POWERTHREAD

FiReP® Rockbolt System

· Model K60 / K62 Solid Rods

· Model J64 Tubular Rods

The FiReP® POWERTHREAD GRP Rockbolt was developed for strata support in mining and tunneling as well as for slope and face stabilization.
Due to its continuous thread the bolt can be trimmed if needed. The bolt has a high ultimate load and due to its profile it offers a maximum bondage with all grouting material. The cuttability protects machinery and equipment and prevents damage to machinery while drifting and enlarging tunnels. The bolt has a high corrosion resistance and is well suited for permanent support.
The high flexibility 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.
