Q:What is the difference between C-shaped steel with 2 sets of punching and C-shaped steel with 3 sets of punching?

The difference between the two is that the location and number of punching holes are different.
C-shaped steel is a common building material, often used for building structures and supports. When making C-shaped steel, you need to punch some holes in it to facilitate its use. The location and number of these holes are usually determined based on specific usage requirements and design.
