A type of material that uses a large amount of steel plates is divided into ordinary low-carbon steel plates and special steel plates, including low-alloy high-strength steels and corrosion-resistant and heat-resistant multi-layer steel plates. Ordinary low-carbon steel plates are divided into two types: cold-rolled and hot-rolled. Cold-rolled steel plates have good surface quality and accurate thickness dimensions. They are mostly used to make car bodies. Hot-rolled plates are mostly used to make car frames and the like.
