UPE 80 — Dimensions, Weight & Section Properties
UPE parallel-flange channel per EN 10365 (DIN 1026-2)
UPE 80 is a UPE parallel-flange channel per EN 10365 (DIN 1026-2), 80 mm tall and 50 mm wide, weighing 7.9 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 UPE 80 spanning 2 m with a 10 kN point load at midspan deflects 7.42 mm (E = 210 GPa, Ix = 107 cm⁴). The L/360 serviceability limit for this span is 5.6 mm — the profile does NOT pass this quick check.

Frequently Asked Questions
How much does UPE 80 weigh?
UPE 80 weighs 7.9 kg per meter. A standard 6 m bar weighs 47.4 kg and a 12 m bar 94.8 kg. The weight follows from the cross-section area of 10.1 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of UPE 80?
UPE 80 is 80 mm tall and 50 mm wide, with a web thickness of 4 mm, a flange thickness of 7 mm, and a root radius of 10 mm, per EN 10365 (DIN 1026-2).
What is the moment of inertia of UPE 80?
About the strong axis, Ix = 107 cm⁴ with a section modulus Wx = 26.8 cm³. About the weak axis, Iy = 25.5 cm⁴ and Wy = 8.01 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
UPE 80 or UPE 100 — what does one size up change?
UPE 100 is about 24% heavier (9.82 vs 7.9 kg/m) but about 93% stiffer (Ix 207 vs 107 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
