The extremely high standard that we set on the perfection of our products also applies to their surfaces. Therefore the Graepel workflow also includes different processes of surface treatment. Because this is the only way for us to take the paramount issue of quality into our own hands.
At the Löningen site, Graepel runs an in-house powder-coating plant which is designed for series production. It generates painted, durable surfaces which have proven consistently high quality in the salt spray test. Powder coating is also provided to series production customers, irrespective of our Graepel products.
At Seehausen, Graepel has a company hot-dip galvanizing plant, providing longstanding know-how in the field of corrosion protection, as well as an aluminium and stainless steel pickling shop. These services can also be utilized by corporate and private customers starting from a quantity of one piece. We look forward to receiving your requests.

Graepel Oberflächentechnik GmbH & Co. KG was founded with the objective of specifically adapting surface coating to the Graepel product range with regard to the issues of quality and coating technology. Due to their specially punched geometry, perforated sheets place very high demands on the coat. Punching burrs must be reliably and permanently covered and the small holes that can for instance be found in ventilation plates, must not be minimized during the coating process. It would further reduce the complexly designed cross sections and impede the light air flow.
