Questions, flipped over.

Glass Fibre Reinforced Polymer rebar is made of high-strength glass fibres bound in a durable polymer resin — it reinforces concrete like steel, but never corrodes.

Yes, on a like-for-strength basis. Because GFRP carries about twice the tensile stress of steel, our engineers give you the exact equivalent diameters and spacing.

In tension, yes — typically 1000–1200 MPa versus 500–600 for steel. Its stiffness is lower, which the structural design simply accounts for.

There is no metal to rust. Glass and resin are chemically inert, so moisture, chlorides and alkalis have nothing to attack.

Design service life exceeds 100 years, against roughly 30–50 for steel in damp, coastal or chemically aggressive conditions.

Yes. Endurobar is BIS-licensed and made to IS 18256:2023 and IS 18255:2023, with ASTM D7957 conformance and NHAI approval.

No — bends are formed during manufacture. Send us your bar-bending schedule and we deliver ready-made bent bars, stirrups and links.

Standard diameters from 3mm to 25mm in 6m, 9m and 12m lengths, plus custom lengths and shapes to order.

It can cost more per kg, but lighter weight, zero maintenance and a century-long life usually make it cheaper over the life of the structure.

Yes — roughly a quarter of the weight, which cuts transport, crane and labour costs and speeds up installation.

Yes, easily, with an ordinary abrasive disc cutter — no special tools required.

No. It is fully dielectric and non-magnetic, making it ideal near MRI machines, transformers and railway signalling.

Especially well — the salt spray and sea water that destroy steel have no effect on GFRP.

Yes — it is inert to the chlorine, sulphates and effluent chemicals that corrode steel.

Bars are tied with plastic or coated ties and placed just like steel; most crews adapt in a single session.

Because there is no corrosion to guard against, cover can often be reduced, saving material and weight.

Concrete provides the primary fire protection; GFRP is specified with appropriate cover for the required fire rating.

Yes — we manufacture to schedule and accept bulk and repeat orders with full batch traceability.

Yes — our engineers convert your steel schedule to an equivalent GFRP spec at no obligation.
