What are the specifications of channel steel?
The delivery length of channel steel is divided into two types: fixed length and double length, and the tolerance value is specified in the corresponding standard. The length selection range of domestic channel steel is 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.
The specifications of channel steel are mainly determined by height (h), leg width (b), waist thickness (d) and other dimensions.
At the same height, light channel steel has narrower legs, thinner waist and lighter weight than ordinary channel steel. No. 18-40 are large channel steels, and No. 5-16 channel steels are medium-sized channel steels. Imported channel steel is marked with actual specifications, dimensions and relevant standards. The import and export orders of channel steel are generally based on the specifications required for use after determining the corresponding carbon steel (or low alloy steel) steel grade. Apart from specification numbers, channel steel does not have a specific composition and performance series.
