In Sri Lanka’s coastal belt, chloride from salt air and seawater attacks steel rebar relentlessly. Within a few years reinforcement rusts, swells, and cracks the concrete from the inside — the spalling on seaside buildings, jetties, the coastal railway and water tanks. Repairs never stop, and every monsoon makes it worse.
GFRP Bars That Never Rust — Even by the Sea
Bulk supply of corrosion-proof GFRP bars and GFRP rebar for Sri Lanka's marine, coastal, water and infrastructure projects — delivered to Colombo, duty-advantaged under the India–Sri Lanka FTA, with full engineering support to get them specified.
- 100% corrosion-free — immune to salt & chloride
- 4× lighter than steel — lower freight & handling
- 2× the tensile strength of steel rebar
- ASTM D7957 & ACI 440 compliant

Corrosion-free design life

Rust. Guaranteed.
Corrodes, expands, fails
Chloride penetrates the concrete cover and rusts the steel. The rust expands up to 6× its volume — cracking, spalling and weakening the structure.
- Constant, costly repairs & patching
- Premature replacement — decades early
- Thick concrete cover just to slow it down
Cannot rust. Ever.
Glass fibre and resin are completely immune to chloride and chemical attack. Reinforce once and the structure stays sound for 80+ years — even in the harshest marine conditions.
- Virtually zero corrosion maintenance
- Full design life in coastal & submerged use
Our GFRP bars range
GFRP bars for every part of your structure
A complete range of corrosion-proof GFRP bars — straight bars and factory-bent shapes — manufactured to ASTM D7957 / IS 18256-2023 and supplied cut-to-length for Sri Lankan marine, coastal, water, road and building projects.
Straight GFRP bars
3–22 mm straight bars for slabs, walls, beams and foundations — the everyday workhorse, cut to your lengths.
Bent GFRP bars
Factory-bent L, U, crank and custom shapes to your bar bending schedule. Bending is always done in the factory, never on site.
Custom GFRP bars
Special diameters, shapes and cut-lengths engineered to your drawings for marine, water-retaining and precast work.
GFRP bars vs steel rebar
Why Sri Lankan engineers are switching to GFRP
| Property | Steel rebar (TMT) | MRG GFRP bars |
|---|---|---|
| Corrosion in salt / chloride | Rusts & spalls | 100% immune |
| Tensile strength | ≈ 500–550 MPa | ≈ 1,000+ MPa (2×) |
| Density | Heavy (7,850 kg/m³) | ≈ ¼ of steel (~2000 kg/m³) |
| Service life (coastal) | Often < 30 yrs before repair | 80+ years |
| Maintenance | Ongoing repairs | Virtually none |
| Electrical / magnetic | Conductive & magnetic | Non-conductive, non-magnetic |
| Freight & site handling | Costly, heavy lifts | Light — lower freight & labour |
| Thermal conductivity | High | Low (thermally insulating) |
The real cost question
Yes, it costs more per kg. Here's why it's cheaper overall.
Bent GFRP Bars serve structures where corrosion resistance, weight reduction, or electromagnetic neutrality determines long-term performance. Below are the five environments where MRG Composites Bent GFRP Rebar consistently outperforms steel.
02 — DUTY ADVANTAGE
Duty-advantaged under ISFTA
GFRP is a glass-fibre product (HS 7019), which typically sits outside Sri Lanka's steel import restrictions — so it can ship in under the India–Sri Lanka Free Trade Agreement while imported steel is protected.
01 - LIFECYCLE
Pay once. Forget it.
No corrosion repairs, no early replacement, and a 80+ year life. Over the life of a coastal structure, steel plus its repair bills costs far more than GFRP installed once.
03 — FREIGHT & SITE
4× lighter = cheaper to move
A quarter of steel's weight means lower sea-freight per project and faster, cheaper handling and placement on site — less crane time, less labour, quicker pours.
Where it's used
Built for Sri Lanka's toughest projects
MRG GFRP bars go anywhere concrete meets salt, water or chemicals — the applications where steel corrosion is a matter of when, not if.
Ports & marine
Breakwaters, jetties, quay walls, piles and berths in permanent salt exposure.
Coastal protection
Seawalls, revetments and groynes that hold up against erosion and surge.
Water & wastewater
Treatment plants, tanks, channels and effluent structures — chemical-proof.
Hotels, resorts & pools
Seaside developments and swimming pools where chloride destroys steel.
Railway & bridges
Coastal-line bridge structures, decks and approach slabs in marine and coastal environments.
Precast & industrial floors
Precast elements and factory slabs in wet or corrosive conditions.
Tunnels & soft-eyes
Non-conductive, TBM-friendly reinforcement for tunnelling and MRI/data facilities.

Specification support
Talk to our technical team
Getting GFRP approved — we make it easy
Sri Lanka doesn’t yet have a dedicated SLS standard for GFRP — and it doesn’t need one. Under CIDA / ICTAD specifications, your Engineer can approve materials that conform to recognised international standards. MRG GFRP is manufactured to ASTM D7957, ACI 440.1R, IS 18256-2023 and IRC 137-2022, and we give your consultant everything they need to specify it with confidence.
The fastest route to a big project isn’t a national standard — it’s convincing the specifying engineer. That’s exactly where our technical team works alongside you.
Test reports & material certificates
Full third-party and mill test data for QA/QC files.
Design data & properties
Characteristic values your engineer needs for structural calculations to ACI 440.
Free sample bars for local testing
Send them to any Sri Lankan lab for independent verification.
Specification & BOQ drafting help
We help write the GFRP item so it drops straight into your tender documents.
Direct technical liaison
Our engineers speak directly with your consultant or CECB to answer queries.
