Abstract
Floor plates and methods of manufacturing floor plates are presented herein. The method including hot rolling a steel slab in one or more hot rolling passes into a steel coil or plate, annealing the steel coil or plate after the hot rolling into an annealed steel coil or plate, and cold rolling or temper rolling the annealed steel coil or plate into the floor plate in one or more cold rolling or temper rolling passes of a rolling apparatus, wherein the rolling apparatus includes a top roller and a bottom roller and is structured to achieve a desired lug pattern and height with a gauge reduction using either hot-rolled and/or annealed steel.

A method of manufacturing a floor plate, the method comprising:
- cold rolling or temper rolling a hot rolled or annealed steel into the floor plate in one or more cold rolling passes or one or more temper rolling passes of a rolling apparatus, wherein the rolling apparatus comprises a first roller and a second roller and is structured to form a plurality of lugs in the floor plate while achieving a gauge reduction in the floor plate of between 2% and 20%.
A floor plate comprising:
- a base portion comprising a steel plate having a top surface and a bottom surface;
- a plurality of lugs extending from at least one surface of the steel plate, wherein the plurality of lugs are arranged to form a pattern, and wherein the plurality of lugs comprise lug heights ranging from between 0.5 mm and 0.9 mm.
