Zinc Coating: Z40 - Z275

• Superior Corrosion Resistance: Zinc coating provides electrochemical protection and physical barrier, lasting decades without peeling
• Enhanced Durability: Sacrificial anode action protects steel even when coating is scratched
• Excellent Workability: Maintains steel processability with uniform zinc layer that doesn't affect forming operations
• Thermal Resistance: Maintains integrity up to 230°C without discoloration
• Strong Adhesion: Iron-zinc alloy layer enhances strength and improves welding and painting performance
