IPN 260 — Dimensions, Weight & Section Properties
IPN I-beam per EN 10365 (DIN 1025-1)
IPN 260 is a IPN I-beam per EN 10365 (DIN 1025-1), 260 mm tall and 113 mm wide, weighing 41.9 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 260 spanning 5 m with a 10 kN point load at midspan deflects 2.16 mm (E = 210 GPa, Ix = 5,740 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 260 weigh?
IPN 260 weighs 41.9 kg per meter. A standard 6 m bar weighs 251.4 kg and a 12 m bar 502.8 kg. The weight follows from the cross-section area of 53.3 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of IPN 260?
IPN 260 is 260 mm tall and 113 mm wide, with a web thickness of 9.4 mm, a flange thickness of 14.1 mm, and a root radius of 9.4 mm, per EN 10365 (DIN 1025-1).
What is the moment of inertia of IPN 260?
About the strong axis, Ix = 5,740 cm⁴ with a section modulus Wx = 442 cm³. About the weak axis, Iy = 288 cm⁴ and Wy = 51 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
IPN 260 or IPN 280 — what does one size up change?
IPN 280 is about 14% heavier (47.9 vs 41.9 kg/m) but about 32% stiffer (Ix 7,590 vs 5,740 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
