Early and intense for the best results
With the early, intensive examination of every task, we kill several birds with one stone: by the exact analysis of submitted drawings and the detailed coordination, we eliminate sources of error for the further course of the project. The functionality and the precision are thus ensured early on, and thus it saves time and costs. It helps that all steps are monitored and accompanied by the same project manager.
Some examples of assemblies manufactured by C-Technik:
- cutting scaffoldings
- roll change system
- decoiler
- reversing reel
- coiler

Continuity until commissioning
In the case of complete systems, close cooperation and good integration of the individual project steps are indispensable. This is the only way to implement orders according to requirements and also time and cost effectively.
In order to ensure this cooperation and interlocking, we show the status of the project in regular meetings and inform about the preparations for the next project phases. In the spirit of cooperation and continuity, it is also a project manager and a designer to accompany the progress of the project throughout the entire duration, from the initial talks to the commissioning.
Success criteria for our complete systems are the functionality, the accuracy of all components and the precision in the interaction as well as the fast delivery time.
Examples for complete systems:
- slitting lines
- cut-to-length lines
- rolling mills
- packaging lines
- annealing and pickling lines
- galvanizing lines
- hardening lines
- inspection lines
- coating lines
- coil preparation lines
- brushing lines
- laying lines
- wrapping lines
