29U steel support is mainly used in mine tunnels, secondary support of mine tunnels, and support and support of mountain tunnels. The use of U-shaped steel support can effectively reduce the occurrence of accidents such as roof fall and sheet gangs, which is safe and reliable, and improves the stability of the mine ventilation system.

Features of 29U steel support
1.29U steel support has the characteristics of high pressure resistance, long support time, easy installation and deformation.
2.29U steel support are more scalable and stable than other rigid brackets. They are suitable for the load and deformation of soft surrounding rocks, high cross-section utilization rate, convenient bracket support, high bracket reuse rate, and reduced use of pits. Environmental protection benefits are very obvious.
3.29U type steel support is safe and reliable to connect, improve the service life of the roadway, reduce the moral maintenance rate of the roadway, and see the occurrence of safety accidents to ensure the safe production of the coal mine.
