About GulfSeam™


Click to Enlarge Gulf Seam

GulfSeam™ is a clip lock metal roofing system. It features a hidden screw design. Clip lock metal roofing allows for maximum design strength. The clips are fully integrated and install without a seamer. The clips attach to the panels. This allows for a safe and strong connection. GulfSeam™ metal roofing is energy efficient and virtually maintenance-free. Making it a great choice for mid to high end homes. Clip lock metal roofing is also widely used in commercial applications.

GulfSeam™ panels feature a bold 1-3/4″ vertical seam. The panel can be roll formed in many widths between 12″-18″. Hidden fasteners aren’t visible on the final product. This makes for an appearance that is smooth and clean. Hidden fasteners combat the forces of nature without direct contact to wind and rain. The clip anchoring system allows for unlimited thermal expansion. MORE >>
