Stahl- und Metallbau IHNEN

“Steel construction is our job, quality is our passion.”


The company Stahlbau IHNEN was founded in 1967 when Wilhelm Ihnen took over the company Beu and its five employees. The focus was set on locksmith works for contractors and architects in Aurich and the surrounding area.

After two years the company moved to the Mühlenwallstraße. The first major client was Volkswagen for whom Stahlbau IHNEN manufactured 3,000 benches for the restrooms and breakfast rooms.

The first central location was established in the Finkenburgweg. The number of employees rose to about 100. At that time Stahlbau Ihnen was also manufacturing platforms, working platforms and materials-handling systems for Volkswagen. In addition Stahlbau IHNEN received among others orders from Hochtief Hannover, Mannesmann Demag Offenbach, Opel Rüsselsheim, Mercedes Benz Bremen or Eisenmann Böblingen.

The company steadily grew with its orders, invested in further plants and due to its performance, services, delivery on time and the excellent cost-performance ratio Stahlbau IHNEN made a name for itself, nationally and internationally.

In 1996 Thomas Ihnen joined the company’s management and in 2000 his brother Willm Ihnen followed. With the same consistency they invested in new technologies and extended e.g. the serial production. Step by step the plant was extended. In 2009, a further hall and an office building with the departments planning and construction were inaugurated. The latest highlight is the 5,000m2 complex for the sheet metal processing, a high bay warehouse and connected machinery to manufacture sophisticated sheet metal components individually or in series production, fully automated and with highest precision.
