Glass Fiber Reinforced Polymer (GFRP) rockbolts provide safe and reliable ground support in mining, tunneling, and slope stabilization projects. They combine high tensile strength, lightweight handling, corrosion resistance, and non-conductive properties, making them superior to traditional steel bolts in aggressive environments. The continuously threaded profile ensures excellent bonding with grout materials and allows trimming on site for flexibility in confined conditions. Their cutting ability minimizes equipment damage during excavation, while immediate load-bearing capacity is achievable with fast-setting resin capsules.

Product Variants & Functions

• GFRP Hollow Rockbolt

  Designed as a grouting anchor, the hollow core allows injection of cement or resin during installation, ensuring strong bonding and improved load transfer. Ideal for tunnels, slopes, and stabilization projects.

• Self-Drilling GFRP Rockbolt

  Combines drilling and anchoring in a single operation. Equipped with a sacrificial drill bit and compatible with couplers for extended length, it is especially suitable for soft soils, weak strata, and areas where pre-drilling is impractical.

• High Torque GFRP Rockbolt

  Engineered to overcome the low torque limitations of conventional FRP dowels. This variant can be prestressed, significantly enhancing support stability and allowing safer long-term reinforcement.

A Complete Systems

To complement the rockbolts, a full range of GFRP accessories such as nuts, plates, and couplings are available. These are designed to match the same durability, lightweight handling, and corrosion resistance as the bolts themselves, ensuring a fully integrated support system. Together, the bolts and accessories deliver safe, efficient, and long-lasting reinforcement solutions for challenging underground environments.
