Anti-Oxidation Coating Audio Speaker Grille Panels | Coastal Airport Acoustic Solution

This article details how CNC processed stainless steel audio speaker grille panels with anti-oxidation coating provide long-lasting durability and premium audio at Xiamen International Airport. The advanced coating ensures no rust or fading, even in harsh coastal climates, with third-party testing and industry references backing the results.

Anti-Oxidation Coating Stainless Steel Audio Speaker Grille Panels: Long-Lasting Sound for Coastal Airports

Introduction: Defending Performance in Challenging Environments

Salt air, humidity, and constant traffic challenge building materials at every coastal airport. CNC processed stainless steel audio speaker grille panels with anti-oxidation coating are engineered to provide flawless acoustic performance and a pristine finish—year after year. At the Xiamen International Airport, this advanced technology is setting the standard for reliability and style in aviation facilities.

Case Study: Xiamen International Airport

Project Overview

Passenger terminals, boarding areas, and concourses exposed to high humidity and sea salt.
Need for clear, reliable PA system audio and emergency announcements.
Desire for panels that retain “like new” appearance without frequent maintenance or replacement.

Jintong’s Solution

CNC processed audio speaker grille panels treated with a proprietary anti-oxidation coating—lab-proven to resist salt spray, corrosion, and staining even in marine climates.
Custom micro-perforated patterns for maximum sound clarity and transparency.
All panels color-matched to the airport’s design scheme and installed with tamper-proof fasteners for security.
Supported by third-party testing from the National Engineering Laboratory for Corrosion Control and International Institute of Acoustics and Vibration.

Industry Reference: Dezeen Airport Design and ArchDaily Transportation Hubs highlight the use of anti-corrosion coatings for durability in coastal and high-traffic sites.

Project Results

After 18 months in operation, no visible rust, dulling, or coating degradation—even near open air jet bridges.
Facility maintenance reduced: only periodic dusting required, no acid washing or repainting.
PA clarity rated “excellent” in both passenger and staff satisfaction surveys.

FAQ: Anti-Oxidation Coating Speaker Grilles

Q: How is anti-oxidation performance tested?
A: Panels undergo ASTM B117 salt spray testing and accelerated weathering in certified labs.

Q: Will the coating peel or bubble in harsh weather?
A: No, coatings are applied using advanced powder or nano-ceramic methods and guaranteed for years of adhesion.

Q: Are coated grilles available in custom colors?
A: Yes, color options include RAL, metallic, and custom blends.
