The company Spetsgradstroy offers the following solutions in the supply of complete buildings
The frame of the building:
the main load-bearing frames of welded I-beam columns and crossbars of variable cross-section are made of high-strength steel C345 (09G2S). All welded structures undergo shot blasting (degree of purification S.A. 2.5), are covered with a primer 80 microns thick. Fastening of columns of the main bearing metal frame to the foundations is carried out by anchor bolts, which are made of steel C345 (09G2S) and are supplied in accordance with the plan of anchor bolts. Wind connections are also made of steel C345 (09G2S).
Additional load-bearing frame (roof girder system):
galvanized steel cold-bent Z-, C-shaped profiles (Zn 275 g/ sq.m). Are made of steel grade STE 350 3Z (minimum yield strength 389 N/ sq.mm). When installing Z-shaped girders, their connection provides a continuous circuit of the girder system as a whole (see Fig.).
Fasteners:
The fastening of the elements of the main supporting frame between themselves is carried out with galvanized bolts of class 10.9 according to the requirements of EN ISO 898-1 and EN 14399, Parts 1, 2, 4, and 6, the most commonly used bolt diameters are 20, 22, 24 mm. Fastening of the elements of the additional frame is carried out with bolts of class 4.6. All necessary fasteners, including anchor bolts, are included in the delivery package.

- The use of high-strength steels (minimum yield strength of 345 N/sq. mm) can significantly reduce the metal consumption of structures and, accordingly, reduce the cost of foundations and installation of the building.
- The variable height of the cross-section of the structures ensures the most efficient use of the internal volume of the building and reduces operating costs.
- Steel 09G2S is the most resistant to cracks in the weld.
- The use of Z-shaped profiles reduces transportation costs due to economical packaging.
- Zinc coating of wall and roof girders provides corrosion protection, increases the service life of structures and has an aesthetic appearance.
