HEB 260 — Dimensions, Weight & Section Properties
HEB wide-flange beam per EN 10365 (DIN 1025-2)
HEB 260 is a HEB wide-flange beam per EN 10365 (DIN 1025-2), 260 mm tall and 260 mm wide, weighing 93 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 HEB 260 spanning 5 m with a 10 kN point load at midspan deflects 0.83 mm (E = 210 GPa, Ix = 14,920 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 HEB 260 weigh?
HEB 260 weighs 93 kg per meter. A standard 6 m bar weighs 558 kg and a 12 m bar 1,116 kg. The weight follows from the cross-section area of 118 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEB 260?
HEB 260 is 260 mm tall and 260 mm wide, with a web thickness of 10 mm, a flange thickness of 17.5 mm, and a root radius of 24 mm, per EN 10365 (DIN 1025-2).
What is the moment of inertia of HEB 260?
About the strong axis, Ix = 14,920 cm⁴ with a section modulus Wx = 1,148 cm³. About the weak axis, Iy = 5,135 cm⁴ and Wy = 395 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEB 260 or HEB 280 — what does one size up change?
HEB 280 is about 11% heavier (103 vs 93 kg/m) but about 29% stiffer (Ix 19,270 vs 14,920 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
