FiReP® POWERTHREAD® is a continuously threaded, high strength rock bolting solution. Developed for strata support in mining and tunnelling, it has proven to be a versatile product for many applications. The FRP system allows the bolts to be cut to length as required on location, as well as protecting equipment and machinery of they are required to be mined through. Due to it's high corrosion resistance, FiReP® POWERTHREAD® is perfectly suited for long term and temporary ground support.
FiReP® POWERTHREAD® is available as either solid or hollow bolts, with detailed information available in the TDS.
