aren't worth it.

Ensure Proper Footwear for Stability

It's easy to underestimate the value of good boots until you've lost your footing once. Roofing demands balance, grip, and endurance, and the wrong pair of shoes can throw all three out the window. Select footwear with firm soles, ankle support, and traction designed for use on metal surfaces. Stable footing keeps workers focused on the job, rather than fighting gravity with every step.

Set Up Protective Guardrail Barriers for Work Zones

Guardrails don't have a visible, physical boundary around roof edges, skylights, and other open areas, thereby eliminating the risk of accidental missteps. On crowded jobsites, guardrails also help organize work zones, giving crews a clear visual reminder of where safety lines begin. They're simple, effective, and often the unsung heroes of fall retention.

Prioritize Ladder Safety Training

For many roofers, the day's first risk starts before their boots even touch the metal roof. Ladder safety is the foundation of every roofing project. Check each ladder for defects, secure it with a proper base angle using the 4-to-1 rule, and maintain three points of contact when climbing. It's not complicated—but skipping these basics causes more injuries than most realize. A steady climb sets the tone for a safe day's work.

Consult Experts for Curved Metal Panels

Curved metal roofs are as complex as they are beautiful. The shape and slope can change how anchors grip and how fall protection behaves. Before a crew starts work on a curved surface, a certified fall protection expert should inspect it and design a site-specific plan. Their expertise helps avoid costly mistakes, keeps workers secure, and ensures the craftsmanship of the roof remains untouched.

Promote a Culture of Safety

Rules are important, but culture drives behavior. When teams openly discuss risks, share experiences, and support one another, safety becomes second nature. Crews that look out for one another notice hazards more quickly and take fewer risks. The best job sites are those where safety isn't just a requirement but a shared habit that everyone practices every day.

Install Permanent Roof Anchor Systems

Some buildings need regular access for maintenance, inspections, or repairs. In such cases, permanent roof anchors are the most prudent investment. They eliminate the time and risk of setting up temporary anchors, providing immediate and reliable tie-off points whenever someone steps onto the roof. Once installed, they blend into the structure and deliver years of dependable protection. It's the simplest way to make every future visit safer and faster.
