History of the Development of LGS Structures
Although many consider cold-formed steel framing—LGS construction—to be a “new” building product, it has in fact been used in North America for over 100 years. The use of cold-formed steel elements in building construction began in the United States and England in the 1850s. During the 1920s and 1930s, the adoption of cold-formed steel as a construction material remained limited due to the lack of appropriate design standards, as well as the absence of material-specific guidance in building codes.

Today, the properties of LGS are utilized not only as a cladding system, but also as a complete building solution, replacing bricks and blocks with thin, galvanized steel profiles fastened together into frames to form both load-bearing and non-load-bearing walls—external (facade) and internal partition walls.
The most common sections are C-profiles. These typically range in size from 40 to 225 mm, with thicknesses between 0.56 mm and 3.2 mm, depending on whether they are used in external or internal applications, and whether the elements are load-bearing or non-load-bearing.
Prefabricated buildings – LGS system construction
“Prefabricated buildings” with LGS construction are built from the highest quality materials and in accordance with all norms and CE and ISO standards. The advantage of this System is that all buildings can be of different architectural design and “personalized” according to the Investor’s request and built in a short period of time.

Prefabricated elements (PREFABRICS) can be 2D prefabs and 3D prefabs.
2D prefabs are flat panels and are divided into:
1. Walls (facade and partition wall)
2. Intermediate floor constructions – mezzanine floor
3. Roof structures
Modular Construction – LGS System
Modular homes represent a subtype of prefabricated housing, i.e. one of the forms of prefabricated construction. They consist of individual sections—modules—that are manufactured in factory conditions, with up to 90% of the modular unit completed off-site.
A fully automated production line for LGS structures enables the creation of various module configurations, which can be combined and multiplied in different layouts to form complete buildings. In this way, “serial production of modules” is introduced, maximizing production efficiency and optimization.

Energy Efficiency – different types of walls
The main characteristics of the material and the structural system are distinguished by: high parameters of ENERGY EFFICIENCY, high fire resistance, high resistance to earthquakes and stability of the system, controlled origin of incorporated materials and attestation of all structural raw materials, quality and precision of production, compliance with the strictest biological and ecological criteria (excellent vapor permeability) EU quality and construction, high thermal insulation properties, excellent acoustic characteristics. This type of construction provides excellent wind resistance due to the careful preparation of static calculations, as well as better flood protection due to the possibility of easy replacement of the necessary damaged layers, which is an advantage compared to classic masonry construction.
