The form of the middle slot has been standardized. At present, there are three forms: single chain, double chain and medium double chain. The length of the middle groove is determined according to the width of the support, most of which are 1.5m and 1.75m.

There are three types of channel side steel: D-shaped, E-shaped and M-shaped.
