IPE 300 dimensions
| Dimension | Symbol | Value |

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 300 weight by length
| Length, m | Mass, kg |
|---|---|
| 1 | 42.2 |
| 2 | 84.4 |
| 3 | 126.6 |
| 4 | 168.8 |

Steel cost is mass times the price per kilogram: at a price C per kg a 12 m bar costs 506.4 × C and a 6 m bar 253.2 × C. Cutting, drilling and painting are priced separately; paint goes by surface area, not by weight.
IPE 300 section properties
| Property | Symbol | Value |
|---|---|---|
| Second moment of area, major axis | Iy | 8356 cm⁴ |
| Elastic section modulus, major axis | Wel,y | 557 cm³ |
| Radius of gyration, major axis | iy | 12.5 cm |
| Second moment of area, minor axis | Iz | 603.7 cm⁴ |
| Elastic section modulus, minor axis | Wel,z | 80.5 cm³ |
Iy governs deflection, Wel,y bending stress, iy the slenderness of a strut. Iy / Iz = 13.8: in vertical bending the section is 13.8 times stiffer than sideways.

Frequently asked questions
How much does a 6 m and a 12 m IPE 300 weigh?
IPE 300 weighs 42.2 kg/m, so a 6 m bar is 253.2 kg and a 12 m bar 506.4 kg. Ten 12 m bars come to 5064 kg.
Which is heavier: IPE 300, HEA 300, HEB 300 or UPN 300?
Per metre: HEB 300 — 117 kg/m (h 300 mm); HEA 300 — 88.3 kg/m (h 290 mm); UPN 300 — 46.2 kg/m (h 300 mm); IPE 300 — 42.2 kg/m (h 300 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 300 mean in IPE 300?
The nominal depth in millimetres: IPE 300 is 300 mm deep with a 150 mm flange. The letters give the series: IPE, an I-beam with narrow parallel flanges.
How many metres of IPE 300 are in a tonne?
23.7 m: 1000 kg / 42.2 kg/m. That is about 3.9 bars of 6 m or 2 bars of 12 m.
Does S235 or S355 steel change the weight of IPE 300?
No. The table mass is the cross-section area times the density of steel, 7850 kg/m³: 53.8 cm² × 0.785 = 42.23 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.
