A fish scale perforated plate is made by continuously punching a fish scale pattern on a CNC punching machine using a special mold, with specific spacing. These plates are mainly used in dryers and grain storage ventilation systems. 

When used in dryers, the fish scale perforated plate helps change the airflow direction and ensures even distribution. In grain storage ventilation, it ensures proper airflow without letting any grain escape.
