Materials: columns are made of concrete of strength class C 12/15 - C 25/30. Main working reinforcement: steel rods of periodic profile, class S 500.

Field of application: Columns are designed for single-storey buildings with bridge cranes, with a height from the level of the clean floor to the bottom of the rafters of the coating structure of 8.4  m.

The pitch of the extreme columns is 12 m in accordance with the unified overall diagrams.

Materials: columns are made of concrete of strength class C 12/15 - C 25/30. Main working reinforcement: steel rods of periodic profile, class S 500.

Application: Columns are used in end walls of longitudinal walls of single-storey industrial buildings with self-supporting and load-bearing panels 6 m long.

Inner face of panel walls is located with clearance of 30 mm relative to outer face of columns.

Materials: columns are made of concrete of strength class C 12/15 - C 25/30. Main working reinforcement made of hot-rolled steel of periodic profile, class S 500.

Application: Slabs with a nominal length of 12 meters (width 3 m) are designed for use as flooring in the coatings of industrial buildings with a pitch of building structures of 12 m and a roll roof. Slabs shall be laid on reinforced concrete rafters. In addition to ordinary ones, plates with round holes are made for the arrangement of spillway funnels. Plates measuring 3x12 m are designed for uniformly distributed load p = 135775 daN/m2.

Materials: Slabs are made of concrete of strength class C 25/30 and C 30/37 on fine gravel (crushed stone). The main stressed reinforcement is made of hot-rolled steel of a periodic profile of various classes, from cold-drawn high-strength wire of a periodic profile of class BpII or from seven-wire strands of class P-7.

Application : Panels made of cellular concrete are solid single-layer. Designed for the construction of walls of single-storey heated frame buildings with a wall column pitch of 6 m.

Materials: For cellular concrete panels, autoclave cellular concrete of strength class B 3.5 and B 5 is used. Reinforcement is made of hot rolled steel of periodic profile of classes S400, S500.

Rigidity in the longitudinal direction is provided in buildings with suspended equipment, provided by the installation of stiffness links (steel) located in each row and temperature compartment. Cross ties are arranged in the axes EHF/12, E-G/14 and they have the designation BC1 and BC4, and portal ones between the axes 79, B-D, and denote BC2 and BC3. 

The glazing of an industrial building is usually tape with one row of glazing. Double glazing is used in the heated building. Wooden blocks for filling window openings consist of boxes, bindings with glazing and a windowboard.

The gate is designed for rail-free transport. Their value should exceed the dimensions of transport in a loaded state by at least: in width by 600 mm and in height by 200 mm.

An open gate consisting of frames and canvases was designed. The size of the gate is 3600x4000 mm.

Outside the building in front of the gate, ramps with a slope of 1:10 are arranged for the entry and exit of rail-free vehicles.

Beams are installed on reinforced concrete columns at a pitch of 12 m in spans of 24 and 18 m.

Beams are designed for load from two adjacent electric bridge cranes with lifting capacity Q = 50t. and Q = 5 t. light and medium operating modes.

The cross section of the beams is T-shaped with a shelf in the compressed zone.

Materials: Beams are made with preliminary stress from concrete grades C 18/22.5 - C 30/37. The main, stressed, reinforcement is made of steel of classes S500, BpII, or II7.

The roof is pitched. The material for the roll roof arrangement is Isoplast (lower EPP layer - 4.0; top layer of RPP - 5.0), laid on the brace. Additional layers of water-insulating carpet are laid in places of adjoining roll roofs to protruding elements and in places of arrangement of temperature joints in coating. Carpet is brought on protruding elements and attached to them by dowels.

Internal organized drainage is designed in the building, as it is heated. The location of the water intake funnels is assigned in accordance with the dimensions of the coating area and the transverse profile. Waterproofing in the places of installation of water intake funnels is achieved by strengthening the main waterproofing carpet with three mastic layers with glass cloth reinforcement.

Concrete floors on the ground arranged for concrete preparation are designed in the building.

The construction of concrete floors does not require much labor. Monolithic concrete floors are made single-layer 2550 mm thick. Before concrete laying, preparation surface is cleaned, wetted with water and ground with cement milk. Concrete is laid in strips 2.53 m wide, bounded by lighthouse racks. Concrete mixture is leveled by rule and compacted with vibration racks.

The surface of concrete coatings, after the set of concrete of sufficient strength, is ground and smoothed with ironing (rubbing into the surface of the coating of dry sieved cement)

Concrete floors are arranged in rooms with high humidity, as well as, where it is possible to get minimal oils, acids and alkalis onto the floor.

Floor is arranged for concrete preparation with thickness of 100 mm. Class C12/15C25/30 concrete. Coating thickness 50 mm.
