  • Peat fuses are very easy to produce by an adapted cross section of the profile.
  • disadvantages are also associated with the integral construction, in particular the required strength of a car body is not constant over the entire length of the car body. Areas for the introduction of large forces, e.g. the coupling connection or the main crossbeam require other profiles than less loaded sections of the undercarriage. Areas surrounding large openings such as double-winged passenger compartment doors are to be made with greater strength than wall areas between these large openings.
  • Integral construction can not be adapted to it, so nevertheless, the same profiles are used in places with little load as in places with high loads. This leads to a higher vehicle weight, a reduced payload and higher energy consumption. There are not any
