D12 / D20 / D35
Large mixed-diameter layout
Panel layout with mixed hole diameters, dimension notes, and factory drawing title block.
Irregular / B
Irregular Perforation Plan
Irregular perforation uses mixed hole diameters to reduce the mechanical feel of regular perforated panels. It is suitable for hotels, club spaces, and high-end offices requiring a softer acoustic surface.
Mixed Diameter
8/12/20 mm, 12/20/35 mm
Mixed hole sizes create a less repetitive surface rhythm.
Perforation Rate
9.8%-9.9%
Typical density supports acoustic function with softer visual expression.
Use Case
Hotel / Club / High-end office
Suitable for art-oriented walls and refined interior surfaces.
CAD Drawing
Irregular CAD drawings
1200 x 2400 factory CAD drawings show D12/D20/D35 and D8/D12/D20 mixed hole layouts.
D8 / D12 / D20
Small-medium-large layout
Mixed hole layout for a more natural acoustic surface and borderless detailing options.
Softer response
Mixed hole diameters reduce the regularity of a single-hole pattern while maintaining acoustic absorption.
Less mechanical expression
Random distribution is suitable for high-end interiors and art-oriented acoustic wall surfaces.
Density control
Boundary, blank area, and panel joint relationships should be checked to avoid uneven local density.
