FRP rock bolts are used for strata support in mine;tunnel;undergound engineering as well as for slope and face stabilization.
FRP ROCK BOLT
The FRP composite rock bolt is made from high strength glass fibers along with an extremely durable vinyl ester resin. combining the pultrusion and an inline winding process. All-thread rebar.The glass fibers impart strength to the rod while the vinyl ester resin imparts excellent corrosion resistance properties in harsh chemical and alkaline environments. FRP rock bolts are used for strata support in mine;tunnel;undergound engineering as well as for slope and face stabilization.
Advantages of FRP rock bolt:
Cuttability
High tensile strength
High end loading
Low weight
Easy handling
High torsion strength
No spark
Anti-static conditioning (optionally)
High thermal isolation
No electrical conductivity
High load bearing capacity
Dimension stabilization
Flexibility
