Deflection example
A simply supported HEB 240 spanning 5 m with a 10 kN point load at midspan deflects 1.1 mm (E = 210 GPa, Ix = 11,260 cm⁴). The L/360 serviceability limit for this span is 13.9 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEB 240 weigh?
HEB 240 weighs 83.2 kg per meter. A standard 6 m bar weighs 499.2 kg and a 12 m bar 998.4 kg. The weight follows from the cross-section area of 106 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEB 240?
HEB 240 is 240 mm tall and 240 mm wide, with a web thickness of 10 mm, a flange thickness of 17 mm, and a root radius of 21 mm, per EN 10365 (DIN 1025-2).
What is the moment of inertia of HEB 240?
About the strong axis, Ix = 11,260 cm⁴ with a section modulus Wx = 938 cm³. About the weak axis, Iy = 3,923 cm⁴ and Wy = 327 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEB 240 or HEB 260 — what does one size up change?
HEB 260 is about 12% heavier (93 vs 83.2 kg/m) but about 33% stiffer (Ix 14,920 vs 11,260 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
