Who Is Butler Manufacturing?

Butler Manufacturing is a pioneer in the metal building industry with a legacy stretching back to 1901. Founded in Kansas City, Missouri, by Emanuel Norquist, Charles Butler, and Newton Butler, the company initially focused on agricultural products such as galvanized steel stock tanks. However, the turning point came in 1909 when the need for a steel garage led to the creation of their first metal building. This pivotal moment marked Butler's entry into metal building construction. In this sector, they would go on to revolutionize design and engineering.

Through the decades, Butler Manufacturing introduced groundbreaking innovations like the rigid frame building design in 1939, which redefined metal building construction, and the MR-24 standing seam metal roof system in 1969, one of their flagship offerings. The company holds over 50 patents, underscoring its role as a trailblazer in metal building design. Their products are known for their durability, efficiency, and versatility across commercial, industrial, and agricultural sectors.

Butler's growth continued with strategic acquisitions, including the 1984 purchase of Howmet Architectural Products, which expanded its architectural product offerings. Today, Butler Manufacturing operates under BlueScope Steel Limited, an Australian company that acquired them in 2004. Butler remains a leader in pre-engineered metal buildings, known for their comprehensive building systems, including frames, walls, roofs, fasteners, doors, and windows. Whether it's a commercial warehouse or an agricultural facility, Butler Manufacturing has maintained its position as a trusted partner in building design and construction.

Why is Fall Protection Crucial for Butler Manufacturing Roofs?

Working on Butler Manufacturing roofs, especially with their well-known standing seam systems like the MR-24, requires careful consideration of fall protection. Metal roofing projects inherently carry significant risks due to the smooth surfaces, sloped angles, and height of the buildings. Therefore, selecting the proper fall protection solution is essential to ensure worker safety while maintaining the roof's structural integrity.

Standing seam roofs, in particular, require specialized fall protection anchors that do not penetrate the panels. Systems that pierce the roof can compromise the panel's integrity, lead to leaks, and even void manufacturer warranties. Researching and choosing compatible fall protection systems that clamp onto the seams without affecting the roof's structure is crucial. Ensuring the fall protection anchor system adheres to these requirements keeps the roof intact while safeguarding workers.

By using non-penetrating fall protection systems, contractors can uphold Butler's high standards for roofing products, ensuring long-term durability while maintaining compliance with safety regulations.

Butler MR-24 Panels

The MR-24 is a premium standing seam metal roof system known for its superior weathertight performance and long-term durability. A vital feature of the MR-24 is its double-locked seam design, creating a 360-degree Pittsburgh double-lock seam that ensures exceptional seam integrity. This seam is similar to those used in gasoline tanks and beverage cans, providing unparalleled resistance to wind uplift and stresses from roof traffic, outperforming traditional crimped or snapped seams that may fail under such conditions. See the Roof Anchor Compatibility Chart for Butler Manufacturing MR-24 Standing Seam Panels.

The MR-24 panels cover 24 inches in width and feature a 2¾" rib height. Available in 22 and 24-gauge, these panels incorporate high-strength stainless steel roof clips in their side laps. The clips glide along a triangular bar, allowing the panels to expand and contract freely with temperature changes. Unlike systems that restrict thermal movement and potentially cause damage, the MR-24 allows unrestricted expansion without binding.

Butler ensures precise alignment of each panel with their factory-punched structural framing, which includes pre-located holes for proper clip and panel placement. This approach guarantees the highest levels of weathertight integrity, as field-drilled screws often fail to maintain the same level of precision. Additionally, the MR-24 system uses a two-piece clamped splice design positioned over structural members, reinforcing the roof's durability and preventing leaks from adjacent splices.

With its robust seam, free-moving clip system, precise factory alignment, and reinforced splice design, the Butler MR-24 stands out for its superior weather tightness, durability, and wind resistance, making it a leading choice in standing seam metal roof systems.
