HEB 360 — Dimensions, Weight & Section Properties
HEB wide-flange beam per EN 10365 (DIN 1025-2)
HEB 360 is a HEB wide-flange beam per EN 10365 (DIN 1025-2), 360 mm tall and 300 mm wide, weighing 142 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 360 spanning 7 m with a 10 kN point load at midspan deflects 0.79 mm (E = 210 GPa, Ix = 43,190 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 HEB 360 weigh?
HEB 360 weighs 142 kg per meter. A standard 6 m bar weighs 852 kg and a 12 m bar 1,704 kg. The weight follows from the cross-section area of 181 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEB 360?
HEB 360 is 360 mm tall and 300 mm wide, with a web thickness of 12.5 mm, a flange thickness of 22.5 mm, and a root radius of 27 mm, per EN 10365 (DIN 1025-2).
What is the moment of inertia of HEB 360?
About the strong axis, Ix = 43,190 cm⁴ with a section modulus Wx = 2,400 cm³. About the weak axis, Iy = 10,140 cm⁴ and Wy = 676 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEB 360 or HEB 400 — what does one size up change?
HEB 400 is about 9% heavier (155 vs 142 kg/m) but about 34% stiffer (Ix 57,680 vs 43,190 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
