Anping County Boli Hardware Wiremesh Products Factory presents our 0.15mm Thin Photo-etched Speaker Mesh, precision-crafted from premium 316L Stainless Steel with 0.4mm square holes. As a dedicated manufacturer since 1998, we combine decades of metalworking expertise with advanced photo-etching technology to deliver a mesh that balances exceptional thinness, durability, and acoustic transparency. This speaker mesh is designed to protect sensitive components while allowing optimal sound passage, making it a reliable choice for high-end audio devices, automotive speakers, and industrial acoustic applications.
Key Features & Benefits
- Ultra-thin 0.15mm Thickness: Minimizes obstruction to sound waves, ensuring clear and natural audio output. The thin profile also allows for easy integration into compact speaker designs.
- Premium 316L Stainless Steel: Offers superior corrosion resistance, even in humid or marine environments. Ideal for long-term use in car audio, outdoor speakers, and medical devices where hygiene and durability are critical.
- Precise 0.4mm Square Holes: The photo-etching process guarantees uniform hole size and shape, with no burrs or deformation. This consistency ensures reliable acoustic performance and protects against dust and debris.
- Photo-etching Manufacturing: A subtractive process that produces intricate patterns with high accuracy, free from heat-affected zones. This method is ideal for large-scale production without compromising quality.
- Customizable Dimensions: Available in rolls or cut-to-size sheets. We can adjust hole size, pattern density, and overall dimensions to meet your specific design requirements.
- Excellent Strength-to-Weight Ratio: Despite its thinness, 316L stainless steel provides robust mechanical strength, resisting deformation during handling and installation.

Detailed Product Description
Our photo-etched speaker mesh is engineered for applications where both acoustic transparency and physical protection are paramount. The 0.15mm thickness is exceptionally thin, reducing sound absorption and diffraction to a minimum. Unlike woven meshes that can have inconsistent openings, the photo-etching process creates perfectly square holes with sharp edges, ensuring that each hole delivers the same resistance to airflow. This uniformity is critical for high-fidelity speaker systems, where even minor variations can affect frequency response.
The choice of 316L stainless steel is deliberate: it contains molybdenum, which enhances resistance to pitting and crevice corrosion in chloride environments. This makes the mesh suitable for marine speakers, outdoor audio equipment, and even medical devices like hearing aids or surgical instruments where sterilization is required. The material is also non-magnetic, which prevents interference with sensitive electronics.
The 0.4mm square hole size strikes a balance between particle exclusion and sound permeability. It blocks dust, lint, and small insects while allowing high-frequency sound waves to pass with minimal attenuation. For customers needing different acoustic properties, we can adjust the hole size and pitch within a wide range—simply contact our technical team to discuss your requirements.

Frequently Asked Questions (FAQ)
-
Q: What is the open area percentage of this mesh?
A: The open area ratio is approximately 44% for a standard square pattern with 0.4mm holes and a pitch of 0.6mm. If you need a different open area, we can adjust the hole size and spacing accordingly. -
Q: Can this mesh be used for outdoor speakers?
A: Yes, the 316L stainless steel provides excellent corrosion resistance, making it suitable for outdoor, marine, and high-humidity environments. The thin profile also helps resist wind loading. -
Q: What is the minimum order quantity?
A: For standard sizes, the MOQ is 100 square meters. For custom sizes or patterns, the MOQ may vary depending on complexity. We recommend contacting us for a precise quote. -
Q: How long does production take?
A: Typical lead time is 15–20 working days after order confirmation. For urgent orders, we can discuss expedited production at an additional cost. -
Q: Do you provide free samples?
A: Yes, we offer free samples (A4 size or smaller) for evaluation, but the customer is responsible for shipping costs. Samples are typically sent within 3–5 working days. -
Q: Can you cut the mesh into specific shapes (e.g., circles or custom outlines)?
A: Absolutely. We can die-cut, laser-cut, or stamp the mesh into custom shapes to fit your speaker housing. Please provide a drawing or CAD file for quotation. -
Q: Is this mesh suitable for high-frequency tweeters?
A: Yes, the very thin material (0.15mm) and precise square holes minimize acoustic resistance, making it well-suited for high-frequency drivers. Many customers use it for tweeters and mid-range speakers. -
Q: What certifications do you have for this product?
A: Our factory operates under strict quality management systems. We can provide material test certificates (MTC) for 316L stainless steel upon request. Specific product certifications are available depending on your industry requirements—please inquire for details.
