- Product Description and Uses
Product Description
Hot-rolled galvanized steel coils are produced by hot-dip coating of raw hot-rolled steel coils with a zinc layer. After chromate coating treatment, the steel is prevented from direct contact with air and water, thus preventing rust. When the zinc layer is scratched and the steel is exposed, the surrounding zinc dissolves to protect the steel from rusting. Therefore, the zinc coating and sacrificial protection of hot-rolled galvanized steel coils result in a longer service life than ordinary hot-rolled or cold-rolled steel products.
