Abstract: The method for painting metal plates and. sections includes the steps of pre-treating the section surfaces for preparing the surfaces for painting, distributing a first paint on the section, bringing the section to a first temperature for a time adapted to start a polymerization process of the first paint, cooling the section in order to stop the polymerization process at a selected phase, distributing a second paint at selected locations of at least one surface covered with the first paint which is different from the second paint, bringing the section to a final temperature for a selected time required for the complete polymerization of the first and second paints.
