How it was calculated

The weight is the section area multiplied by the material density:

kg/m = section area (cm²) × 0.785. For HEA, HEB, HEM and IPE the area is calculated exactly from h, b, tw, tf and the root radius r per EN 10365; for INP, UPN and UPE the manufacturers’ tabulated area is used.

For HEM 340, the section area is 315.83 cm², so 1 metre = 315.83 × 0.785 = 247.925 kg.

The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
