Product Description

Product Description

Galvanization involves applying a robust zinc coating to steel, offering an unmatched shield against rust and corrosion, far surpassing the longevity of paint—often lasting for over 50 years. While rust may eventually set in, galvanized steel proves invaluable in numerous applications. From crafting corrosion-resistant nuts, bolts, and nails to providing strength in outdoor pipes where plastic isn't sufficient, galvanized steel is indispensable. You'll also find it enhancing the durability of bus stop benches, balconies, verandahs, staircases, walkways, and ladders.
Hot Dipped Galvanized Steel Sheet in Coil (GI)Our hot dipped galvanized steel sheet in coil (GI) is meticulously produced by passing the Full Hard sheet through a rigorous acid washing and rolling process, followed by immersion in a zinc pot, which coats the surface with a protective zinc film.
This product boasts exceptional corrosion resistance, superior paintability, and outstanding workability, thanks to the inherent properties of zinc. Typically, the manufacturing process and specifications for hot dipped galvanized steel sheets and coils are fundamentally identical.
