The rebar that never rusts. Engineered to endure.
2× stronger, 4× lighter and 100% corrosion-free — built for long-term durability.Endurobar GFRP reinforcement is 2× stronger than steel, 4× lighter and 100% corrosion-free — delivering concrete structures designed to stand for over a century.
By The Numbers
A track record built to last
Why Endurobar
Composite reinforcement, re-engineered.
Glass Fibre Reinforced Polymer replaces corrodible steel with high-tensile glass fibres bound in resin — solving the single biggest cause of concrete failure.
100% Corrosion-Free
Immune to moisture, chlorides and alkaline attack. No rust, no spalling — concrete stays sound for its full service life.
2× The Tensile Strength
1000–1200 MPa tensile strength — roughly double conventional steel — so you achieve the same capacity with less material.
4× Lighter To Handle
At a quarter of steel's weight, Endurobar slashes transport, crane and labour costs and speeds up every pour.
Built For Long-Term Durability
With no steel to corrode, the reinforcement itself does not rust — fewer repair cycles and a dramatically lower whole-life cost.
Non-Conductive & Non-Magnetic
Fully dielectric and radio-transparent — ideal for MRI suites, transformer pads, airport pads and light-rail systems.
Sustainable & Zero-Maintenance
No emissions in storage or use, no repair cycles, no cathodic protection — a genuinely lower-carbon reinforcement.
GFRP vs. Steel
The numbers aren't close.

Product Range
One material. Every form your structure needs.
Strength, And Then Some
The strongest decision in a build is the one buried in the concrete.
A single Endurobar bar carries the tensile load of a steel bar twice its size — at a quarter of the weight, and with zero risk of the corrosion that quietly destroys concrete from within.
Where It Works
Reinforcing the toughest environments
01Bridges & Decks
Decks, approach slabs and MSE walls exposed to de-icing salt and spray.
02Foundations & Basements
Footings, rafts, retaining and compound walls built for long-term durability.
03Swimming Pools
Pool shells and decks that never rust, stain or crack in chlorinated water.
04Septic Tanks
STPs, ETPs and septic structures in permanently wet, aggressive settings.
From Enquiry to Site
How we deliver
Consult & Specify
Our engineers review your drawings and recommend the exact GFRP equivalents by tensile capacity.
Precision Manufacture
Bars and cages are pultruded and cut to schedule with full batch-level traceability.
Test & Certify
Every batch is tested to IS 18256/18255 and ASTM D7957 before it leaves the floor.
Deliver & Support
Lightweight loads ship fast, and our team supports your crew through installation.
Trusted On Site
Engineers who switched, stayed.
“We spec'd Endurobar for a coastal water tank. Two monsoons in, zero corrosion and the crew loved how light it was to place.”
“The tensile numbers let us reduce bar count. Faster pours, lower freight, and a corrosion-free life on paper. Easy decision.”
“BIS licence and batch traceability were what our client demanded. Endurobar delivered the paperwork and the performance.”
