Abstract: A method of making floor plate includes assembling a pair of casting rolls laterally disposed to form a nip, assembling a hot rolling mill downstream of the nip having work rolls with a surface pattern forming the negative of a raised slip-resistant pattern desired in a floor plate, introducing molten metal through at least one metal delivery nozzle to form a casting pool supported on the casting rolls above the nip; counter rotating the casting rolls to form shells on the casting surfaces of the casting rolls to cast metal strip of less than 2.2 mm thickness downwardly from the nip, and delivering the cast metal strip to and through the hot rolling mill to form by the negative of the slip-resistant pattern on the work rolls a raised slip-resistant pattern of between 0.3 and 0.7 mm in height in a floor plate of less than 1.7 mm thickness.
