In most cases, the back plate of the original factory is not integrally formed with the frame, but also welded. The rear panel is a body panel, which will not depreciate too much after replacement. The rear panel is composed of several pieces, not a whole.
The existing bus tailgate assembly is usually only designed to maximize the space of the trunk and meet the general installation requirements. In practice, due to more and more rear-end accidents in reality, the repair and reassembly rate of rear fender is quite high, so the design of rear fender assembly should consider the protection during low-speed collision and the improvement of vehicle rigidity.
The main function of the rear fender is to absorb the impact force in the event of a traffic accident and reduce the injury to the occupants. This material is made of stainless steel. Use a cutting machine to cut the stainless steel sheet into pieces according to a certain proportion of the vehicle type, then use a punching machine to smooth the corners, and then wrap black rubber on the corners.
If the backboard is damaged, it should be repaired with sheet metal if it can be repaired. Try not to cut it. Once cut, it is an accident car. If it is an accident car, the strength will be greatly reduced after repair, and it will depreciate a lot when it comes back to sell used cars.
In the second-hand car market, car dealers and customers think that the service life, safety performance and handling performance of vehicles with major accidents are not as good as those of the original cars, and will depreciate sharply. If the backboard can be repaired, try not to cut it. Usually, it's better to fix it. If cutting can't be avoided, you must find a professional maintenance agency for maintenance.
So simply replacing the rear fender will not involve the safety performance of the vehicle. As long as the vehicle does not hurt the rear longitudinal beam, it will not be regarded as an accident vehicle, and the owner need not worry too much.
