The nearest standard metric thickness is 5 mm (5.00 mm, 39.25 kg/m²). This thickness is common for base plates of light columns, gussets, brackets, cleats, stiffeners, chequer plate floors and tank shells.
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.
