Carbon channel steel 

Channel steel is a long strip of steel with a groove-shaped section. It is a carbon structural steel for construction and machinery. It is a section steel with a complex section and its cross-sectional shape is a groove. 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, and cold-formed outer-coiled channel.

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 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.

Channel steel is a long steel with a groove-shaped cross section. The cross-sectional shape is a channel-shaped section steel. Channel steel is a carbon structural steel for construction and machinery. It is a section steel with a complex cross-section, and its cross-sectional shape is a groove shape. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing. In use, it is required to have good welding, riveting performance and comprehensive mechanical properties.
