U-shaped steel support can be said to be the most important support profile in coal mine, is the key to roadway support. The U section steel bracket laid in advance, the coal seam may have aging, loose possible, U section steel frame has the ability to shrink, can play a supporting role and the role of the replacement of the old and new!
U-shaped steel support is coal mine supporting , high tensile strength, compressive strength, good toughness properties at the same time, support, support strength, can be used many times, is widely applied in manufacturing roadway yielding metal stents, as mine laneway secondary support, as well as in roadway supported by bolting and other purposes, especially in deep roadway and complex soft coal seam roadway.
U-shaped steel support is high section utilization rate , the support support is easy to support and return, the maintenance quantity is small, the support recycling reuse rate is high, reduces the use of pit wood, the environmental protection benefit is very obvious. The main raw materials are U section steel, U section steel needs to be cut after cold forming, and then connected with U section steel clip cable.
