Speaker Grille Metal Mesh Sheet in 304 Stainless Steel (AISI 304 (1.4301)) is used for cutting custom speaker grilles from flat perforated metal sheet for cabinets, car-audio enclosures, PA boxes and electronics prototypes. The alloy gives good general corrosion resistance in atmosphere and fresh water and is essentially non-magnetic (annealed), with a practical service limit of approx. +450 °C continuous.

Where 304 Stainless Steel Speaker Grille Metal Mesh Sheet Is Used
- DIY & custom loudspeaker builders: cabinet grilles cut to any shape.
- Car audio installers: subwoofer box and custom panel grilles.
- Pro audio & PA: full-face cabinet fronts.
- Electronics prototyping: enclosure grilles before tooling is made.
Ordering Speaker Grille Metal Mesh Sheet in 304 Stainless Steel
- Hole & pitch: Larger holes (2–3 mm) for woofers, fine holes (1 mm) for full-range and tweeters.
- Thickness: 0.6–1.0 mm; thicker sheet rings less and protects better.
- Open area: Aim for 30–40 % so the grille is acoustically transparent.
Mistakes to Avoid with Speaker Grille Metal Mesh Sheet
- Choosing a sheet under 25 % open area, which muffles the speaker.
- Using thin sheet over large woofers, which buzzes at high output.
