Facade systems consisting of steel beams with slots, as an example of structures for prefabricated construction

Facade systems consisting of steel beams with slots. The use of lightweight building systems originates in the United States of America and Northern Europe. In these countries, it was required to ensure fast pace of construction due to the long cold period. Due to their minimal negative impact on the environment (using the example of quick prefabricated construction), lightweight metal structures are progressing very rapidly nowadays all over the world.
