Deflection example
A simply supported HEM 260 spanning 6 m with a 10 kN point load at midspan deflects 0.68 mm (E = 210 GPa, Ix = 31,310 cm⁴). The L/360 serviceability limit for this span is 16.7 mm — the profile passes this quick check.

Frequently Asked Questions
How much does HEM 260 weigh?
HEM 260 weighs 172 kg per meter. A standard 6 m bar weighs 1,032 kg and a 12 m bar 2,064 kg. The weight follows from the cross-section area of 219.6 cm² multiplied by the steel density of 7,850 kg/m³.
What are the dimensions of HEM 260?
HEM 260 is 290 mm tall and 268 mm wide, with a web thickness of 18 mm, a flange thickness of 32.5 mm, and a root radius of 24 mm, per EN 10365 (DIN 1025-4).
What is the moment of inertia of HEM 260?
About the strong axis, Ix = 31,310 cm⁴ with a section modulus Wx = 2,159 cm³. About the weak axis, Iy = 10,450 cm⁴ and Wy = 780 cm³. Use the beam deflection calculator to turn these into deflection and stress for your span and load.
HEM 260 or HEM 280 — what does one size up change?
HEM 280 is about 10% heavier (189 vs 172 kg/m) but about 26% stiffer (Ix 39,550 vs 31,310 cm⁴). Going one size up is usually the cheapest way to cut deflection, because stiffness grows much faster than weight.
