25U steel bracket with effective to reduce the roof, sheet occurrence of accidents, safe and reliable, improve the stability of the mine ventilation system and other significant features. Selection of U-shaped steel arch support shrinkable bracket, better solve the problem of excavation support. Widely used in mine roadway, mine roadway secondary support, and the support of the mountain tunnel support. 25U steel stent due to bear the pressure, support for a long time, easy to install is not easy to deformation, and so loved by the majority of mining machinery industry
1,25U steel arch support to withstand the pressure, support for a long time, with easy to install and easy to deformation and so on.
2,25U steel arch support than other rigid stent with a scalable and stable and reliable carrying capacity to adapt to the soft rock of the load and deformation.
3,25U steel bracket cross-section utilization is high, easy support back to support, maintenance of small.
4,25 U steel arch support recovery reuse rate is high, reduce the use of pit wood, environmental benefits are very obvious. The project is safe and reliable, effectively reduce the caving, sheeting and other accidents, improve the stability of the mine ventilation system.
