Micro Perforated Metal Sheet — Precision, Strength, Acoustic Performance

Micro Perforated Metal Sheet

Introduction
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.

Why choose our micro perforated metal sheet?

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.

Applications — where micro perforated sheets excel

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.

Manufacturing methods we use

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

Ordering, samples and delivery

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.

How to specify your sheet — quick checklist

Material (e.g., 304 stainless steel)
Thickness (mm)
Hole diameter (mm) and pattern (round/square/slot)
Pitch and layout (staggered or straight)

Microporous perforated metal sheet

Comparing a micro perforated metal sheet to regular perforated sheets

A micro perforated metal sheet differs mainly in hole size and acoustic behavior. Regular perforated sheets may have larger holes and a bolder visual texture. Choosing a micro perforated panel gives you an elegant finish and finer acoustic control, ideal where both performance and aesthetics matter.

Case example: acoustic ceiling retrofit

We supplied micro perforated metal sheet panels for an open-plan office retrofit where the client wanted minimal visual impact and improved speech privacy. Using 0.8 mm micro perforated metal sheet panels backed with porous absorber, measured noise levels dropped noticeably and occupants reported better speech privacy without losing the modern metallic look.

Surface treatments & finishing guidance

To extend life and match design intent, specify a finish when ordering a micro perforated metal sheet. Powder coating is common for colored architectural panels; polished stainless steel works well for interior accents. For coastal environments, choose 316 stainless steel with passivation. If paint adhesion is needed, request pre-treatment in your RFQ.

Quality control and inspection

Every micro perforated metal sheet we ship undergoes visual inspection and dimensional checks. We test hole diameter, pattern uniformity, flatness and edge condition. Measurement reports are available for critical projects. These quality checks reduce surprises at installation.

Logistics and export support

We pack sheets with protective film and plywood crating for export. Large orders are palletized and secured to minimize movement. We offer EXW or FOB shipping terms; tell us your preferred port and we will prepare export documentation. For urgent prototype runs, express air freight is possible.

Practical tips for designers & buyers

Acoustic design: Pair the micro perforated metal sheet with porous backing and a specified air gap; mock-up testing is recommended before large production runs.
Handling & installation: For large spans, provide support framing to avoid sagging; thin panels need careful handling.
Corrosion resistance: Use 316 stainless steel or protective finishes for coastal projects.
Cleaning: Avoid abrasive brushes on polished finishes; use mild detergents.

After perforation, especially for plates with very dense hole patterns, the perforated metal sheets will experience significant deformation. We perform flattening treatment after completing all perforation processes. Below is the video of flattening perforated metal sheets:

After the leveling process, our perforated metal sheets can be precisely laser-cut into any custom shape as required. Below is a production video demonstrating the laser-cutting process:
