Deflection example
A simply supported HEM 220 spanning 5 m with a 10 kN point load at midspan deflects 0.85 mm (E = 210 GPa, Ix = 14,600 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 HEM 220 weigh?
HEM 220 weighs 117 kg per meter. A standard 6 m bar weighs 702 kg and a 12 m bar 1,404 kg. The weight follows from the cross-section area of 149.4 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEM 220?
HEM 220 is 240 mm tall and 226 mm wide, with a web thickness of 15.5 mm, a flange thickness of 26 mm, and a root radius of 18 mm, per EN 10365 (DIN 1025-4).
What is the moment of inertia of HEM 220?
About the strong axis, Ix = 14,600 cm⁴ with a section modulus Wx = 1,217 cm³. About the weak axis, Iy = 5,012 cm⁴ and Wy = 444 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEM 220 or HEM 240 — what does one size up change?
HEM 240 is about 34% heavier (157 vs 117 kg/m) but about 66% stiffer (Ix 24,290 vs 14,600 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
