High Style and
High Performance 


CORMAX is the classic corrugated panel, offering strength and durability as well as architectural, industrial farmhouse style. The 3/4-inch rib height makes this low-profile metal panel system both useful and beautiful. Requested by designers for interior detail applications like wall paneling and wainscoting, CORMAX can be installed vertically or horizontally for a different look. Use it as a traditional exterior wall and roof panel and you will never be disappointed.
