UPE 100 — Dimensions, Weight & Section Properties
UPE parallel-flange channel per EN 10365 (DIN 1026-2)
UPE 100 is a UPE parallel-flange channel per EN 10365 (DIN 1026-2), 100 mm tall and 55 mm wide, weighing 9.82 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 100 spanning 2 m with a 10 kN point load at midspan deflects 3.83 mm (E = 210 GPa, Ix = 207 cm⁴). The L/360 serviceability limit for this span is 5.6 mm — the profile passes this quick check.

Frequently Asked Questions
How much does UPE 100 weigh?
UPE 100 weighs 9.82 kg per meter. A standard 6 m bar weighs 58.9 kg and a 12 m bar 117.8 kg. The weight follows from the cross-section area of 12.5 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of UPE 100?
UPE 100 is 100 mm tall and 55 mm wide, with a web thickness of 4.5 mm, a flange thickness of 7.5 mm, and a root radius of 10 mm, per EN 10365 (DIN 1026-2).
What is the moment of inertia of UPE 100?
About the strong axis, Ix = 207 cm⁴ with a section modulus Wx = 41.4 cm³. About the weak axis, Iy = 38.3 cm⁴ and Wy = 10.6 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
UPE 100 or UPE 120 — what does one size up change?
UPE 120 is about 23% heavier (12.1 vs 9.82 kg/m) but about 76% stiffer (Ix 364 vs 207 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
