Automotive sheet metal is a technical means of automobile repair, which means that the car body should be repaired after collision, that is, all the work except anti-corrosion and decorative painting of the car body. In short, automotive sheet metal is to completely repair the faulty and damaged car body.

Automotive sheet metal is also called cold working. To put it bluntly, if the appearance of the car body is damaged and deformed, the sheet metal process is needed. Automobile collision repair has developed from the initial "welding repair" to the secondary manufacturing and assembly of the car body. The repair of vehicles in collision accidents is no longer a simple automotive sheet metal knock, and the quality of repair can not be observed only by naked eyes.
