Offices Where Quality Makes the Difference Seam-Lok Premium Standing Seam Roof System. All Corle buildings are manufactured with field-seamed standing seam roof systems, which are UL rated and FM approved.The roofing systems utilize a complete materials color matching system with Kynar 30-Year warranted color finishes.   Galvanized Plated Purlins, Girts and Door Jambs Extend Building Life With Better Rust Protection. Galvanized substructures protect Corle buildings from red rust during and after construction, resulting in better protection, with extends the life of your finished product. Corle galvanized plated materials are tested to withstand over 100 hours os salt spray (many times the corrosion protection of red oxide primer) in accordance with ASTM-117.   I-Beam End Walls Provide Stronger Buildings. The I-Beam has been the basic structural shape of steel since the first use of structural shapes, representing the fundamental strength and durability of steel itself. It is the only type of structural shape used on Corle end wall framing. Unlike cool rolled steel sections that are formed form lighter gages requiring more lateral support, the rigid, hot rolled I-Beam sections provide the strength and stiffness needed to keep Corle end walls true and square, making end farming easier and faster to erect.   Check out the Framing Systems (click here)   Available Colors (click here)
