In challenging geotechnical projects worldwide, from unstable slopes in humid regions to deep underground tunnels in corrosive environments, engineers grapple with ensuring long-term structural integrity. SupAnchor, a pioneer in geotechnical reinforcement systems, responds with the introduction of the SupFRP® GFRP Solid Bolt, a product designed to provide reliable load-bearing and enhanced durability for modern infrastructure demands. This development underscores the company's commitment to professional, innovative, and collaborative solutions in the face of increasing engineering complexities.
The SupFRP GFRP Solid Bolt, made from high-quality Glassfiber Reinforced Polymer (GFRP), addresses common pitfalls in geotechnical engineering by eliminating hollow structures found in traditional bolts. This solid design enhances load-bearing capacity while retaining key advantages such as corrosion resistance, lightweight properties, and non-conductivity. Key technical specifications, derived from extensive research, include high tensile strength, with models offering guaranteed tensile loads from 200 kN to 500 kN, and diameters ranging from 20 mm to 32 mm. These features make it an ideal component in self-drilling anchor systems and drill-and-grout bolt applications, particularly in scenarios requiring minimal maintenance and high safety standards.
For instance, in slope stabilization projects, the bolt's excellent corrosion resistance ensures performance in saline-alkali conditions, while its lightweight nature—approximately one-fourth the density of steel—reduces installation labor and transportation costs. The following table summarizes key technical data, highlighting how these specs solve engineering challenges like load distribution and environmental durability:
| Model | Outside Diameter (mm) | Guaranteed Tensile Load (kN) | Weight (kg/m) | Key Application |
|---|---|---|---|---|
| S20/200 | 20 | 200 | 0.52 | Light-duty rock mass anchoring |
| S22/240 | 22 | 240 | 0.62 | Moderate slope stabilization |
| S25/320 | 25 | 320 | 0.83 | Tunnel roof support |
| S28/400 | 28 | 400 | 1.04 | Mine roadway reinforcement |
| S32/500 | 32 | 500 | 1.30 | Heavy-duty geotechnical projects |
The waved thread structure on these bolts enhances bonding with grouting materials, improving stability in rock masses. Additionally, the non-conductive and non-magnetic properties make them safe for use near sensitive facilities, such as power lines or precision instruments, reducing risks in complex engineering environments.
This geotechnical reinforcement system is primarily deployed in critical sectors like tunneling, mining, and civil engineering. For example, in underground tunnel projects, the SupFRP GFRP Solid Bolt provides reliable wall and roof support, with its long service life resisting rust and degradation in humid conditions. In mining applications, it reinforces roadways, offering a durable alternative to steel bolts that may corrode over time. The product's easy cuttability allows on-site customization with common tools, avoiding damage to machinery during operations—a key advantage in dynamic mining or tunneling sites.
These applications highlight the bolt's adaptability, making it a valuable tool in self-drilling anchor systems and hollow bar anchor setups, where precision and durability are paramount.
The introduction of the SupFRP GFRP Solid Bolt aligns with growing global demands for safer and more efficient geotechnical solutions. As infrastructure projects expand in Europe and America, the need for reliable anchoring products increases, particularly in harsh environments. This product contributes to geotechnical safety by reducing maintenance frequency and enhancing structural stability, which is crucial for large-scale tunneling and mining operations. By offering a lightweight and corrosion-resistant option, it lowers overall project costs and environmental impact, supporting sustainable development goals.
SupAnchor's brand influence is bolstered by its focus on innovation and collaboration. With ISO certifications and a track record in global projects, the company leverages extensive R&D to develop products like this bolt, ensuring they meet international standards. The brand's message of professionalism is evident in the detailed technical data and customer-centric design, which prioritize long-term performance over short-term gains. As a soil nail system manufacturer and ground anchor bolt factory, SupAnchor continues to set benchmarks in the geotechnical reinforcement industry, fostering partnerships that drive technological advancement.
In conclusion, the SupFRP GFRP Solid Bolt represents a significant step forward in geotechnical engineering, combining high-strength materials with practical features to address real-world challenges. Its integration into self-drilling anchor systems and drill-and-grout bolt applications underscores SupAnchor's role as a leader in the field, poised to support future infrastructure growth with reliable, innovative solutions.
