GFRP Rebar

What is a GFRP rebar? 

GFRP (Glass Fiber Reinforced Polymer) rebar, commonly referred to as Fiberglass reinforcement, is a high tensile strength alternative to steel reinforcement.

GFRP REBAR Composite Rebar is used in transportation infrastructure, rail LRT, runways, IT and research facilities, mining and tunneling, buildings, and waterside concrete structures such as retaining, sea walls, dams, and power plants have to be reinforced with corrosion-resistant rebar

Fiberglass reinforcing is highly resistant to corrosion and can extend the lifespan of concrete structures enormously

The steel is used in constructions like buildings, tunnels, waterside concrete, etc, Due to climate and exposure to chlorides causes major corrosion issues. Governments, constructors, and building owners are facing so much money for repairing dangerous failures.

Advantages of GFRP REBAR

GFRP Rebar 2x stronger
  • GFRP rebar is ¼ the lighter than steel and 2x the stronger than steel.
  • It’s more durable and cost-effective than steel
  • Fiberglass rebar “MRG Composites” has a high tensile strength which indicates they are at least 2 times stronger than conventional steel of the same diameter. This enables consumers in some cases to replace the diameter of steel with a smaller diameter of MRG Bars without any loss of performance.
  • The constituents of GFRP include high-quality corrosion-resistant vinyl ester resin that increases the lifespan of a concrete structure.
  • It can be manufactured in custom lengths, bends, and shapes
  • When deciding between composite and steel rebars, durability will play a big role. Where MRG Bars are 100% non-corrosive and have a life of over 2 times compared with steel reinforcement, this makes it an easy winner and the one to choose.
GFRP Rebar 2x life
GFRP Rebar 4 lighter
  • It is transparent to electrical field and radio frequencies
  • Low thermal conductivity
  • This bar has a much higher coefficient of thermal expansion in the transverse direction than that of steel
  • As the density of glass-fiber reinforcement is only 1.9 Tons/cubic meter, it makes our bars nearly 4 times lighter than conventional reinforcement bars. This means that the handling, transportation, and overall experience on-site become very easy.

1) Why MRG Composite GFRP Rebar?

Ans.  MRG Composite Rebar provides a corrosion-free rebar alternative with an extended asset lifespan in the most challenging and corrosive environments. MRG Composite Rebar are light weight, durable, and easy to install.

2) What is the difference between GFRP and FRP rebar?

Ans. GFRP stands for Glass Fiber-Reinforced Polymer is one of the best Rebar used for constructions, FRP stands for Fibre Reinforced Polymer which includes basalt (BFRP) and carbon (CFRP),

3) Is GFRP rebar cost-competitive against steel?

Ans. GFRP Rebars are two times stronger and 1/4 times lighter than steel, The constituents of GFRP include high-quality corrosion-resistant vinyl ester resin that increases the lifespan of a concrete structure, It can be manufactured in custom length, width etc. all the parameters are considered during constructions and can save your cost as compare to steel rebars.

4) How does GFRP rebar work during an earthquake?

Ans. Due to higher fatigue properties, GFRP rebars have higher resistance to cyclical loads of high intensity which makes MRG rebars workable during earthquakes.

5) Can you bend/curve GFRP Rebar on site?

Ans. No, as mechanical properties are elastics, thus it does not allow you to bend material on site. on the other hand you can get desired curved element pre-fabricated as per your requirements.


  • We chose MRG GFRP REBARS for Residential bungalows. It’s usage proved to be beneficial for us as the installation took notably less time compared to other previously used materials. Also, it proved to be a cost-effective alternative for us.

  • We used MRG GFRP REBARS for building water tanks. These rebars have many benefits, but the ease of transport and customisable lengths were what caught our attention.

    - Siddik Kathiwala
    - OK Traders
  • Mrg rebars have made our construction easier therefore we decided to become their authorised distributors. As a result, we have supplied mrg rebars to many companies for their RCC roads, Industrial flooring, boundary walls, non structural walls, pcc and other applications.

    - Ingawale patil
    - IPCC Infra Pvt. Ltd. (authorized dealer)
  • As a result of our satisfied experience with MRG GFRP REBARS, we became Authorized Dealers. Since becoming Authorised Dealers, we have sent out rebars for RCC roads, industrial flooring, boundary walls, non structural walls, pcc, ect.
