Galvalume Steel Coil nominal coating composition is 55% aluminum and 45% zinc. A small but important addition of silicon is included in the coating alloy. It is added not to enhance the corrosion performance, but to provide good coating adhesion to the galvalume steel substrate when the product is roll-formed, drawn, or bent during fabrication.
