Global infrastructure developers facing aggressive corrosion environments now have a compelling new solution from SupAnchor, a leader in geotechnical reinforcement systems. The company’s newly launched SupFRP® GFRP (Glass Fiber Reinforced Polymer) Reinforcement Rebar combines high tensile strength, exceptional durability, and corrosion resistance to meet the most challenging construction requirements.
As infrastructure ages and coastal construction expands, engineers are turning to advanced materials that can outperform traditional steel reinforcement. The SupFRP® GFRP rebar, manufactured from high-quality corrosion-resistant resin and fiberglass, offers a permanent solution for concrete internal reinforcement. Its versatility allows factory production in various shapes, meeting diverse construction needs from bridge decks to sea walls.
The SupFRP® GFRP rebar is engineered to deliver consistent mechanical properties across a wide range of diameters. Key data for selected sizes are presented below, showcasing the product’s strength-to-weight advantages and its suitability for structural applications where reducing dead load is beneficial.
| Model | Outside Diameter (mm) | Guaranteed Tensile Load (kN) | Tensile Strength (MPa) | E-Modulus (GPa) | Weight (kg/m) |
|---|---|---|---|---|---|
| ReB-8 | 9 | 50.3 | 1000 | 50 | 0.125 |
| ReB-12 | 14 | 113 | 1000 | 50 | 0.28 |
| ReB-16 | 18 | 201 | 1000 | 50 | 0.50 |
| ReB-20 | 23 | 314 | 1000 | 50 | 0.79 |
| ReB-25 | 28 | 491 | 1000 | 50 | 1.20 |
| ReB-32 | 36 | 720 | 900 | 50 | 2.00 |
| ReB-40 | 45 | 1006 | 800 | 50 | 3.10 |
All models feature an ultimate strain of 2% and a consistent tensile E-modulus of 50 GPa, ensuring predictable performance under load. The waved thread structure enhances bonding with concrete, providing excellent pull-out resistance and long-term structural integrity.
Beyond the impressive tensile strength, the GFRP rebar offers several advantages that directly address modern engineering challenges:
The SupFRP® GFRP rebar is designed for a broad spectrum of applications where durability and reliability are paramount. Its adaptability makes it an excellent choice for:
In tunneling and geotechnical works, the GFRP rebar integrates seamlessly with SupAnchor’s existing self drilling anchor system. While the self drilling anchor bolt provides immediate ground support during excavation, the GFRP rebar can serve as permanent or temporary reinforcement in the final lining or soft-eye breakouts. This combination of hollow bar anchor technology and advanced polymer reinforcement demonstrates SupAnchor’s commitment to offering complete geotechnical solutions.
Global infrastructure investment is increasingly focused on sustainability and longevity. Corrosion of steel reinforcement costs billions annually in repairs and premature replacements. The adoption of GFRP rebar can extend the service life of concrete structures to over 100 years, aligning with green building standards and reducing lifecycle carbon footprints.
For tunneling and mining projects, the ability to use non-metallic reinforcement in critical areas such as TBM launch and reception shafts minimizes electromagnetic interference and simplifies excavation procedures. SupAnchor’s position as a leading soil nail system manufacturer and ground anchor bolt factory allows it to leverage decades of experience to deliver products that meet rigorous international standards.
The company’s drill-and-grout bolt series, including the self drilling anchor system, has been widely adopted in major infrastructure projects across Europe, North America, and Asia. The new GFRP rebar extends this portfolio, offering engineers a one-stop shop for both active and passive reinforcement solutions.
SupAnchor has built its reputation on engineering excellence and collaborative partnerships. With ISO 9001 and ISO 14001 certified manufacturing facilities, the company ensures every product meets the highest quality and environmental standards. Dedicated R&D teams continuously refine material formulations and production processes, resulting in products that exceed industry benchmarks.
From the development of the original self drilling anchor bolt to today’s advanced GFRP composites, SupAnchor remains at the forefront of geotechnical reinforcement technology. Its global network of engineers provides technical support from design to installation, embodying the corporate values of Professional, Innovative, Collaborative.
As infrastructure demands evolve, SupAnchor continues to deliver solutions that combine performance, durability, and value. The SupFRP® GFRP Reinforcement Rebar is not just a product—it is a commitment to building a resilient future.
