An Alternative Solution to Corrosive Reinforcing Bars
What is Glass Fiber Reinforced Polymer (GFRP) Rebar?
- Glass Fiber Reinforced Polymer (GFRP) is a composite material made from polymer matrix reinforced and synthetic amalgamated material of plastic and extremely fine fibers of glass. Other fibers used are carbon, aramid or basalt. Rarely, other fibers such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use.
- GFRP was used as an alternative material to the steel rebar. It is lightweight, no-corrosion, superior tensile strength, and high mechanical performance. Installation of the GFRP rebar is similar to steel rebar, but with less handling, transporting and storage problems.
- FRPs are commonly used in the aerospace, automotive, marine, and construction industries.

Ultimate Corrosion Solution
No Corrosion, One-forth the weight, 2 to 3 times Tensile Strength and Higher Mechanical properties than steel.
Advantages of GFRP Rebars
- Impervious to chloride ion and chemical attack
- Tensile strength is greater than steel (2 to 3 times).
- Light weight, one forth to one fifth of steel reinforcing bar.
- Transparent to magnetic filed and radio frequency.
- Thermally and electrically nonconductive.
- Lesser concrete cover is possible.
- Admixtures to reduce corrosion are no longer needed.
- Easily consumed by excavation equipment when used as temporary structures.
- In corrosive environments, service life is much greater than steel.
- Better field handling damage tolerance than epoxy coated steel and no touch-ups required.
- Sustainable and Recyclable
Applications of GFRP Rebars
- Any concrete members susceptible to corrosion by chloride ions or chemicals.
- Any concrete members requiring nonferrous reinforcement due to electromagnetic considerations.
- As a cost-effective alternative to epoxy-coated and galvanized steel.
- As a cost saving alternative to stainless steel bars.
- Where the machinery will consume the reinforced member, mainly in boring, tunneling and mining (e.g. Soft-eye).
- Applications requiring thermal nonconductivity
- In mass concrete exposed to chlorides near chloride exposure in hybrid applications with steel.
