basic situation
In use, it is required to have good welding, riveting performance and comprehensive mechanical properties. The raw material billets for channel steel are carbon steel or low-alloy steel billets with a carbon content of not more than 0.25%. The finished channel steel is delivered after hot forming, normalizing or hot rolling. Its specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as 100*48*5.3, which means that the waist height is 100 mm, the leg width is 48 mm, and the waist thickness is 5.3 mm. Steel, or 10# channel steel. For channel steel with the same waist height, if there are several different leg widths and waist thicknesses, a b c must be added to the right of the model to distinguish them, such as 25#a 25#b 25#c, etc.

Channel steel is divided into ordinary channel steel and light channel steel. The specification of hot-rolled ordinary channel steel is 5-40#. The specifications of hot-rolled flexible channel steel supplied by agreement between the supply and demand parties are 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed panels, etc. Channel steel is often used in conjunction with I-beam.
Channel steel can be divided into 4 types according to its shape: cold-formed equal-side channel steel, cold-formed unequal-side channel steel, cold-formed inner-coiled channel steel, cold-formed outer-coiled channel.
According to the theory of steel structure, the channel steel wing plate should be stressed, which means that the channel steel should stand upright instead of lying on its stomach.

①Use international chemical element symbols and national symbols to represent chemical components, and Arabic letters to represent component content:
Such as: China, Russia 12CrNi3A
②Use fixed-digit numbers to indicate steel series or numbers; such as: the United States, Japan, 300 series, 400 series, 200 series;
③The serial number is composed of Latin letters and sequence, which only indicates the purpose.

Specification setting
The specifications of channel steel are mainly expressed in dimensions such as height (h), leg width (b), waist thickness (d), etc. The domestic channel steel specifications are from No. 5-40, that is, the corresponding height is 5-40cm.
At the same height, light channel steel has narrower legs, thinner waist and lighter weight than ordinary channel steel. No. 18-40 is large channel steel, and No. 5-16 channel steel is medium-sized channel steel. Imported channel steel indicates the actual size and relevant standards. The import and export orders of channel steel are generally based on the specifications required in use after the corresponding carbon steel (or low alloy steel) steel grade is determined. Except for the specification number, channel steel has no specific composition and performance series.
The delivery length of channel steel is divided into two types: fixed length and multiple length, and the tolerance value is specified in the corresponding standard. The length selection range of domestic channel steel can be divided into three types: 5-12m, 5-19m, and 6-19m according to different specifications. The length selection range of imported channel steel is generally 6-15m.
