Kamdhenu TMT Bar Weight Chart — Bundle Weight and Pieces
The Kamdhenu TMT bar weight chart details the official IS 1786 compliant weight per metre and the standard bundle weight. A standard bundle of 8mm Kamdhenu sariya contains 12 pieces and weighs approximately 56.88 kg.
- Kamdhenu Nxt features an advanced double-rib pattern for superior concrete bonding
- Retail purchases are heavily calculated by standard "Pieces per Bundle"
- All bars are manufactured to standard 12-metre lengths
Because Kamdhenu operates one of India's largest franchisee manufacturing networks, their TMT bars (especially Kamdhenu Nxt) are extremely popular among local contractors and individual home builders. Unlike large industrial orders placed in metric tonnes, retail market steel is often ordered "by the bundle". Understanding the exact Kamdhenu TMT bar weight chart and bundle configuration prevents you from overpaying or receiving short deliveries.
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)
Kamdhenu Nxt TMT Bar Weight Chart
This chart provides the theoretical kg/m weight alongside the standard retail packing configuration for Kamdhenu sariya.
| Diameter (mm) | Weight per Metre (kg/m) | Standard Pieces per Bundle | Approx. Bundle Weight (kg) |
|---|---|---|---|
| 8 | 0.395 | 12 | 56.88 |
| 10 | 0.617 | 7 | 51.83 |
| 12 | 0.888 | 5 | 53.28 |
| 16 | 1.580 | 3 | 56.88 |
| 20 | 2.466 | 2 | 59.18 |
| 25 | 3.853 | 1 | 46.24 |
Tolerance on mass: ±7% for 8–10mm, ±5% for 12–16mm, and ±3% for 20mm and above, as per IS 1786:2008. Note: Standard pieces per bundle may vary slightly depending on regional packing practices.
Worked Example: Ordering Column Stirrups
A local contractor is casting RCC columns for a two-story house. The engineer's material takeoff specifies a requirement of 65 full lengths (12 meters each) of 10mm Kamdhenu Nxt TMT bars to cut and bend into stirrups (rings).
First, check the bundle configuration: 10mm Kamdhenu comes in bundles of 7 pieces.
Calculate required bundles: 65 pieces ÷ 7 pieces/bundle = 9.28 bundles.
The contractor must round up and order 10 bundles from the local hardware dealer. To verify the delivery weight upon arrival:
10 bundles × 51.83 kg per bundle = 518.3 kg total weight.
The contractor can weigh the delivery at the site to ensure it falls within the acceptable BIS tolerance range, guaranteeing they are receiving high-quality, genuine steel.

Frequently Asked Questions
How many pieces are in a Kamdhenu 8mm bundle?
A standard Kamdhenu 8mm TMT bar bundle usually contains 12 pieces of 12-meter lengths. Since each 8mm piece weighs about 4.74 kg, the total theoretical weight of the bundle is approximately 56.88 kg.
Kamdhenu sariya ka rate aur weight kaise check karein?
Kamdhenu sariya ka weight check karne ke liye D² ÷ 162.27 formula use karein (jaise 10mm ka 0.617 kg/m). Dealer se bundle weight ki parchi (weigh slip) lein aur theoretical weight se match karein. Rate hamesha per kg ya per tonne mein hota hai, jisko total weight se multiply karke final price nikalta hai.
Is Kamdhenu Nxt Fe 500 or 550?
Kamdhenu Nxt is generally manufactured in the Fe 500D and Fe 550D grades. The "D" stands for high ductility, which offers superior resistance during earthquakes, making it highly recommended for residential and commercial RCC structures.
