Steel plate is a flat steel made by pouring molten steel, cooling it, and pressing it.

Steel plate is a flat steel made by pouring molten steel, cooling it, and pressing it. Steel plates can be flat or rectangular, and can be directly rolled or cut from wide steel strips. Steel plates can be divided into thin plates, medium plates, thick plates, and extra thick plates according to their thickness.
