In challenging geotechnical projects across Europe and North America, engineers grapple with stabilizing slopes and supporting underground structures in corrosive or sensitive environments. SupAnchor® steps forward with its innovative GFRP Solid Bolt, a high-strength anchoring solution designed to address these complexities while ensuring long-term reliability and safety.
The SupAnchor® GFRP Solid Bolt, part of the broader geotechnical reinforcement system, offers a solid structure that eliminates the weaknesses of traditional hollow bar anchors. Key parameters include a high tensile strength up to 500 kN, excellent corrosion resistance for humid or saline-alkali conditions, and a lightweight design at approximately one-fourth the density of steel, reducing labor during installation. This self-drilling anchor bolt is engineered for easy on-site cutting with common tools, preventing damage to machinery in tunneling or mining operations.
| Model | Outside Diameter (mm) | Nominal Cross-sectional Area (mm²) | Guaranteed Tensile Load (kN) | Weight (kg/m) | Length Options (m) |
|---|---|---|---|---|---|
| S20/200 | 20 | 200 | 200 | 0.52 | 2-11 |
| S22/240 | 22 | 240 | 240 | 0.62 | 2-11 |
| S25/320 | 25 | 320 | 320 | 0.83 | 2-11 |
| S28/400 | 28 | 400 | 400 | 1.04 | 2-11 |
| S32/500 | 32 | 500 | 500 | 1.30 | 2-11 |
These specs enable the bolt to perform reliably in applications like slope stabilization and tunnel support, where traditional drill-and-grout bolts may fail due to corrosion or weight issues. The waved thread structure enhances bonding with grouting materials, ensuring consistent mechanical performance in varied rock masses.
The GFRP Solid Bolt is tailored for demanding environments, including underground mining, highway tunneling, and coastal infrastructure projects. Its non-conductive and non-magnetic properties make it safe for use near power facilities or precision instruments, a critical advantage in modern geotechnical engineering. As a durable alternative to solid steel bolts, it supports long-term stability without frequent maintenance, reducing lifecycle costs.
This versatility positions the product as a key component in global infrastructure development, addressing safety concerns in sectors like construction and resource extraction.
SupAnchor® demonstrates its commitment to professional and innovative solutions through rigorous R&D and ISO-certified manufacturing processes. The company's focus on collaborative engineering has led to successful deployments in international projects, from European rail tunnels to North American mining sites. By advancing the geotechnical reinforcement system with products like the GFRP Solid Bolt, SupAnchor enhances operational efficiency and environmental sustainability.
