The 2
1/2 " Rib panel can be used to replace conventional 2
1/2" CORRUGATED 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.
