W steel manufacturers perennial supply

W steel use: W is a new strip mine supporting material, W strip with a thickness of 3-5mm width 180-320mm rolled steel, cold-formed after a W-type, processed and anchor in the middle of the strip W steel bolt hole spacing equal. W steel bolt together with a variety of various combinations of anchor plate bracket, W W steel strip that is scattered by a plurality of anchor banded together to form a whole bearing structure, W steel is widely used in coal mine roadway, work cut in, caverns and other areas of roadway, surrounding rock instability to handle better. W - beam and flat compared to the technical superiority of the strip: 1, W steel band bending section modulus increase 37-fold. 2, the stiffness increased by about 70 times. 3, W - beam hardening during cold rolling, and improve the tensile strength of 12% --15%. W steel for use: At present, domestic mine production company, W strip some mining has reached 500-1000 meters deep, stress, stress and deformation of surrounding rock complex and diverse, a single bolt support has not meet the broken roof, composite roof, roof pressure of the roadway requirements, with anchor bolt and W - beam beam system composed of, can effectively control the roof, but also can be in big fracture roadway, Chamber of Support. Anchor beam system not only solves the problem of roadway can also be applied in other large section of roadway, supporting chambers can also be used in a landslide, embankment, dam reinforcement. Anchor beam systems are generally less suitable for medium-stable rock formations. Roadway supporting the application, saving a lot of steel and wood. It also greatly reduces the labor intensity, improve the labor environment, efficient coal mine production safety to bring significant economic and social benefits. With the improvement of safety awareness of the mining industry, as well as the special requirements of the State of mineral production, coal mine with a professional W Supporting profiles more and more attention, such support is to ensure that an important part of the profile mining production safety.
