Channel

The specifications of channel steel are mainly distinguished by its size parameters, including but not limited to key dimensions such as height (h), leg width (b), waist thickness (d).

Small channel steel: generally refers to channel steel with a height between 50mm and 100mm.
Medium channel steel: The height range is roughly between 120mm and 180mm.
Large channel steel: usually refers to channel steel with a height of more than 200mm.
