Steel weight tables (kg/m)

Theoretical weight tables for the most common steel products: square, rectangular and round tubes, flat bars, angles, square and round bars, sheets and IPE, HEA, HEB, UPN and UPE beams. Weights are calculated with a steel density of 7.85 kg/dm³; actual weight may vary slightly with manufacturing tolerances.

All these products are available at COMARFER in Aïn Harrouda. Send us your sizes and quantities: free quote and free delivery within 24–48 h in the Casablanca region.

Calculation formulas

Weight (kg/m) = steel cross-section (mm²) × 0.00785
Round tube: π × (Ø − t) × t × 0.00785 (t = thickness)
Flat bar: width × thickness × 0.00785 · round bar: 0.00617 × Ø²
Sheet: 7.85 kg/m² per mm of thickness
Square and rectangular tubes: rounded corners per EN 10219. Angles: root radius not counted (difference under 1%).

Frequently Asked Questions

How do I calculate the weight of a square tube?

Multiply the steel cross-section (mm²) by 0.00785 to get kg/m. For a square tube the section is about 4 × t × (side − t), minus the rounded corners. Example: a 40 × 40 × 3 tube weighs 3.30 kg/m, i.e. 19.8 kg per 6 m bar.

How much does a 3000 × 1500 mm sheet weigh?

2 mm: 70.7 kg · 3 mm: 106 kg · 4 mm: 141.3 kg · 5 mm: 176.6 kg · 6 mm: 212 kg · 8 mm: 282.6 kg (theoretical weights, 7.85 kg/m² per mm of thickness).

Are these weights exact?

They are theoretical weights calculated with a density of 7.85 kg/dm³. Actual weight can vary by a few percent with manufacturing tolerances. For an order, ask for a quote: we give you the weight and the price.
