GALVALUME is a sheet steel product having a coating of an aluminum-zinc alloy applied by a continuous hot dipping process. It combines the corrosion resistance, high temperature oxidation resistance and heat reflectivity of aluminum coatings with the formability and galvanic protection of zinc coatings. This datasheet provides information on composition, physical properties, hardness, and tensile properties. It also includes information on corrosion resistance as well as forming, joining, and surface treatment. Filing Code: Al-257. Producer or source: Bethlehem Steel Corporation.
