FRP rebar is a structural reinforcement made from continuous glass fibers embedded in a polymer resin matrix. Unlike traditional steel, it does not corrode, rust, or conduct electricity, making it ideal for harsh or chemically aggressive environments.
Key characteristics:
High tensile strength (600–1200 MPa)
Lightweight (¼ of steel's weight)
Non-corrosive and non-magnetic
Electrically and thermally non-conductive
Easy to handle and install
GTOFRP manufactures FRP rebars using precision pultrusion and winding technology, ensuring consistent fiber alignment and performance in every bar.
The average FRP rebar cost per meter varies depending on diameter, resin system, and fiber content.
While the initial price is slightly higher than steel, the lifecycle cost is significantly lower due to zero corrosion and minimal maintenance.
| Diameter (mm) | Average Cost (USD/m) | Equivalent Steel Cost (USD/m) | Weight Saving |
|---|---|---|---|
| Ø6 | $0.40 – $0.60 | $0.35 – $0.50 | 75% lighter |
| Ø10 | $0.70 – $1.00 | $0.50 – $0.80 | 70% lighter |
| Ø12 | $0.90 – $1.30 | $0.70 – $1.10 | 65% lighter |
| Ø16 | $1.40 – $1.80 | $1.20 – $1.50 | 60% lighter |
Main cost factors:
Fiber type (E-glass vs. basalt vs. carbon)
Resin system (vinyl ester, epoxy, polyester)
Surface treatment (sand-coated, ribbed, helically wrapped)
Manufacturing tolerance and testing standards

Although FRP rebar is less stiff than steel, it outperforms in long-term durability, corrosion resistance, and overall lifecycle value — especially in marine or chemical environments.
GTOFRP's pultrusion and continuous winding processes ensure high-quality reinforcement bars with superior consistency.
Production steps:
Continuous glass fiber roving is impregnated with resin.
Fibers are aligned and pulled through a heated die.
Surface treatments such as sand-coating or spiral wrapping are applied.
Bars are cut and labeled by diameter and batch number.
This process guarantees dimensional accuracy, tensile uniformity, and ISO-certified performance.
See the GTOFRP FRP Production Line Overview for equipment and process details.
FRP rebar is ideal for environments where steel would corrode or lose strength.
Typical applications include:
Bridges and coastal structures – Saltwater-resistant reinforcement
Tunnels and subways – Non-conductive reinforcement around power lines
Chemical plants – Corrosion-proof foundation and containment walls
Marine infrastructure – Piers, docks, and harbor decks
Roadways and bridges – Lightweight and durable structures
Power and utility projects – Electrical isolation and magnetic transparency

| Property | Unit | FRP Rebar (Typical) |
|---|---|---|
| Tensile Strength | MPa | 800–1200 |
| Elastic Modulus | GPa | 45–60 |
| Bond Strength (Concrete) | MPa | 12–18 |
| Density | g/cm³ | 1.9 |
| Thermal Conductivity | W/m·K | 0.3 |
| Water Absorption | % | <0.25 |
These properties make FRP rebar an excellent choice for sustainable construction under extreme exposure conditions.
FRP rebars are easy to cut, bend (pre-shaped), and install using conventional tools.
Installation notes:
Do not bend on-site using heat (use pre-bent bars).
Cut using diamond blade or carbide saw.
Tie with plastic or stainless-steel wire (avoid ferrous ties).
Maintain proper cover thickness to prevent UV degradation.
