Developed projects

In view of the current development on the construction market, a significant increase in production volume can not be expected. We want to use this period to increase the qualification of not only managers but also assemblers. At the same time, we want to emphasize the training of workers on more modern roof and facade systems. We will place great emphasis on the design and craftsmanship of the details so that the resulting quality of the work is over-standard. We want our company to be ready to offer new high-quality products to its customers after a temporary slowdown in production.
