Key Features & Benefits
  • Excellent Corrosion Resistance: Zinc coating provides superior electrochemical protection compared to painting and plastic coating, lasting decades without peeling
  • Strong Durability: Acts as both physical barrier and sacrificial anode when coating is damaged
  • Superior Workability: Maintains steel processability with thin, uniform zinc layer
  • Thermal Resistance: Maintains integrity up to 230°C without discoloration
Applications

Widely used in construction industry for roofing materials, wall panels, and structural components due to excellent corrosion resistance and durability.
