A method for producing a structural component for a vehicle body, the method includes forming a flat carrier material made of a metal, a thermoplastic material and/or a fiber-reinforced thermoplastic material to give a three-dimensional component, and providing a supporting material made of a thermoplastic material, such that the carrier material and the supporting material form an integral material composite. The material composite made up of the carrier material and the supporting material is produced before the carrier material is formed. The material composite is heated before the forming in order to make forming of the thermoplastic material possible. A rib structure is impressed into the supporting material during the forming of the material composite, and the temperature of the three-dimensional component having the rib structure is controlled, it preferably being cooled.
