OptimuS

The building is based on the frame with tapered beams.

  • Welded tapered I-beams
    • Variable depth of a structure element ensures the most efficient use of strength characteristics of sections without losing the economic efficiency of the whole structure in general.
    • These buildings differ from standard buildings with roof t/eng/ses in a low construction height, easy transportation and installation, and exquisite appearance. Low construction height allows for more optimal use of the interior space of the building.

    Economic efficiency of the frame based on tapered beams is ensured by:

    • the optimum choice of properties of bearing elements sections;
    • the use of high strength steels; application of light-gage galvanized steel structures for girts and purlins of the building;
    • the use, by agreement with the customer, of a horizontal layout of wall panels, which eliminates the number of additional wall girts.
  • Frame
    • Columns, tapered beams, roof purlins, column-to-roof bracing system, end beams and studs are bearing elements of the structure.
    • Frames are spaced at 6 m.  End frames consist of beams and studs, studs being spaced at 6m. 
    • Columns of regular frames are tightly connected with foundations for buildings with spans of 18 and 24 m and articulated for buildings with spans of 30 and 36 m.
    • The longitudinal frame stability is ensured by the vertical braces between columns and roof bracing.
    • Beams, columns and bracing system are supplied preprimed, girts and purlins are supplied galvanized.
    • Girt support columns are hinged to the foundations.
    • Columns and frame struts are hinged to the foundations, columns and regular frame girders are flanged with the help of high-strength pretension bolts for 30 and 36 m spans and are hinged for 18 and 24 m spans, frame struts are hinged to end beams with precision bolts, girders junctions are hinged with the help of high-strength pretension bolts
  • Types of Cladding Structures
    • Buildings can be insulated or non-insulated.
    • Wall and roof cladding for insulated buildings can be made of sandwich-panels or with sheet-by-sheet assembly. For non-insulated buildings profiled sheets are used.
    • Cladding structures

      Advantages

      Premium

       

      Roof: sandwich-panels (150 mm)

      Walls: sandwich-panels (120 mm)

      Sandwich-panels with a mineral wool or polymeric core are the most efficient and practical option for a cladding structure.

      o    Installation of wall and roof panels takes much less time which automatically makes the installation work cheaper.

      o    Moreover, such works don't require heavy and costly material handling equipment.

      o    There are practically no maintenance costs: buildings with sandwich-panels as cladding structures can do without repair for a long time.

      o    Sandwich-panels show good thermal insulation and fire-resistant properties, resistance to hostile environment, and conform with all sanitary standards.

      Business Plus (combined version)

       

      Roof: sheet-by-sheet assembly (heat insulation 150 mm, with profiled sheets as internal skin)

      Walls: sandwich-panels (120 mm)

       

      Sheet-by-sheet assembly (3-layer): internal and external skins consist of a profiled sheet and a layer of mineral wool insulation between them.

      Sandwich-panels with a mineral wool or polymeric core are the most efficient and practical option for a wall cladding structure.

      o    In some cases it is recommended to use a combination of cladding structures to get all useful features and properties of the applied materials. For example, a sheet-by-sheet assembly of the roof and use of sandwich panels as a wall cladding can save on the cheaper materials without sacrificing basic technical characteristics.

      Business

       

      Roof: sheet-by-sheet assembly (heat insulation 150 mm, with profiled sheets as internal skin)

      Wall: sheet-by-sheet assembly (heat insulation 100 mm, not covered with profiled sheets from inside)

       

      Sheet-by-sheet assembly (3-layer): internal and external skins consist of a profiled sheet and a layer of mineral wool insulation between them.

      Sheet-by-sheet assembly (2-layer) on the walls: rolled insulation with reinforced foil surface fixed with a profiled sheet from the outside of the building.

      o    Installation is performed in stages.

      o    Considered as one of the most inexpensive ways to insulate steel-framed buildings.

      Cold

       

      Roof: profiled sheets

      Wall corrugated sheets

      A profiled sheet is a light-gage hot-dip galvanized steel that can be additionally coated with polymer or paintwork. Roof profiled sheets have a deeper profiling which increases the bearing capacity of the sheets. Wall profiles have a smaller rib height.

      o    Mainly used for "cold" warehouses of temporary storage, sheds and annexes, some types of agricultural buildings.

OptimuS Advantages

OptimuS standard hall is characterized by a higher durability due to the use of С345 (09Г2С) high-strength steel that has unique consumer-oriented properties: high strength, excellent formability, good weldability. Thanks to the application of steel C345 for beams production, it became possible to reduce the weight of the frame structure without sacrificing the strength characteristics of the building. 

  • Compactness and light weight of the frame

    Application of elements based on welded tapered I-beams allows creating structural design with the most optimal weight.  Low construction height compared to truss structures allows for significant reduction of the gross building volume. The total content of steel varies between 27 kg/m2 and 39 kg/m2 depending on the height and span width of the structure.

  • Corrosion and fire resistance

    Obvious advantages of these buildings may include corrosion resistance: all elements of the main bearing frame still in the factory are primed or coated with a corrosion-resistant coating. Due to the simplicity of the structures it becomes much easier to improve the fire resistance on site - in particular to cover the bearing structures with fire-protective paints. Besides, the high-strength steel itself is less apt to corrosion than ordinary construction steel.

  • Fast installation

    Tapered beams allowed to get rid of a large number of small structural and connecting elements typical for truss structures. In addition, the full range of frame elements is produced and completed at the factory. All this increases the speed of installation at the construction site. Thus an average installation time for a standard building makes 4 weeks, which is 1.5 times less than the time required for the construction of similar buildings on traditional technologies.

  • Reduced load on the foundations

    For 30 and 36 m spans a tie is supplied - an element that connects the extreme struts of hinged frame thus compensating for the lateral force that moves the foundations apart. This enables to transfer only vertical loads on the concrete that hugely reduces the cost of reinforced concrete works at the installation of foundations.

  • Savings in Transportation

    Unlike truss structures, tapered beams take little space, which reduces the costs of transportation to the construction site.
