UPN 200 — Dimensions, Weight & Section Properties
UPN channel per DIN 1026-1
UPN 200 is a UPN channel per DIN 1026-1, 200 mm tall and 75 mm wide, weighing 25.3 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 200 spanning 4 m with a 10 kN point load at midspan deflects 3.32 mm (E = 210 GPa, Ix = 1,910 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 200 weigh?
UPN 200 weighs 25.3 kg per meter. A standard 6 m bar weighs 151.8 kg and a 12 m bar 303.6 kg. The weight follows from the cross-section area of 32.2 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of UPN 200?
UPN 200 is 200 mm tall and 75 mm wide, with a web thickness of 8.5 mm, a flange thickness of 11.5 mm, and a root radius of 11.5 mm, per DIN 1026-1.
What is the moment of inertia of UPN 200?
About the strong axis, Ix = 1,910 cm⁴ with a section modulus Wx = 191 cm³. About the weak axis, Iy = 148 cm⁴ and Wy = 27 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
UPN 200 or UPN 220 — what does one size up change?
UPN 220 is about 16% heavier (29.4 vs 25.3 kg/m) but about 41% stiffer (Ix 2,690 vs 1,910 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
