Glass fiber reinforced plastic (GFRP) bolt is formed by high strength glass fiber and resin curing agent through high temperature curing. The whole length of the bolt is thread type, the thread direction is left or right rotation, and the thread distance is generally 10mm round head thread.
After the fiberglass bolt is driven into the rock, under the action of anchoring agent, the fiberglass bolt bolt body is bonded to the surrounding rock mass. Under the interaction between the fiberglass bolt and the surrounding rock mass, the stress state of the surrounding rock is changed, the overall stiffness of the rock mass is improved, and the deformation resistance and bearing capacity of the rock mass are enhanced.
Compare with steel Rockboolt:

◆ Anti-static Conditioning .
◆ Excellent cuttability .
◆ No-conductive(electric, thermal) .
◆ Flame Resistance .
◆ Continuous threaded profile .
◆ Flexibility .
◆ No electrical conductivity .
◆ Wide range of various dimensions
