SenChi - Micro Perforated Metal Sheets
A micro perforated metal sheet is a versatile, high-precision material used where strength, airflow, and acoustic performance must meet tight tolerances. At Anping Senchi Metal Wire Mesh Products Co., Ltd, we manufacture micro perforated metal sheets with hole diameters starting from 0.2 mm and up. Our factory in Anping, Hebei, China, offers punching, laser cutting, chemical etching, and a full range of finishing options so you can get the exact panel you need.
Most popular related searches
- Practical benefits — Micro perforated panels deliver controlled porosity while keeping structural integrity. Compared with larger perforations, micro holes provide smoother acoustic absorption and a finer visual finish for decorative facades and interior elements.
- Manufacturing accuracy — We control hole diameter, pitch, and edge quality to maintain consistent performance across batches. Consistency reduces waste and simplifies installation on site.
- Material variety — We produce micro perforated metal sheet in 304 and 316 stainless steel, aluminum, and galvanized steel, with brass or copper available on request.
- Finishes & post-processing — Deburring, polishing, passivation, powder coating, and plating are available to meet aesthetic and corrosion-resistance requirements.
- Hole diameter: 0.2–3.0 mm (typical for micro perforation)
- Thickness range: 0.1–3 mm
- Materials: 304/316 stainless steel, aluminum, galvanized steel (brass/copper optional)
- Standard sheet sizes: 1000*2000?1220*2440?1250*2500
- Patterns: round, square, slot, staggered
- Tolerances: hole diameter ±0.05 mm (process dependent)
- Surface treatments: deburring, polishing, passivation, powder coat, plating
- Acoustic panels and ceilings — A micro perforated metal sheet combined with a porous absorber and a specified air gap offers predictable sound absorption across mid and high frequencies.
- Ventilation and filtration — Small, precise holes control airflow while keeping out debris.
- Decorative facades and interior design — Micro perforation creates a refined texture for cladding, balustrades, and feature walls.
- Lighting diffusers & speaker grilles — Even light distribution and a professional visual finish.
- Industrial shielding & safety guards — Preserve strength while minimizing weight.
- CNC Punching: Efficient for many patterns; ideal where hole size and spacing allow mechanical punching.
- Laser Cutting: Flexible for custom shapes and low-volume runs.
- Chemical Etching: Best for the smallest hole diameters and ultra-fine patterns where punch tooling is impractical.
- Quality control: We inspect hole diameter, pitch, burr level and flatness before shipping
- MOQ: None — we accept single-piece orders for prototyping and small projects.
- Samples: Cut samples available on request.
- Lead time: Typical production lead time is 2–4 weeks depending on quantity and finish.
- Packaging: Sheets are wrapped and secured for export; we ship via sea or air under EXW/FOB/CIF terms on request.
- Quality documents: Material certificates included; third-party testing supported on request.
