A delivered bar may differ from these nominal values within the rolling tolerances of EN 10034; invoicing goes by the mill certificate, not by the table.
HEB 140 weight by length
| Length, m | Mass, kg |
|---|---|
| 1 | 33.7 |
| 2 | 67.4 |
| 3 | 101.1 |

Steel cost is mass times the price per kilogram: at a price C per kg a 12 m bar costs 404.4 × C and a 6 m bar 202.2 × C. Cutting, drilling and painting are priced separately; paint goes by surface area, not by weight.
HEB 140 section properties
| Property | Symbol | Value |
|---|---|---|
| Second moment of area, major axis | Iy | 1509 cm⁴ |
| Elastic section modulus, major axis | Wel,y | 215.6 cm³ |
| Radius of gyration, major axis | iy | 5.92 cm |
| Second moment of area, minor axis | Iz | 549.6 cm⁴ |
| Elastic section modulus, minor axis | Wel,z | 78.52 cm³ |
Iy governs deflection, Wel,y bending stress, iy the slenderness of a strut. Iy / Iz = 2.7: in vertical bending the section is 2.7 times stiffer than sideways.

Frequently asked questions
How much does a 6 m and a 12 m HEB 140 weigh?
HEB 140 weighs 33.7 kg/m, so a 6 m bar is 202.2 kg and a 12 m bar 404.4 kg. Ten 12 m bars come to 4044 kg.
Which is heavier: IPE 140, HEA 140, HEB 140 or UPN 140?
Per metre: HEB 140 — 33.7 kg/m (h 140 mm); HEA 140 — 24.7 kg/m (h 133 mm); UPN 140 — 16 kg/m (h 140 mm); IPE 140 — 12.9 kg/m (h 140 mm). The wide-flange HE sections carry load in both planes and go into columns; IPE is the lighter floor beam for bending in one plane.
What does 140 mean in HEB 140?
The nominal depth in millimetres: HEB 140 is 140 mm deep with a 140 mm flange. The letters give the series: HEB, a standard wide-flange beam.
How many metres of HEB 140 are in a tonne?
29.7 m: 1000 kg / 33.7 kg/m. That is about 4.9 bars of 6 m or 2.5 bars of 12 m.
Does S235 or S355 steel change the weight of HEB 140?
No. The table mass is the cross-section area times the density of steel, 7850 kg/m³: 43 cm² × 0.785 = 33.76 kg/m. The grade to EN 10025-2 sets strength, not density. A real bar differs from nominal only within the rolling tolerances of EN 10034.
