Abstract

A composite section features a base of light-weight metallic material as section component and at least one further profiled section component, in particular a profiled strip of another metallic material which is joined metallically as a surface layer to the base section during an extrusion process. Projecting out of the inner-lying face of the profiled strip and directed at the base is at least one projection and/or an additional element which are/is embedded in the base. Each additional element may delimit an undercut space which is filled in an interlocking manner by metallic material of the base.
