Perforated Metal Panels for Ventilation Applications
Perforated metal panels are decorative metal sheets made from aluminum alloy, stainless steel and other metals, processed with CNC punching to create hole patterns. Combining decoration with functionality, they offer ventilation, lighting, noise reduction and sunshade effects. Hole shape, size and arrangement are customizable, widely used in building facades, ceilings, partitions and other applications.

Production Process
01
Cutting & Leveling
Metal sheets are cut to design dimensions and leveled to ensure flatness.
02
CNC Punching
CNC punching is performed according to hole shape, size and arrangement to ensure hole position accuracy.
03
Deburring
Grind the sheet and hole edges after punching to remove burrs and improve surface texture.
06
Final Inspection
Check hole position accuracy, sheet flatness and surface finish before delivery.
05
Surface Treatment
5.Spraying, anodizing, etc., to enhance corrosion resistance and decoration.
06
Final Inspection
Check hole position accuracy, sheet flatness and surface finish before delivery.
Application scenario
Perforated curtain walls, sunshades, and ventilated exterior walls for building facades.
Interior ceilings, feature walls, sound-absorbing walls, and partitions.
Public buildings such as theaters, stadiums, airports, and high-speed rail stations.

FAQ
1
Q: Can hole shapes and arrangements be customized?
Yes, various hole shapes (round, square, slotted, etc.) and arrangements (matrix, staggered, gradient) are available.
2
Q: What about the sound insulation performance?
A: Good noise reduction can be achieved by adjusting the open area ratio and adding back sound-absorbing materials, suitable for acoustic projects.
3
Q: Will outdoor perforated panels deform?
A: Proper sheet thickness and stiffener design, combined with surface treatment, ensure no deformation during long-term outdoor use.
