Deer Park, WA – Knight Wall Systems today announced the company now fabricates its entire range of rain screen attachment systems using ZAM® corrosion-resistant steel, according to company president Doug Knight. Knight is one of the only façade products manufacturers in North America to adopt ZAM®, which is branded the “corrosion protection of the 21st Century.” “Using ZAM®-coated steel increases our rainscreen products’ lifespan nearly tenfold,” Knight said. “Its performance is similar to stainless steel but at a lower cost, and offers enhanced protection to a rainscreen’s vulnerable spots, like rail perforations and fastener connections, or with open joint claddings.”
