Knight Wall Systems 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.”
Produced in the US by Wheeling-Nisshin Inc., Follansbee, West Virginia, ZAM is a highly corrosion-resistant hot-dip coated sheet product that offers superior performance to galvanized, 55 percent Al-Zn alloy and Zn-5 percent Al alloy coated steel.  
ZAM is now used to fabricate Knight’s entire product range, including its award-winning CI System and HCI System continuous insulation rainscreens, and the adjustable and super-sustainable MFI System mineral fiber rainscreen. ZAM lasts longer in the most severe environments, provides built-in cut edge rust protection, and promotes cost savings through less maintenance.
