Sturdi-Rib

Reduce leakage in your barns, lean-tos, out-buildings, and sheds with Sturdi-Rib.

Sturdi-Rib is a low-profile, full lap pattern, through-fastened panel and is available in 29-gauge, 36" coverage for fast, low-cost applications.

Its 9" rib spacing with additional bell-top rib makes it more rigid than most 9" rib-spaced panels, making it perfect for use on sheds, equipment storage, and other out-buildings with open framing..

Reduce Leaks

Sturdi-Rib features a hidden siphon groove at the underside of the sidelap joint, preventing the capillary action that sucks water in, greatly reducing your chance for leaks.
