- 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
Widely used in construction industry for roofing materials, wall panels, and structural components due to excellent corrosion resistance and durability.
We offer comprehensive value-added processing including bending, welding, decoiling, punching, cutting, moulding, polishing, annealing, and heat treatment.
Each product undergoes rigorous testing including mechanical testing, hardness testing, chemical analysis, PMI testing, micro/macro testing, pitting resistance testing, flaring testing, and intergranular corrosion testing.
