Weights are calculated from nominal dimensions at 7.85 g/cm³ and ignore corner and root radii. Producer tables and actual weights differ slightly because of radii and rolling tolerances.
How to use this chart. Multiply kg/m by the length and number of pieces to estimate weight. Steel is usually billed by weight — agree whether billing is on actual (weighbridge) or theoretical weight before ordering.
