Hot-dip Galvanized Steel Coil
Galvanized steel is an essential material in contemporary building and production, recognized for its excellent resistance to corrosion. S280GD galvanized steel, in particular, stands out as a versatile material, offering a balance of strength and durability.
Hot Dipped Galvanized Steel Sheet in Coil (GI) is produced by passing the Full Hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. It has excellent corrosion resistance, paintability, and workability due to Zinc's characteristics. Usually, hot-dipped galvanized steel sheet and galvanized steel coil process and specifications are basically the same.
At GNEE STEEL, we provide high-quality S280GD galvanized steel coils and sheets to meet the demanding requirements of construction frameworks, automotive components, and household appliances.

Surface Treatment
Spangle is formed during the hot-dip galvanizing process. The size, brightness, and surface of spangles mainly depend on the composition of zinc layer and the cooling method. According to the size, it includes small spangles, regular spangles, big spangles, and free spangles. They look different, but the spangles almost will not influence the quality of galvanized steel. You can choose according to your preference and purpose.
