About products
Carbon structural steel: a kind of carbon steel. The carbon content is about 0.05%~0.70%, and some can be as high as 0.90%. It can be divided into ordinary carbon structural steel and high-quality carbon structural steel. It is widely used in railway, bridge, various construction projects, manufacturing various metal components that bear static load, unimportant mechanical parts and general weldments that do not need heat treatment.
