ABC column is not only a metal column supporting the cockpit roof, but also plays an important role in protecting the cockpit members. When the vehicle is tilted or overturned, ABC column can effectively prevent the cockpit from being squeezed and deformed. Therefore, the strength of ABC column is of great significance to the life in the car. The ABC column of some high-end cars is integrated with the body including the frame, and the safety is greatly improved.
