Our Forma Loc panel system is a hidden fastener standing seam panel that offers easy installation for roofers and DIY homeowners alike. The panels snap onto each other to hide fasteners beneath, creating a clean and professional appearance to every installation. FormaLoc is available in 12" and 16" coverages with minor ribs or striations to minimize oil canning. FormaLoc works well for both roof or side panel applications. With long clean lines, this panel system provides recognized standing seam performance, while remaining an affordable product for a wide array of projects. Forma Loc should always be installed on solid decking.
