Anping Xinye Metal Wire Mesh Products Co., Ltd. is a dedicated manufacturer based in Hengshui, Hebei, China, specialized in producing high-quality metal mesh and perforated sheet products. Our 304 stainless steel perforated metal sheet with a 3 mm hole diameter is engineered for demanding applications where reliability and longevity matter. Every sheet can be supplied with custom fabrication, a one-year warranty, and a mill test report to ensure material traceability and performance confidence. With a factory area of 5,000 to 10,000 square meters and a skilled team of 51-100 employees, we are fully equipped to serve global clients with consistent quality and efficient production.
This perforated sheet is produced from selected 304 stainless steel coils and strips. The material contains chromium and nickel, which provide a protective oxide layer and help resist rust, pitting, and chemical attack in many environments. Perforation is performed with high-precision tooling to create clean, uniform round holes of 3 mm diameter across the sheet surface. The combination of stainless steel durability and open-pattern construction results in a product that is lightweight yet strong, easy to handle, and effective for numerous mechanical, architectural, and hygienic applications.
Key Features and Benefits
- Material Integrity: Made from 304 stainless steel, the sheet offers excellent corrosion resistance, oxidation resistance, and weldability in outdoor and industrial environments.
- Precision Perforation: The 3 mm round holes are produced with controlled tolerance and consistent spacing to ensure uniform open area and reliable performance.
- Strength and Durability: Stainless steel retains its structural integrity even under high-moisture or chemical-exposed conditions, reducing maintenance costs and extending service life.
- Custom Fabrication: Sheets can be cut, sheared, bent, or formed according to your drawings. Different hole patterns, sheet dimensions, and edge finishes are available on request.
- Traceability and Assurance: A mill test report accompanies every order to verify the chemical and mechanical properties of the 304 stainless steel material. A one-year warranty provides additional peace of mind.
- Versatile Applications: Common uses include filtering, screening, ventilation grilles, architectural accents, machinery guarding, acoustic panels, and separation in food processing or chemical industries.
Detailed Product Overview
Our perforated metal sheet starts as premium 304 stainless steel strip or coil. The sheet is then processed on high-tonnage punching machines to generate consistent round holes with minimal burrs. Deburring and edge finishing can be added if your application requires smooth contact surfaces. The resulting construction permits air, light, liquid, and sound to pass through while maintaining a strong barrier against larger particles or impact. Because 304 stainless steel is widely recognized for its balance of strength, formability, and corrosion resistance, it is a common choice for durable enclosures, filters, and decorative panels. This product offers excellent compatibility with welding, bending, and shearing, so fabricators can integrate it easily into larger assemblies.
Dimensions and Customization Options
We offer flexible dimensions to maximize your project efficiency. The standard width and length can be fabricated according to your specifications. For large production runs, we can also produce blanks that are ready for downstream processing. The actual hole tolerance and pitch tolerance follow common industry practices, and final dimensions are verified with calibrated measuring instruments. If your application requires tight tolerances or unusual hole patterns, please share your drawings—our team can evaluate the feasibility and provide recommendations without extra obligation. Custom fabrication includes cutting to size, edge flattening, drilling, bending, rolling, and assembling with other metal components. These services help you save time and reduce fabrication waste on site.

Quality Control and Documentation
Quality is embedded in every stage of production. From careful selection of raw material to rigorous final checking, our team ensures that each sheet meets your expectations. The 304 stainless steel mill test report states the material grade, chemical composition, and mechanical properties, giving you the data needed for engineering and compliance reviews. Any custom fabrication is also inspected for dimensional accuracy and edge quality before packing. We offer a one-year warranty covering manufacturing defects, and our sales engineers are ready to help you select the right specification. For special documentation or additional inspection requirements, please inform us before production; our factory will arrange suitable arrangements based on your needs.

Frequently Asked Questions
1. What thickness of 304 stainless steel perforated sheet do you offer?
We can provide various thicknesses based on the load-bearing and flatness requirements of your application. Please tell us the sheet thickness you need or describe your project, and we will recommend a suitable option. Custom thicknesses can also be discussed.
2. Can you produce custom hole patterns and sizes?
Yes. Custom fabrication is one of our core strengths. In addition to the standard 3 mm round holes, we can produce different hole sizes, shapes, and patterns according to your drawings. Please send us your specifications so we can review the tooling and production process.
3. What is a mill test report and can I get one with my order?
A mill test report is a manufacturer's document that verifies the chemical composition and mechanical properties of the stainless steel material. Yes, a mill test report is included with this product to help you confirm that the raw material meets your material requirements.
4. How long does delivery take?
Delivery time depends on the order quantity and the complexity of custom fabrication. For standard sheets, production may be completed quickly, while customized items may require additional time. We will confirm the schedule in writing before you place the order.
5. Which ports are used for shipment?

7. Are these sheets suitable for outdoor use?
304 stainless steel has good corrosion resistance and is commonly used in outdoor applications such as architectural panels, ventilation covers, and machinery guards. However, for very aggressive environments such as heavy salt spray or strong chemical exposure, we recommend discussing alternatives with our engineers.
8. Can I get a sample before placing a bulk order?
Yes, samples are available upon request. We can produce small sample pieces matching your proposed specification so you can evaluate the quality, appearance, and dimensional accuracy. Samples may be shipped by air, and the related sample cost can be offset by future orders.
