SupAnchor® Launches GFRP Solid Bolt to Revolutionize Geotechnical Reinforcement Systems

In the rugged terrains of a major European tunneling project, engineers faced persistent challenges with corrosion and heavy load-bearing in humid, saline environments. Traditional steel bolts were prone to rust, compromising long-term stability and increasing maintenance costs. Enter SupAnchor®, a leader in geotechnical solutions, which has unveiled its latest innovation: the SupFRP® GFRP Solid Bolt. This high-strength, solid-structured anchoring product is designed to address such engineering hurdles, providing a durable alternative for rock mass support, slope stabilization, and underground structure reinforcement. As infrastructure demands grow across Europe and North America, this launch marks a significant step towards safer, more sustainable geotechnical engineering.

Technical Parameters and Performance Excellence

The SupFRP® GFRP Solid Bolt eliminates the hollow structure of conventional injection bolts, leveraging Glassfiber Reinforced Polymer (GFRP) for enhanced reliability. Key technical features include a high tensile strength, with guaranteed loads ranging from 200 kN to 500 kN across models, ensuring stable load-bearing in critical applications like mine roadway reinforcement. Its corrosion resistance makes it ideal for harsh environments, such as saline-alkali areas or near power facilities where non-conductivity is crucial. Weighing approximately one-fourth of steel, the bolt reduces transportation and installation labor, while its easy cuttability allows on-site adjustments without damaging machinery.

To illustrate the product's engineering adaptability, here are the technical specifications for select models, highlighting how they solve common challenges in geotechnical projects:

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

These parameters, including a tensile E-modulus of 45 GPa and ultimate strain of 2.0%, ensure consistent performance in varying geological conditions. The waved thread structure enhances bonding with grouting materials, making it a versatile component in drill-and-grout bolt systems. For instance, in slope stabilization projects, the bolt's lightweight nature facilitates quicker installation, while its corrosion resistance extends service life without frequent replacements.

Application Scenarios and Market Adaptability

The GFRP solid bolt is engineered for diverse geotechnical reinforcement systems, from temporary supports to permanent structures. Primary applications include:

  • Slope Stabilization: In hilly regions prone to erosion, the bolt provides reliable anchoring to prevent landslides, with its non-conductive properties ensuring safety near electrical infrastructure.
  • Underground Tunnel Support: For subway or mining tunnels, the product reinforces roof and wall structures, leveraging high tensile strength to bear dynamic loads from surrounding rock masses.
  • Mine Roadway Reinforcement: In corrosive mining environments, it resists material degradation, reducing downtime and maintenance costs compared to traditional hollow bar anchors.
  • Rock Mass Anchoring: Suitable for projects in coastal or industrial areas where saline or chemical exposure is a concern, enhancing long-term structural integrity.

This adaptability aligns with growing demands in global infrastructure, where engineers seek efficient, durable solutions for complex geotechnical challenges. The bolt's design complements SupAnchor's broader portfolio, including self-drilling anchor systems, offering a cohesive approach to ground anchor bolt manufacturing.
