The invention concerns a method for chemical treatment of metal strips which consists in applying unilaterally or bilaterally a treating liquid on the surface of metal strips using a roller coater, and in drying said liquid without intermediate rinsing. Said method is characterised in that it consists in using a lap roll as roller coater. The treating liquid is preferably a phosphating solution, a chromating solution, an acid or alkaline passivating solution, a treating solution based on complex fluorides or a solution or dispersion of an organic film-forming agent. |
