Assembladge and installation of frames are carried out in accordance with installation drawings drafted by our Company. Each component of a frame is individually marked in series and bears data regarding panel / truss name it belongs to. Each panel / truss is delivered along with assembling manual. Mentioned document includes information about assembling sequence, and their layout. After assemblage of panel / truss installation manual could be used for further direction regarding installation sequence of walls, floorings and trusses.

Screwdriver, general assembly drawings and tapeline are thing you need to assemble our frame.


brace to studAssemblage of structural elements is enjoyable process, it reminds playing the LEGO construction set and awakens your desire to build something special and colossal.

All components of a frame could be interlocked (particular sound shall be heard) through the preperforated holes and tightened with the help of screws. Functional capabilities and opportunities of our equipment ensure easy throughout interconnection of frame components with identical cross-section over the cut of profile wall.intersection

Cutting of edges maintaining 45° angle provides opportunity to connect two profiles if it is needed to place bracing or inclined connectors.

Bolt and triple holes are used for joining of panels and girders. They are also used for centering and eliminate rigorous work using measurement devices.

3 in 1Joint optimization technology enables connection of up to three profiles at a single point.

Our structures could be installed at any time of the year. Snow, rain, adhesive freeze or baking sun could not prevent you from installation works. Our fames will save your time planned for Project implementation.

Our company offers preliminary assembling services. It saves overall installation time at the construction site and facilitates handover of facilities

More about LGSF construction stages.


1.Preparation of Understructure. Average weight of a structure when applying the LGSF technology is from 25 to 35 kg per one square meter of structure’s floor. This simplifies the base structure required and decreases understructure construction costs for 1.5 — 2.5 times. However, it is essential to maintain precise parameters of understructure, errors in geometrical dimensions shall be minimal. Accuracy of produced frame is 1 mm, consequently frame installation will reveal any misalignment of understructure.

Understructure design and its installation methods are predetermined by geographic location of building, soil structure stability, terrain and other aspects. Strip foundations are the most popular ones due to their installation on concrete blocks; formed concrete foundation is frequently used as well. Sometimes they are used directly on natural soil. The LGSF could be installed on pile foundation. Structures from LGSF are lighter – fewer materials are needed for their installation, consequently, they are less time and labor consuming solutions.

The LGSF is resistant to earthquakes up to 9.5 point of Richter scale and properly withstands both wind loads and precipitations.

2.Installation of Frame. Assembled wall panels or trusses shall be placed on understructure and fixed with anchors. Panels are connected with screws (in accordance with joints provided in developed design). The following installation sequence shall be followed:

  • Outer angles of the first floor walls
  • Wall panels joining the angles of the first floor walls
  • Girders/panels of the first floor flooring
  • Separate elements of ceilings and floors (depending on the site)
  • The 2-nd floor shall be assembled by analogy with the 1-st one
  • The 3-rd floor shall be assembled by analogy with the 1-st and the 2-nd ones
  • Installation of roof or attic floor roof structure

Windows and doors are installed to assembled walls. When the frame is assembled, walls are covered with heat-insulating material, girders of floorings and roof are also filled in with heat-insulating material.

3.Installation of Building. The LGSF frame includes openings for water supply pipes and electric wiring.

Since the entire frame of a building is filled and coated with sound or heat insulation, all communications shall be installed before commencement of finishing works. Particularly, it is important to lay pipes, cables and communications before the final finishing of a building. It is recommended to place all communications in a frame. If pipelines shall be laid in floor, wall coating works could be performed without preliminary laying of pipelines. Still, it is required to foresee place for pipes inside the walls.

4.Assemblage of a Roof. The LGSF frame structure could be used as a roof structure. It is designed and produced in order to construct almost all types of roofs. Building of a roof using LGSF frame is quick and easy; it helps to maintain ideal dimensions and absolutely plain surface. Roof girders are lightweight and could be installed without heavy equipment.

5.Installation of Floorings. Installation of floorings of LGSF frame structures is precise, quick and easy even without heavy equipment. Space of flooring girders is used for installation of required communications.

Top and bottom parts of the flooring could be easily finished. The upper layer could be formed using OSB fixed to the structure. For the bottom part it is recommended to use fillets that are bolted to flooring girders and form the base for a sound insulation layer. When WFB are fixed, you could use any type and form of the ceiling (for example counter ceiling). If you want to install under-floor heating – just fixed the shaped sheet to the flooring and form concrete layer including tubes/cable of heating system.

6.Interior Walls and Partitions. Upon insulation of all exterior walls of the LGSF frame structures and laying of communications, water supply and electric networks and mains the interior walls and partitions could be installed.

Gypsum plasterboard bolted to the structure in one or two layers is used for walls and partitions. The OSB or plywood could be used instead of the first layer of gypsum plasterboard. Such walls could hold elements of furniture without additional fixing elements. The WFB could be used instead of OSB or plywood; it would enhance sound insulation level. Spaces between sections could be filled in with rock-wool or other sound insulating material. Decorative floor covering could be laid when all walls, partitions and the under-floor are installed.
