FRP composite rock bolt is made from high strength glass fibers along with an extremely durable unsaturated resin combining the pultrusion and an inline winding process. All-thread rebar.The glass fibers impart strength to the rod while the unsaturated resin imparts excellent corrosion resistance properties in harsh chemical and alkaline environments. GRP rock bolts are used for strata support in mining tunneling undergound engineering as well as for slope and face stabilization.
