Galvalume is steel, with a coating of aluminum and zinc. The result is a strong, durable metal with proven long term corrosion resistance. The coating is 55% Aluminum and 45% Zinc and is applied to the steel sheet by a continuous hot dipping process. The coating shields the steel from moisture and contaminants while providing protection from scratches and cut edges. The process gives steel the unique combination of strength, long term corrosion resistance, with galvanic protection at cuts and bends in the material. On average, galvalume has roughly nine times the expected life cycle as galvanized steel.
