Jindal Panther TMT Bar Weight Chart — Fe 550D Sariya
The Jindal Panther TMT bar weight chart provides the exact kg/m and 12-meter length weights for their Fe 550D sariya, fully compliant with IS 1786 standards. A standard 12mm Jindal Panther bar weighs 0.888 kg/m.
- Jindal Panther primarily manufactures Fe 550D grade rebars
- Bundles are color-coded for quick visual identification of diameters
- All bars follow the strict BIS standard weight formulas
Jindal Panther is widely used across India for residential construction, prized for its high earthquake resistance (Fe 550D ductility). If you are building a home or a commercial project, accurately calculating the Jindal Panther sariya weight ensures your structural engineer's material takeoff translates perfectly into your procurement orders without material shortfalls.
Formula for TMT Bar Weight
Formula: Weight (kg/m) = D² ÷ 162.27
- D
- Nominal diameter of the TMT bar, in millimetres
- 162.27
- Constant derived from π/4 × density of steel (7850 kg/m³)
Jindal Panther TMT Bar Weight Chart (Fe 550D)
This chart provides the theoretical weight multipliers required to convert running meters of Jindal Panther sariya into metric tonnes.
| Diameter (mm) | Cross-Sectional Area (mm²) | Weight per Metre (kg/m) | Weight per 12m Bar (kg) |
|---|---|---|---|
| 8 | 50.3 | 0.395 | 4.74 |
| 10 | 78.6 | 0.617 | 7.40 |
| 12 | 113.1 | 0.888 | 10.66 |
| 16 | 201.1 | 1.580 | 18.96 |
| 20 | 314.2 | 2.466 | 29.59 |
| 25 | 490.9 | 3.853 | 46.24 |
| 28 | 615.8 | 4.834 | 58.01 |
| 32 | 804.2 | 6.313 | 75.76 |
Tolerance on mass: ±7% for 8–10mm, ±5% for 12–16mm, and ±3% for 20mm and above, as per IS 1786:2008.
Worked Example: Residential Slab Reinforcement
A residential builder is casting a roof slab and requires 12mm Jindal Panther rebars. The structural drawings estimate a requirement of 350 full lengths (12 meters each).
First, lookup the unit weight: 12mm bar = 0.888 kg/m.
Calculate the total length: 350 pieces × 12m = 4,200 metres.
Total weight calculation: 4,200m × 0.888 kg/m = 3,729.6 kg.
The builder needs to procure approximately 3.73 tonnes of 12mm Jindal Panther sariya. By matching the weight on the weighbridge against this theoretical standard, the builder can ensure they are receiving genuine IS-compliant steel.

Frequently Asked Questions
What is the weight of a Jindal Panther 12mm bar?
A single 12-meter length of 12mm Jindal Panther TMT bar weighs 10.66 kg. Its weight per meter is 0.888 kg/m, exactly matching the IS 1786 standard formula of D²/162.27.
How to check original Jindal Panther TMT?
Genuine Jindal Panther rebars feature a distinct, uniform rib pattern and have the brand name "Jindal Panther Fe 550D" repeatedly embossed along the length of every bar. You can also verify the authenticity by checking if a sample's per-meter weight falls within the strict ±5% BIS tolerance limits.
What is the bundle weight of 8mm Jindal sariya?
An 8mm Jindal Panther sariya weighs 4.74 kg per 12m piece. Since standard 8mm bundles usually contain 10 to 12 pieces (varying by exact dealer packing), a 10-piece bundle will weigh approximately 47.4 kg.
Jindal Panther sariya ka weight kaise nikale?
Jindal Panther sariya ka weight nikalne ke liye D² ÷ 162.27 formula use karein, jahan D bar ki diameter millimetres mein hai. 12mm ke liye: 12 × 12 ÷ 162.27 = 0.888 kg/m. Isko 12 se multiply karein toh ek full length bar ka weight 10.66 kg aata hai. Yahi IS 1786:2008 ka standard weight hai.
