The Most Common Questions About GFRP Rebar

Q: Is GFRP stronger than TMT steel?

In tension yes — 1000–1200 MPa vs 500–550 MPa. But lower stiffness means more deflection. Design accordingly.

Q: What is the price in India?

₹175–₹270/kg depending on diameter. But GFRP is 75% lighter — per-metre cost is often competitive with steel.

Q: Can GFRP be bent on site?

No. All bent bars must be factory-fabricated. Provide bending schedule before production. Straight bars cut with angle grinder on site.

Q: Is GFRP approved by BIS?

Yes. IS 18256:2023 is India's national standard for GFRP rebar. RN Elements supplies with NABL-accredited test reports.

Q: How does GFRP perform in fire?

GFRP loses strength above 300°C, but concrete cover insulates the bar well within standard fire resistance periods.

Q: Minimum order quantity?

500kg upwards. Standard diameters in stock for immediate dispatch.

Q: Special installation training needed?

No. Main differences: no site bending, plastic ties instead of wire, angle grinder cutting.

Q: What is the service life?

75–100 years in normal concrete environments per international studies and IS 18256:2023.

Q: Can I use GFRP in earthquake zones?

Yes for non-seismic elements (slabs, walls, foundations). Steel preferred for columns, shear walls, coupling beams.

Q: How to get a quote?

WhatsApp or enquiry form. Provide diameter, lengths, quantities, delivery location. Response within 24 hours.
