ABSTRACT:
A method of covering steel parts onto the outer surface of which there is applied a plastic coating which is surrounded by an embedding material. In order to obtain in a simple manner increased adherence between plastic coating and embedding material a granular powder or granulate is applied to the plastic coating which is still not completely hardened so that the individual powder granules are received only in part by the coating surface, so as to form profiling projections. In accordance with a variant, the profiling projections can also be formed by the side flanks of a helical rib which is extruded onto the heated plastic coating.
