What are the main advantages of weather resistant steel plates?

April 20, 2024

Weathering steel refers to the addition of a small amount of alloying elements such as copper, chromium, nickel, so that it has good corrosion resistance in the atmosphere of low-alloy high-strength steel weathering steel atmospheric corrosion resistance to ordinary carbon steel is 2 to 8 times, and the longer the use of time, the more prominent the corrosion resistance. In addition to good weather resistance, weathering steel also has excellent mechanical, welding and other performance.
Compared with surface spraying anticorrosive paint and other methods, weathering steel has low maintenance cost, reduced environmental pollution, and good economic benefits in the whole life cycle of the building. At present, it has been widely used in railway vehicles, Bridges and containers, and its application in construction engineering is still in its infancy.

After the installation of the weatherproof steel plate, the following problems should be noted

1. Pay attention to the filling height during design
2. Prevent in areas where water is standing
3. After the completion of the ground cement construction, remove the cement contaminated on the weathering steel in time.
4. Arrange cleaning workers to wash the rusty surface after rain.
5. No graffiti on it
6. After the completion of the whole, clean the surface to remove the fallen cement, ash, debris, etc.
Do the above points, the landscape will be greatly improved
Major advantage
Weathering steel is made of ordinary carbon steel with a small amount of copper, nickel and other corrosion resistant elements, with good strength, plastic extension, molding, welding and cutting, abrasion, high temperature, fatigue and other characteristics; The weather resistance is 2 to 8 times that of ordinary carbon steel, and the coating property is 1.5 to 10 times that of ordinary carbon steel, which can be used thinly, exposed or simplified. The steel has the characteristics of rust resistance, corrosion resistance and prolonging life of the component, thinning and reducing consumption, saving labor and energy, benefiting the component manufacturers and users.
Main feature

It refers to the low alloy structural steel with protective rust layer and resistance to atmospheric corrosion, which can be used in the manufacture of steel structures such as vehicles, Bridges, towers and containers. Compared with ordinary carbon steel, weathering steel has better corrosion resistance in the atmosphere. Compared with stainless steel, weathering steel has only trace alloying elements, such as phosphorus, copper, chromium, nickel, molybdenum, niobium, vanadium, titanium, etc., and the total alloying element accounts for only a few percent, unlike stainless steel, which reaches ten percent, so the price is relatively low.
