High Torsion GFRP Rock bolt
Compared with steel rock bolt, the low torque is the major cause of limit GFRP rock bolt to used widely,our company developed the high torsion of GFRP rockbolt by improving the structure and optimizing material structure, overcome the shortcomings of low torque of traditional FRP rock bolt, can be prestressed by torque to improve the stability of the supporting structure.
