Custom OEM Thin 0.3mm SUS304 Round Etched Vent Mesh Honeycomb Speaker Grill Chemical Etching Metal Filter Grille

Our round etched ventilation mesh is precision fabricated from ultra-thin 304 stainless steel strip via professional chemical etching technology. As a reliable custom manufacturer, we deliver one-stop OEM custom service for all sizes and patterns of etched stainless steel vent mesh.

The production flow starts with flattening and cutting stainless steel coils into thin sheets, followed by photoresist coating, film exposure and developing to transfer honeycomb patterns. Chemical etching precisely cuts uniform hexagonal honeycomb holes and peripheral mounting holes without mechanical deformation. After stripping, cleaning and passivation anti-rust treatment, each thin 304 stainless steel filter screen goes through leveling and micro deburring to eliminate sharp edges.

No electroplating or paint coating is applied; the surface retains natural bright polished stainless steel texture with stable anti-corrosion performance. This chemical etching metal grille serves perfectly as honeycomb metal speaker grill, equipment ventilation filter and dust-proof mesh, holding ultra-tight dimensional tolerances for precise assembly of electronic, audio and automation devices.
