Product Description

Product Description

 

Galvanization is a protective zinc coating applied over steel, offering unparalleled defense against rust and corrosion that endures far longer than traditional paint-often exceeding 50 years. Its robust durability makes galvanized steel indispensable in creating corrosion-resistant nuts, bolts, and nails. Additionally, it is the material of choice for outdoor pipes when the strength of plastic piping falls short, and finds extensive applications in constructing bus stop benches, balconies, verandahs, staircases, walkways, and ladders.
Hot Dipped Galvanized Steel Sheet in Coil (GI)This premium product is crafted by passing the Full Hard steel sheet, which has undergone both acid washing and rolling processes, through a meticulous zinc pot immersion, ensuring a flawless zinc film is applied uniformly to its surface.
Boasting exceptional corrosion resistance, remarkable paintability, and superior workability, this product leverages the inherent qualities of zinc. The process and specifications of hot dipped galvanized steel sheets and coils are fundamentally consistent, ensuring reliability and performance.
1. Standard: Adherence to top international standards including JIS G3302, ASTM A653M/A924M, EN10327, and more.
2. Grade: Available in various grades such as SGCC, DX51D, DX54D, CS type A, Grade 50, and others to meet diverse industrial needs.
