Quick answer: MS angle, channel, and beam weight depends on size and section, not just length. Ordering by length alone is how buyers end up short on tonnage or overpaying for excess steel. Below are standard weight-per-metre figures for the sizes most used in Gujarat fabrication and construction work, plus how to convert that into a purchase order that matches what your site actually needs.
Why Weight Matters More Than Length
Structural steel is bought and priced by weight, not by the metre. Two 6-metre angles in different thicknesses can differ in weight by 30% or more. If your PO specifies length and grade but not the exact section weight, you’re relying on the supplier to fill in the gap, and that’s where under-delivery and billing disputes start.
MS Angle Weight Chart (Equal Angles)
| Size (mm) | Thickness (mm) | Weight (kg/m) |
|---|---|---|
| 25 x 25 | 3 | 1.12 |
| 40 x 40 | 5 | 2.95 |
| 50 x 50 | 6 | 4.5 |
| 65 x 65 | 6 | 5.9 |
| 75 x 75 | 8 | 8.9 |
| 100 x 100 | 10 | 14.9 |
MS Channel Weight Chart
| Channel Size | Weight (kg/m) |
|---|---|
| ISMC 75 | 7.14 |
| ISMC 100 | 9.56 |
| ISMC 125 | 13.1 |
| ISMC 150 | 16.4 |
| ISMC 200 | 22.3 |
| ISMC 250 | 30.6 |
MS Beam Weight Chart (ISMB)
| Beam Size | Weight (kg/m) |
|---|---|
| ISMB 100 | 11.5 |
| ISMB 125 | 13.0 |
| ISMB 150 | 15.0 |
| ISMB 200 | 25.4 |
| ISMB 250 | 34.9 |
| ISMB 300 | 44.9 |
Figures are standard IS 808 reference weights. Always confirm the exact weight for your specific heat and mill batch before finalising a large order, since actual rolled tolerance can shift it slightly.
How to Convert This Into an Order
Once you know weight per metre, the order becomes simple maths: total length required × weight per metre = tonnage to order. Round up, not down. Fabricators who round down to save a few kilos on paper usually end up placing a rushed second order mid-project, which costs more than the steel they tried to save.
Common Mistake: Mixing Up Nominal and Actual Weight
Some suppliers quote “nominal” weight based on catalogue tables, while what leaves the yard is the actual rolled weight, which can vary by a few percent. For small orders this barely matters. For orders running into tonnes, that variance changes your final bill. Ask for actual weighbridge slips, not just catalogue figures, on any order above a few tonnes.
Get the Right Section for Your Project
Angles, channels, and beams all serve different structural roles; picking the wrong one because the weight looked similar on paper is a common site-level error. If you’re not sure which section your project needs, send us the load requirement and span, and we’ll confirm the right size before you place the order.
