The channel is a representative of high-quality, or rather, shaped metal products. At its core, this is a type of reinforcement that has found active use in construction, heavy engineering. With the help of the channel bar, bridges and roads, city high-rise buildings and suburban buildings are erected, machines and vehicles are manufactured.
The channel is a steel profile with a cross-section in the form of the Russian letter "P". This sectional shape was not chosen by chance: it provides the highest level of adhesion of surfaces, which is extremely important when erecting various supporting structures. The channel gives them the strength, reliability and durability demanded during operation.
It should be noted that this type of rolled metal, due to the characteristics of the feedstock, is used much more often than its reinforced concrete counterpart. The latter "copes" worse with deformation loads, withstands the effects of corrosion and temporary wear.
About raw materials and production methods
According to GOST, the channel is made from hot-rolled or cold-rolled carbon steels of normal quality. In the northern regions, metal products made from low-alloy steels with manganese and carbon impurities are often in demand. Products of this rank can withstand harsh climatic conditions.
According to the production method, the channel is classified into cold-formed and hot-rolled. Externally, the bent version is distinguished by rounded outlines of the shelves. Such a channel is produced on a roll-forming mill.
A hot-rolled channel, like many other rolled metal products, is helped by a steel sheet and a rolling machine. Channel (bent and hot-rolled) is also distinguished by the width of the shelves, the length.
What to consider when buying a channel bar
