Concealed Fastener Panels
A weathertight & maintenance-free system
Also called “standing seam,” these systems have no exposed screws, making them the most weathertight and maintenance-free systems. Standing seam is a good choice for commercial and high-end residential projects but require higher-skilled craftsmen and more labor costs for installation.

This 1″ snap-lock system is a great option for many residential and light commercial applications. A contractors’ favorite and one of our best-selling panels.
GulfSeam™
A step up from a nail-strip system but still a snap-lock, this bold 1¾” profile delivers high-end standing seam performance without a mechanical seamer.
