U-shaped steel support has the advantages of high setting force, strong support strength, easy installation, and non-deformation. Therefore, it is often used to manufacture roadway shrinkable metal support for mine roadway, mine roadway secondary support, and mountain tunnel support. Protection and other purposes.
The U-shaped steel bracket produced by Shandong China Coal Group has the following characteristics; U-shaped steel bracket bears great pressure, supports long time, and is easy to install and is not easy to deform. Compared with other rigid brackets, U-shaped steel bracket has the advantages of shrinkability and stable and reliable load-bearing capacity. Adapting to the load and deformation of the soft surrounding rock, the U-shaped steel bracket has a high cross-sectional utilization rate, convenient support and small maintenance, and the U3 steel bracket has a high recovery and reuse rate, reduces the use of pit wood, and has obvious environmental benefits.
