HEA 100 — Dimensions, Weight & Section Properties
HEA wide-flange beam per EN 10365 (DIN 1025-3)
HEA 100 is a HEA wide-flange beam per EN 10365 (DIN 1025-3), 96 mm tall and 100 mm wide, weighing 16.7 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 HEA 100 spanning 2 m with a 10 kN point load at midspan deflects 2.27 mm (E = 210 GPa, Ix = 349 cm⁴). The L/360 serviceability limit for this span is 5.6 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEA 100 weigh?
HEA 100 weighs 16.7 kg per meter. A standard 6 m bar weighs 100.2 kg and a 12 m bar 200.4 kg. The weight follows from the cross-section area of 21.2 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEA 100?
HEA 100 is 96 mm tall and 100 mm wide, with a web thickness of 5 mm, a flange thickness of 8 mm, and a root radius of 12 mm, per EN 10365 (DIN 1025-3).
What is the moment of inertia of HEA 100?
About the strong axis, Ix = 349 cm⁴ with a section modulus Wx = 72.8 cm³. About the weak axis, Iy = 134 cm⁴ and Wy = 26.8 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEA 100 or HEA 120 — what does one size up change?
HEA 120 is about 19% heavier (19.9 vs 16.7 kg/m) but about 74% stiffer (Ix 606 vs 349 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
