Mining support steel

Braced Steel

Mine supporting steel can support high pressure, has long support time, easy to install, does not easy deformation.

After being set state load, optimized timbering adds support yielding deformation, increases the load-carrying ability and improves the effect of controlling the surrounding rock.
