Integral Lock Rib
This intregal lock rib panel system was first developed and produced in Germany and then Austrailia making its way to the United States in the mid-1970’s. Not produced by many manufacturers today, the panel is widely used in the Western U.S and is extensively installed on self-storage facilities. Typically, the panel has rib centers (A) of 8” or 9” with rib heights (B) of 1-5/8” and 2”.
