High Quality China Dx51d SGCC Standard Cold Rolled Galvanzied Steel Coils

Advantages of Galvanized Coils

1.Economic benefits: The full life cycle cost of galvanized steel coils is 30-50% lower than that of ordinary steel coils. Although the unit price of materials is about 15-30% higher (for example, Q235 galvanized steel coil is about 4,800 yuan per ton), the cost of anti-corrosion maintenance is significantly saved and the service life is extended by 3-5 times. ‌

2.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. For example, when applied to ventilation ducts, it can ensure the efficiency of air circulation and extend the maintenance cycle.

3.Long service life: In industrial environments, the corrosion resistance period can reach 10 to 20 years, and in Marine environments, it still remains for 5 to 10 years. Compared with ordinary steel coils, the full life cycle cost is reduced by 30-50%.

4.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.
