HEA 360 — Dimensions, Weight & Section Properties
HEA wide-flange beam per EN 10365 (DIN 1025-3)
HEA 360 is a HEA wide-flange beam per EN 10365 (DIN 1025-3), 350 mm tall and 300 mm wide, weighing 112 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 360 spanning 7 m with a 10 kN point load at midspan deflects 1.03 mm (E = 210 GPa, Ix = 33,090 cm⁴). The L/360 serviceability limit for this span is 19.4 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEA 360 weigh?
HEA 360 weighs 112 kg per meter. A standard 6 m bar weighs 672 kg and a 12 m bar 1,344 kg. The weight follows from the cross-section area of 143 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEA 360?
HEA 360 is 350 mm tall and 300 mm wide, with a web thickness of 10 mm, a flange thickness of 17.5 mm, and a root radius of 27 mm, per EN 10365 (DIN 1025-3).
What is the moment of inertia of HEA 360?
About the strong axis, Ix = 33,090 cm⁴ with a section modulus Wx = 1,891 cm³. About the weak axis, Iy = 7,887 cm⁴ and Wy = 526 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEA 360 or HEA 400 — what does one size up change?
HEA 400 is about 12% heavier (125 vs 112 kg/m) but about 36% stiffer (Ix 45,070 vs 33,090 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
