Product Description

Product Description

Galvanization involves applying a robust zinc coating over steel, providing unparalleled protection against rust and corrosion. This process extends the lifespan of the steel, often exceeding 50 years, far outperforming traditional paint. Ideal for crafting corrosion-resistant nuts, bolts, and nails, galvanized steel is also indispensable for outdoor applications where plastic lacks the necessary strength. It is the material of choice for constructing bus stop benches, balconies, verandahs, staircases, walkways, and ladders, ensuring durability and longevity in various settings.
Hot Dipped Galvanized Steel Sheet in Coil (GI)is meticulously produced by passing the Full Hard sheet, which has undergone stringent acid washing and rolling processes, through a zinc pot, thereby applying a resilient zinc film to its surface.
Boasting exceptional corrosion resistance, superior paintability, and outstanding workability due to zinc's unique properties, hot dipped galvanized steel sheet and galvanized steel coil share nearly identical processes and specifications.
1. Standard: JIS G3302, ASTM A653M/A924M, EN10327, and more.
2. Grade: SGCC, DX51D, DX54D, CS type A, Grade 50, and other excellent materials.
