Product Description

GFRP rock bolts and GFRP injection tubes with advanced strength and head load. It was developed for strata support in mining and tunneling 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 and prevents damage to machinery 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.
