Glass Fiber Reinforced Polymer Rockbolt
The All-Thread GFRP bolt was developed for strata support in mining and tunneling as well as for slope and face stabilization.
Due to its continuous thread, the bolt can be trimmed if needed. The bolt has a high ultimate load and due to its profile, it offers a maximum bondage with all grouting materials. The cuttability protects machinery and equipment and prevents damages to machinery while drifting and enlarging tunnels. The bolt has a high corrosion resistance and is well suited for permanent support.
The high flexibility 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.
Main Advantages
1.All-Thread FRP Bolt: The rod is threaded over the whole length, i.e. "All-Thread";
2.High Corrosion Resistance: The base materials used by the bolt are durable materials, and they are molded through the composite process. The life span is up to 100 years. They can be used as permanent support materials;
3. High Tensile Strength: The load is approximately double that of a steel bar with the same diameter;
4. Low Weight: The weight is only 1/4 that of a steel bar with the same diameter. Therefore, the labor intensity is greatly reduced, and the transportation cost is reduced at the same time;
5. Anti-static: It has no electrical conductivity, and no sparks will be produced when being cut. It is particularly suitable for high gas zones;
6. Non-flammable: It is non-flammable and has high thermal isolation;
7. Cuttability: It avoids damages to cutter heads, and does not delay excavation
