Main Features Of U–Shaped Channel Mining Steel Support

U-shaped channel steel support is a cross-section shaped like the English letter “U” of steel. U-shaped channel steel support produced in various countries of the cross-section shape, geometry and materials are different, the current production of U-shaped steel models are U18, U25, U29, U36 . U18 and U25 belong to lumbar position; U29, U36 are ear localization. U18 due to low carrying capacity, is rarely produced. 
U-shaped channel steel support with high initial strength, support strength, easy installation, not easy to deformation, etc. features, is commonly used in the manufacture of roadway shrinkable metal support for mine roadway, mine roadway secondary support, and mountain tunnel support Protection and other purposes. 
The use of U-shaped channel steel support effectively reduce the roof, the film to help the occurrence of such accidents, safe and reliable, improved mine ventilation system stability. U-shaped steel retractable support is adopted, which solves the problem of tunneling support. 
Characteristics of U – shaped channel steel support 
1.U steel support can be resisted big pressure, long servicing life and high tension resistance, easy to install and uneasy to deformation and so on. 
2.U-shaped steel stent than other rigid frame with a retractable and stable and reliable carrying capacity, adapt to the soft surrounding rock load and deformation. 
3.U section steel support high utilization rate, support back to facilitate the maintenance of small. 
4.U steel frame recycling high reuse rate, reduce the use of pit wood, environmental benefits are obvious.
