W steel strip mining W steel strip, W-shaped steel, mining support steel strip JSD-WX W shaped steel with a new type of mine support and tunnel support material, the product can be used with a variety of bolt jointly organized portfolio bracket bolt through it can root anchor scattered join together to form a whole load-bearing structures, significantly improve the overall effect of the bolt, the incomplete roof strata, to deal with unstable surrounding rock is best. w steel strip is so named because of its cross-section much like the letter "W" w steel tape for Q235. w steel strip is also called the roof strip, slitting raw materials for steel, multiple mill continuous cold bending roller and pressed steel products. w steel strip is a new type of mine support and tunnel support material, with bolt combined together constitute the the Bolting grid, play a rock wall or roadway supporting role. w steel strip is widely used in mine roadway Face Cut, chamber and other areas of the roadway support, unstable surrounding rock better handling. Common width: 180mm, 200mm, 220mm, 250mm, 280mm, 300mm Common thickness: 2.5mm, 2.75mm, 3.0mm commonly aperture: 40mm * 60mm 30mm * 70mm w strip length can be customized according to the actual needs of customers. w steel strip decentralized multi-root anchor banded together to form a monocoque structure, significantly improved the overall effect of bolting the full slate of top better. Reduce support costs, save supporting steel. w the main advantages of the strip: Model Select 1 under different geological conditions and operating environment; 2. bending section modulus increased by 37-fold down section modulus of about 2.75 times the upward section modulus, so installation, adopt top of the Roofbolter up tight; 3. than with other types of steel strip, the W steel tape will not tear easily, and rigidity, increased by about 70 times; the rolled process of hardening to improve the anti- The tensile strength of 12% -15%; 5-section utilization, material saving, low prices. Jining the Gast Mining Equipment Co., Ltd., specializing in the production of W steel strip, in full compliance with national technical standards, the products are mainly exported to the major large coal mines in Shanxi, Shaanxi, Inner Mongolia, Xinjiang, Guizhou, Sichuan, available from stock, complete model. Jining the Gast Mining Equipment Co., Ltd., for many years engaged in the production of mining equipment and R & D, with the strength to prove the quality, welcome new and old friends came to discuss.
