Wilfred Windhagen

Partner 1980 - 2018

For over 40 years, corrosion protection has been the core business of Steger and Windhagen, and is still the main business and support of the entire company to this day.

In 1954, the company’s founder, Wilhelm Steger, was operations manager with the Dumont company, which he continued to lead as owner and managing director in 1976. Dumont KG’s business portfolio comprised industrial and ship cleaning.

At the end of 1999, Steger & Windhagen GmbH added winch construction to their portfolio. The long-term management succession within the family business was also firmly established at this juncture. Andreas Windhagen, a qualified measurement and control technician, and Dirk Wallner, a metal construction graduate and welding expert, joined the company and now manage the business. Since the start of 2007, Hans-Dieter Bergenthun, another metal construction graduate and welding expert, has also been part of the management team, as operations manager.

The commercial success of the new winch construction area was also demonstrated by the building of a new production hall, which was inaugurated at the end of 2009. A spacious, three-ship production hall was erected, which accommodates spray booths equipped in accordance with the latest environmental standards, the entire administration department and the staff canteen and changing rooms, along with assembly and storage areas, all under one roof.
