IPN 160 — Dimensions, Weight & Section Properties
IPN I-beam per EN 10365 (DIN 1025-1)
IPN 160 is a IPN I-beam per EN 10365 (DIN 1025-1), 160 mm tall and 74 mm wide, weighing 17.9 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 IPN 160 spanning 3 m with a 10 kN point load at midspan deflects 2.86 mm (E = 210 GPa, Ix = 935 cm⁴). The L/360 serviceability limit for this span is 8.3 mm — the profile passes this quick check.

Frequently Asked Questions
How much does IPN 160 weigh?
IPN 160 weighs 17.9 kg per meter. A standard 6 m bar weighs 107.4 kg and a 12 m bar 214.8 kg. The weight follows from the cross-section area of 22.8 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of IPN 160?
IPN 160 is 160 mm tall and 74 mm wide, with a web thickness of 6.3 mm, a flange thickness of 9.5 mm, and a root radius of 6.3 mm, per EN 10365 (DIN 1025-1).
What is the moment of inertia of IPN 160?
About the strong axis, Ix = 935 cm⁴ with a section modulus Wx = 117 cm³. About the weak axis, Iy = 54.7 cm⁴ and Wy = 14.8 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
IPN 160 or IPN 180 — what does one size up change?
IPN 180 is about 22% heavier (21.9 vs 17.9 kg/m) but about 55% stiffer (Ix 1,450 vs 935 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
