Plain carbon structural steel, also known as ordinary carbon steel, has a wide range of carbon content, properties and restrictions on the content of phosphorus, sulphur and other residual elements. According to the delivery guarantee conditions are further divided into three categories: Class A steel (Class A steel) is the guarantee of mechanical properties of steel. Class B steel (Class B steel) is the guaranteed chemical composition of the steel. Special category steel (C steel) is a steel that guarantees both mechanical properties and chemical composition, and is often used in the manufacture of more important structural components.

According to the carbon content of the composition is divided into: low carbon steel, medium carbon steel and high carbon steel; according to the use is divided into: carbon structural steel and carbon tool steel. Round steel is a long, solid steel bar with a circular cross-section, which is common in construction and hardware accessories such as round steel bars for concrete and solid seamless steel pipes. Round steel is classified according to the process: hot rolled round steel, forged round steel and cold drawn round steel.

Some carbon structural steels also add trace amounts of aluminium or niobium (or other carbide-forming elements) to form nitride or carbide particles to limit grain growth and make the steel stronger, saving steel. To adapt to the special requirements of professional steel, the chemical composition and properties of ordinary carbon structural steel to adjust, thus developing a series of ordinary carbon structural steel professional steel (such as bridges, construction, reinforcing steel, pressure vessel steel, etc.).
