Purpose. For the production of light load-bearing structures in industrial and civil buildings, construction.
Scope. Construction industry enterprises manufacturing modern metal structures.
Advantages. The closest analogue of this design is a steel beam with a double transversely profiled wall with bent channel belts (the main disadvantage is the increased material consumption due to the double wall), which in comparison opens up a number of significant advantages of the developed structural form of the beam, namely, obtaining a structure with a smaller amount of metal, which ensures a significant reduction in material consumption by up to 10%.
Description. The peculiarity of this design model is the use of a single profiled wall of trapezoidal outline and a smaller number of self-tapping fastening screws, which significantly reduces the cost of materials and the labor intensity of manufacturing the structure.
