GFRP Rockbolts

FiReP® POWERTHREAD® is a system of FRP rock bolts and FRP injection tubes with advanced strength and head load. It was developed for strata support in mining and tunnelling as well as for slope and face stabilization.

Due to continuous coarse thread profiles the bolts and tubes can be trimmed if needed. The products have a high ultimate load and due to their profile they offer a maximum bondage with all grouting material. The cutting ability protects machinery and equipment and prevents damage to machinery and equipment while drifting and enlarging tunnels. The bolts and tubes have a high corrosion resistance under acid conditions and are well suited for permanent support.

The improved flexibility of long tendons is well suited for application without couplings in confined locations. Due to its high tensile strength the bolt has a high and immediate load bearing capacity if applied with fast setting resin capsules. The low weight facilitates handling.

Offers an all-thread bolt, provides for high end loading, flexibility, easy handling and antistatic coating (optionally)

FiReP's® POWERTHREAD®technology is primarily used for permanent support of structures, temporary application, for application without coupling in confined locations, in cementious grout, resin capsules and injection of resin

For Powerthread® Rockbolts different types of accessories can be used. FiReP offers nuts such as steel nut, FRP nut and FRP Powernut, plates as well as couplers.
