1. Definition & Manufacturing Process
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).
Key process steps include:
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.
2. Key Features
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.
3. Applications
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.
4. Advantages
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.
