Channel steel (U-Profile) is one of the most widely used steel sections in construction and industrial applications, produced in a U-shaped design. It is available in both lightweight and heavyweight types, manufactured according to DIN, EN, and ISIRI standards.
Channel steel is commonly used in the construction of frames, metal structures, frameworks, machinery, and industrial projects. Its good resistance to pressure and impact, along with easy installation, cutting, and welding capability, makes it an ideal choice for various applications.
Selecting the proper size and steel grade ensures optimized performance and durability of the structure.
Steel channel (U-section) is a key element in constructing strong yet lightweight structures. Produced in various grades and dimensions according to international standards such as ASTM and DIN, it offers wide versatility for engineering applications.
Thanks to its high strength, bending resistance, and ease of processing, steel channel is extensively used in civil projects, industrial applications, steel frameworks, framing systems, and equipment manufacturing.
Applying a galvanized coating or anti-corrosion paint significantly enhances its durability and resistance in harsh environments, particularly in outdoor applications.
Channel steel (U-profile) is an open-section steel product widely used in the construction industry, including the production of reinforced steel shelves, beams, columns, trusses (rigid structures made of triangular units connected by slender components), and many other applications.
This steel product is manufactured through the hot rolling process with a U-shaped cross-section and is produced in various sizes.
The designation criterion for channels is based on the channel height in centimeters, which represents the external distance between the two flanges along its transverse axis. For example, a channel with a height of 6 cm is referred to as Channel No. 6.
From the perspective of shape, channels are produced in two types:
Parallel flange channels
Tapered flange channels
They are available in heights ranging from 3 to 40 cm and lengths between 0.3 to 12 meters.
Additionally, based on dimensions and weight, channels are classified into lightweight and heavyweight categories.
Most channels produced in domestic factories are of the lightweight type, with a lower weight than the ST37 UPN standard (Stahl standard).
Heavyweight channels, however, are manufactured with dimensions and weights equal to the Stahl standard, and are produced in certain domestic and European factories.
In this process, channels from size No. 8 to No. 18 are produced using the hot rolling method.
Rolling is one of the most common metal forming processes. In the hot rolling method, a steel billet (bloom) with a defined cross-section and length is first charged into reheating furnaces. After reaching the required temperature, the billet passes through the roughing stands (initial rolling mills), where its cross-section is reduced. Finally, after passing through the intermediate and finishing stands, the billet is shaped into a channel profile.
The finished channel is then cut to the desired length by a hot shear machine.
