Deflection example
A simply supported UPN 260 spanning 5 m with a 10 kN point load at midspan deflects 2.57 mm (E = 210 GPa, Ix = 4,820 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 260 weigh?
UPN 260 weighs 37.9 kg per meter. A standard 6 m bar weighs 227.4 kg and a 12 m bar 454.8 kg. The weight follows from the cross-section area of 48.3 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of UPN 260?
UPN 260 is 260 mm tall and 90 mm wide, with a web thickness of 10 mm, a flange thickness of 14 mm, and a root radius of 14 mm, per DIN 1026-1.
What is the moment of inertia of UPN 260?
About the strong axis, Ix = 4,820 cm⁴ with a section modulus Wx = 371 cm³. About the weak axis, Iy = 317 cm⁴ and Wy = 47.7 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
UPN 260 or UPN 280 — what does one size up change?
UPN 280 is about 10% heavier (41.8 vs 37.9 kg/m) but about 30% stiffer (Ix 6,280 vs 4,820 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
