Introduction of Hot Rolled Channel Steel

The channel steel is a long strip of steel with a groove shape. The specifications are expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as 120 * 53 * 5, indicating a waist height of 120 mm, a leg width of 53 mm, and a waist thickness of 5 Millimeter channel steel, or 12# channel steel. If the waist height is the same, if there are several different leg widths and waist thicknesses, add a b c to the right of the model, for example, 25a# 25b# 25c#.

Parameter of Hot Rolled Channel Steel

The channel steel is a long strip of steel having a groove shape in cross section. Like the I-beam, the channel steel is also divided into two types: ordinary channel steel and light channel steel. The model and specification are also expressed in millimeters of waist height (h) * leg width (b) * waist thickness (d), such as 120 * 53 * 5 channel steel, that is, waist height 120mm, round steel, need to be on the right side of the model Add a, b, c, etc. to distinguish. Usually, the channel steel is expressed in centimeters of the waist height, and the above channel is called 12# channel steel.

The channel size range is 5-40#. Requirements including including and marking shall be implemented in accordance with the provisions of GB2101-80.

Classification of Hot Rolled Channel Steel

1.Hot rolled ordinary channel steel (GB707-88)

Main application: Ordinary channel steel is mainly used in building structures, vehicle manufacturing and other industrial structures, often used in conjunction with I-beam.

2.Hot rolled light channel steel (YB164-63)

Hot-rolled light channel steel is a steel with a wide leg and a thin wall, which has better economic effect than ordinary hot-rolled channel steel. Its specifications range from 5-40#. In 1966, the specifications of the standard were from 10-40#.

Main application: construction and steel frame structure.
