- Bumper cross member for floor and roof, front and rear
- the raw ka rosse with a safety cage usually consists of a hardened steel sheet with about 1, 500 MPa strength. In many cases Al-Si-coated steel sheets are used. For the production of a component from hardened steel sheet the process of the so-called press hardening was developed. This steel sheets are first on

- Impact can therefore not be sufficiently converted into deformation heat.
- components with high strength are basically desirable in order to obtain components of high mechanical strength with low weight.
- high-strength components should be able to have partially soft regions, thus achieving the desired, partially increased deformability in the event of a crash. This is the only way to reduce the kinetic energy of an impact and minimize the acceleration forces on the occupants and the rest of the vehicle.
- modern joining methods require de-consolidated points, which allow the joining of identical or different materials. Often, for example, crimping or riveting joints have to be used, which presuppose deformable areas in the component.
- Soft edge regions of the component also allow a contour cut already in the tool and can thus lapse the laborious laser cutting.
