Deflection example
A simply supported UPN 240 spanning 5 m with a 10 kN point load at midspan deflects 3.44 mm (E = 210 GPa, Ix = 3,600 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 UPN 240 weigh?
UPN 240 weighs 33.2 kg per meter. A standard 6 m bar weighs 199.2 kg and a 12 m bar 398.4 kg. The weight follows from the cross-section area of 42.3 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of UPN 240?
UPN 240 is 240 mm tall and 85 mm wide, with a web thickness of 9.5 mm, a flange thickness of 13 mm, and a root radius of 13 mm, per DIN 1026-1.
What is the moment of inertia of UPN 240?
About the strong axis, Ix = 3,600 cm⁴ with a section modulus Wx = 300 cm³. About the weak axis, Iy = 248 cm⁴ and Wy = 39.6 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
UPN 240 or UPN 260 — what does one size up change?
UPN 260 is about 14% heavier (37.9 vs 33.2 kg/m) but about 34% stiffer (Ix 4,820 vs 3,600 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
