GFRP vs TMT Steel: Head-to-Head
Technical comparison of material properties and performance characteristics
| Property | GFRP (PRO BAR) | TMT Steel | Key Difference |
|---|---|---|---|
| Tensile Strength | 1171 MPa | 500 MPa | GFRP carries ~2.3x higher tensile stress per mm² |
| Weight/Meter (8mm) | 0.105 kg | 0.395 kg | GFRP is ~75% lighter |
| Bar Length | No limitations | 12 meters | Continuous lengths reduce lap joints |
| Durability (embedded) | 100 years | 50 years | GFRP is non-corrosive |
| Corrosion Resistance | Yes | No | Eliminates cover-related failures |
| Electric Conductivity | No | Yes | Suitable for power plants, data centers, MRI rooms |
| Thermal Conductivity | No | Yes | Reduces thermal bridging |
| Shear Strength | 170 MPa | 120 MPa | Higher shear strength |
| Bond Strength | 14 MPa | 9-10 MPa | Modified development length |
| Modulus of Elasticity | 46 GPa | 160-200 GPa | Deflection governs design, not failure |
| Density | 2.1 ton/m³ | 7.8 ton/m³ | Improves seismic performance |
Green Building
Sustainability & LEED Alignment
GFRP contributes to sustainable construction practices and can help projects achieve green building certifications. The material's longevity and maintenance-free nature significantly reduce environmental impact over time.
- Contributes to LEED certification points
- Lower embodied carbon than steel production
- Eliminates chemical corrosion treatments
- Reduces construction waste
- Longer service life = fewer replacements
- Non-toxic and environmentally inert
