Deflection example
A simply supported HEB 450 spanning 9 m with a 10 kN point load at midspan deflects 0.91 mm (E = 210 GPa, Ix = 79,890 cm⁴). The L/360 serviceability limit for this span is 25 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEB 450 weigh?
HEB 450 weighs 171 kg per meter. A standard 6 m bar weighs 1,026 kg and a 12 m bar 2,052 kg. The weight follows from the cross-section area of 218 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEB 450?
HEB 450 is 450 mm tall and 300 mm wide, with a web thickness of 14 mm, a flange thickness of 26 mm, and a root radius of 27 mm, per EN 10365 (DIN 1025-2).
What is the moment of inertia of HEB 450?
About the strong axis, Ix = 79,890 cm⁴ with a section modulus Wx = 3,551 cm³. About the weak axis, Iy = 11,720 cm⁴ and Wy = 781 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEB 450 or HEB 500 — what does one size up change?
HEB 500 is about 9% heavier (187 vs 171 kg/m) but about 34% stiffer (Ix 107,200 vs 79,890 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
