After adding trace elements such as phosphorus, copper, chromium and nickel into GB/T 4171 Q295NH weathering steel plates, a protective film with dense and strong adhesion is formed on the surface of Q295NH steel, which prevents the rust from spreading and developing, and protects the underlying matrix of rust layer to slow down its corrosion rate, which greatly improve the corrosion
