Weather-resistant structural steel is atmospheric corrosion-resistant steel , which belongs to low-alloy high-strength structural steel . According to its main characteristics, it is divided into high-weather-resistant structural steel and weather-resistant steel for welded structures.

Weather-resistant steel is atmospheric corrosion-resistant steel, which is a low-alloy steel series between ordinary steel and stainless steel. Weather-resistant steel is made of ordinary carbon steel with a small amount of corrosion-resistant elements such as copper and nickel. It has the toughness and plasticity of high-quality steel. , Forming, welding and cutting, abrasion, high temperature, anti-fatigue and other characteristics.
