Production, transport and assembly of steel structure for the roof of the production hall with floor plan dimensions of 143 x 239 m, 15-m high, and the rooftop Penthouse with dimensions of 24 x 215 m and the height of 7.25 m above the roof level. The supporting system of the hall is made up of prefabricated reinforced concrete columns and a system of lattice steel roof girders and girders with parts of 24 x 4.2 m in size, which were a challenge in terms of oversized transport to the construction site. The Penthouse support system consists of full-wall steel frames made of rolled HEA400 profiles (columns), or HEA450 (facade).
Part of the work supplied was also the manufacturing and assembly documentation for part of the main load-bearing structure of the roof and the steel structures of the facades in their entirety.
