Three former Richard Totzke Neumünster (RTN) fitters founded J.A.G. Metallbau GmbH in 1996. With the increasing success of the company founders Jensen, Aktan and Guenter our staff has now grown to 30 employees today. 

In the modern-standard production halls we achieve a vertical integration of over 70%. In combination with the directly connected office building, this makes it possible for us to react quickly to new situations. From project planning to design to production, we keep everything under one roof. Our assembly teams, consisting of experienced fitters, complete our portfolio as an all-inclusive package.
