The main function of a bumper is to protect the car's body in a slight collision, typically at parking speed. The bumper structure on modern automobiles generally consists of a plastic cover over a reinforcement bar made of steel, aluminum, fiberglass composite, or plastic. In most jurisdictions, bumpers are legally required on all vehicles.
The first element is an impact absorbing spring device, usually gas-filled cartridges which mount the front bumper to the chassis. This allows the bumper system to absorb minor impacts without any damage. The next part is the steel or aluminum support structure, which is a lateral beam. On top of that is a honeycomb or egg-crate shaped plastic piece made of HDPE which defines the bumper's ultimate external shape and supports the shape of the bumper cover. On the rear, these can be attached to the car's other bodywork or components.
