fiberglass hollow anchor bolt Supanchor FGRP is a new generation of Supanchor rock bolt series with a considerably improved torque resistance and bearing load capacity of thread profile for strong jointing with drill bits, nuts and also couplers. Supanchor FGRP self-drilling rock anchor bolts are used for; GRP rock bolt -Face stabilisation -Forepoling -Slope stabilisation - Groud support in soft rock -Systematic rock bolting In combination with injection work of surrounding rock Supanchor FGRP Self-Drilling Bolts for those applications are today state of the art. Due to it's cuttability Supanchor FGRP Self-Drilling Rockbolt is an economical alternative and also enormous advantagies for modern rapid heading method of tunnelling. Furthermore the cuttability protects the machinery and avoid obstructions while drifting or enlarging tunnels. The bolt has a high radial pressure resistance for injections with resins or grout, and is corrosion resistant for permanent support, The SPINMAX offers a high tensile strength end can carry high loads. Ist low weight with high torsional strength makes the belt well suited for works in loose rock up to a maximum hardness of rock by ****0 MPa
