The present invention concerns a method for production of a supporting member with an at least partially closed cross-section, having at least a first metal shell and a second metal shell which are connected together at least in portions in the longitudinal direction. The method includes a provision of at least a first and a second metal blank. At least a first and a second metal shell are produced from the respective first and second metal blanks. The first and second metal shells each have at least one floor with two protruding uprights spaced apart from each other and integrally connected to the floor. The first and second metal shells are positioned such that the uprights of the metal shells come into overlapping contact.

The disclosure relates to a blank-shaped or strip-shaped semi-finished product comprising at least one first metal layer and at least one plastics layer, which are joined over their full area to one another to form a metal/plastic composite. The material thickness of the metal layer is not more than 1.5 mm. The material thickness of the plastics layer is at least 0.2 mm. A method for producing said product is also provided. One object of the present invention, of providing a semi-finished product which is significantly lighter than the semi-finished products used in the prior art, is achieved for a semi-finished product.
