Note: Prices are per bundle (approximate weights: 8mm=~47kg, 10mm=~53kg, 12mm=~54kg, 16mm=~57kg). Prices subject to market fluctuations. Last updated: April 2026.
Transportation costs and local dealer margins cause price variations across Bihar cities. Here's what you can expect:
| City | 8mm (Rs) | 10mm (Rs) | 12mm (Rs) | 16mm (Rs) | Price Variation |
|---|---|---|---|---|---|
| Patna | 58-62/kg | 58-62/kg | 59-63/kg | 60-64/kg | Base price (lowest) |
| Gaya | 59-63/kg | 59-63/kg | 60-64/kg | 61-65/kg | +1-2 Rs/kg vs Patna |
| Bhagalpur | 59-63/kg | 59-63/kg | 60-64/kg | 61-65/kg | +1-2 Rs/kg vs Patna |
| Muzaffarpur | 58-62/kg | 58-62/kg | 59-63/kg | 60-64/kg | Similar to Patna |
| Darbhanga | 59-63/kg | 59-63/kg | 60-64/kg | 61-65/kg | +1-2 Rs/kg vs Patna |
| Purnia | 60-64/kg | 60-64/kg | 61-65/kg | 62-66/kg | +2-3 Rs/kg vs Patna |
| Arrah | 58-62/kg | 58-62/kg | 59-63/kg | 60-64/kg | Similar to Patna |
| Begusarai | 59-63/kg | 59-63/kg | 60-64/kg | 61-65/kg | +1-2 Rs/kg vs Patna |
Choosing the right grade is crucial for structural integrity. Here's what each grade means:
For most residential construction in Bihar, Fe 500D is the recommended choice due to the state's seismic zone classification (Zone IV - high damage risk zone).

Understanding weight helps you verify dealer billing and calculate exact requirements:
| Diameter (mm) | Weight per Meter (kg) | Standard Length (m) | Weight per Bar (kg) | Bars per Bundle | Bundle Weight (kg) |
|---|---|---|---|---|---|
| 8mm | 0.395 | 12 | 4.74 | 10 | 47.4 |
| 10mm | 0.617 | 12 | 7.40 | 7 | 51.8 |
| 12mm | 0.888 | 12 | 10.66 | 5 | 53.3 |
| 16mm | 1.580 | 12 | 18.96 | 3 | 56.9 |
| 20mm | 2.469 | 12 | 29.63 | 2 | 59.3 |
| 25mm | 3.856 | 12 | 46.27 | 1 | 46.3 |
Formula: Weight per meter = D²/162 (where D is diameter in mm)
Example: 12mm bar = 12²/162 = 144/162 = 0.888 kg/meter
Planning a large construction project? Here's how to save 5-15% on TMT bar costs:
Retail dealers add 3-5% margin. For orders above 5 tonnes, contact authorized stockists directly. Major brands have stockists in Patna, Gaya, and Bhagalpur industrial areas.
Steel prices typically drop during:
Ordering 8mm, 10mm, 12mm, and 16mm together from one dealer often triggers bulk discounts (2-3% off).
October-February sees high demand due to favorable weather. Prices can be 5-8% higher. If possible, schedule major purchases during off-peak months.
Some dealers underweight bundles by 2-3%. Always weigh bundles or count bars. A 12mm bundle should have exactly 5 bars of 12m length.
While Tata and JSW are premium, brands like Shyam, Bhushan, and Essar offer 5-8% savings with adequate quality for residential construction. Ensure BIS certification.

Counterfeit steel is a serious problem in Bihar. Follow these verification steps:
Genuine TMT bars have BIS (Bureau of Indian Standards) mark stamped on every bar. Look for IS 1786 certification.
Each bar should have the brand name and grade embossed (e.g., "TATA TMT Fe500D"). Faded or missing markings indicate counterfeit products.
Genuine TMT bars have:
Reputable dealers provide mill test certificates showing chemical composition and mechanical properties. Don't hesitate to ask.

Estimate your requirements before visiting dealers:
| House Type | Approx. Area (sq ft) | TMT Required (tonnes) | Estimated Cost (Rs) |
|---|---|---|---|
| 1 BHK | 600-800 | 2.5-3.5 | 1,50,000-2,20,000 |
| 2 BHK | 900-1200 | 4-6 | 2,40,000-3,80,000 |
| 3 BHK | 1300-1800 | 6-9 | 3,60,000-5,70,000 |
| 4 BHK / Duplex | 2000-3000 | 10-15 | 6,00,000-9,50,000 |
Note: Estimates assume standard RCC design. Actual requirements vary by structural engineer's design, soil conditions, and seismic zone considerations.
Answer: Tata TMT and JSW Neosteel are top choices for premium quality. For budget-conscious buyers, SAIL and Jindal offer good value. All major brands are suitable for Bihar's seismic zone if you choose Fe 500D grade.
Answer: Transportation costs from steel plants, local dealer margins, and demand-supply dynamics cause 1-3 Rs/kg variations. Patna typically has lowest prices due to better connectivity and higher competition among dealers.
Answer: It depends on structural design. Typically:
Always follow your structural engineer's specifications.
Answer: For a 1500 sq ft 3 BHK in Bihar, expect 6-9 tonnes of TMT bars. At current rates (Rs 60-65/kg), budget Rs 3.6-5.7 lakhs. Add 5-10% contingency for price fluctuations.
Answer: Yes, especially for bulk orders (3+ tonnes). Typical negotiation room is 2-5% off listed prices. Cash payments sometimes fetch additional 1-2% discount.
Answer: Both have 500 MPa yield strength, but 'D' (ductile) grade has higher elongation (16% vs 12%). This makes Fe 500D better for earthquake resistance. Recommended for all construction in Bihar (seismic Zone IV).
Answer: Bihar prices are generally 2-4 Rs/kg higher than Gujarat/Maharashtra (near steel plants) but 1-2 Rs/kg lower than Northeast states. Transportation from plants in Odisha, Jharkhand, and West Bengal affects final costs.
Answer: Prices can change daily based on international steel markets, rupee-dollar exchange rates, and domestic demand. Major revisions typically happen weekly. Lock prices with dealers for large orders.
TMT bar prices in Bihar vary by brand, grade, and location, with current rates ranging from Rs 58-65 per kg depending on these factors. For a typical 3 BHK home, expect to spend Rs 3.6-5.7 lakhs on TMT bars. Key takeaways:
