S355J0WP atmospheric steel
S355J0WP weather resistant steel is weather resistant steel, S355J0WP atmospheric corrosion resistant steel's executive standard: the implementation of the European standard EN10025-5:2004.
S355J0WP weathering metal features: S355J0WP corten sheet has a protective rust layer resistant to atmospheric corrosion, and can be used to manufacture vehicles, bridges, towers, containers and other steel structures.
Principle of S355J0WP weathering plate: After adding phosphorus, copper, chromium, nickel and other trace elements to S355J0WP weathering steel plate, it can make the surface of the steel form a dense and highly adhesive protective film, impede the rust from spreading and developing inwards, protect the substrate below the rust layer and slow down the corrosion rate.
