Why choose our perforated metal sheets?
High Open Area for Better Airflow and Filtration
Round hole perforated metal typically achieves an open area of 30%–60%, depending on hole size and pitch.
Compared to slotted holes, round holes can increase airflow efficiency by 10–20% under the same thickness conditions.
Uniform Strength Distribution
Round holes distribute stress evenly across the sheet.
Circular geometry avoids stress concentration points, unlike square or slotted holes.
High Precision CNC Punching
We use CNC perforating machines with ±0.05 mm tolerance.
Ensures consistent hole size and spacing
Critical for filtration accuracy and visual consistency
