ABSTRACT:
The present invention reduces the expense of treating the surfaces of a plate material. This surface treatment method treats the surfaces of a plate material that is rolled with rolling oil and employed as a cooling fin of a heat exchanger, and includes a preparation step and a coating application step. In the preparation step, the plate material is prepared. In the coating application step, a coating is applied to the surface of the plate material without carrying out a degreasing treatment.
