Steel Channel

Stud or U profile is one of the branched steel sections with an open section, which is used in the construction industry, including the construction of strong steel shelves - beams - columns - trusses (a rigid structure of triangular units, which is made by connecting narrow and tall components etc.) It has many uses. This steel product is produced through the hot rolling process with a U-shaped cross-section and different sizes.
 The standard for naming studs is the height of the stud in centimeters, which shows the external distance between the two wings on the transverse axis. For example, if the stud height is 6 centimeters, it is called grade 6 stud.

In terms of appearance, studs are produced in two types with parallel wing and inclined wing from 3 to 40 cm in height and 0.3 to 12 meters in length.

Also, studs are divided into light and heavy categories based on dimensions and weight.
 The studs produced in most domestic factories are of light type and weigh less than the standard.

Heavy studs have the same weight and dimensions as the Stall standard, which are produced in some domestic factories.

In this activity, studs grade 8 to 18 are produced by hot rolling method.
Rolling is one of the common methods of shaping metals. In the hot rolling method, first the steel billet with a specific cross-section and length is rolled into the thermal furnaces, and after reaching the required temperature and passing through the primary rolling racks (set of rollers), its cross-section is reduced. It is found that by passing through the middle and end rolling racks, it is converted into a stud shape and then it is cut to the appropriate length by hot scissors.
