The nearest standard inch thickness is 3/8 in (9.52 mm, 74.77 kg/m²). This thickness is common for column base plates, end plates, splice plates, heavy gussets, machine frames and bridge stiffeners.
Hot-rolled plate is made to a thickness tolerance (EN 10029 in Europe, ASTM A6 in the US). These tolerances allow more over-thickness than under-thickness, so weighbridge weights can come out a little above the theoretical weight.
