Is it necessary to repair the car's side sill?
1 Answers
The car's side sill should be repaired when severely dented. Here are specific details about the car frame: 1. Function: The car frame is typically made of high-strength steel plates, primarily connected by riveting crossbeams and longitudinal beams to form a rigid structure with sufficient strength and stiffness to bear the vehicle's load and impacts from the wheels. 2. Deformation: If there is severe deformation or wrinkling, replacement is necessary. Since the frame's longitudinal and crossbeams are mostly welded together, deformation requires cutting and welding new components onto the deformed frame.
