1219mm Width Regular Spangle Z80 Gi Coils Hot DIP Galvanzied Coil

Advantages of Galvanized Coils

1.Anti-corrosion performance: The galvanized layer forms a protective film of zinc oxide/zinc carbonate through the principle of preferred corrosion by sacrificial anodes, effectively isolating the steel substrate from contact with corrosive media. When the thickness of the hot-dip galvanized coating is ≥45μm, the corrosion rate under salt spray test is ≤1μm/ year, and the corrosion resistance life is 5 to 10 times longer than that of ordinary steel coils.

2.Processing performance: The galvanized coating does not affect the cold bending, stamping and welding performance of the base material, but the die gap (coating thickness +0.02mm) needs to be controlled to avoid zinc coating peeling. The galvanizing process slightly increases the yield strength (about 5-10 mpa) without affecting the low-temperature toughness.

3.Excellent surface quality: The surface of the galvanized coil is smooth and flat, effectively reducing wind resistance and noise, lowering dust accumulation, and facilitating cleaning and maintenance.

4.It has a wide range of application scenarios: it is suitable for buildings (steel structure factories, roof panels), home appliances (refrigerator shells, washing machine inner drums), automobiles (chassis anti-corrosion, exhaust systems), and the energy field (photovoltaic brackets), meeting both anti-corrosion and structural strength requirements.
