Deflection example
A simply supported UPN 220 spanning 4 m with a 10 kN point load at midspan deflects 2.36 mm (E = 210 GPa, Ix = 2,690 cm⁴). The L/360 serviceability limit for this span is 11.1 mm — the profile passes this quick check.

Frequently Asked Questions
How much does UPN 220 weigh?
UPN 220 weighs 29.4 kg per meter. A standard 6 m bar weighs 176.4 kg and a 12 m bar 352.8 kg. The weight follows from the cross-section area of 37.4 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of UPN 220?
UPN 220 is 220 mm tall and 80 mm wide, with a web thickness of 9 mm, a flange thickness of 12.5 mm, and a root radius of 12.5 mm, per DIN 1026-1.
What is the moment of inertia of UPN 220?
About the strong axis, Ix = 2,690 cm⁴ with a section modulus Wx = 245 cm³. About the weak axis, Iy = 197 cm⁴ and Wy = 33.6 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
UPN 220 or UPN 240 — what does one size up change?
UPN 240 is about 13% heavier (33.2 vs 29.4 kg/m) but about 34% stiffer (Ix 3,600 vs 2,690 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
