Comparison
GFRP Rebar vs Steel Rebar
A side-by-side comparison of GFRP (Glass Fiber Reinforced Polymer) rebar versus traditional steel reinforcement.
| Property | GFRP Rebar | Steel Rebar |
|---|---|---|
| Corrosion Resistance | Excellent — will not rust | Corrodes in chloride/wet environments |
| Tensile Strength | ≥ 1,000 MPa | 420 MPa (Grade 60) |
| Weight | 75% lighter than steel | Heavy |
| Density | ~2.0 g/cm³ | 7.85 g/cm³ |
| Electrical Conductivity | Non-conductive | Conductive |
| Magnetic | Non-magnetic | Magnetic |
| Thermal Conductivity | Low | High |
| Elastic Modulus | 40–60 GPa | 200 GPa |
| Service Life (Corrosive Env.) | 75–100+ years | 15–25 years (needs repair) |
| Lifecycle Cost | Lower (no maintenance) | Higher (repair & coating) |
| On-Site Bending | Pre-bent factory shapes | Can be bent on site |
| Transport Cost | Lower per meter | Higher per meter |
* Selection depends on project environment, design requirements, and applicable standards (ASTM D7957 / ACI 440.1R).

Why Choose Us
Key Features & Benefits
Superior Corrosion Resistance
Unlike steel, GFRP rebar will never rust or corrode — even in harsh chemical, marine, or deicing salt environments. Eliminates spalling and extends structure lifespan by 50+ years.
High Tensile Strength
With tensile strength exceeding 1,000 MPa, our GFRP rebar delivers twice the strength of standard steel rebar at a fraction of the weight, enabling lighter and more efficient structural designs.
75% Lighter Than Steel
At only 1/4 the weight of steel, GFRP rebar dramatically reduces transportation costs, simplifies on-site handling, and accelerates installation — especially in complex formwork.
Non-Conductive & Electromagnetically Neutral
GFRP rebar is electrically non-conductive and non-magnetic, making it the ideal reinforcement for MRI suites, electrical substations, laboratories, and sensitive electronic facilities.
Cost-Effective Lifecycle Savings
While the initial material cost is comparable to epoxy-coated steel, GFRP rebar eliminates future maintenance and repair costs — delivering up to 30% total lifecycle savings in aggressive environments.
ASTM D7957 Certified Quality
Every production batch is tested and certified to meet ASTM D7957 and ACI 440.1R standards, ensuring consistent quality, dimensional accuracy, and traceability for every shipment.
