Weather resistant steel plates are divided into high weather resistant steels,such as Q295GNH, Q355GNH, Q265GNH, Q310GNH, and weather resistant steels, such as Q235NH, Q295NH, Q355NH, Q415NH, Q465NH, Q500NH, Q550NH, etc. The application areas of weather resistant steel plates involve landscape gardens, outdoor structures, photovoltaic power generation, environmental protection equipment , railway carriages, bridge manufacturing and many other industries.
1.Weather resistant steel plate for trains: The use of weather resistant steel plate for railway vehicles can reduce serious corrosion of the vehicle in the atmosphere and significantly increase the service life of the vehicle.
2. Container weather resistant steel plate: In the container manufacturing industry, 345MPa-class hot-rolled thin steel plates, with atmospheric corrosion resistance (high weather-resistant steel plates) with Cu, P, Cr, and Ni as the main alloy components are generally used to manufacture outer plates and inner frames. With the development of the container transportation industry, there will be more and more demand for weather resistant steel plate.
3.Outdoor structural steel: Alloy elements are added to the weather resistant steel plate, so it can produce a more uniform and stable oxide layer, also known as patina. The porosity of the oxide layer is lower than that of the traditional rust layer, and the adhesion to the steel substrate is tighter, and the corrosion rate becomes slower than that of ordinary steel.
4.Weather resistant steel plate for bridge: Bridge steel is required to have high strength, toughness to withstand the load and impact of rolling stock, and it must have good fatigue resistance, certain low temperature toughness and atmospheric corrosion resistance. Due to the addition of corrosion-resistant Cu, Ni and other alloying elements to weather resistant steel plate, it has superior atmospheric corrosion resistance compared with ordinary bridge steel.
5.Weather resistant steel plate for landscape and garden: The special dense oxide layer formed on the surface of Weather resistant steel plate has a stable and uniform natural rust red color, which makes it an attractive building landscape material.
