1 × W18x50 @ 6.000 m

Method & assumptions

Mass per piece = m × L ; Total mass = m × L × N ; Tonnes = Total mass / 1000

m = mass per metre (kg/m), L = length (m), N = quantity

Mass per metre is calculated from the gross area and a density of 7850 kg/m³. Rolling tolerances, holes, copes and weld deposits are not included.
