Stainless Steel Audio Speaker Grille Panels with Protective Film: Durable Solutions for Subway and Airport Hubs

Introduction: Protecting Performance in High-Traffic Spaces

In today’s fast-paced transportation hubs, every detail—from signage to acoustic panels—must combine resilience with performance. The deployment of CNC processed stainless steel audio speaker grille panels with protective film in the Guangzhou Metro Line 18 and the city’s new airport terminal sets a new standard for both durability and sound quality in public infrastructure.

Case Study: Guangzhou Metro & Airport Terminal

Project Challenge

Metro and airport environments face:
