Recently, the following trend has emerged: when constructing a structure (a shopping center, various sports facilities and complexes, bridges, communication towers, etc.), designers and architects prefer a profile closed pipe due to its practicality. Profile steel bent closed pipes and rectangular pipes have several important advantages: Increased corrosion resistance of metal structures (in comparison with other types of rolled metal); The time spent on assembling buildings and structures under construction is significantly reduced. The use of shaped pipes in the construction sector also makes it possible to erect large-span structures with high loads. At the same time, the weight of structures made of shaped pipes is lower, and the strength is high. Such parameters are achieved due to the uniform distribution of the load along the length of the entire profile.
