FAQ
GFRP rebar is a high-strength, corrosion-resistant reinforcing bar made from glass fiber and polymer resin, used as an alternative to steel in concrete reinforcement.
It is used in:
- Bridges, tunnels, marine structures
- Chemical plants and industrial floors
- Coastal constructions, swimming pools
- MRI rooms, nuclear plants (non-magnetic areas)

No. GFRP rebar cannot be bent on-site like steel. It must be pre-bent at the factory as per design requirements.
GFRP has limited fire resistance compared to steel. It softens above 150–200°C. Special fire-resistant resins or coatings can be used if required.
Yes, GFRP has high tensile strength, but lower modulus of elasticity than steel, making it more flexible. It is ideal for corrosion zones and crack control applications.
GFRP rebars can last over 100 years in most environments due to their corrosion-free nature, reducing long-term maintenance costs significantly.
Although the initial cost is higher than steel, the long-term savings from zero corrosion, low maintenance, and longer service life make it very cost-effective.
GFRP rebars are available in 8mm to 32mm diameters. They conform to IS 17375, ASTM D7957, ACI 440, and are supplied in straight, coil, or pre-bent forms.
