The perforated sheet punching process involves creating regular or specific patterned holes on metal sheet materials. This process enables the sheet to be used for ventilation, filtration, decorative, or structural purposes.

In brief, it can be summarized as follows:

• Perforated sheet: A metal sheet with holes punched into its surface.
• Punching process: Performed using mechanical press machines or technologies such as laser or plasma cutting.
• Hole shapes: Commonly circular, square, elongated (slot), or hexagonal.
• Areas of use: Widely used in architectural applications, the food industry, automotive, ventilation systems, furniture, and many other sectors.
