Product Description

Product Description

Galvanization is a highly effective zinc coating applied to steel, offering superior protection against rust and corrosion for an extended period—often exceeding 50 years. Unlike paint, which eventually succumbs to the elements, galvanized steel remains robust, making it ideal for a myriad of applications. This includes crafting corrosion-resistant nuts, bolts, and nails, as well as outdoor pipes where plastic alternatives lack the necessary strength. Additionally, it is the go-to material for constructing durable bus stop benches, balconies, verandahs, staircases, walkways, and ladders.
Hot Dipped Galvanized Steel Sheet in Coil (GI)This premium product is manufactured by passing a Full Hard sheet, which has been meticulously acid-washed and rolled, through a zinc pot. This process meticulously applies a protective zinc film to the surface, ensuring top-notch quality.
Featuring outstanding corrosion resistance, enhanced paintability, and optimal workability thanks to the natural properties of zinc. The production process and specifications of hot-dipped galvanized steel sheets and coils are fundamentally similar, ensuring consistent quality and performance.
