Michael Gross and Gunter Mohr
Owners and Managing Directors

The company owners, Michael Gross and Gunter Mohr, communicate openly, honestly and as partners with their clients and the approximately 120 current employees. As a reliable partner and proud medium-sized company, we’re a training company and successful innovator. Our teams work reliably, competently and safely.

Visions and values

We are contributing to the city of the future because we bear responsibility for sustainable development and invest in climate protection measures. For example, we are working with the University of Kaiserslautern to manufacture facades from recycled aluminium and support research in this area.

Resource-conserving, eco-aware behaviour to reduce CO2 emissions and the innovative use of technology not only reduce waste and prevent pollution, but also create economic benefits for our customers by saving energy and materials.

We implement architecturally sophisticated ideas with our facade constructions throughout Germany. In addition to standards, we offer special solutions for unusual requirements.

As a reliable partner, our name stands for timely and high-quality workmanship. Only quality materials are processed at our manufacturing facilities for making our products, which are then delivered to the construction site ready for installation and on schedule.

Our clients’ satisfaction is our top priority.


We are firmly convinced that our sponsoring activities in the areas of sports, education, and social affairs are an excellent investment in society and in the quality of life of both current and future generations. This is why we support regional and supra-regional projects, which we select carefully.

Our donations in cash, in kind, and in services benefit the following projects and institutions: S.V. Medard 01, Ethno Jazz Festival Burg Lichtenberg, the municipality of Medard, Bethanien Children’s and Youth Village Eltville-Erbach, Strahlemann Foundation and Indienhilfe Saar (aid for India).

Each of these projects and institutions has been chosen based on our careful consideration, and we are proud to support them through our contributions. We believe that these donations not only benefit the organizations themselves but also have a positive impact on the communities in which they operate. By investing in these projects and institutions, we hope to contribute to a better future for all.
