This Aluminum-Zinc Coated Steel Coil (Galvalume Steel Coil) is manufactured using an advanced hot-dip galvalume process, which uniformly covers the steel surface with an aluminum-zinc alloy to form a dense protective layer. With aluminum accounting for 55% of the alloy composition, the product offers excellent corrosion resistance and weatherability.

Using the hot-dip galvalume process, the coating contains 55% aluminum, forming a dense anti-corrosion barrier. Its corrosion resistance is 2-6 times that of traditional galvanized steel, withstanding harsh environments like acid rain and salt spray. It combines high strength and ductility for excellent formability, adapting to complex shaping needs. With a smooth, clean surface, it supports subsequent painting or laminating. Compliant with ASTM international standards and ISO-certified, it’s widely used in construction roofing, industrial steel structures, automotive parts, etc., offering a reliable solution for high-durability scenarios with a service life of over 50 years.

Exceptional Corrosion Resistance

  • The coating contains a 55% aluminum + 43.4% zinc + 1.6% silicon alloy, forming a dense oxide film. Its anti-corrosion capability is 2-6 times that of traditional galvanized steel, resisting acid rain, salt spray, and industrial atmospheric erosion.

Superior Weatherability and Durability

  • Withstands high temperatures (up to 300℃) and UV radiation, offering strong anti-aging performance. Service life exceeds 50 years, ideal for outdoor high-corrosion environments.

High Strength and Processing Flexibility

  • Combines high tensile strength with excellent ductility, enabling cold bending, stamping, and roll forming to meet diverse processing needs for roof tiles, wall panels, and complex components.
