UPE 400 — Dimensions, Weight & Section Properties
UPE parallel-flange channel per EN 10365 (DIN 1026-2)
UPE 400 is a UPE parallel-flange channel per EN 10365 (DIN 1026-2), 400 mm tall and 115 mm wide, weighing 72.2 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 400 spanning 8 m with a 10 kN point load at midspan deflects 2.42 mm (E = 210 GPa, Ix = 20,980 cm⁴). The L/360 serviceability limit for this span is 22.2 mm — the profile passes this quick check.

Frequently Asked Questions
How much does UPE 400 weigh?
UPE 400 weighs 72.2 kg per meter. A standard 6 m bar weighs 433.2 kg and a 12 m bar 866.4 kg. The weight follows from the cross-section area of 91.9 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of UPE 400?
UPE 400 is 400 mm tall and 115 mm wide, with a web thickness of 13.5 mm, a flange thickness of 18 mm, and a root radius of 18 mm, per EN 10365 (DIN 1026-2).
What is the moment of inertia of UPE 400?
About the strong axis, Ix = 20,980 cm⁴ with a section modulus Wx = 1,050 cm³. About the weak axis, Iy = 1,045 cm⁴ and Wy = 123 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
UPE 400 or UPE 360 — what does one size down change?
UPE 360 is about 15% lighter (61.2 vs 72.2 kg/m) but about 29% less stiff (Ix 14,830 vs 20,980 cm⁴). Check deflection before downsizing — stiffness falls much faster than weight.
