In this article, Baowu will show you one of them - channel steel.

Channel steel is a long strip of steel with a groove-shaped cross-section. It is a carbon structural steel for construction and machinery. It is a section steel with a complex cross-section. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.

In use, it is required to have good welding, riveting performance and comprehensive mechanical properties. The raw material billets for producing channel steel are carbon-structured steel or low-alloy steel billets with a carbon content not exceeding 0.25%. The finished channel steel is delivered in hot-formed, normalized or hot-rolled state.

Channel steel is divided into ordinary channel steel and light channel steel.

At the same height, light channel steel has narrower legs, thinner waist and lighter weight than ordinary channel steel. No. 18-40 is a large channel, and No. 5-16 is a medium channel. Imported channel steel indicates the actual size and relevant standards. The import and export order of channel steel is generally based on the specifications required in use after determining the corresponding carbon steel (or low alloy steel) steel grade. Apart from the specification number, there is no specific composition and performance series for channel steel.

The advantages of channel steel mainly include the following aspects:

It's light weight. Since it is made of hot rolled steel sheet, it has the advantage of light weight. Compared with concrete, the structural planning is reduced, and the construction process is relatively simple;

It has good flexibility, scientific and reasonable internal structure and high stability. It can usually be used to accept large oscillations, and the ability to resist natural disasters is also relatively strong;

Save time and effort. In the welding process, materials can be significantly saved and a certain amount of manpower and material resources can be reduced. In the process of processing, it also has the advantages of easy processing, disassembly and recycling.

Therefore, it is widely used in the steel structure of purlins and wall beams, and can also be combined into building components such as light roof trusses and supports. It can also be used for columns, beams, arms, etc. in mechanical light industry manufacturing.

The above is the relevant content of channel steel. If you want to know more, please pay attention to Baowu at any time.
