HEA 180 — Dimensions, Weight & Section Properties
HEA wide-flange beam per EN 10365 (DIN 1025-3)
HEA 180 is a HEA wide-flange beam per EN 10365 (DIN 1025-3), 171 mm tall and 180 mm wide, weighing 35.5 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 180 spanning 3 m with a 10 kN point load at midspan deflects 1.07 mm (E = 210 GPa, Ix = 2,510 cm⁴). The L/360 serviceability limit for this span is 8.3 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEA 180 weigh?
HEA 180 weighs 35.5 kg per meter. A standard 6 m bar weighs 213 kg and a 12 m bar 426 kg. The weight follows from the cross-section area of 45.3 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEA 180?
HEA 180 is 171 mm tall and 180 mm wide, with a web thickness of 6 mm, a flange thickness of 9.5 mm, and a root radius of 15 mm, per EN 10365 (DIN 1025-3).
What is the moment of inertia of HEA 180?
About the strong axis, Ix = 2,510 cm⁴ with a section modulus Wx = 294 cm³. About the weak axis, Iy = 925 cm⁴ and Wy = 103 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEA 180 or HEA 200 — what does one size up change?
HEA 200 is about 19% heavier (42.3 vs 35.5 kg/m) but about 47% stiffer (Ix 3,692 vs 2,510 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
