2 1/2" Rib Panels

The 2 1/2 " Rib panel can be used to replace conventional 2 1/2" CORRUGATED siding panels while at the same time, allowing for vastly improved carrying capabilities as well as giving more of the appearance of a building panel. This shape too can roughly approximate in 28 GA the load carrying capability of 2 1/2" CORRUGATED in 24 GA.
