FRP Fiberglass Rebar

Product Introduction

FRP fiberglass rebar (GFRP rebar) is a non-metallic reinforcing bar for concrete, manufactured by pultrusion of continuous glass fibers and resin matrix. As an alternative to conventional steel rebar, it is applicable to various modern concrete projects such as bridges, roads, tunnels, underground works, coastal infrastructure and buildings with special electromagnetic requirements, providing reinforcement solutions for concrete structures.

We supply straight rebars, coiled continuous rebars and custom pre-bent rebars. Bulk supply and dimensional customization are available with direct factory delivery for convenient project procurement. Ribbed surface design improves bonding and anchorage with concrete to guarantee engineering performance.

Core Product Features

✅ Excellent corrosion resistance

Made of non-metallic composite material, it resists erosion by chloride ions and saline-alkali environments, mitigating structural deterioration caused by rust. Suitable for coastal areas and saline soil conditions to extend structural service life.

✅ Lightweight for easy handling

Lighter than steel rebar of the same specification, facilitating transportation, handling and on-site placement and reducing construction labor intensity.

✅ Non-conductive and non-magnetic

Insulating and non-magnetic, suitable for buildings with strict electromagnetic requirements to eliminate electromagnetic interference risks.

✅ Multiple forms available with customization

Coiled FRP rebar: supplied in continuous long lengths and cut on site, ideal for large-area reinforcement; Custom pre-bent FRP rebar: pre-formed in the factory for direct installation upon delivery to boost construction efficiency; Straight ribbed FRP rebar: standard sizes available, with adjustable dimensions per project requirements.

✅ Suitable for long-term service

Under proper design and compliant construction, it achieves a long service life and reduces maintenance work caused by steel corrosion.

Main Application Scenarios

Road & Bridge Construction: bridge deck paving and concrete road structures to resist corrosion from de-icing salts; Tunnel and Underground Works: shield tunnels and underground diaphragm walls. Its cuttable property adapts to shield excavation;

Coastal and Marine Projects: concrete structures in saline and corrosive environments such as wharves and revetments; Buildings with Special Electromagnetic Requirements: MRI rooms, electromagnetic laboratories and similar sites to avoid electromagnetic disturbance from steel reinforcement;

Other Concrete Infrastructure: anti-corrosion projects including water tanks, sewage treatment facilities and parking slabs.

FAQ

Q1: Can FRP fiberglass rebar directly replace ordinary steel rebar?

A: Direct equivalent replacement is not allowed. FRP rebar differs from steel rebar in mechanical properties including elastic modulus and shear resistance. Structural calculation and reinforcement design shall be carried out in accordance with relevant national standards (JG/T 406‑2013, GB 50608‑2010, etc.) prior to application.

Q2: What is the anti-corrosion mechanism of fiberglass rebar?

A: It is a non-metallic composite composed of glass fiber and resin without the mechanism of metallic oxidation and rusting. It is less prone to corrosion damage in saline and chloride-rich environments. Nevertheless, the resin matrix is vulnerable to high temperature and strong chemical media, so material selection shall match site conditions.

Q3: Can the rebar be bent? Is on-site cold bending permitted?

A: Bending can be completed in the factory as custom pre-bent products. On-site cold bending is not recommended. FRP rebar is relatively brittle; on-site bending may damage internal fibers and impair mechanical performance. Submit drawings at the time of order if bent shapes are required for factory prefabrication.

Q4: What specifications are available and is dimensional customization supported?

A: Standard diameters range from 6 mm to 32 mm. Length and bent shapes can be customized per project drawings. Special production is available for bulk projects. Please submit drawings for evaluation.

Q5: Is FRP rebar conductive or magnetic? What special scenarios is it suitable for?

A: Standard GFRP fiberglass rebar is insulating and non-magnetic, suitable for magnetically and electrically sensitive spaces such as MRI rooms and electromagnetic laboratories. Carbon fiber FRP rebar is conductive, so material type shall be distinguished during selection.

Q6: What are the key points for construction?

A: ① Avoid striking or forced bending on site; ② Ties and spacer blocks shall match the material characteristics of FRP rebar; ③ Anchorage and lap lengths shall follow FRP design codes instead of steel rebar parameters; ④ Prevent long-term direct sunlight exposure during storage and apply covering protection.

Q7: Can inspection reports be provided?

A: Factory quality certificates are available. Third-party test reports can be arranged upon project request.

Q8: How to choose between coiled rebar and straight rebar?

A: Coiled continuous rebar is preferred for large-area paving and long-distance reinforcement to reduce joints via on-site cutting. Straight rebar suits reinforcement of beams, columns and local members. Factory pre-bent finished rebar is recommended for components with complex shapes.
