FiReP® POWERTHREAD® is a system of GFRP Rock Bolts and GFRP 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 continuously threaded profiles the bolts and tubes can be trimmed if required.
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 damages to those while drifting and enlarging tunnels.
