About us
We are engineers, technicians and designers with in-depth knowledge in the fields of glass, façade, steel and metal construction. Our basic training is in craftsmanship, which allows us to think practically. Thanks to our further training in engineering, business management, welding technology and energy, we are able to optimize our solutions. We are constantly training ourselves and are familiar with the latest standards, laws and developments.
Our principles
- We optimize - according to the motto "less is more", because using less material also means using less energy and therefore better ecology and economy.
- We are practical - our solutions can be implemented. Executing companies appreciate our work!
- We calculate - as engineers we have a gut feeling, but only a calculation can provide clarity!
