GRP Rock Bolt
GRP rock bolt is made from high strength glass fibers along with an extremely durable vinyl ester resin. The glass fibers impart strength to the rod while the vinyl ester resin imparts excellent corrosion resistance properties in harsh chemical and alkaline environments. GRP rock bolts are used for strata support in mine, tunnel, underground engineering as well as for slope and face stabilization.
