Basic concept of weathering steel plate

After adding phosphorus, copper, chromium, nickel and other trace elements to the weathering steel plate, a protective film with high density and strong adhesion is formed on the surface, which prevents the corrosion from spreading and developing, and maintains the plate under the rust layer to reduce its corrosion rate.

The amorphous spinel hydroxide layer with a thickness of about 50 μm ~ 100 μm in the middle of the rust layer and the plate has a high density and adheres well to the metal composite material of the plate. Due to the existence of this layer of high density hydroxide film, the oxygen and water in the air are prevented from penetrating into the steel plate, the corrosion is reduced, and the development trend to the deep layer of the raw material of the weathering steel plate is further improved professional ability in body corrosion.

Weathering steel plate is a kind of steel system that can be thinned, applied or simply sprayed to prolong the life of products, save time, save energy and reduce emissions, and upgrade. It is also a steel system that can be integrated into the new mechanism, new technology, new technology and new process of today's iron and steel industry, so as to achieve its sustainable development trend and scientific and technological innovation.
