According to the minimum yield point, the strength level of structural steel for hull is divided into: general strength structural steel and high strength structural steel. Ship plate refers to hot-rolled steel plate used to manufacture hull structure produced according to the construction specifications of the classification society.

Carbon steel plate is a type of material that is used in large quantities. It is divided into ordinary low carbon steel plate and special steel plate, including low alloy high strength steel and corrosion resistant and heat resistant composite steel plate. Ordinary low carbon steel plate is divided into cold rolling and hot rolling. Cold rolled steel plate has good surface quality and precise thickness and size, and is mostly used to manufacture car bodies. Hot rolled plates are mostly used to manufacture frames.
