What are the main specifications and uses of channel steel?

In the field of construction and engineering, channel steel, as an indispensable steel material, is widely used due to its unique shape and excellent mechanical properties. Channel steel not only provides stable structural support, but is also easy to install and customize, adapting to various engineering needs. So, what are the specifications and uses of channel steel? This article will provide a detailed analysis for you.

The Main Specifications of Channel Steel

The channel steel is a long strip of steel with a cross-section in the shape of a groove. It is a steel shaped with a cross-section in the shape of a groove. In the specification table of channel steel, the specifications of channel steel are mainly represented by dimensions such as height (h), leg width (b), waist thickness (d), etc.

For example, 100485.3 represents a channel steel with a waist height of 100mm, a leg width of 48mm, and a waist thickness of 5.3mm, also known as 10# channel steel. If there are several different leg widths and waist thicknesses for channel steels with the same waist height, they also need to be distinguished by adding abc at the end of the model number, such as 25#a, 25#b, 25#c, etc. Currently, domestic channel steel specifications range from 5-40, corresponding to heights of 5-40cm.

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

The Uses of Channel Steel

Channel steel belongs to the carbon structural steel for construction and machinery, and is a complex section steel material with a cross-section in the shape of a groove. Channel steel is mainly used in construction structures, curtain walls, machinery and vehicle manufacturing, etc. It is required to have good welding, riveting performance and comprehensive mechanical properties in use. The raw material of channel steel is carbon content of not more than 0.25% carbon structural steel or low alloy steel.

The finished channel steel is shaped by hot processing, normalizing or hot rolling, and delivered in the delivered condition. The length of channel steel is divided into two kinds of fixed length and multiple length, and the allowable range is specified in the corresponding standard. Domestic channel steel has a length selection range of 5-12m, 5-19m, and 6-19m according to different specifications. The length selection range of imported channel steel is generally 6-15m.
