A hollow section, comprising:
- a frame section made of plastic and defining a longitudinal axis, said frame section having an interior subdivided in several inner chambers by a plurality of partition walls extending in a direction of the longitudinal axis;
- and
- a plurality of stiffening elements made of metal and received in the interior separate from one another and without interconnection of the stiffening elements to one another, for forming some of the partition walls and for realizing a reinforcement of the frame section, wherein each of the stiffening elements has a rectangular cross section and is secured directly to the frame section, wherein each of the stiffening elements includes punchings which are so configured that application of any section in a direction transversely to the longitudinal axis of the frame section results in an area which covers a same amount of metal.
