Shower Head Face Plate (Etched / Micro-Perforated) in 304 Stainless Steel (AISI 304 (1.4301)) is used for forming the spray face of hand, overhead and rain shower heads, where nozzle size and ring pattern set the spray feel and flow. 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 Shower Head Face Plate (Etched / Micro-Perforated) Is Used
- Shower head OEMs: stainless face plates replacing molded plastic nozzles on premium heads.
- Hotel & spa fit-outs: large 200–250 mm rain heads specified for guest bathrooms.
- Water-saving programs: low-flow plates certified for 7.5–9.5 L/min.
- Misting & cooling: atomizing plates for patio and greenhouse mist heads.
Ordering Shower Head Face Plate (Etched / Micro-Perforated) in 304 Stainless Steel
- Nozzle hole & count: Hole diameter and count set the flow at a given pressure — specify the target L/min at 3 bar, not only the hole size.
- Etched or punched: Photo-etched plates give tapered, burr-free nozzles below 0.5 mm; punching suits larger holes.
- Thickness & finish: 0.6–1.0 mm in SS304 or SS316, brushed, polished or PVD-coated to match the trim.
Mistakes to Avoid with Shower Head Face Plate (Etched / Micro-Perforated)
- Matching hole count to a competitor but not the plate thickness, which changes the flow rate.
- Specifying 0.15 mm mist holes in a hard-water region without an inlet filter — they scale shut within weeks.
