This is the Quadrib panel

The Quadrib^TM panel is a profile that bridges the gap between old and new. It has 4 major ribs that are reminiscent of an older style but the sharp and clean lines bring it back to the modern day. Small bends in-between the major ribs provide more stability while also eliminating oil canning, a common problem with other modern styles like standing seam. Available in both textured and smooth colours.
