GFRP rock bolt in mine

Detailed Product Description

 

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
