W-shaped steel strip
Product Description
W-shaped steel strip is a common steel product, which is widely used in construction, bridge, machinery manufacturing and other fields. This paper will introduce the basic knowledge, production process, performance characteristics, application field and future development trend of W-shaped steel strip in detail. The W-shaped steel strip is a type of steel shaped like "W", also known as "H-shaped steel strip". Its cross-section shape is "W" shape, the middle is a horizontal waist, both sides are inclined wing, with high strength and stiffness. The commonly used materials of W steel strip are Q235, Q345, Q420, etc., and its standard size is 200mm×200mm, 250mm×250mm, 300mm×300mm, etc., and the length is generally 6 meters, 9 meters, 12 meters, etc.
Product Process
The production process of W-shaped steel strip mainly includes two methods: hot rolling and cold bending.
Hot rolling method: First of all, the raw material billet is preheated to a certain temperature, and then through the rolling, cooling, roll adjustment, cutting and other processes of multi-roller table, the final product is formed. The W-shaped steel strip produced by hot rolling method has the advantages of high strength, stiffness and toughness, but the surface roughness is large, which needs to be processed later.
Cold-bending method: the hot-rolled steel plate is cold-bending, and after many bending, cooling, dressing and other processes, the W-shaped steel strip is finally formed. The W-shaped steel strip produced by cold bending method has high surface flatness and dimensional accuracy, but its strength and stiffness are slightly lower than that of hot rolling method.
Performance Feature
W-shaped steel strip has the following characteristics:
High strength: The section shape of the W-shaped steel strip is a uniform distribution of combined sections, with high strength and stiffness, and can withstand large loads.
Good seismic performance: The cross-section shape of the W-shaped steel strip has good seismic performance and can play an important role in natural disasters such as earthquakes.
Convenient construction: W steel strip has high dimensional accuracy and good surface flatness, which is convenient for on-site construction and assembly.
Good corrosion resistance: The W-shaped steel strip can be treated with different anti-corrosion treatments and has good corrosion resistance.

The anchor beam system is generally suitable for rock formations below medium stability. The application of roadway support in coal mine has greatly saved steel and wood. At the same time, it also greatly reduces the labor intensity of workers, improves the working environment of workers, and brings significant economic and social benefits for efficient and safe production of coal mines.
With the improvement of safety production awareness of industrial and mining enterprises, as well as the special requirements of the state for mineral production, the professional W supporting profiles used in coal mines have also received more and more attention, such supporting profiles are an important part of ensuring mining safety production.
