Height: The height of C-shaped steel generally ranges from 100mm to 300mm, and the specific height depends on different uses and load-bearing capacity.

Width: The width of C-shaped steel generally ranges from 60mm to 150mm, and the specific width also depends on different uses and load-bearing capacity.

Thickness: The thickness of C-shaped steel generally ranges from 0.5mm to 3.0mm, and the specific thickness depends on different uses and load-bearing capacity.

In addition, the specifications of C-shaped steel can be further subdivided into specific sizes, for example:

• Length	Width	Thickness
  41	21	0.5~2.5
  41	41	0.5~2.5
  41	52	2.0~3.0
  41	62	2.0~3.0
  41	72	2.0~3.0
  41	82	2.0~3.0
  Finishes:	Electro-galvanised	Hot-dip galvanised	Zinc-aluminium-magnesium
