About us


The highest level of costumer satisfaction as an integral part of our company’s philosophy.

GIA-TEC (initially GATEC) was founded in 1995 in Cologne:

As a subsidiary of GIA we belong to a group of interdisciplinary operating providers that have one purpose: To trustfully and successfully cooperate with our costumers in the long run.

This intention is intensively lived by each of our employees. We merge high competence, enthusing commitment, flat hierarchies with short decision paths and inspiring teamwork into our own performance capacity.


Thank you for your long-term and harmonious cooperation.

Our clients appreciate our simple and uncomplicated collaboration because they know that they can count on our team in every respect. That is why we are not affected by costumer fluctuation: Our costumers remain loyal to us and appoint us again every time they want to. It is the effect of successful work. We are very proud to be serving our costumers for years, some ever since the establishment of GIA-TEC, and intend to keep it that way.

Likewise essential: GIA-TEC is an owner-managed company and financially completely independent.
