Steel plate is a material often used to create metal products. Manufactured to different thicknesses and widths, steel plate is cut and welded together to create a final product. There are different types of plate, such as stainless and high-carbon steel plate. Some types of plate steel are used in the construction of buildings while others are used in the creation of everyday items, such as wood furnaces, and not so everyday items, such as ship hulls. Steel plate is often referred to as flat steel.

As high-temperature steel is rolled into sheets, the steel gains strength. Layer upon layer of steel is compressed and forged into a single piece of steel until the proper, final dimensions are achieved. As the flat steel sheet cools, it hardens into a usable piece of steel. The type of steel that is created is dependent upon which ingredients are used to create the molten steel.
