25mm A588GrA weathering steel plate

Weathering steel plate originated in North America early, and has a certain history as a building facade material used in North America, Western Europe, Australia, Japan and South Korea in Asia. The main technical support that weathering steel can be used as a facade material is the corrosion resistance of rust steel compared with ordinary weathering steel.

Under the natural climate, the rust steel plate forms a dense layer of about 50-100 microns thick between the rust layer and the substrate by adding weather-resistant alloy elements such as chromium, niobium, molybdenum, nickel, titanium, rare earth and so on. Oxide layer with good metal adhesion (ie rust red).

Due to the existence of this dense oxide film, oxygen and water in the atmosphere are prevented from infiltrating into the steel matrix, slowing down the deep development of corrosion into the steel material, thus greatly improving the atmospheric corrosion resistance and decorative effect of the rusted steel plate material. The research shows that the anti-atmospheric corrosion resistance of the rust steel plate can be 5-8 times higher than that of the ordinary weathering steel due to the different components of the rust steel plate and the different use environments of the steel components. The special dense oxide layer formed on the surface of the rust steel plate has a stable and uniform natural rust red color, which makes it an attractive building exterior wall material and a revolutionary material for a new generation of curtain wall decoration. Excellent value for money and stainless steel.
