304 stainless steel channel steel is a long steel strip with a grooved cross section, similar to stainless steel I-beam. Stainless steel channel steel is divided into ordinary channel steel and light channel steel. The model and specification are expressed as waist height (h) × leg width (b) × waist thickness (d), in millimeters. Its specification expression method, such as 120*53*5, means a channel steel with a waist height of 120 mm, a leg width of 53 mm, and a waist thickness of 5 mm, or 12# channel steel. Channel steels with the same waist height, if there are several different leg widths and waist thicknesses, also need to add a b c to the right of the model to distinguish them, such as 25a# 25b# 25c#, etc.

Stainless steel channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures. Channel steel is also often used in conjunction with I-beams.

1. Hot-rolled stainless steel ordinary channel steel (GB707-88): Mainly used for building structures, vehicle manufacturing and other industrial structures, often used in conjunction with I-beams.

2. Hot-rolled stainless steel light channel steel (YB164-63): A steel with wide legs and thin walls, which has better economic effects than ordinary hot-rolled channel steel. Its specifications range from 5-40#. The 1966 Metallurgical Standard stipulates that the specification range is from 10-40#. Main uses: for buildings and steel frame structures, etc.
