What is Building Material Q265GNH Weathering Steel Plate？
Q265GNH weathering steel is a steel with atmospheric corrosion resistance by adding a small amount of alloy elements such as Cu, P, Cr, Ni, etc. to form a protective layer on the metal substrate surface.
Q265GNH brand representation
The grade of steel is composed of "yield strength", "high weathering", or "weathering", the first letter of the Chinese phonetic alphabet "Q", "GNH" or "NH", the lower limit of yield strength and the quality grade (A, B, C, D, E).Weathering steel refers to low alloy structural steel with protective rust layer and atmospheric corrosion resistance, which can be used to manufacture steel structures such as vehicles, bridges, towers, containers, etc. Compared with ordinary carbon steel,

Use of weathering steel
Due to its excellent corrosion resistance, weathering steel has been widely used in steel structures such as buildings, vehicles, bridges, towers, etc. There are three main ways to use weathering steel: bare use, coating use and rust layer stabilization.
1. Exposed use:
The most common use of weathering steel is exposed. Generally, after 3 to 10 years, the rust layer on the surface of weathering steel gradually stabilizes, the corrosion development slows down, and the appearance is beautiful chocolate color.
Because the stabilization process of the rust layer of the weathering steel is affected by the chemical composition of the steel, the use environment, the stagnant water and dust in the structural details, and the mechanical wear and other conditions, if improperly used, the formation conditions of the stable rust layer will be damaged, and the weathering steel will also produce serious corrosion.
2. Application of coating:
In many departments such as buildings, bridges, vehicles, etc., weathering steel, like ordinary steel, is mostly used for coating. Compared with ordinary steel, the coated weathering steel shows excellent corrosion resistance. However, due to the increased use cost and operation process, it is difficult to apply coating to large components generally.
3. Use after stabilization:
At the beginning, a treatment is carried out on the surface of the components to shorten the formation process of the stable rust layer of the weathering steel, which can not only avoid the phenomenon of yellow rust liquid sagging in the initial use of the weathering steel, prevent pollution, but also form a stable rust layer. Although the exposed use is an economic and unique use method of the weathering steel, it takes a long time to complete the stabilization process of the rust layer in the natural environment, Before the formation of stable rust layer, the early rust liquid sagging and scattering often pollute the surrounding environment.
