As a professional perforated metal manufacturer, we supply high-quality round perforated metal sheets with custom specifications for industrial filtration, ventilation, and architectural applications.
We offer "Ready-to-Install" Round Perforated Metal solutions, including precision bending, laser perimeter cutting, and welding.
| Feature | Specification | Why it matters |
| Material | SS304/316, Aluminum, Galvanized | Ensures durability in specific environments. |
| Hole Diameter | 0.5mm - 50mm (Customizable) | Meets precise filtration/ventilation needs. |
| Open Area | 30% - 65% | Balances airflow with structural strength. |
| Edge Margin | Default 20mm or No-margin | Facilitates easy welding and framing. |
| Standard | ASTM E674 / ISO 9001 | Guarantees international quality consistency. |
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.
Round holes distribute stress evenly across the sheet.
Circular geometry avoids stress concentration points, unlike square or slotted holes.
We use CNC perforating machines with ±0.05 mm tolerance.
Ensures consistent hole size and spacing
Critical for filtration accuracy and visual consistency
