Product Description

Product Description

Galvanization is a sophisticated process where a zinc coating is meticulously applied over steel. This robust zinc layer provides unparalleled protection against rust and corrosion, enduring far beyond traditional paint with a lifespan that can exceed 50 years. Even though eventual brown rot may occur, galvanized steel remains a preferred choice for its longevity. Ideal for manufacturing corrosion-resistant nuts, bolts, and nails, this versatile material is also employed for outdoor pipes where plastic lacks strength. Its utility extends to public infrastructure, including bus stop benches, balconies, verandas, staircases, walkways, and ladders, ensuring durability and resilience.
Hot Dipped Galvanized Steel Sheet in Coil (GI)This premium product is crafted by passing the full hard sheet, which has undergone an intensive acid washing and rolling process, through a zinc pot. This procedure results in a seamless application of a zinc film to the surface, offering unmatched protection.
Our galvanized steel coil boasts exceptional attributes, including superior corrosion resistance, remarkable paintability, and outstanding workability, all thanks to the inherent qualities of zinc. The hot-dipped galvanized steel sheet and coil processes share similar specifications, ensuring consistency and reliability.
