DHM competencies

Stahl-, Anlagen- und Maschinenbau


After taking over a long-established company for locksmith and staircase construction, Managing Director Dirk Häusgen founded the company DHM in Niederzier, which initially worked for the supra-regional sister company Dirk Häusgen Model House Centers. Dirk Häusgen founded the DHM company for Dirk Häusgen Metallbau in Niederzier, which is why it was also known as “DHM-Niederzier” for many years.
Over the years, in addition to metal construction, steel construction, plant construction and mechanical engineering have also developed more and more.

As an extremely innovative company, DHM trains its employees itself, is committed to promoting the further training of all employees and thus achieves a high level of quality, which is appreciated and gratefully accepted by renowned planning offices and architects. The comprehensive, broad-based expertise in steel and mechanical engineering, as well as the solution-oriented, technical knowledge makes DHM a reliable partner who satisfies its customers efficiently and on schedule.
