Product Description

Product Description

Galvanization is a superior zinc coating applied to the surface of steel, providing unparalleled protection against rust and corrosion that can last for over 50 years—far outlasting paint. While galvanized steel will eventually succumb to rust, its extended lifespan makes it ideal for creating corrosion-resistant nuts, bolts, and nails. This durable material is also the preferred choice for outdoor pipes when plastic alternatives lack the necessary strength. Additionally, it is widely used in manufacturing bus stop benches, balconies, verandahs, staircases, walkways, and ladders, ensuring both robustness and longevity.
Hot Dipped Galvanized Steel Sheet in Coil (GI)This premium product is created by passing the Full Hard sheet, which has already undergone a thorough acid washing and rolling process, through a zinc pot. This essential step coats the sheet with a protective zinc film, enhancing its durability and resistance to environmental factors.
Renowned for its remarkable corrosion resistance, exceptional paintability, and outstanding workability, our Hot Dipped Galvanized Steel Sheet and Coils leverage the unique properties of zinc. The processes and specifications for these two forms are fundamentally identical, ensuring consistent quality and performance.
