A method for producing components, in particular for energy systems such as fuel cells or electrolyzers, has the following steps: rolling-off a metal sheet having a thickness of less than 500 m, from a first roll; transporting the metal sheet through at least one coating plant in which the metal sheet is coated on at least one side by means of a physical and/or chemical vapor deposition process; performance of at least one forming process on the coated metal sheet; formation of a plurality of components by parting from the coated metal sheet; and rolling-up of the remaining coated metal sheet to give a second roll, with continuous transport of the metal sheet from the first roll to the second roll being carried out.
