Product Description

  Factory Direct Hot-Rolled EN10025 S355JR SS490M Auto Hinge Steel 



 

The car door hinge, also called a hinge, is typically manufactured via stamping or hot rolling processes. Its main role is to connect the vehicle door to the body, maintaining the door's positional relationship while enabling smooth opening and closing. Comprising at least two interconnected components - a body-mounted part and a door-mounted part - its structural design includes key elements such as page boards and rotary arms.
