Product Description

Product Description

Galvanization involves coating steel with a robust layer of zinc, providing long-lasting protection against rust and corrosion that can endure for over 50 years. This makes galvanized steel an ideal choice for manufacturing corrosion-resistant nuts, bolts, and nails. Its strength also makes it perfect for outdoor pipes where plastic is insufficient. Moreover, it is widely used in constructing bus stop benches, balconies, verandahs, staircases, walkways, and ladders, ensuring durability and longevity in various outdoor applications.
Hot Dipped Galvanized Steel Sheet in Coil (GI)is meticulously crafted by passing the Full Hard sheet, which undergoes an acid washing and rolling process, through a zinc pot. This procedure meticulously applies a protective zinc film to the steel surface.
Renowned for its superior corrosion resistance, excellent paintability, and remarkable workability, thanks to the unique properties of zinc. The production process and specifications for hot dipped galvanized steel sheets and coils are fundamentally similar, ensuring consistent quality and performance.
