HEB 180 — Dimensions, Weight & Section Properties
HEB wide-flange beam per EN 10365 (DIN 1025-2)
HEB 180 is a HEB wide-flange beam per EN 10365 (DIN 1025-2), 180 mm tall and 180 mm wide, weighing 51.2 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 180 spanning 4 m with a 10 kN point load at midspan deflects 1.66 mm (E = 210 GPa, Ix = 3,831 cm⁴). The L/360 serviceability limit for this span is 11.1 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEB 180 weigh?
HEB 180 weighs 51.2 kg per meter. A standard 6 m bar weighs 307.2 kg and a 12 m bar 614.4 kg. The weight follows from the cross-section area of 65.3 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEB 180?
HEB 180 is 180 mm tall and 180 mm wide, with a web thickness of 8.5 mm, a flange thickness of 14 mm, and a root radius of 15 mm, per EN 10365 (DIN 1025-2).
What is the moment of inertia of HEB 180?
About the strong axis, Ix = 3,831 cm⁴ with a section modulus Wx = 426 cm³. About the weak axis, Iy = 1,363 cm⁴ and Wy = 151 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEB 180 or HEB 200 — what does one size up change?
HEB 200 is about 20% heavier (61.3 vs 51.2 kg/m) but about 49% stiffer (Ix 5,696 vs 3,831 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
