When we use the perforated metals, we will consider the ratio between hole and pitch size in perforated metal. Pitch is the center to center space.

The balance between holes and pitch in a metal sheet can affect the strength and efficiency in different usage.

While the variations of hole and pitch sizes are virtually countless, the general rule is that metal thickness should not  exceed either the hole size or pitch size.

To choose the right perforated metal pattern, you may have to consider some key factors.

The strength, application and arrangement of holes and pitch in perforated metal all have an effect on its functionality and efficiency.
