Product Description

Product Description

Galvanization is the process of applying a protective zinc coating to steel, significantly extending its lifespan by preventing rust and corrosion far more effectively than paint, often for an impressive 50 years or longer. Despite its longevity, eventual wear is inevitable. Galvanized steel is utilized in the creation of corrosion-resistant hardware such as nuts, bolts, and nails. Additionally, it serves as a robust option for outdoor piping when plastic is insufficient in strength. You'll find it in various structural applications including bus stop benches, balconies, verandahs, staircases, walkways, and ladders.
Hot Dipped Galvanized Steel Sheet in Coil (GI)is meticulously produced by passing the Full Hard sheet, which has undergone rigorous acid washing and rolling processes, through a zinc bath. This essential step applies a protective zinc film to the sheet's surface.
This product boasts outstanding corrosion resistance, paintability, and workability, thanks to the unique properties of zinc. The processes and specifications for hot-dipped galvanized steel sheets and coils are generally consistent, ensuring high-quality performance.
1. Standard: Adheres to JIS G3302, ASTM A653M/A924M, EN10327, and other recognized standards.
2. Grade: Available in various grades including SGCC, DX51D, DX54D, CS type A, and Grade50, ensuring it meets diverse application requirements.
