Although our website has been designed with the "self-help" concept and can answer many of your questions, complex topics may call for a personal consultation from a neutral, third-party copper expert.   

Our qualified experts are at your disposal and are, in most cases, free of charge.  Due to the heavy demand of our experts, you may experience a short waiting period.  To facilitate the quickest possible reply, please note the two points below: 

  1. Call our main number +49 (0)211 239 469 0 between the hours of 8:00 and 18:00, and your request will be passed on to the responsible DKI- expert.  You will then be contacted by a DKI-expert using the contact information you provided.
  2. Alternatively, you can contact us by completing the online form below.
