Weathering steel plate is a steel plate that is resistant to weathering corrosion. Its source is the Corton steel plate in North America. It belongs to the low alloy steel plate series and is a material between ordinary steel and stainless steel. Weathering steel plate is made of ordinary Q235 series carbon steel with some copper and nickel anti-corrosion alloy elements added. Weathering steel plate has unique characteristics such as toughness/plasticity/modeling/laser/corrosion resistance/high temperature resistance. Its weathering corrosion resistance is two to eight times that of ordinary Q235 carbon steel, and its coating corrosion resistance is two to ten times that of ordinary Q235 carbon steel. It has strong rust resistance, which makes the products have super corrosion resistance and prolongs life. It can reduce thickness, save costs and labor, and does not require maintenance.
Why is it corrosion-resistant? The reason is: after adding a small amount of corrosion-resistant elements such as phosphorus, copper, nickel, chromium, etc. to the weather-resistant steel plate, a dense rust layer with strong adhesion is formed between the steel plate and the surface. This rust layer is uniform and stable, naturally rust red, and the rust layer is dense enough to isolate most of the moisture and oxygen, greatly reducing the corrosion rate and extending the service life in the case of bare installation. It is an excellent material for retro landscapes.
