Deflection example
A simply supported HEB 550 spanning 11 m with a 10 kN point load at midspan deflects 0.97 mm (E = 210 GPa, Ix = 136,700 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 HEB 550 weigh?
HEB 550 weighs 199 kg per meter. A standard 6 m bar weighs 1,194 kg and a 12 m bar 2,388 kg. The weight follows from the cross-section area of 254 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEB 550?
HEB 550 is 550 mm tall and 300 mm wide, with a web thickness of 15 mm, a flange thickness of 29 mm, and a root radius of 27 mm, per EN 10365 (DIN 1025-2).
What is the moment of inertia of HEB 550?
About the strong axis, Ix = 136,700 cm⁴ with a section modulus Wx = 4,971 cm³. About the weak axis, Iy = 13,080 cm⁴ and Wy = 872 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEB 550 or HEB 600 — what does one size up change?
HEB 600 is about 7% heavier (212 vs 199 kg/m) but about 25% stiffer (Ix 171,000 vs 136,700 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
