Steel plates are flat pieces of steel that come in various thicknesses and sizes. They are made from molten steel that is poured into molds and then cooled. These plates are commonly used in construction, manufacturing, and various industrial applications due to their strength and durability. The versatility of steel plates allows them to be used in creating structures like bridges and buildings, as well as in machinery and vehicles. They can be cut, welded, and shaped to fit specific needs, making them essential in industries such as automotive and shipbuilding.
