Product Description

Product Description

 

Galvanization is the application of a zinc coating over steel, providing extended protection against rust and corrosion-often lasting over 50 years. Unlike paint, which eventually wears away, galvanized steel remains resilient and durable. This makes it an ideal choice for producing corrosion-resistant nuts, bolts, and nails, as well as for outdoor pipes where plastic is insufficient. Additionally, it is commonly used for bus stop benches, balconies, verandahs, staircases, walkways, and ladders.
Hot Dipped Galvanized Steel Sheet in Coil (GI)Our Hot Dipped Galvanized Steel Sheet in Coil is meticulously produced by passing a Full Hard steel sheet, which has undergone both acid washing and rolling processes, through a zinc pot. This process effectively applies a protective zinc film to the surface.
Thanks to the inherent characteristics of zinc, our product boasts superior corrosion resistance, excellent paintability, and outstanding workability. The processes and specifications for both hot-dipped galvanized steel sheets and coils are essentially identical, ensuring consistent quality.
