Channel

Channel steel is a strip with a grooved section. The specification is expressed in mm of waist height (h) * leg width (b) * waist thickness (d). For example, 120 * 53 * 5 means that the waist height is 120 mm, the leg width is 53 mm, and the waist thickness is 5 mm, or 12 # channel steel. For channel steel with the same waist height, if there are several different leg widths and waist thicknesses, add a b c on the right side of the model to distinguish them, such as 25a # 25b # 25c #.

1. Channel steel classification

Channel steel can be divided into 4 types according to shape: cold-formed equal edge channel steel, cold-formed unequal edge channel steel, cold-formed inner lipped channel steel, cold-formed outer lipped channel steel

2. Common application of 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 large channel steel, and No. 5-16 is medium channel steel. Imported channel steel shall be marked with actual specifications, dimensions and relevant standards. The import and export ordering of channel steel is generally based on the specification required in use after the corresponding carbon steel (or low-alloy steel) grade is determined. Except for the specification number, the channel steel has no specific composition and performance series.

3. Channel steel development history

China's channel steel imports more than exports. It can be divided into two channels: simple import and import with complete set of projects. In recent years, several major coastal ports (Dalian, Tianjin, Qinhuangdao, Lianyungang, etc.) in China have been building and expanding automatic handling projects for oil, coal, grain and other bulk import and export commodities. With the introduction of main equipment, the import volume of large channel steel is also increasing. The main producing countries and regions are Japan, Russia and Western Europe. Channel steel for export is mainly exported to Hong Kong and Macao.
