Purpose. For the manufacture of lightweight load-bearing structures in industrial and civil buildings, construction.
Application area. Construction industry enterprises manufacturing modern metal structures.
Advantages. Compared to the closest analogue (a steel beam with a double transversely profiled wall with bent channel belts), the presented design has a single profiled wall of a sinusoidal configuration, which reduces steel consumption and provides stability in the longitudinal and transverse directions of the beam. The use of such a structural form of the beam allows you to reduce the weight of structures by 40-60% without losing strength, stability and reduce the level of labor costs for the manufacture of this type of structure.
Description. The beam consists of a single profiled wall, sinusoidal in shape, which is secured with self-tapping screws to the belts in the form of bent or rolled channels. Support ribs (welded stamps) are attached to the belts by welding, and the wall is attached with self-tapping screws. This design has improved material consumption, cost and labor intensity.
