A coated metal sheet according to the present invention has undercoat and topcoat paint films formed on the surface of a metal substrate such as a phosphated steel sheet,chromated steel sheet,stainless steel sheet,galvanized steel sheet or aluminum sheet.The undercoat film isGalvalume &Plus/Galvanized Plus (Acrylic coated steel WHEELING-NIPPON STEEL offers two enhanced products Galvalume &PLUS and Galvanized PLUS.Both substrates are coated with a thin,clear acrylic (chromated or RoHS compliant) which not only creates a corrosion resistant sheet,but also eliminates any need for oil during rollforming.This acrylic coating also provides resistance to finger printing,hand printing,foot printing and smudging Some results are removed in response to a notice of local law requirement.For more information,please see here.12345Next
