PURPOSE: Provided is a process for producing a metal article, the surface of which has been pretreated with a silane composition and then extrusion-coated with a polyamide molding composition. CONSTITUTION: An extrusion-coated metal profile prepared by a process comprises applying a mixture which comprises an organosilane composition which is prepared from Q mols(a) of alkoxysilanes which have a functional group and have the formula: A-Si(R1)y(OR*)3-y, and M mols(b) of alkoxysilanes selected from the group consisting of trialkoxysilanes(alpha) of the formula: R2-Si(OR**)3 and/or from the group consisting of dialkoxysilanes(beta) of the formula: R3R4Si(OR***)2 and/or from the group consisting of alkoxy compounds(gamma) of the formula: Me(OR***)n, wherein A is a substituent which has, bonded directly or via an aliphatic or aromatic hydrocarbon radical to silicon, thereto at least one amino, alkylamino, dialkylamino, amido, epoxy, acryloxy, methacryloxy, cyano, isocyanato, ureido, thiocyanato, mercapto, sulfane or halo group, R1 is methyl, ethyl or A which is defined above, y is 0 or 1, R*, R**, R*** and R***, independently of one another, are an alkyl group having from 1 to 8 carbon atoms or a corresponding alkyl group which is substituted by an alkyl£(poly)ethylene glycol| radical, R2, R3 and R4, independently of one another, are an alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl or aromatic group, in each case having not more than 18 carbon atoms, or a group of this type which is partially fluorinated or perfluorinated and/or is substituted by alkyloxy and/or by aryloxy groups.
