Modules

A large part of our projects involves manufacturing specialised individual module frames as well as large series of steel module frames. The module frames are delivered to the client, who then equips them for use as, for example, surgical rooms. At the final destination, several modules can form the framework for different types of facilities, such as hospitals and other buildings for the pharmaceutical, mining, and manufacturing industries.
