SPCC Sheet Zinc Coating Steel Sheet Coil
ASTM 0.5mm Hot-DIP Galvanized Steel Coil
Galvanized coil is manufactured through a continuous hot-dip galvanizing process where steel plate is immersed in molten zinc to form a protective zinc layer. This process combines the structural strength of steel with the superior corrosion resistance of zinc.

Key Advantages
- Ready stock for faster delivery time
- Available in all sizes with customization options
- Consistently high quality standards
Surface Finish Types
Smooth Galvanized Coil
- Smooth surface without texture patterns
- Uniform zinc coating distribution
- Typically uses "no zinc flower" process with rapid cooling
- Wide zinc layer thickness range (40-275g/m² per GB/T 2518-2019 standard)
- Stable corrosion resistance performance
Zinc Flower Coil
- Visible crystalline patterns (zinc flowers) on surface
- Formed through slow cooling after galvanization process
- Zinc flower size classification (large, small zinc flowers)
- High aesthetic appeal
- Typically slightly thinner zinc layer (60-180g/m²)
