IPE 100 beam: weight per metre and dimensions
IPE 100 weighs 8.1 kg per metre. A 6 m bar is 48.6 kg, a 12 m bar 97.2 kg, and a tonne is about 123 m of this section. Nominal values to EN 10365: depth 100 mm, flange width 55 mm.

IPE 100 dimensions
| Dimension | Symbol | Value |
|---|---|---|
| Depth | h | 100 mm |
| Flange width | b | 55 mm |
| Web thickness | tw | 4.1 mm |
| Flange thickness | tf | 5.7 mm |

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.
IPE 100 weight by length
| Length, m | Mass, kg |
|---|---|
| 1 | 8.1 |
| 2 | 16.2 |
| 3 | 24.3 |

Steel cost is mass times the price per kilogram: at a price C per kg a 12 m bar costs 97.2 × C and a 6 m bar 48.6 × C. Cutting, drilling and painting are priced separately; paint goes by surface area, not by weight.
IPE 100 section properties
| Property | Symbol | Value |
|---|---|---|
| Second moment of area, major axis | Iy | 171 cm⁴ |
| Elastic section modulus, major axis | Wel,y | 34.2 cm³ |
| Radius of gyration, major axis | iy | 4.07 cm |
| Second moment of area, minor axis | Iz | 15.91 cm⁴ |
| Elastic section modulus, minor axis | Wel,z | 5.788 cm³ |
Iy governs deflection, Wel,y bending stress, iy the slenderness of a strut. Iy / Iz = 10.7: in vertical bending the section is 10.7 times stiffer than sideways.

Frequently asked questions
How much does a 6 m and a 12 m IPE 100 weigh?
IPE 100 weighs 8.1 kg/m, so a 6 m bar is 48.6 kg and a 12 m bar 97.2 kg. Ten 12 m bars come to 972 kg.
Which is heavier: IPE 100, HEA 100, HEB 100 or UPN 100?
Per metre: HEB 100 — 20.4 kg/m (h 100 mm); HEA 100 — 16.7 kg/m (h 96 mm); UPN 100 — 10.6 kg/m (h 100 mm); IPE 100 — 8.1 kg/m (h 100 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 100 mean in IPE 100?
The nominal depth in millimetres: IPE 100 is 100 mm deep with a 55 mm flange. The letters give the series: IPE, an I-beam with narrow parallel flanges.
How many metres of IPE 100 are in a tonne?
123 m: 1000 kg / 8.1 kg/m. That is about 20.6 bars of 6 m or 10.3 bars of 12 m.
Does S235 or S355 steel change the weight of IPE 100?
No. The table mass is the cross-section area times the density of steel, 7850 kg/m³: 10.3 cm² × 0.785 = 8.09 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.
