How it was calculated
The weight is the section area multiplied by the material density:
kg/m = section area (mm²) × 0.00785. The area comes from side and thickness, minus the rounded corners: for cold-formed tube (EN 10219) the outer radius is 2t up to 6 mm wall, 2.5t up to 10 mm and 3t above; for hot-finished tube (EN 10210) the outer radius is 1.5t.For Square tube 90×90×8, the section area is 24.04 cm², so 1 metre = 24.04 × 0.785 = 18.873 kg.
The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
