Galvalume is a carbon steel that has been coated with aluminum-zinc alloy (55% aluminum, 45% zinc) after going through a continuous hot-dip process. Galvalume is ideally suited for roofing and siding applications, also including cutters and pipes as well as automotive parts and appliances. It can be painted or used bare and has excellent corrosion resistance and a long-life span. It can also be readily formed and stamped.
