Bent channel: application features
The bent channel is a metal product,similar to its section on the letter "P". This material consists of a wall and two shelves, which are located on one side. Usually the curved equal-channel channel is produced in lengths from two to twelve meters, while the wall thickness varies from 2.5 to 8 millimeters.
Feature of the product is its smallspecific gravity and at the same time high strength. The metal structures made of this rolled metal are easy to work with, and they are capable of withstanding significant loads.
From the hot-rolled bent channel is differentaccuracy of dimensions, and visually - the presence of external rounded corners. When manufacturing the product on roll forming machines, all defects in the workpiece are corrected, so further processing of the material is not required. Unlike hot-rolled profiles having uneven thickness, which negatively affects welding and other operations, the bent channel can be used without even removing the chamfer.
Relatively low cost of products in totalwith excellent strength characteristics allows us to use this metal in construction and industry, which ensures high economic efficiency.
The bent channel is widely used forreconstruction of buildings and for the construction of various facilities. Today, the metal structures in which this material is present constitute quite a serious competition with conventional (traditional) reinforced concrete structures.
This allows us to achieve a number of technological andeconomic advantages, reduce the complexity of installation work, and shorten construction time. For example, many engineers and builders pay attention to the variety of the channel, which is a galvanized thermoprofile, manufactured to individual sizes.
Also, the use of the material allowsto minimize the load on the structure, which in turn makes it possible to make the foundation of the building more simple. In addition, the bent channel has a high functionality and versatility, which makes it reasonable to use it in a variety of construction sites. The material is used for making the framework of facing of external or internal walls, the construction of partitions in production and residential / office buildings.
Another important area of application of the bentrolled metal is mechanical engineering. Channel bars are used for manufacturing various parts of mechanisms and machines, as well as for the construction of frame structures. From the material in the automotive industry, load-bearing frames for trucks are produced.
The bent channel, the assortment of which is quite diverse, is made on roll forming rolls of hot rolled carbon, structural or low-alloy steel.
Products along the length of the shelves are divided into equally and unequal bent channels, which are manufactured according to different GOSTs.
The assortment is also classified according to the accuracy of rolling (conventional, high and high-precision), in size and shape (with parallel faces, sloping, economical, lightweight, special).
