The technology of light steel thin-walled structures (LSTC) is widely used in the construction of warehouses, industrial buildings, trade pavilions, hangars, residential buildings and other facilities. Its popularity is explained by its high installation speed, low weight of structures and long service life. For those who are planning to buy an LSTK profile, it is important to understand what types of profiles exist and what tasks they are intended for.
LSTK profiles are made by cold bending from galvanized structural steel. The protective zinc layer provides resistance to corrosion, and high production precision allows you to quickly assemble the frame without additional adjustment of the elements. Due to its low weight, the load on the foundation is reduced, which reduces the cost of construction and reduces the time required to complete the work.
Main types of LSTK profiles
For the manufacture of frames, various types of profiles are used, each of which performs a specific function.
- C-shaped rack profiles;
- U-shaped guides;
- Z-shaped profiles for purlins;
- Σ (sigma) profiles for structures with increased load-bearing capacity;
- thermoprofiles to reduce heat loss;
- head profiles for installation of facing materials.
By combining different types of elements, you can create frames of almost any complexity - from small outbuildings to large industrial structures. The manufacturers' catalog usually presents profiles of various thicknesses, heights and configurations, which allows you to choose the optimal solution for a specific project.
Advantages of LSTK technology
One of the main advantages of LSTK is the speed of construction. All elements are manufactured in production with high precision, marked and delivered to the site ready for assembly. Installation is carried out primarily using bolted connections without welding, which allows construction to be carried out almost at any time of the year.
In addition, the structures are characterized by high strength with relatively low weight, corrosion resistance, fire safety and long service life. The use of thermal profiles helps reduce the formation of cold bridges and increase the energy efficiency of the building.
What to look for when choosing
When selecting a LSTC profile, it is recommended to take into account the thickness of the metal, steel grade, profile height, quality of galvanization and compliance of the product with the requirements of current standards. The accuracy of the geometry of the elements is of no small importance, since the speed of installation and the reliability of the finished product depend on it.
