IPN 500 — Dimensions, Weight & Section Properties
IPN I-beam per EN 10365 (DIN 1025-1)
IPN 500 is a IPN I-beam per EN 10365 (DIN 1025-1), 500 mm tall and 185 mm wide, weighing 141 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 IPN 500 spanning 10 m with a 10 kN point load at midspan deflects 1.44 mm (E = 210 GPa, Ix = 68,740 cm⁴). The L/360 serviceability limit for this span is 27.8 mm — the profile passes this quick check.

Frequently Asked Questions
How much does IPN 500 weigh?
IPN 500 weighs 141 kg per meter. A standard 6 m bar weighs 846 kg and a 12 m bar 1,692 kg. The weight follows from the cross-section area of 179 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of IPN 500?
IPN 500 is 500 mm tall and 185 mm wide, with a web thickness of 18 mm, a flange thickness of 27 mm, and a root radius of 18 mm, per EN 10365 (DIN 1025-1).
What is the moment of inertia of IPN 500?
About the strong axis, Ix = 68,740 cm⁴ with a section modulus Wx = 2,750 cm³. About the weak axis, Iy = 2,480 cm⁴ and Wy = 268 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
IPN 500 or IPN 550 — what does one size up change?
IPN 550 is about 18% heavier (166 vs 141 kg/m) but about 44% stiffer (Ix 99,180 vs 68,740 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
