Channel is one of the steel sections that is included in the profile category. This profile consists of a horizontal surface called John and two vertical surfaces called Wings.
Definition of Channel:Channel is one of the steel sections that is included in the profile category. This profile consists of a horizontal surface called John and two vertical surfaces called Wings.
Channel which are steel, galvanized, aluminum and stainless steel. This product is available in the market at different prices based on the type of product.
The use of Channel in building construction started from the beginning of the 20th century and was used as one of the important steel sections in the construction industry during the First World War. After the Second World War, steel manufacturing factories expanded more and because of this, the production of steel and channel increased.
With the growth of the use of metal structures in the building, the demand for steel products increased, and for this purpose, manufacturers began to produce many steel sections, especially channel.
Types of Channel
Channels are generally classified into different types in terms of production process and appearance. If we categorize Channel production process, we must mention the following:
Types of Channel in terms of production process
Channels are divided into two categories in terms of the production process, but before they are separated in terms of production, the Channel that are produced from 3SP equivalent to ST37 have more flexibility and can be bent and welded on it more easily.
One of the advantages of Garm Felez Industries is that it uses this type of steel ingot in the production process, and this increases the quality and excellence of the products of Garm Felez Rolling Industries, which is marketed under the brand name “Joya Navard”. The products of this company can even be exported to European markets due to having good quality standards.
According to the production process, Channels are divided into two general categories:
The process of producing Channel is that heated raw ingots are produced by passing through rollers known as rolling.Depending on the size of the rolls, the Channel come out of the production line with the same size, which are called fabric Channel.
Pressed Channel, as the name suggests, are produced by pressing sheets of 6 and 12 meters in length. These types of Channel may be registered in different sizes according to the customer’s order.
Pressed Channel are used in various industries according to the sheet from which they are made.From this type of Channel, because of the appearance and to make the edges that need to be smooth It is also used in construction
Types of Channel in terms of appearance
Apart from the production process, the types of Channel can be classified according to their appearance:
Normal Channels are used in construction and industrial industries. Normal Channels vary in different sizes from 8 to 16. The height of this type of studs is from 30 mm to 400 mm, and the height and dimensions of this type of product depend on the customer’s needs.
Normal Channels can be produced in different sizes depending on the type of customer. Normal Channels are used in the base and frame of industrial devices, truck room, frames, etc.
Mesh Channels are produced from galvanized sheet. Holes are installed on the surface of the sheet of this Channel, which can be used for necessary things such as fastening bolts and nuts. Mesh channels are used in the construction of metal shelves.
A light Channel is a type of Channel which weight is less than the weight defined in the standard table of Stahl, and usually this Channel model is produced to the customer’s order.
In terms of weight and dimensions, heavy Channels are completely equal to the sizes recorded in the Stahl table. In general, heavy Channels are produced based on the sizes recorded in the calculation table in a number of domestic factories in the country as well as in some European countries.
In general, it can be said that light and heavy Channel have fundamental differences in dimensions, weight, Stahl pattern, price and even application. The final price of light and heavy Channel is also measured based on criteria such as weight, size, etc.
According to different applications, Channel have many features, which are mentioned below:
The low weight of the metal frame
Being efficient in the long time
High installation speed in buildings
Occupying little space
Resistance to steel tension
Common Channel standards
As it was said, Channels are defined in terms of application in two forms, C and U. In the construction of this steel section, two standards UPE and UPN have been considered. The difference between these two standards is in the wings used in each of them. The UPE standard has parallel wings and is considered for the C Channel; While the UPN standard has conical wings and is used for U Channels. These two defined standards are used in our country and the use of this product in other countries is defined by its own standards.
Common applications of Channels
Channels are used in various industries such as automobile manufacturing and construction. Perhaps the main use of Channels in various industries is that they are used for the purpose of the base and frame. In the construction of steel structures, such as steel bridges, Channels are used a lot. In general, the most important applications of Channels include the following:
Construction of the facade of the building
Construction of naval structures
Using Channel as beams or columns
in the manufacture of machinery
Garm Felez Rolling Manufacturing Industries Group was established in 1994 as a legal entity with the name of Ata under the official license of the Department of Industries and Mines of Tehran Province with the number 33377, aiming to manufacture all kinds of steel sections (hot rolling). Since 1995, it was registered with the name of Garm Felez Manufacturing Industries Company in the Company Registration Office of Tehran Province under registration number 156958.
