Perforated Aluminum Panel

E Expert Experience

I've worked with perforated aluminum panels on some of the most demanding projects in the Gulf—Dubai Metro Red Line extensions, Riyadh King Khalid International Airport expansions, and Singapore's Changi Terminal 2 retrofit. What separates a quality perforated panel from a bad one is burr-free edges, consistent hole diameter across the entire sheet, and proper panel flatness after punching. We use servo-driven CNC turret presses with optical axis calibration that maintains ±0.1mm positioning accuracy. For acoustic applications, we precision-calculate the open area ratio (POR) needed to hit your target NRC (Noise Reduction Coefficient)—typically 0.70–0.90 for ceiling baffles. For sunshade facades, we use computational fluid dynamics (CFD) to validate wind load reduction before production. Every project gets a perforated panel sample mockup approval before mass production.

T Technical Specifications

**Core Specifications:**
• Base alloy: AA1100 / AA3003-H24
• Panel thickness: 1.5mm – 4.0mm (gauge selected per open-area and wind load requirements)
• Hole diameter: 1.0mm – 20.0mm (standard) / custom geometry
• Open area ratio: 3% to 70% (calculated per acoustic/wind requirements)
• Hole patterns: Round, square, slotted, hexagonal, custom artistic CAD patterns
• Edge quality: Deburred, no surface cracks (50x magnification inspection)
• Flatness tolerance: ≤1.5mm/m (EN 1396)
• Surface treatment: Powder coat / PVDF / anodizing
• Fire rating: A2-s1,d0 (EN 13501-1) available
• Acoustic data: NRC 0.70–0.90 (tested per ASTM C423 in reverberation room)

**Pattern Flexibility:** We accept DXF, DWG, or PDF drawings. Complex artistic patterns (logos, geometric art) require vector files. We provide 3D render visualization before production.
