GFRP Rebar
Teknomatic Engineering produces premium GFRP (Glass Fiber Reinforced Polymer) Rebar , engineered for concrete reinforcement in environments demanding corrosion resistance, electrical insulation, and long-term durability. These rebars are especially suited for marine, chemical, bridge, and infrastructure applications.
Our GFRP Rebars are manufactured under rigorous quality controls, crafted to comply with Indian and international standards. They deliver a combination of high strength, lightweight behavior, and resistance to aggressive environments to extend the service life of reinforced concrete structures.
Key Features & Benefits
- Excellent Corrosion Resistance: Immune to rust, chloride, and alkaline attack in concrete.
- High Strength-to-Weight Ratio: Strong tensile performance while being lighter than steel.
- Non-Conductive & Non-Magnetic: Safe in electrical, MRI, or sensitive equipment areas.
- Thermal Compatibility: Coefficient of thermal expansion closer to concrete, reducing internal stresses.
- Low Maintenance & Long Life: Minimizes repair costs over structure lifetime.
- Standards Compliance: Designed to meet IS 18256:2023 and IS 18255:2023 testing protocols.
- Lightweight Handling: Facilitates easier transport and installation on site.
Specifications & Range
Below is a typical specification summary for GFRP Rebars. Actual values should be confirmed per your product’s test certificates and design requirements.
| Parameter | Typical Range / Value | Notes / Reference |
|---|---|---|
| Diameters Available | 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm, 18 mm, 20 mm, up to ~32 mm | Smaller diameters sometimes supplied in coils; larger as straight bars. |
| Length / Packaging | Straight bars up to 12 m; coils for small diameters; custom cut lengths available | Depends on project logistics and handling constraints. |
| Tensile Strength (Ultimate) | ≈ 800 – 1,300 MPa (depending on diameter, resin, fiber content) | Strength may reduce slightly for higher diameters. |
| Modulus of Elasticity | ≈ 45 – 60 GPa | Lower than steel; influences deflection and member design. |
| Elongation at Break | ~ 1.5 % to 3.0 % | GFRP behaves in a brittle manner—no yield plateau as in steel. |
| Density | ~ 1.90 – 2.20 g/cm³ (≈ 1,900 – 2,200 kg/m³) | About one-fourth the density of steel rebar. |
| Standards / Codes | IS 18256:2023, IS 18255:2023 (testing) & applicable international FRP / ACI guides | IS 18256 defines specification for solid round GFRP bars. |
Why Choose Our GFRP Rebar?
Teknomatic’s GFRP Rebars bring advantages over traditional steel rebars, especially in aggressive or demanding environments:
- Superior Durability: Withstands chloride, acid, and weather exposure.
- Life-Cycle Cost Savings: Minimal maintenance and replacement costs.
- Structural Efficiency: Lighter reinforcement lowers structural dead load.
- Compatibility with Concrete: Thermal expansion close to concrete minimizes stress from temperature changes.
- Safe in Sensitive Zones: Non-magnetic and non-conductive—suitable near electrical, MRI, or other sensitive installations.
- Quality Assurance: Manufactured and tested per latest Indian standards and verified with certified test reports.
