The core markets for KHK are France, Germany, and the Benelux countries. Approximately 80% of the total turnover is currently being generated here. Other European markets such as Poland, the Czech Republic, Spain, etc. will be witnessing intensified efforts in future.

Raw materials

PVC is the basic material. The PVC off cuts and lumps are procured by way of acceptance agreements with major window and/or profile manufacturers.


A strategic orientation towards opening up the markets of the new EU member states is a medium term component of the objectives.

Customer- oriented work and action

KHK is a stable enterprise with grown know-how. Every project and every assignment is handled responsibly and reliably, always putting the interests of the customer first.
