Stainless Steel Etching SUS304 SUS316 Speaker Grill Meshes with Flexible Holes Shape for Car

Our stainless steel etched speaker grill meshes are custom manufactured for car audio systems, door panels, dashboard speakers, and aftermarket upgrades. Using precision chemical etching, we produce SUS304 and SUS316 stainless steel grilles with flexible hole shapes, clean edges, and consistent patterns — ideal for both acoustic performance and premium automotive interior design.

Etching Process

Chemical etching is the core of our production. Unlike stamping or laser cutting, chemical etching does not create burrs, stress, or deformation on the metal surface. This makes it especially suitable for thin stainless steel speaker grilles that require fine details, high open area, and smooth edges.

We offer both full etching and half etching:

• Full Etching – holes are etched completely through the stainless steel sheet to create open mesh patterns for sound transmission.
• Half Etching – partial depth etching for recessed logos, stepped edges, branding, or decorative details without cutting through the material.

Both SUS304 and SUS316 are suitable for etching. SUS304 offers excellent corrosion resistance and cost efficiency for most automotive interior applications, while SUS316 provides higher resistance to moisture, salt, and harsh environments, making it ideal for premium or exterior-adjacent speaker grilles.

Flexible Hole Shape Options

One of the biggest advantages of chemical etching is design freedom. We can produce almost any hole shape without additional tooling costs:

• Round holes
• Square holes
• Hexagonal holes
• Oval and elongated holes
• Slot patterns
• Diamond and custom geometric shapes
• Logo-shaped and brand-specific perforations
• Gradual or mixed hole patterns for acoustic tuning

Hole size, spacing, density, and arrangement can all be customized based on your acoustic requirements and visual design. This flexibility allows you to control sound transparency, airflow, and appearance without being limited by traditional punching tools.

Manufacturing Capabilities

Whether you need a small batch for sampling or large-volume production for automotive projects, we maintain stable quality and consistent etching results.

Surface Treatment Options

To match different automotive interior styles and durability requirements, we offer multiple surface finishes:

• Gloss Finish – smooth and reflective, suitable for premium decorative grilles
• Matt Finish – low reflection and fingerprint resistant, ideal for modern interiors
• Brushed Finish – directional metallic texture with scratch resistance
• Anodizing – for color options and enhanced corrosion protection
• Powder Coating – durable colored finish for specific design needs
• Electroplating / PVD Coating – for premium metallic colors and wear resistance
• Passivation – improves corrosion resistance of stainless steel after etching

Each finish can be applied to SUS304 or SUS316 grilles depending on your target appearance and environment.
