Channels are among the open profiles that are widely used in the construction of foundations and structures. Industrial and construction channels are profiles that are geometrically similar to the English U. The channel’s cross-section consists of one horizontal core and two vertical wings. Types of channels include UPE and UPN; the difference between the two is in the appearance of the wings. The UPE wings are flat and parallel, while the UPN-type wings are conical. There is another type that is thicker and heavier in weight, which is called European channels or UNP. This type is commonly used in large and industrial projects. Another type of classification is based on their appearance, which is offered in two types, simple and mesh. The simple type, which is often used in the construction of load-bearing stairs, is available in sizes 8, 10, 12, 14 and 16 and is produced in various heights, which usually varies between 30 and 400 mm. This type has two types of industrial and construction. However, the mesh type is usually used in the production of steel shelves.
