HEA 450 — Dimensions, Weight & Section Properties
HEA wide-flange beam per EN 10365 (DIN 1025-3)
HEA 450 is a HEA wide-flange beam per EN 10365 (DIN 1025-3), 440 mm tall and 300 mm wide, weighing 140 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 450 spanning 9 m with a 10 kN point load at midspan deflects 1.13 mm (E = 210 GPa, Ix = 63,720 cm⁴). The L/360 serviceability limit for this span is 25 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEA 450 weigh?
HEA 450 weighs 140 kg per meter. A standard 6 m bar weighs 840 kg and a 12 m bar 1,680 kg. The weight follows from the cross-section area of 178 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEA 450?
HEA 450 is 440 mm tall and 300 mm wide, with a web thickness of 11.5 mm, a flange thickness of 21 mm, and a root radius of 27 mm, per EN 10365 (DIN 1025-3).
What is the moment of inertia of HEA 450?
About the strong axis, Ix = 63,720 cm⁴ with a section modulus Wx = 2,896 cm³. About the weak axis, Iy = 9,465 cm⁴ and Wy = 631 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEA 450 or HEA 500 — what does one size up change?
HEA 500 is about 11% heavier (155 vs 140 kg/m) but about 36% stiffer (Ix 86,970 vs 63,720 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
