Which are mounted directly onto a heavy duty, powder-coated structural steel frame offering great versatility for this product to be used in a array of different applications. The Resinwood slats are made from 100% recycled plastic lumber that will not rot, warp or corrode with UV stabilization that provides for maximum fade resistance after years of use.
