Deflection example
A simply supported HEA 140 spanning 3 m with a 10 kN point load at midspan deflects 2.59 mm (E = 210 GPa, Ix = 1,033 cm⁴). The L/360 serviceability limit for this span is 8.3 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEA 140 weigh?
HEA 140 weighs 24.7 kg per meter. A standard 6 m bar weighs 148.2 kg and a 12 m bar 296.4 kg. The weight follows from the cross-section area of 31.4 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEA 140?
HEA 140 is 133 mm tall and 140 mm wide, with a web thickness of 5.5 mm, a flange thickness of 8.5 mm, and a root radius of 12 mm, per EN 10365 (DIN 1025-3).
What is the moment of inertia of HEA 140?
About the strong axis, Ix = 1,033 cm⁴ with a section modulus Wx = 155 cm³. About the weak axis, Iy = 389 cm⁴ and Wy = 55.6 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEA 140 or HEA 160 — what does one size up change?
HEA 160 is about 23% heavier (30.4 vs 24.7 kg/m) but about 62% stiffer (Ix 1,673 vs 1,033 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
