Reinventing the balance of acoustics, aesthetics and functionality with precision perforation technology

I. Product matrix: accurately matching different spatial needs

1. Perforated plasterboard

Key Advantages: Lightweight yet strong (unit weight ≤850kg/m³), easy to cut, ideal for indoor ceiling and wall decorations.

Perforation specification:

Aperture: φ2mm~φ15mm (conventional φ3mm/φ5mm/φ8mm)

Hole type: round hole, square hole, strip hole, art pattern customization

Perforation rate: 5%~30% (acoustic optimization recommends 8%~15%)

Applicable scenarios: office, conference room, hotel lobby, commercial space

2. Calcium silicate perforated board

Key Advantages: Fire-resistant and moisture-proof (Class A1 non-combustible, water absorption rate ≤8%), strong weather resistance, suitable for both indoor and outdoor use.

Perforation specification:

Thickness: 6mm~20mm (commonly used 8mm/12mm)

Surface treatment: clear water, spraying, wood grain, imitation stone grain

Special function: can be combined with sound-absorbing cotton to improve noise reduction performance

Application Scenario: Subway stations, hospitals, school exterior walls, industrial plants

3. Fiber cement pressure perforated plate

Key Advantages: Ultra-high strength (flexural strength ≥18MPa), corrosion resistance, suitable for extreme environments.

Perforation specifications:

Sheet thickness: 4mm~12mm (outdoor recommended ≥8mm)

Weather resistance: Stable and no deformation at -40℃~80℃

Customization: support for irregular punching and gradient perforation design

Application scenarios: building facades, tunnel decoration, outdoor sunshade systems

II. Technological breakthrough: make the perforated board more than "good-looking"

✅ Precision punching technology

Utilizing a CNC hydraulic punch, the precision of hole placement is maintained at ±0.1mm, with edges free of burrs, ensuring consistent visual appearance.

Support customization of gradient perforation (such as from dense to sparse) and artistic patterns (LOGO, geometric shapes).

✅ Acoustic optimization design

Combined with sound-absorbing cotton (rock wool/polyester fiber) as a backing, the NRC (noise reduction coefficient) can reach 0.6~0.9, creating a quiet space.

Case: A concert hall adopts φ5mm round holes with a 15% perforation rate, reducing the reverberation time by 30%.

✅ Structural reinforcement process

The fiber cement board utilizes a reinforced fiber mesh, ensuring high strength even with a high perforation rate (25%+), and a wind pressure resistance of ≥2.5kPa.
