Complete mechanical manufacturing of plant and fixture systems

Custom assemblies made of steel, aluminum or mixed materials – fully assembled, painted and ready to install

We are your specialist for plant and fixture systems

Fully covered: machining, welding, surface finishing, assembly & delivery
Parts up to 20 m in length and 10 tons in weight.
Typical situations buyers face before starting a collaboration

Are your requirements really being met satisfactorily by your current suppliers?

Do you occasionally encounter challenges with size and weight?

Are there insufficient machines for large and heavy components, resulting in improvisation? With risks for accuracy and quality?

Is there a lack of experience with fixtures in some cases?


The industry-specific requirements of large systems are unknown?

Are the responsibilities of the project organization often unclear?

Do you actually have to take care of the entire request? Are you lacking a permanent and reliable contact person, which costs you time and nerves?

Are the certificates not sufficient?


There is a lack of approvals in accordance with DIN EN 1090 or ISO 3834 – and therefore a lack of delivery capability?
