Powder-Coated Perforated Metal Panels: The Durable Solution for Long-Term Sound Control

Why Durability and Acoustics Must Coexist

In modern high-traffic environments—airports, transportation hubs, manufacturing corridors, schools—traditional acoustic materials degrade quickly under stress. Powder-coated perforated metal panels provide the perfect balance between sound absorption, durability, and aesthetics. These panels offer the performance of metal with a soft-touch finish and outstanding resistance to impact, corrosion, and cleaning agents.

Engineered for indoor and semi-exterior use, they meet and exceed global standards like ASTM E84 and ISO 11654 while offering an NRC of up to 0.90. See real implementation examples in our case portfolio.

Panel Construction and Material Advantages

• Substrate: Aluminum or galvanized steel (0.8mm–1.2mm)

• Coating: Polyester powder or PVDF powder coat with 60–80μm thickness

• Perforation Pattern: CNC controlled round, slot, or custom laser-cut motifs

• Backing: PET, mineral wool, or glass fiber acoustic infill

• Mounting: Hidden frame, screw-fixed system, or magnetic clip

Functional Use Cases

• Transit center ceilings and walls

• Heavy-use public washrooms and corridors

• School gymnasiums and auditoriums

• Medical research labs and sterile environments

• Retail and warehouse interiors

These panels can be color-matched to brand palettes and paired with anti-slip perforated flooring for unified space acoustics.

Case Study: MetroRail Terminal Retrofit, São Paulo

The São Paulo MetroRail authority commissioned a retrofit of their Line 3 terminals. The old drywall-based acoustic system was vandalized and crumbling. Powder-coated perforated metal panels were used to re-clad walls and partial ceilings across 6,000 sqm. Results included:

• Vandal-resistance improved to zero paint damage after 6 months

• Average noise level reduced by 9.8 dB

• Cleaning time per 100 sqm reduced by 35%

Project insights were later covered in Architectural Digest and Acoustical Society of America papers.
