Hot-rolled coil is a commonly used steel product in the industry. It has a relatively wide variety of products and a wide range of uses. steel plates S690QL, Hot-rolled coils are widely used in related industries such as petrochemical equipment, automobiles and bridges. Hot-rolled coils are also used in machinery industries such as ships and automobiles because of their good toughness and relatively high strength.

When phosphorus, copper, chromium, nickel and other trace elements are added to the weathering steel sheet, a dense and strong adhesion protective film will be formed on the steel surface, which will hinder the corrosion from spreading and developing inside, and protect the substrate under the rust layer, so as to slow down the corrosion rate. That is why the weathering steel sheet, steel plates S690QL has good atmosphere corrosion resistance.
