The specifications of channel steel are mainly expressed by dimensions such as height (h), leg width (b), waist thickness (d), etc. Domestic channel steel specifications range from 5-40, corresponding to a height of 5-40cm.

At the same height, lightweight channel steel has narrower legs, thinner waist, and lighter weight than ordinary channel steel. 18-40 are large channel steels, while 5-16 are medium channel steels. Imported channel steel shall indicate the actual specifications, dimensions, and relevant standards. General import and export orders for channel steel

After determining the corresponding carbon steel (or low-alloy steel) grade, the specifications required for use shall prevail. Apart from the specification number, channel steel does not have a specific composition or performance series.

The delivery length of channel steel is divided into two types: fixed length and double length, and the allowable value is specified in the corresponding standards. The length selection range of domestic channel steel is divided into three types according to different specification numbers: 5-12m, 5-19m, and 6-19m. The length selection range for imported channel steel is generally 6-15m.

Galvanized channel steel is widely used in various building and engineering structures, such as beams, bridges, transmission towers, lifting and transportation machinery, ships, industrial furnaces, reaction towers, container racks, cable trench supports, power piping, busbar support installation, and warehouse shelves.
