Coil Coating by DÖR­KEN: A safe, long-term surface protection

The substrate of steel, stainless steel or aluminum that is destined for coating is supplied to the coating plant in coiled form, uncoiled and guided through a looper. In the first stage the coils are cleaned of oil and grease and chemically pre-treated.The actual coating occurs in a roller process, it is precisely tailored to the respective area of use of the coil and can occur in various forms. For example, a base coat (primer) is first applied and annealed, with a topcoat added in a second step.After coating the coil is dried in a special oven and subsequently cooled. If necessary, an additional lamination stage can add a protective plastic film.In the last stage the coated coil is rolled back up again.
