Galvalume steel sheet is carbon steel sheet coated with aluminum-zinc alloy by a continuously hot-dipped process. The 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 steel substrate when the product is roll-formed, drawn, or bent during fabrication. 

Galvalume has the Applications include pre-engineered metal buildings, industrial roofing and siding, air-conditioning equipment, automotive under-body parts, building panels, electrical boxes, farm equipment and machinery, walk-in coolers, furnace parts, guide rails, heating equipment, home laundry appliances, outdoor signs, playground equipment, small appliances, vending machines, and wall panels.
