Weather-resistant structural steel is atmospheric corrosion-resistant steel, which belongs to low-alloy high-strength structural steel. According to its main characteristics, it is divided into high-weather-resistant structural steel and weather-resistant steel for welded structures. The classification is as follows:
A high weathering steel
High weather resistance structural steel is to add a small amount of copper, phosphorus, chromium and nickel elements to the steel to form a protective layer on the surface of the metal collective to improve the atmospheric corrosion resistance of the steel, and a small amount of molybdenum, niobium, Vanadium, titanium, zirconium and other elements are used to refine the grains, improve the mechanical properties of the steel, improve the strength and toughness of the steel, reduce the brittle transition temperature, and make it have better resistance to brittle fracture. [1]
Weathering steel for two welded structures
The elements added to the steel, except for phosphorus, are basically the same as those of the high weather resistance structural steel, and their functions are also the same, and improve the welding performance.

The steel plate is a flat steel that is cast with molten steel and pressed after cooling.
The Steel Sheet is flat, rectangular and can be directly rolled or cut from wide steel strips.
The steel plates is divided according to the thickness, the thin steel plate is less than 4 mm (the thinnest is 0.2 mm), the medium-thick steel plate is 4-60 mm, and the extra-thick steel plate is 60-115 mm.
Steel sheets are divided into hot rolling plate and cold rolling plate according to rolling.
1. Hot Rolled Steel Plate
Hot rolling processing methods include hot rolling, forging, extrusion and other methods.
2. Cold Rolled Steel Plate
Cold rolling processing methods include cold rolling, cold drawing and cold drawing, cold bending, cold extrusion and other methods.
The cold rolling method is to continue processing the hot rolled steel below the recrystallization temperature to make it cold rolled steel. Using cold rolling processing method can improve the mechanical properties of steel, and obtain products with high dimensional accuracy and certain smoothness.
Weathering steel is used in high piezoelectric tower Weathering steel has been used in bridge
because of its unique corrosion resistance. engineering.
Weathering steel is applied to home decoration. Weathering steel used in large outdoor sculpture steel.
For example, the Luxembourg grand national
pavilion at the 2010 world expo in Shanghai.
