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 400, the section area is 325.78 cm², so 1 metre = 325.78 × 0.785 = 255.736 kg.
The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
