UPN 140 — Dimensions, Weight & Section Properties
UPN channel per DIN 1026-1
UPN 140 is a UPN channel per DIN 1026-1, 140 mm tall and 60 mm wide, weighing 16 kg per meter. All dimensions and section properties below are the standard published values used in structural design across Europe.
Typical uses: floor beams, columns, frames, and general steel construction. For a quick strength check, use the deflection example below or open the beam calculator with your own span and load.

Deflection example
A simply supported UPN 140 spanning 3 m with a 10 kN point load at midspan deflects 4.43 mm (E = 210 GPa, Ix = 605 cm⁴). The L/360 serviceability limit for this span is 8.3 mm — the profile passes this quick check.

Frequently Asked Questions
How much does UPN 140 weigh?
UPN 140 weighs 16 kg per meter. A standard 6 m bar weighs 96 kg and a 12 m bar 192 kg. The weight follows from the cross-section area of 20.4 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of UPN 140?
UPN 140 is 140 mm tall and 60 mm wide, with a web thickness of 7 mm, a flange thickness of 10 mm, and a root radius of 10 mm, per DIN 1026-1.
What is the moment of inertia of UPN 140?
About the strong axis, Ix = 605 cm⁴ with a section modulus Wx = 86.4 cm³. About the weak axis, Iy = 62.7 cm⁴ and Wy = 14.8 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
UPN 140 or UPN 160 — what does one size up change?
UPN 160 is about 18% heavier (18.8 vs 16 kg/m) but about 53% stiffer (Ix 925 vs 605 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
