Steel by use:
Steel can be divided into structural steel, tool steel, special steel and professional steel according to different uses.
Structural steel is further divided into structural steel for construction and engineering and structural steel for machinery manufacturing. Structural steel for construction and engineering is steel used to manufacture metal structural parts in buildings, bridges, boilers, or other projects, mostly low carbon steel. Since most of them have to be welded, their carbon content should not be too high. Mechanical manufacturing structural steel is used to manufacture structural parts on mechanical equipment, which are basically high-quality steel and high-grade high-quality steel.
