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.

1. High-performance weather-resistant steel and fire-resistant steel can reduce the maintenance cost of steel structures, and provide a new solution for solving the fire and corrosion problems of exposed unprotected steel structures, such as high-voltage towers.

2. The production and installation process of fire-resistant and weather-resistant steel is basically the same as that of conventional steel, and the design method is also the same as that of ordinary steel structures, but more test verification is required.

3. High-strength weathering steel has been popularized and applied in bridge engineering, and design theory and methods need to be studied.

4. Fire-resistant and weather-resistant steel can also be used in floor decks
