0.09mm-6.0mm Hot Dipped Galvanized Steel Coil with 5% Al-Zn Coating and Customizable Thickness for Roofing and Construction

A galvanized steel coil is a rolled steel product coated with a protective zinc layer through hot-dip galvanizing (immersing steel in molten zinc) or electro-galvanizing (electrolytic deposition of zinc).

• Base Material: Cold-rolled (smooth surface) or hot-rolled (higher strength) steel strips.
• Coating Types:
  • Pure Zinc Coating: Standard corrosion resistance.
  • Zinc-Iron Alloy Coating: Enhanced weldability and paint adhesion via post-heating treatment.
  • 5% Al-Zn Coating: Superior electrochemical passivation and corrosion resistance compared to traditional zinc coatings.

• Corrosion Resistance: Zinc acts as a sacrificial layer, protecting steel from oxidation and moisture.
• Surface Quality: Available in bright surface finishes for aesthetic applications.
• Formability: Suitable for stamping, bending, and welding.

• Construction: Roofing, purlins, and structural components.
• Automotive: Body panels, chassis parts, and repair materials.
• Household Appliances: Refrigerator shells, washing machine frames.
• Industrial: Pipes, containers, and furniture frameworks.

• Cost-Efficiency: Long service life reduces maintenance costs.
• Environmental Sustainability: Fully recyclable and supports green manufacturing.
• Customization: Available in varied thicknesses (base steel and zinc coating) for diverse industrial needs.
