HEB 100 — Dimensions, Weight & Section Properties
HEB wide-flange beam per EN 10365 (DIN 1025-2)
HEB 100 is a HEB wide-flange beam per EN 10365 (DIN 1025-2), 100 mm tall and 100 mm wide, weighing 20.4 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 100 spanning 2 m with a 10 kN point load at midspan deflects 1.76 mm (E = 210 GPa, Ix = 450 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 HEB 100 weigh?
HEB 100 weighs 20.4 kg per meter. A standard 6 m bar weighs 122.4 kg and a 12 m bar 244.8 kg. The weight follows from the cross-section area of 26 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEB 100?
HEB 100 is 100 mm tall and 100 mm wide, with a web thickness of 6 mm, a flange thickness of 10 mm, and a root radius of 12 mm, per EN 10365 (DIN 1025-2).
What is the moment of inertia of HEB 100?
About the strong axis, Ix = 450 cm⁴ with a section modulus Wx = 89.9 cm³. About the weak axis, Iy = 167 cm⁴ and Wy = 33.5 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEB 100 or HEB 120 — what does one size up change?
HEB 120 is about 31% heavier (26.7 vs 20.4 kg/m) but about 92% stiffer (Ix 864 vs 450 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
