IPN 360 — Dimensions, Weight & Section Properties
IPN I-beam per EN 10365 (DIN 1025-1)
IPN 360 is a IPN I-beam per EN 10365 (DIN 1025-1), 360 mm tall and 143 mm wide, weighing 76.1 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 360 spanning 7 m with a 10 kN point load at midspan deflects 1.74 mm (E = 210 GPa, Ix = 19,610 cm⁴). The L/360 serviceability limit for this span is 19.4 mm — the profile passes this quick check.

Frequently Asked Questions
How much does IPN 360 weigh?
IPN 360 weighs 76.1 kg per meter. A standard 6 m bar weighs 456.6 kg and a 12 m bar 913.2 kg. The weight follows from the cross-section area of 97 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of IPN 360?
IPN 360 is 360 mm tall and 143 mm wide, with a web thickness of 13 mm, a flange thickness of 19.5 mm, and a root radius of 13 mm, per EN 10365 (DIN 1025-1).
What is the moment of inertia of IPN 360?
About the strong axis, Ix = 19,610 cm⁴ with a section modulus Wx = 1,090 cm³. About the weak axis, Iy = 818 cm⁴ and Wy = 114 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
IPN 360 or IPN 380 — what does one size up change?
IPN 380 is about 10% heavier (84 vs 76.1 kg/m) but about 22% stiffer (Ix 24,010 vs 19,610 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
