IPE 550 — Dimensions, Weight & Section Properties
IPE I-beam per EN 10365 (DIN 1025-5)
IPE 550 is a IPE I-beam per EN 10365 (DIN 1025-5), 550 mm tall and 210 mm wide, weighing 106 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 IPE 550 spanning 11 m with a 10 kN point load at midspan deflects 1.97 mm (E = 210 GPa, Ix = 67,120 cm⁴). The L/360 serviceability limit for this span is 30.6 mm — the profile passes this quick check.

Frequently Asked Questions
How much does IPE 550 weigh?
IPE 550 weighs 106 kg per meter. A standard 6 m bar weighs 636 kg and a 12 m bar 1,272 kg. The weight follows from the cross-section area of 134 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of IPE 550?
IPE 550 is 550 mm tall and 210 mm wide, with a web thickness of 11.1 mm, a flange thickness of 17.2 mm, and a root radius of 24 mm, per EN 10365 (DIN 1025-5).
What is the moment of inertia of IPE 550?
About the strong axis, Ix = 67,120 cm⁴ with a section modulus Wx = 2,441 cm³. About the weak axis, Iy = 2,668 cm⁴ and Wy = 254 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
IPE 550 or IPE 600 — what does one size up change?
IPE 600 is about 15% heavier (122 vs 106 kg/m) but about 37% stiffer (Ix 92,080 vs 67,120 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
