The primary framing includes transverse steel frames. The steel frames may have clear span dimensions (external dimension of the steel structure) from 8 to 60 m and heights from 3 to 12 m. The roof slope is between 6 % and 40 %. There are no limits on the total length of the building. Centre distance from frame to frame may vary from 4 to 9 m. Construction of buildings with bigger clear span – up to 100 m - is also possible without the supportofintermediate columns and with up to 20 m height.
Annexes, canopies, terraces, roof extensions (eaves), parapets and other architectural and functional additions can be added to the main building.
The elements of the main frames - rafters and columns - are formed by ready hot-rolled profiles or welded H shapes. Depending on the design and technological requirements the implementation by trusses is also possible. Frame joints and all other erection joints are fixed by bolts.

This roof system consists of steel "sandwich" panels, which combine many technical and economical advantages in the construction of thermal and weathertighness coatings. They are easy to install and offer excellent insulation.
