Deflection example
A simply supported HEM 360 spanning 8 m with a 10 kN point load at midspan deflects 0.6 mm (E = 210 GPa, Ix = 84,870 cm⁴). The L/360 serviceability limit for this span is 22.2 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEM 360 weigh?
HEM 360 weighs 250 kg per meter. A standard 6 m bar weighs 1,500 kg and a 12 m bar 3,000 kg. The weight follows from the cross-section area of 318.8 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEM 360?
HEM 360 is 395 mm tall and 308 mm wide, with a web thickness of 21 mm, a flange thickness of 40 mm, and a root radius of 27 mm, per EN 10365 (DIN 1025-4).
What is the moment of inertia of HEM 360?
About the strong axis, Ix = 84,870 cm⁴ with a section modulus Wx = 4,297 cm³. About the weak axis, Iy = 19,520 cm⁴ and Wy = 1,268 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEM 360 or HEM 400 — what does one size up change?
HEM 400 is about 2% heavier (256 vs 250 kg/m) but about 23% stiffer (Ix 104,100 vs 84,870 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
