Technical support

Your project is of key importance to us. We do not expect you to subordinate to our capabilities. On the contrary, we will create a solution which fulfils your expectations.

We are constantly refining our services in order to regularly raise their standard. Working out individual reports, connecting information systems and sophisticated support in design and development of unique products (designs, recommended materials, cost saving, assistance in selection of suitable technology) – these are only a few examples of our customer-oriented activities. Of course, we welcome communication in English, German, French and Czech. In many countries our business representatives are at the disposal of customers.

The production potential of GZ would not be enough in itself to ensure customer satisfaction. It is our aim to make cooperation with GZ a pleasant experience.

We will be very grateful for any comments and suggestions you wish to make, which can be sent to
