Channel

Channel steel is a long - strip steel with a groove - shaped cross - section. It belongs to carbon structural steel for construction and machinery, and is a type of section steel with a complex cross - section, whose cross - sectional shape is groove - shaped. Channel steel is mainly used in building structures, curtain wall projects, mechanical equipment, vehicle manufacturing, etc. In China, the import volume of channel steel is greater than the export volume. The main production areas are several steel mills such as Tangsteel, Baotou Steel, Shandong Steel, Huangshi Special Steel, Magang, Xuanhua Steel, and Rizhao Steel.

technical parameters

Parameter

The executive standards for channel steel mainly include GB/T706 - 2016 and JIS G3101 - 2015.

GB/T706 - 2016 is a national standard in China, which is used to specify the dimensions, shapes, weights, and technical requirements of channel steel. For example, the executive standard for Q345D channel steel is GB/T706 - 2016. This type of channel steel has the characteristics of low - temperature resistance and high strength, and is widely used in petroleum supports and other applications. JIS G3101 - 2015 is the Japanese Industrial Standards for iron and steel materials. It has strict requirements for the chemical composition and mechanical properties of channel steel, ensuring the quality and stability of Japanese - standard channel steel. The JIS G3101 - 2015 standard also has detailed regulations on key technologies and indicators such as the allowable deviation of the cross - sectional height, the curvature, and the torsion angle of channel steel, ensuring the performance and quality of the product.
