It is the Swiss cheese of metal fabrication. Manufacturers make dryer drums, HVAC components, lawnmower mufflers, architectural façades, and just about anything in between out of perforated metal. Creating perforated parts is a common practice among job shops and OEMs alike, as any type of finished part or product that needs air circulation or heat release requires perforated metal to deliver that result.
