The existing range of hot-rolled channels is regulated by GOST 8240-97 in accordance with the applied load.
Steel channel is a common subgroup of rolled metal products, produced in a wide range of products and in its shape on the section is a U-shaped profile, which determines its main properties and characteristics.
Depending on the characteristics of the channel application, in accordance with GOST, it differs in the grades of steel used, standard sizes and manufacturing methods, among which there are two main ones: the method of hot coining and cold bending. Accordingly, experts distinguish between hot-rolled and bent steel channels, while certain parameters of the finished product depend on the manufacturing method.
Currently, the metal channel is the most widely used in the construction industry and in industry, including used in the construction of various frames, prefabricated metal structures, etc.Due to its features, the channel can withstand a fairly significant load, so it can be used as load-bearing structures for various types of floors.
