As innovator of RUSTY CORRUGATED METAL PRODUCTS, Recla Metals is the paramount specialist in rusted roofing products and accessories. Rusty Corrugated Metal is a specially designed roofing and sheeting product that creates the old rusted tin look, but uses new manufactured steel. Rusty Corrugated Metal (RCM) can be used as a roofing and siding material for residential as well as commercial settings. RCM is very different than Corten. Although any rusty roofing may be referred to as “Corten” or “Weathering Steel”, RCM is a different product. Both Corten and RCM have the same look and lifespan, they differ in price and availability.
