From a single source: the Graepel full service for surface treatments

In-house cathodic electrodeposition (CED) and powder coating, hot-dip galvanization and pickling shop

As a full-service partner, we offer our customers a comprehensive range of services, including a wide variety of surface treatment processes.

Of course, you can expect the first-class Graepel quality you are accustomed to when it comes to surface treatment. One more benefit: Your cooperation with us eliminates the need for time-consuming and costly consultation with third parties. Because we handle the development and production of your perforated sheets, gratings and grilles – and we do it just as reliably and competently as we handle the CED and powder coating, hot-dip galvanizing and pickling of those components.

Surface treatment know-how at two locations

At our locations in Löningen and Seehausen, Germany, we have specialized in implementing a variety of surface treatments:

in Löningen we make use of the latest generation of cathodic electrodeposition and powder coating plants. Here, we produce coatings in the first-class Graepel quality our customers are accustomed to. Ongoing innovations allow us to develop our products continuously. Graepel Oberflächentechnik is also an established player in the market as a contracting coating company.
