How it was calculated
The weight is the section area multiplied by the material density:
kg/m = section area (mm²) × 0.00785, with the area calculated from width, height and thickness and the corners rounded per EN 10219 (cold-formed) or EN 10210 (hot-finished, outer radius 1.5t).For Rectangular tube 70×40×6, the section area is 10.83 cm², so 1 metre = 10.83 × 0.785 = 8.504 kg.
The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
