IPE 300 — Dimensions, Weight & Section Properties
IPE I-beam per EN 10365 (DIN 1025-5)
IPE 300 is a IPE I-beam per EN 10365 (DIN 1025-5), 300 mm tall and 150 mm wide, weighing 42.2 kg per meter. All dimensions and section properties below are the standard published values used in structural design across Europe.
Typical uses: floor beams, columns, frames, and general steel construction. For a quick strength check, use the deflection example below or open the beam calculator with your own span and load.

Deflection example
A simply supported IPE 300 spanning 6 m with a 10 kN point load at midspan deflects 2.56 mm (E = 210 GPa, Ix = 8,356 cm⁴). The L/360 serviceability limit for this span is 16.7 mm — the profile passes this quick check.

Frequently Asked Questions
How much does IPE 300 weigh?
IPE 300 weighs 42.2 kg per meter. A standard 6 m bar weighs 253.2 kg and a 12 m bar 506.4 kg. The weight follows from the cross-section area of 53.8 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of IPE 300?
IPE 300 is 300 mm tall and 150 mm wide, with a web thickness of 7.1 mm, a flange thickness of 10.7 mm, and a root radius of 15 mm, per EN 10365 (DIN 1025-5).
What is the moment of inertia of IPE 300?
About the strong axis, Ix = 8,356 cm⁴ with a section modulus Wx = 557 cm³. About the weak axis, Iy = 604 cm⁴ and Wy = 80.5 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
IPE 300 or IPE 330 — what does one size up change?
IPE 330 is about 16% heavier (49.1 vs 42.2 kg/m) but about 41% stiffer (Ix 11,770 vs 8,356 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
