The invention concerns a method and a device for coating the surface of elongated metal products (1) in particular strips or wires, by applying a metal coating material (2), the product (1) requiring to be coated being continuously passed through a bath (3) containing a molten liquid coating material (2). The invention aims at enhancing the productivity of such a coating device. Therefor, the inventive method consists in: a) measuring the thickness (dIst) of the coating material layer (2) applied on the product (1) after it has passed in the bath (3); b) comparing the measured thickness (dIst) with a predefined value of the layer thickness (dsoll) and in determining the difference (Delta) between the two values: and, c) influencing or modifying at least one parameter (P) of the coating process on the basis of the determined difference (Delta) so as to be closer to the measured value (dIst) of the predefined value (dsoll). |
