Deflection example
A simply supported HEM 180 spanning 4 m with a 10 kN point load at midspan deflects 0.85 mm (E = 210 GPa, Ix = 7,483 cm⁴). The L/360 serviceability limit for this span is 11.1 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEM 180 weigh?
HEM 180 weighs 88.9 kg per meter. A standard 6 m bar weighs 533.4 kg and a 12 m bar 1,066.8 kg. The weight follows from the cross-section area of 113.3 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEM 180?
HEM 180 is 200 mm tall and 186 mm wide, with a web thickness of 14.5 mm, a flange thickness of 24 mm, and a root radius of 15 mm, per EN 10365 (DIN 1025-4).
What is the moment of inertia of HEM 180?
About the strong axis, Ix = 7,483 cm⁴ with a section modulus Wx = 748 cm³. About the weak axis, Iy = 2,580 cm⁴ and Wy = 277 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEM 180 or HEM 200 — what does one size up change?
HEM 200 is about 16% heavier (103 vs 88.9 kg/m) but about 42% stiffer (Ix 10,640 vs 7,483 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
