HEM 100 — Dimensions, Weight & Section Properties
HEM heavy wide-flange beam per EN 10365 (DIN 1025-4)
HEM 100 is a HEM heavy wide-flange beam per EN 10365 (DIN 1025-4), 120 mm tall and 106 mm wide, weighing 41.8 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 HEM 100 spanning 2 m with a 10 kN point load at midspan deflects 0.69 mm (E = 210 GPa, Ix = 1,143 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 HEM 100 weigh?
HEM 100 weighs 41.8 kg per meter. A standard 6 m bar weighs 250.8 kg and a 12 m bar 501.6 kg. The weight follows from the cross-section area of 53.2 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEM 100?
HEM 100 is 120 mm tall and 106 mm wide, with a web thickness of 12 mm, a flange thickness of 20 mm, and a root radius of 12 mm, per EN 10365 (DIN 1025-4).
What is the moment of inertia of HEM 100?
About the strong axis, Ix = 1,143 cm⁴ with a section modulus Wx = 190 cm³. About the weak axis, Iy = 399 cm⁴ and Wy = 75.3 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEM 100 or HEM 120 — what does one size up change?
HEM 120 is about 25% heavier (52.1 vs 41.8 kg/m) but about 77% stiffer (Ix 2,018 vs 1,143 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
