W-shaped Strap Steel Strip W-shape Steel Tape

In the production mines of various domestic group companies, some have a mining depth of over 500-1000 meters, and the stress, surrounding rock stress, and deformation are complex and diverse. A single anchor rod support can no longer meet the requirements of fractured roof, composite roof, and roadway support with high roof pressure. The anchor beam system composed of anchor rods and W-shaped steel strips can effectively control the roof, and can also be applied to support tunnels and chambers with large fractures. The anchor beam system not only solves the problem of tunnel support, but can also be applied to support other tunnels and chambers with large cross-sections, as well as to reinforce landslides, embankments, and dams. The anchor beam system is generally suitable for rock layers below medium stability. The application of coal mine roadway support has greatly saved steel and wood. At the same time, it has significantly reduced the labor intensity of workers, improved the working environment for workers, and brought significant economic and social benefits to the efficient and safe production of coal mines. With the increasing awareness of safety production in industrial and mining enterprises, as well as the special requirements of the country for mineral production, professional W-shaped support profiles for coal mines are also receiving increasing attention. This type of support profile is an important part of ensuring mining safety production.

Technical advantages of W-shaped steel strip compared to flat steel strip:
1. The bending section modulus of W-shaped steel strip is increased by 37 times.
2. The stiffness has increased by about 70 times.
3. The hardening effect during the cold rolling process of W-shaped steel strip increases the tensile strength by 12% -15%.
