What about the specification of channel steel?
Channel steel is a strip of steel with a cross section. The commonly used model length is divided into 6 meters, 9 meters, 12 meters.
The specifications are expressed in millimeters of height (H) * leg width (b) * waist thickness (d), such as 80*43*5, which means waist height is 80 mm, leg width is 43 mm, waist thickness is 5 mm channel, or 8# channel steel.
The same height of the channel, if there are several different leg width and waist thickness, also need to add a B C on the right side of the model to distinguish, such as 25a#, 25b#, 25c# and other meters.
