Product Description

Product Description

Galvanization involves applying a robust zinc coating over the steel surface. This method offers superior protection against rust and corrosion, enduring far longer than traditional paint—often for over 50 years. However, eventually, rust may still occur. Galvanized steel is a preferred material for manufacturing corrosion-resistant nuts, bolts, and nails. It is also widely used for outdoor piping when plastic alternatives lack sufficient strength, and for a variety of structural applications such as bus stop benches, balconies, verandahs, staircases, walkways, and ladders.
Hot Dipped Galvanized Steel Sheet in Coil (GI)This product is created by passing the Full Hard sheet, which has been subjected to an acid washing and rolling process, through a zinc pot. This procedure effectively applies a zinc film to the surface.
Thanks to the characteristics of zinc, this product boasts excellent corrosion resistance, paintability, and workability. Typically, the process and specifications for hot dipped galvanized steel sheets and coils are largely identical.
