With the development of repair and construction technologies, many modern structural materials have appeared that combine such indispensable qualities as high strength, lightness and low cost. Among such materials, one of the honorable places is occupied by U-shaped profiles, which got their name from the cross-sectional shape, which resembles the Russian letter āPā.
The advantages of metal profiles
Metal profiles (channels) have excellent performance characteristics. They are reliable and durable, and a variety of sizes allows you to use them not only in the repair and construction industry, but also in many other areas.
Most often, U-shaped profiles are made of galvanized steel or aluminum. Aluminum is an amazing material that combines high strength and lightness, making aluminum channels 8 times lighter than their steel counterparts. This property allows you to minimize the load of the structure, while maintaining a high level of quality.
Despite the fact that profiles are produced in different sizes (in width and height of shelves), they have one common important feature - metal sheets of minimum thickness are used for their manufacture. Nevertheless, the geometry of the profile provides it with high strength characteristics; therefore, U-shaped profiles successfully fulfill the functions of run and load-bearing elements of various designs.
Due to the absence of internal cavities in such profiles, rather complex structures and systems can be created from them.
U-profile production
The U-shaped galvanized profile is made of
rolled galvanized steel at special profile-rolling plants. The release of these products is carried out in strict accordance with the technical requirements of the current GOST.
The U-shaped aluminum profile is produced by pressing a special aluminum alloy with a high-grade chemical composition. Naturally, such profiles also comply with state standards.
Sizes
Since equal-channel channels are produced in various sizes, in the process of their production each variety is assigned a specific number that indicates the distance between the external shelves of the profile. According to the assortments adopted by GOSTs, in terms of profiling accuracy, U-shaped profiles are made of ordinary (B), high (B) and high (A) strengths. The cross-sectional dimensions of the profiles can vary in height from 25 to 410 mm, in the width of the shelves - from 20 to 180 mm and in thickness - from 1 to 8 mm.
Scopes of equal channel channels
The range of applications of the described product is wide enough. These products are used in the repair and construction industry as butt or load-bearing elements (reconstruction of buildings, wall decoration, installation and facing works, construction of partitions, etc.). Galvanized and aluminum channels are simply indispensable in the production of a wide variety of curtain rods, all kinds of exhibition and trade equipment, frames for advertising signs and billboards, interior items, and box structures. U-shaped profiles are also used as edging material. Even the high-tech aircraft industry is not complete without the use of
aluminum anodized U-shaped profiles.
Any designs from U-shaped profiles are very light, but are characterized by excellent indicators of rigidity and strength. The plastic properties of this material allow it to be used for the manufacture of structures of various shapes.
U-shaped profiles are divided into several main categories:
- general purpose;
- electrical engineering;
- for building structures.
