HEA 550 — Dimensions, Weight & Section Properties
HEA wide-flange beam per EN 10365 (DIN 1025-3)
HEA 550 is a HEA wide-flange beam per EN 10365 (DIN 1025-3), 540 mm tall and 300 mm wide, weighing 166 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 550 spanning 11 m with a 10 kN point load at midspan deflects 1.18 mm (E = 210 GPa, Ix = 111,900 cm⁴). The L/360 serviceability limit for this span is 30.6 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEA 550 weigh?
HEA 550 weighs 166 kg per meter. A standard 6 m bar weighs 996 kg and a 12 m bar 1,992 kg. The weight follows from the cross-section area of 212 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEA 550?
HEA 550 is 540 mm tall and 300 mm wide, with a web thickness of 12.5 mm, a flange thickness of 24 mm, and a root radius of 27 mm, per EN 10365 (DIN 1025-3).
What is the moment of inertia of HEA 550?
About the strong axis, Ix = 111,900 cm⁴ with a section modulus Wx = 4,146 cm³. About the weak axis, Iy = 10,820 cm⁴ and Wy = 721 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEA 550 or HEA 600 — what does one size up change?
HEA 600 is about 7% heavier (178 vs 166 kg/m) but about 26% stiffer (Ix 141,200 vs 111,900 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
