MR-24 Roof System

Every part of the exclusive MR-24® roof system uses only the highest quality materials to assure you of a weathertight standing seam roof that acts like a single steel membrane protecting your building.

A. Roof panels are permanently seamed together with a full 360° "Pittsburgh" double lock seam to keep moisture out.

B. The seaming process uses a heavy-duty, four-stand, electric, portable roll forming machine called the Roof Funner®

C. Roof clips securely attach the roof panels to the supporting structurals by stainless steel tabs

which are roll formed into the panel seam. Stainless steel tabs are more than 50% stronger than other galvanized standing seam tabs.
The clip design allows for 1¼ inches of movement in either direction to accommodate expansion and contraction forces. This permits building up to 500 feet wide without the need for special expansion joints.

D. Every connection is precisely prepunched at the factory - purlins, eaves, end splices, ridges and flashings - to ensure proper alignment when the roof is erected. Proper alignment is critical to allow the finished, seamed together roof to move as it expands and contracts with

temperature change.

E. A uniquely designed prepunched panel endlap features a two piece clamped connection. A bottom reinforcing plate with four stainless steel studs are placed into the prepunched panels. Then a corrosion resistant aluminum top panel strap clamps the panel endlaps together eliminating any attachment to support structurals. This allows the entire roof to move a single steel membrane. The endlaps are also staggered to permit the full 360° "Pittsburgh" double-lock seam through this critical joint.

The MR-24 roof system is available in 22 and 24 gage aluminum/zinc coated steel. The coating is Butler-Cote® 500 FP (a fluoropolymer containing 70% Kynar 500® and Hylar 5000® resin).

The MR-24 roof system includes a complete line of accessories (seamed-in curbs, stainless steel gutters, etc.) designed to fit perfectly with the MR-24 system.

The MR-24 roof system has a U.L. Class 90 wind lift rating.
