Product Description

Product Description

 

Galvanization involves applying a protective zinc coating over steel to significantly extend its lifespan by preventing rust and corrosion. Unlike paint, which can deteriorate quickly, galvanization can protect steel for over 50 years, ensuring durability even in the harshest conditions. This makes galvanized steel ideal for producing corrosion-resistant nuts, bolts, and nails, and it is extensively used in various structural applications such as outdoor pipes, bus stop benches, balconies, verandahs, staircases, walkways, and ladders.
Hot Dipped Galvanized Steel Sheet in Coil (GI)Our Hot Dipped Galvanized Steel Sheet is meticulously crafted by passing the Full Hard sheet through an advanced acid washing and rolling process, followed by immersion in a zinc pot. This thorough procedure ensures a robust zinc film coats the surface, enhancing its protection.
Thanks to the inherent properties of zinc, our galvanized steel sheet boasts unparalleled corrosion resistance, excellent paint adhesion, and superior workability. The processing and specifications of hot dipped galvanized steel sheet and galvanized steel coil are fundamentally identical, ensuring consistent quality.
1. Standard: JIS G3302, ASTM A653M/A924M, EN10327, and other industry-leading standards.
2. Grade: SGCC, DX51D, DX54D, CS type A, Grade 50, and additional high-performance grades.
