Main application:

U-shaped Arch steel support are mainly used for mine road support and steel structure project.

Withstand high pressure, support long time, easy to install and easy to deformation. Arch steel support lift straight wall semi-arched shed in the Ready Roadway Intersection of applications, and achieved remarkable results. Optional retractable U-shaped steel bracket, solves the problem of tunneling support. U-shaped steel bracket than other rigid support with a scalable and reliable carrying capacity to adapt to the load and deformation of soft rock, cross utilization is high, easy to stand back support small work of maintenance, support recovery reuse rate, reducing the pit wood used, environmental benefits are clear.
