In the demanding realms of mining operations and urban infrastructure development, engineers across Europe and America grapple with challenges like unstable rock masses, corrosive environments, and the need for long-term structural integrity. SupAnchor, a pioneer in geotechnical solutions, addresses these issues with the introduction of the SupFRP® GFRP Solid Bolt. This high-strength anchoring product, crafted from Glassfiber Reinforced Polymer, marks a significant advancement in self drilling anchor systems, offering reliable load-bearing and enhanced durability for complex projects.
The SupAnchor GFRP Solid Bolt is designed with a solid structure, eliminating the hollow weaknesses of traditional injection bolts while capitalizing on GFRP's inherent benefits. Key technical features include a tensile modulus of 45 GPa, ultimate strain of 2.0%, and variants with guaranteed tensile loads ranging from 200 to 500 kN. Its lightweight nature—approximately one-quarter the density of steel—reduces transportation costs and installation labor, making it an efficient component in geotechnical reinforcement systems.
To illustrate the product's capabilities, here are the specifications for the main models:
| Model | Outside Diameter (mm) | Guaranteed Tensile Load (kN) | Weight (kg/m) | Length Options (m) |
|---|---|---|---|---|
| S20/200 | 20 | 200 | 0.52 | 2 to 11 |
| S22/240 | 22 | 240 | 0.62 | 2 to 11 |
| S25/320 | 25 | 320 | 0.83 | 2 to 11 |
| S28/400 | 28 | 400 | 1.04 | 2 to 11 |
| S32/500 | 32 | 500 | 1.30 | 2 to 11 |
The waved thread structure enhances bonding with grouting materials, ensuring stability in diverse geological conditions. This self drilling anchor bolt technology solves engineering challenges by providing corrosion resistance for humid or saline-alkali environments, non-conductivity for safe use near power facilities, and easy on-site cuttability to prevent damage during operations. Compared to hollow bar anchors or drill-and-grout bolts, this solid design offers superior long-term performance without frequent maintenance.
This geotechnical reinforcement system is versatile, finding applications in critical infrastructure projects worldwide. Key uses include:
For instance, in European tunneling projects, the lightweight and high-strength properties of this self drilling anchor system allow for faster installation and reduced structural load. In American mining operations, its non-magnetic nature prevents interference with sensitive equipment, aligning with modern safety standards. The product serves as a durable alternative to solid steel bolts, offering a lifespan that resists rust and material degradation, which is crucial for permanent geotechnical engineering support.
The introduction of the SupAnchor GFRP Solid Bolt contributes significantly to global infrastructure resilience. As urbanization and resource extraction expand, the demand for reliable anchoring solutions grows. This product supports trends towards sustainable construction by minimizing environmental impact through reduced maintenance and longer service life. In the tunneling and mining sectors, it enhances operational efficiency and safety, reducing downtime and lifecycle costs. The geotechnical reinforcement system also addresses regulatory requirements for corrosion protection and electromagnetic compatibility in sensitive projects.
