What is a steel channel?
A steel channel is one of the main types of rolled steel widely used in construction, mechanical engineering, and other industries. This profile has a P-shaped or U-shaped form, providing high bending strength and resistance to deformation.
Channels are made of carbon or low-alloy steel according to standards such as EN 10025. Depending on the type of shelves (with a slope or parallel faces), they are designated as type "P" and "U" channels.
Main types of steel channels
There are several types of channels that differ in their manufacturing method and technical characteristics. These types determine their application in various fields.
Hot-rolled channels
Manufactured by hot rolling from steel, providing high strength and durability. Such channels are used for the construction of load-bearing structures, bridges, and building frames. Their sizes vary from 50 to 300 mm in wall height.
Bent channels
Bent channels are manufactured from sheet metal, which is bent to the required shape. They are lighter than hot-rolled counterparts, making them ideal for lightweight structures. However, they are less resistant to vertical loads.
Channels with inclined and parallel shelves
Type "U" channels have inclined shelves, which simplifies their installation in structures. Type "P" channels with parallel faces provide uniform load distribution, which is in demand in mechanical engineering.
Technical characteristics of steel channels
The technical parameters of channels determine their area of application and capabilities in design. Considering their characteristics, you can choose the appropriate type for a specific task.
- Dimensions: wall height from 50 (e.g. M.bars 5P, 5U numbers) to 300 mm, shelf width from 32 to 115 mm.
- Weight: from 5 to 45 kg/m, depending on the size.
- Materials: carbon steel (St3) and low-alloy steel (S355).
- Length: standard (6–12 m) or non-standard length.
A table of dimensions and weights allows you to quickly select the appropriate profile for the project, minimizing material overspending.
Table of dimensions and weights of steel channels
| Channel height, mm | Weight per 1 linear meter, kg | Accuracy class | Standard |
|---|---|---|---|
| 100 | 7.1 | B, C | EN 10025 |
| 150 | 11.2 | B, C | EN 10025 |
| 200 | 15.3 | B, C | EN 10025 |
| 250 | 19.4 | B, C | EN 10025 |
| 300 | 23.5 | B, C | EN 10025 |
Application of Steel Channels
Channels find application in many industries due to their versatility and availability. Below are the main areas of use.
Construction
In construction, channels, such as channel 33, are used for the construction of frame structures, bridges and floors. They provide the necessary rigidity and resistance to loads.
Mechanical Engineering and Railcar Construction
Channels, including channel 40, are used to create frames, chassis and elements of railcars. Their strength characteristics allow them to withstand large dynamic loads.
Power Engineering
In the power industry, channels, for example, channel 50x50x3, are used for the construction of power line supports, structures for turbines and generators, and other objects operating in extreme conditions.
How to choose a steel channel?
The correct choice of channel depends on the project requirements and operating conditions. The main selection criteria include type, size, and material.
- For construction: Hot-rolled type "P" channels with a wall height of 100–200 mm are recommended for frame structures.
- For mechanical engineering: Type "U" channels made of low-alloy steel are suitable for frames and chassis.
- For lightweight structures: Smaller bent channels are used in finishing works and decorative projects.
- For energy: Channels made of S355 steel or analogues, resistant to corrosion and high temperatures.
It is also important to consider anti-corrosion treatment if the channel will be used outdoors.
