The LSTK technology (light steel thin-walled structures) provides for the possibility of conducting installation work both in summer and in winter. Unlike wet process technologies, our technology does not include interruptions, shutdowns or temperature restrictions.

With the use of our frame structures, it is possible to create a free layout and implement a wide variety of architectural solutions.

Due to this indisputable advantage of the LSTK construction, we successfully use them in the course of the reconstruction of buildings, increasing their number of storeys. That does not create a significant load on the existing foundations. For new buildings, this property of our designs can significantly reduce the cost of building foundations.

In the modern construction community, since the 1950s, there has been a need to increase the speed of building of structures. Classical construction technologies have been supplemented by the ability to use thin-walled profiles of various geometric shapes, produced by the method of continuous profiling of steel strip. Such groups of profiles formed the basis for the creation of a technology called LGSF (Light Gauge Framing System). Canada is considered to be the birthplace of this technology, but it has become widespread and actively used in the Scandinavian countries and on the territory of modern Europe.

The technology has found its application in the construction industry for the building of both residential buildings with up to 5 floors and in industrial construction. The most popular architectural forms are superstructures on buildings with weak foundations for classical technologies, load-bearing structures for roofs and interfloor ceilings, small architectural forms and elements of ventilated facades. In addition, profiles are actively used in many other areas of life, such as the automotive and aircraft industries.

The basic principles of constructing structures based on LGSF technology is the calculation of the load-bearing capacity using the “end element method”. In the production of such elements, are used almost all grades of steel that have the ability to be turned by pressure. However, design rules clearly regulate the use of structural steel grades, for example S280-450GD with high-quality anti-corrosion coating 275–500 grams/m2. Such rules are not accidental. The use of thin-walled sheets from 0.7 mm to 4 mm necessarily increases the requirements for local stability and local deformations of nodal connections and directly used profiles.
