The reason for the corrosion resistance of weather resistant steel plate

Weather resistant steel plate is popular in the construction industry because of its unique orange-brown oxide (or rust) finish. This layer of rust helps resist corrosive elements. But how does weather resistant steel plate form a rust layer?

Weather resistant steel plate does rust. However, it will only rust on the outer layer, and once the initial layer is formed, it will not penetrate into the steel. For weather resistant steel plate, the rust layer acts as a barrier to protect the steel from corrosion. The specific alloying elements in the weather resistant steel plate will produce a stable rust layer that adheres to the base material and is not as porous as typical rust.

Weather resistant steel plate has many advantages, making it an ideal choice for construction:

Preventing further rust and staining

Heat-resistant

Corrosion-resistant

Easy to form

Low-maintenance

Environmentally friendly and recyclable
