Product Description

Product Description

Galvanization, an advanced zinc coating technique, is applied over steel to offer superior rust and corrosion resistance, enduring for 50 years or more. This treatment far outlasts traditional paint. Galvanized steel is essential in manufacturing corrosion-resistant nuts, bolts, and nails. Its strength makes it ideal for outdoor pipes where plastic piping would fail. Additionally, it is the material of choice for bus stop benches, balconies, verandahs, staircases, walkways, and ladders, ensuring long-lasting durability and reliability.
Hot Dipped Galvanized Steel Sheet in Coil (GI)is meticulously produced by passing the Full Hard sheet, which has undergone a comprehensive acid washing and rolling process, through a zinc pot. This method effectively applies a protective zinc film to the surface.
Exhibiting exceptional corrosion resistance, paintability, and workability, this product leverages Zinc's inherent properties. The production processes and specifications for hot dipped galvanized steel sheets and coils are remarkably similar, ensuring consistent quality.
