Our history

FOS is a family-run business in its fifth generation

The company Wilhelm Lüling was founded in Altena-Dahle by Friedrich Ossenberg-Schule. The small town surrounding the medieval Altena Castle was shaped by the metal and wire industry as early as the 14th century. The beginnings of the metal processing company were quite modest. Shoemaker tools and metal household goods were manufactured. The founder Friedrich Ossenberg-Schule was a blacksmith and his family worked hard to make a living. The industrial depression was particularly depriving. During the Second World War, production continued to be very limited.

After the war, the company specialized into producing roof, ridge and facade clips. Due to innovative product design, various patents were filed. Modern concrete construction and new technical regulations in Germany brought a particular boost in 2011. In the recent decades company headquarters and the production plants have been constantly expanding, the workforce has grown to currently 90 employees.

Due to the commitment of management and staff, a small start-up developed into a well-positioned, internationally active company. The company's history is shaped by the people who have worked and are currently working at FOS.

Friedrich Ossenberg-Schule GmbH + Co KG is a family-run business in its fifth generation. The modesty of the former shareholders and their Christian involvement are seen as model behaviour. The current generation also lives and acts according to these values.
