GFRP vs TMT Steel Rebar
| Property | GFRP Rebar (Aerobar) | TMT Steel Rebar |
|---|---|---|
| Tensile Strength | 1000-1200 MPa (2x Stronger) | 500-550 MPa |
| Corrosion Resistance | Zero / 100% Rust Proof (Permanent) | High (Rust in Humidity/Salt) |
| Weight | 2.1 g/cm³ (4x Lighter) | 7.85 g/cm³ (Heavy) |
| Electrical Conductivity | Non-Conductive Insulator (Safer) | Conductive (Dangerous) |
| Magnetic Properties | Non-Magnetic / Transparent (Smart-Ready) | Magnetic (Interferes with Signals) |
| Thermal Conductivity | Insulator / Stops Heat (Energy Effective) | Conducts Heat (Heat Bridge) |
| Fatigue Resistance | High / Cyclic Loading (Durable) | Low |
| Chemical Resistance | Excellent | Poor in acidic/marine envs |
| Concrete Bond | Excellent (ribbed surface) | Good |
| Lifespan | 100+ Years | 30–50 Years |
| Installation | Easy — Light to handle | Heavy — Needs cranes |
| Maintenance Cost | ZERO | Regular anti-corrosion needed |
| MRI Compatibility | Fully Compatible ✓ | Not Compatible ✗ |
| Radar Transparency | Transparent ✓ | Opaque ✗ |
| Standard Compliance | ASTM D7957, IS 15422 | IS 1786, BIS |
Steel corrodes → concrete spalls → expensive repairs. GFRP eliminates this cycle entirely, saving 40–60% in lifecycle costs.
GFRP Rebar is 75% lighter. Workers can handle it without machinery, reducing labor costs and speeding up construction.
Non-magnetic GFRP is mandatory in MRI rooms, data centers, airports, and military facilities. Steel fails here.
Marine wharves, coastal roads, bridges, chemical plants — anywhere salt, moisture, or chemicals exist, GFRP wins.
