The damage of the front part of the automobile sheet metal parts is caused by the head of the vehicle hitting another vehicle or other objects. The impact force depends on the vehicle weight, vehicle speed, impact object and impact area. If the collision is small, the bumper will move backward, causing bending and deformation of the front side member, bumper seat, front fender, radiator support and engine hood lock pillar.

If the collision is further increased, the front fender will be hit on the front door, and the hood dumpling chain will bend up and touch the hood, and the front side beam will wrinkle and contact with the beam where the suspension is located. If the collision increases further, the front fender apron and the front body pillar (especially the upper area of the front door dumpling chain) will be bent and deformed, and the front door may be knocked off. In addition, the crease of the front side member is increased, causing the suspension beam to bend, and the partition and floor between the engine and the cab will also bend to absorb the collision.

Lateral damage will cause deformation of the door, front side panel, middle pillar of the vehicle body and even the floor. When the front fender or rear quarter panel is subjected to a large vertical impact, the impact force will be transmitted to the vehicle body on the other side of the impact point.

If the front fender is impacted in the middle, the front wheel will retract. The impact force will be transmitted to the longitudinal beams on both sides through the beam where the front suspension is located. If the impact force is large, the suspension components will be damaged and the front wheel alignment will be changed. Side impact can also cause damage to the steering gear and its support.

The top damage is caused by falling objects hitting the vehicle or vehicle rolling. The top damage is not only limited to the roof panel, but also may cause damage to the roof side member, rear quarter panel and window.

When the vehicle rolls over, the body pillar and roof panel will bend and the corresponding pillar will be damaged. Depending on the rolling mode, it may also cause damage to the front or rear of the vehicle body. The distinguishing feature is that the door and window are deformed and easy to find.
