What are the main uses of weathering steel?

1. High-performance weathering steel and refractory steel can reduce the maintenance costs of steel structures and provide new solutions to solve the fire and anti-corrosion problems of exposed unprotected steel structures, such as high-voltage power 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 tests are needed to verify it.

3. High-strength weathering steel has been widely used in bridge engineering, and design theories and methods need to be studied.

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