The PC™ systems consist of three parts, the pan, a separate seam or batten, and a clip.The seam is snapped over the clips concealing the fastening system. With the batten style, the system is installed with a spacer clip and is snapped in place. The PC™ systems are not structural panels and must be applied to a solid substrate. PC™ panels can be used for tapered and curved installations. Learn about our curved PC™ System.
