Standard weight per bar and in total
Method
INP weight per metre is read from DIN 1025-1. An INP has tapered flanges and is heavier than the IPE of the same height.
The density of steel is 7.85 g/cm³ (7850 kg/m³) throughout. A number is rounded once, when shown; the table below and the calculator above are the same computation.
The "standard weight" is the nominal weight by table or formula. The "mill weight" is what that mill states for its own length; once you pick a mill, the calculation and the amount use it.
Reference table
Common sizes, by the same computation as the calculator.
| Size | kg per metre | kg per 12 m length |
|---|---|---|
| 8 | 5.94 | 71.28 |
| 10 | 8.34 | 100.08 |
| 12 | 11.1 | 133.2 |
| 14 | 14.3 | 171.6 |
| 16 | 17.9 | 214.8 |
| 18 | 21.9 | 262.8 |
| 20 | 26.2 | 314.4 |
| 22 | 31.1 | 373.2 |
| 24 | 36.2 | 434.4 |
| 26 | 41.9 | 502.8 |

INP size 16 weighs 17.9 kg per metre, and a 12 m length weighs 214.8 kg. Basis: Standard table DIN 1025-1.
For INP size 16, one tonne is 4.66 lengths of 12 m, that is 5 whole lengths (1,074 kg). For any other size use the count-from-weight mode.
The standard weight is the nominal weight by table or formula, the same for every mill. The mill weight is what each mill states for its own length. Pick a mill and its weight and today's price become the basis of the amount.
Pick a mill to see the amount at today's price, then use "Add to cart" or "Proforma". There is no online payment; an Ahantime expert calls to complete the purchase.
