STEICO sites

Feldkirchen near Munich

STEICO’s group headquarters with around 150 employees are located in Feldkirchen near Munich. Our sales department is controlled from these offices. In addition, the application technology, research and development and financial management departments are located in Feldkirchen. At the same time, our headquarters serve as a showroom for the STEICO construction system. Of course, we only used our own materials to build our headquarters. Thanks to its outstanding energy efficiency and the use of photovoltaics, our company headquarters generate more energy than is needed for operation (plus-energy building).
