IPN 240 — Dimensions, Weight & Section Properties
IPN I-beam per EN 10365 (DIN 1025-1)
IPN 240 is a IPN I-beam per EN 10365 (DIN 1025-1), 240 mm tall and 106 mm wide, weighing 36.2 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 IPN 240 spanning 5 m with a 10 kN point load at midspan deflects 2.92 mm (E = 210 GPa, Ix = 4,250 cm⁴). The L/360 serviceability limit for this span is 13.9 mm — the profile passes this quick check.

Frequently Asked Questions
How much does IPN 240 weigh?
IPN 240 weighs 36.2 kg per meter. A standard 6 m bar weighs 217.2 kg and a 12 m bar 434.4 kg. The weight follows from the cross-section area of 46.1 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of IPN 240?
IPN 240 is 240 mm tall and 106 mm wide, with a web thickness of 8.7 mm, a flange thickness of 13.1 mm, and a root radius of 8.7 mm, per EN 10365 (DIN 1025-1).
What is the moment of inertia of IPN 240?
About the strong axis, Ix = 4,250 cm⁴ with a section modulus Wx = 354 cm³. About the weak axis, Iy = 221 cm⁴ and Wy = 41.7 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
IPN 240 or IPN 260 — what does one size up change?
IPN 260 is about 16% heavier (41.9 vs 36.2 kg/m) but about 35% stiffer (Ix 5,740 vs 4,250 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
