SupAnchor H25S Self Drilling Fiberglass Reinforcing Bars
Â
Features  Â
Due to it's cuttability SupFRP TM  Self-Drilling Rock Bolt is an economical alternative and also offers enormous advantages for modern rapid heating methods in tunneling.Furthermore the cuttability protects the machinery and avoids obstructions while drifting or enlarging tunnels. The rock bolt has a high radial pressure resistance for injections with resins or grout and is corrosion resistant for permanent support.The SupFRP TM offers a high tensile strength and can carry high loads. Its low weight with high torsional strength makes the bolt well suited for works in loose rock up to a maximum hardness of 60–70 Mpa.
