High Quality And Customized Color PPGI Steel Coils

Advantages of galvanized coil

1. GI Steel Coils have Good durability, corrosion resistance and longer service life than galvanized steel plates.

2.Strong corrosion resistance: The zinc layer covering the surface of galvanized coils forms a dense protective layer through hot-dip or electroplating processes, isolating the steel from contact with corrosive media. In salt spray tests, when the thickness of the galvanized layer is ≥45μm, the corrosion rate is ≤1μm/ year, and the service life can reach 3 to 5 times that of ordinary steel, especially suitable for damp, acidic and alkaline environments.

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

4.It has a wide range of application scenarios: it is suitable for fields with high requirements for corrosion resistance, such as building steel structures, home appliance manufacturing (such as refrigerator shells), the automotive industry (chassis anti-corrosion parts), and the energy industry (photovoltaic brackets).
