Deflection example
A simply supported HEB 140 spanning 3 m with a 10 kN point load at midspan deflects 1.78 mm (E = 210 GPa, Ix = 1,509 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 HEB 140 weigh?
HEB 140 weighs 33.7 kg per meter. A standard 6 m bar weighs 202.2 kg and a 12 m bar 404.4 kg. The weight follows from the cross-section area of 43 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEB 140?
HEB 140 is 140 mm tall and 140 mm wide, with a web thickness of 7 mm, a flange thickness of 12 mm, and a root radius of 12 mm, per EN 10365 (DIN 1025-2).
What is the moment of inertia of HEB 140?
About the strong axis, Ix = 1,509 cm⁴ with a section modulus Wx = 216 cm³. About the weak axis, Iy = 550 cm⁴ and Wy = 78.5 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEB 140 or HEB 160 — what does one size up change?
HEB 160 is about 26% heavier (42.6 vs 33.7 kg/m) but about 65% stiffer (Ix 2,492 vs 1,509 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
