    at least one pretreatment agent is applied to at least one side of the strip after a cleaning and/or a pickling of the metal surface to be treated, and
    at least one lacquer layer is then applied on at least one part of the pretreated surface, in particular on one side of the strip,
    the coating produced with a pretreatment agent and not with a lacquer is used instead of a priming layer and pretreatment layer, with the side of the strip not intended for subsequent lacquering being preferably coated with a pretreatment agent containing organic resin,
    the side of the strip intended for the subsequent lacquering is coated with at least one pretreatment agent, and
    the at least one lacquer layer is applied as a powder lacquer to the pretreated side of the strip intended for the subsequent lacquering and is stoved.
  2. Method according to claim 1, characterised in that the moisture or residual moisture in the applied pretreatment layer is retained up to the lacquering in order to adjust the necessary electrical conductivity of the pretreated surface for the application of the lacquer layer.
  3. Method according to claim 1 or 2, characterised in that the metal surface before the pretreatment contains aluminium, iron, copper, magnesium, zinc and/or tin and preferably consists of an aluminium alloy, a hot-dip galvanised or electrolytically galvanised iron material, a steel or a full zinc material in the form of strips.
  4. Method according to one of the preceding claims, characterised in that the cleaning and/or the pickling is carried out by spraying and/or brushing with a cleaning and/or pickling solution or immersion in a bath of this solution.
  5. Method according to one of the preceding claims, characterised in that the pretreatment agent is applied by spraying and squeezing with a roller or by immersion and squeezing out with a roller, or in the roll-coat process.
  6. Method according to one of the preceding claims, characterised in that the pretreatment agent is a preparation that contains a polymer dispersion with at least one resin from the group consisting of acrylate, epoxide, phenol, polyester, silicone polyester, polyurethane, styrene and ureaformaldehyde based resin and/or a mixture thereof and/or a mixed polymer.
  7. Method according to one of the preceding claims, characterised in that the pretreatment agent is a preparation that contains at least one resin in the form of a solution and/or dispersion.
  8. Method according to one of the preceding claims, characterised in that the pretreatment agent is a preparation that contains, apart from resin(s), at least one inorganic additive in dissolved form and/or as finely divided powder, for example a carbonate, chromate, oxide, phosphate, silicate or sulfate.
  9. Method according to one of the preceding claims, characterised in that the pretreatment agent is a resin-free preparation that contains aluminium, fluoride, hydrofluoric acid, phosphate, phosphoric acid, trivalent and/or hexavalent chromate, chromic acid, silicate, self-organising molecules, silane, tannin, titanium, zinc and/or zirconium.
  10. Method according to one of the preceding claims, characterised in that, for the application to a strip, a pretreatment agent is selected for one side of the strip that is different to that selected for the other side, with it being possible for the side that is not intended to be subsequently lacquered to be coated with a pretreatment agent containing organic resin.
  11. Method according to claim 5, characterised in that the layer applied with the pretreatment agent is either partially dried or completely dried.
  12. Method according to one of the preceding claims, characterised in that at least one side of the pretreated surface is coated with an organic coating that hardens and/or crosslinks sufficiently in a time of 1 second up to 3 minutes, preferably in a time of 5 seconds up to 2 minutes.
  13. Method according to claim 12, characterised in that for the coating of the pretreated surface a powder lacquer having good mechanical properties, high scratch resistance, good adhesion and high flexibility as regards forming is applied and stoved.
  14. Method according to one of the preceding claims, characterised in that the powder lacquer is applied by spraying, fluidised-bed powder sintering and/or powder cloud technology and stoved.
  15. Method according to one of the preceding claims, characterised in that, after complete drying, the pretreatment layer and/or treatment layer has a layer thickness in the range from 0.1 to 50 µm, preferably in the range from 0.5 to 10 µm, particularly preferably in the range from 1 to 3 µm.
  16. Method according to one of the preceding claims, characterised in that the stoved lacquer layer after the crosslinking has a layer thickness in the range from 5 to 1000 µm, preferably in the range from 10 to 400 µm, particularly preferably in the range from 15 to 60 µm.
  17. Method according to one of the preceding claims, characterised in that a single-layer cover lacquer is applied as sole lacquer at high speed.
  18. Method according to one of the preceding claims, characterised in that a treatment layer that performs the function of a pretreatment and primer is formed with the pretreatment agent.
  19. Method according to one of the preceding claims, characterised in that a powder for a single-colour unstructured coating, a powder for a multicolour unstructured coating, and/or a powder for a multicolour structured coating is used.
  20. Method according to one of the preceding claims, characterised in that the coated surface is protected at least partially by a film or adhesive film.
  21. Method according to one of the preceding claims, characterised in that the coated bodies are optionally shaped or formed, cut - especially in the longitudinal and/or transverse direction - and optionally re-formed, for example beaded, roll-formed, deep-drawn and/or edged.
  22. Use of the products produced by the method according to claims 1 to 21 as internal and external panelling, equipment panelling, e.g. for domestic appliances and small electrical instruments, in particular with decorated external panelling, perforated metal sheets, especially for loudspeakers and sound insulating cladding, space dividers, partitions, furniture units, shelving, internal panelling for vehicles and aircraft, such as for example dashboards/instrument panels, frame and frame constructions, facing materials and lighting installations.
