IPE 450 — Dimensions, Weight & Section Properties
IPE I-beam per EN 10365 (DIN 1025-5)
IPE 450 is a IPE I-beam per EN 10365 (DIN 1025-5), 450 mm tall and 190 mm wide, weighing 77.6 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 450 spanning 9 m with a 10 kN point load at midspan deflects 2.14 mm (E = 210 GPa, Ix = 33,740 cm⁴). The L/360 serviceability limit for this span is 25 mm — the profile passes this quick check.

Frequently Asked Questions
How much does IPE 450 weigh?
IPE 450 weighs 77.6 kg per meter. A standard 6 m bar weighs 465.6 kg and a 12 m bar 931.2 kg. The weight follows from the cross-section area of 98.8 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of IPE 450?
IPE 450 is 450 mm tall and 190 mm wide, with a web thickness of 9.4 mm, a flange thickness of 14.6 mm, and a root radius of 21 mm, per EN 10365 (DIN 1025-5).
What is the moment of inertia of IPE 450?
About the strong axis, Ix = 33,740 cm⁴ with a section modulus Wx = 1,500 cm³. About the weak axis, Iy = 1,676 cm⁴ and Wy = 176 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
IPE 450 or IPE 500 — what does one size up change?
IPE 500 is about 17% heavier (90.7 vs 77.6 kg/m) but about 43% stiffer (Ix 48,200 vs 33,740 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
