The nearest standard inch thickness is 1 in (25.40 mm, 199.39 kg/m²). Plate this thick is used for heavy base plates, crane girder flanges, machine beds, press frames, pressure vessels and wear parts.
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.
