High-performance weathering steel plate and fire-resistant steel plate can reduce the cost of maintenance and management of steel structure in China, and provide a new Chinese solution to solve the problem of fire and corrosion resistance of steel structure. For example, high voltage power tower;
2. Fire-resistant weathering steel production and installation of a process management is basically the same as the ordinary steel structure with the same design and research methods are also the same as the ordinary steel structure, but we need more test results to verify;
3. High strength weathering steel has been promoted and applied in bridge engineering, so it is necessary to study its design theory and method;
4. The floor load-bearing plate can also use fire-resistant weathering steel plate.
Weathering-resistant steel plate carries on with a good resistance to atmospheric environment corrosion equipment performance, although can be applied to weathering-resistant steel plate preliminary investment enterprise cost is slightly higher than plain carbon steel, but with the plain carbon steel material surface spraying anticorrosive coatings and other methods of research and comparison, the plain carbon steel version of the late management and maintenance costs is weathering-resistant steel of 1.5-2 times. Therefore, weathering steel can reduce environmental pollution, is the key technology of energy saving and emission reduction.
Most of the domestic weathering steel can be used for painting, its free painting and "rust rust" design an initial intention and not be able to get their own different degrees of play. In the harsh use of the environment, weathering steel corrosion layer is difficult to densify, coupled with the appearance of the steel structure in the early use of corrosion is not uniform, therefore, the application of weathering steel environment and surface treatment technology has been plagued by the application of weathering steel.
