As a professional manufacturer with over 25 years of experience in the wire mesh industry, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Etched Metal Dustproof Grille designed specifically for Bluetooth speakers. This grille features a precise 1.2mm hole diameter and an impressive 80% open area, ensuring optimal sound transmission while providing reliable dust protection. Our factory, established in 1998, has exported millions of dollars worth of high-quality metal mesh products to markets worldwide, including North America, Europe, and Southeast Asia, making us a trusted partner for OEM and ODM projects.
The etched metal grille is manufactured using advanced etching technology, which creates clean, burr-free holes with consistent spacing. The 1.2mm hole diameter strikes the perfect balance between acoustic transparency and effective dust blockage, while the 80% open area maximizes sound output without compromising structural integrity. The anti-rust property ensures long-lasting performance even in humid environments, making it ideal for portable Bluetooth speakers used outdoors.

Key Features & Benefits:
- Superior Sound Transmission: The 80% open area allows sound waves to pass through with minimal obstruction, delivering clear and rich audio quality.
- Effective Dust Protection: The 1.2mm hole diameter prevents dust and debris from entering the speaker enclosure, extending the life of internal components.
- Anti-Rust Performance: Our grille is treated with an anti-rust coating or made from stainless steel, ensuring corrosion resistance in humid or outdoor environments.
- Precision Etching: The chemical etching process produces smooth edges and uniform hole patterns, eliminating sharp burrs that could damage speaker membranes.
- Customizable Design: We offer custom sizes, shapes, thicknesses, and surface finishes to match your specific speaker design requirements.
- Durable Construction: Made from high-quality metal, the grille can withstand daily wear and tear, maintaining its appearance and function over time.
- Easy Integration: The flat panel design can be easily mounted using adhesive, screws, or press-fit, simplifying your assembly process.
Our etched metal grille is an ideal choice for manufacturers seeking a reliable, high-performance dustproof solution for Bluetooth speakers. The combination of large open area and small hole diameter ensures both acoustic excellence and protection. Additionally, the anti-rust property makes it suitable for marine, garden, and portable speaker applications where moisture is a concern.
Technical Advantages:
- Consistent Hole Spacing: Etching technology guarantees precise pitch and hole alignment, ensuring uniform acoustic performance across the entire panel.
- No Deformation: Unlike punching, etching does not cause material deformation, preserving the flatness and structural integrity of the grille.
- Thin Material Capability: We can etch grilles as thin as 0.3 mm, ideal for lightweight speaker designs.
- High Volume Production: Our factory has the capacity to produce large quantities with consistent quality, meeting tight deadlines.
