In the challenging terrains of underground mining and civil engineering projects across Europe and North America, unstable geological conditions often pose significant risks to worker safety and structural integrity. SupAnchor's latest innovation, the GFRP friction bolt, addresses these issues head-on, providing a reliable support solution for rock slopes and tunnels. This patented product marks a world-first in the industry, offering a non-metallic alternative that combats corrosion and enhances operational efficiency in harsh environments.
On-site processes in geotechnical projects demand robust materials that can withstand high stresses and corrosive elements. The SupAnchor GFRP friction bolt excels with key parameters such as a tensile strength of 1000 N/mm², density of 2.0 g/cm³, and excellent corrosion resistance. These features directly tackle common engineering challenges like material degradation and safety hazards. For instance, in tunneling applications, the bolt's lightweight nature reduces installation time and costs, while its insulation properties prevent electrical risks. Below is a comparison with traditional steel bolts and specific data for the FB-48 model, illustrating its superior performance.
| Property | Steel Friction Bolt | GFRP Friction Bolt |
| Corrosion Resistance | Low | High |
| Density (g/cm³) | 7.8 | 2.0 |
| Tensile Strength (N/mm²) | 390 | 1000 |
| Electroconductibility | Yes | No |
| Working Temperature | < 1000 °C | -50 °C to 100 °C |
Additionally, the FB-48 model specifications include an outside diameter of 50 mm, bolt ultimate load of 350 kN, end load of 70 kN, and weight of 1.7 kg/m. These parameters ensure the self drilling anchor system can handle high loads while maintaining ease of use in varied conditions.
The GFRP friction bolt is ideally suited for applications in tunneling, mining, and slope stabilization, where its corrosion resistance and safety features prevent accidents and extend structure lifespans. In global infrastructure projects, such as subway expansions or highway constructions, this geotechnical reinforcement system reduces maintenance needs and enhances sustainability. For example, in mining operations, the bolt's easy cutting capability allows it to be processed without damaging equipment, streamlining workflows and lowering costs. This innovation aligns with growing demands for safer, more efficient ground anchor bolt solutions in urban development and resource extraction.
SupAnchor's commitment to R&D and innovation is evident in this product, backed by ISO certifications and a track record of global projects. The company's collaborative approach with engineers and contractors has led to tailored solutions that meet diverse geotechnical needs.
