Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5-10 Million. Our 316L Multilayer Sintered Wire Mesh with 20 micron pore size, 1.2mm thickness, and 900°C heat resistance delivers exceptional filtration performance in extreme environments. Engineered for durability and precision, this sintered mesh combines high strength, thermal stability, and corrosion resistance, making it an ideal choice for demanding industrial applications.
Our product is produced using advanced sintering technology that bonds multiple layers of 316L stainless steel wire mesh without any adhesives, creating a uniform porous structure. The 20 micron pore size ensures fine particle retention, while the 1.2mm thickness provides robust mechanical integrity. Withstanding continuous temperatures up to 900°C, this mesh is suitable for high-temperature filtration, catalytic support, and fluidization processes.
Below are key features and technical specifications that set our product apart:
- Material: Premium 316L stainless steel – excellent corrosion resistance in acidic and chloride environments.
- Pore Size: 20 micron (nominal) – consistent and uniform filtration performance.
- Thickness: 1.2mm ±0.1mm – balanced strength and flow efficiency.
- Heat Resistance: Up to 900°C in oxidizing atmospheres – maintains structural integrity at high temperatures.
- Multilayer Structure: Typically 3–5 layers (customizable) – prevents particle migration and enhances mechanical strength.
- Sintering Process: Diffusion bonding at high temperature – creates a monolithic, non-delaminating sheet.
- Surface Finish: Cleaned and degreased – ready for direct installation.
- Customization: Available in different sizes, shapes (discs, sheets, rolls), and additional layers upon request.

Advantages for Your Applications:
- High Temperature Filtration: Ideal for flue gas treatment, catalyst recovery, and thermal processing where conventional meshes fail.
- Chemical Compatibility: 316L resists pitting and crevice corrosion in chlorides, making it suitable for marine and chemical environments.
- Mechanical Stability: The multilayer sintered structure eliminates mesh shifting, providing consistent filtration over long service life.
- Easy Cleaning and Regeneration: The metal filter can be backwashed, ultrasonically cleaned, or thermally regenerated, reducing replacement costs.
- Custom Shapes: We can cut, roll, or form the mesh into discs, cylinders, or custom shapes for your specific equipment.

Frequently Asked Questions
Q1: What is the difference between 316L and 304 sintered mesh for high-temperature use?
A: 316L contains molybdenum, which provides superior resistance to chlorides and higher creep strength at elevated temperatures. For continuous operation above 800°C, 316L is recommended over 304 to avoid oxidation and scaling.
Q2: Can the pore size be customized to other micron ratings?
A: Yes, we offer a range of pore sizes from 5 micron to 500 micron. The 20 micron specification is standard, but we can adjust the wire diameter and layer configuration to achieve different filtration ratings. Please contact us with your requirements.
Q3: How does the sintering process affect the mesh's strength compared to woven mesh?
A: Sintering diffusion bonds the wire intersections, eliminating relative movement. This results in a rigid, monolithic structure with higher tensile and burst strength compared to standard woven mesh, especially under high pressure differentials.
Q4: What is the maximum pressure drop this mesh can handle?
A: The pressure drop depends on fluid viscosity, flow rate, and pore size. For a 20 micron mesh with 1.2mm thickness, typical differential pressure limits are 2-5 bar, but we recommend consulting our engineering team for specific process conditions.
Q5: Is this product suitable for food and pharmaceutical applications?
A: Yes, 316L stainless steel is food-grade and meets FDA standards for contact with food. Our mesh is manufactured in a clean environment and can be supplied with certifications upon request. However, we recommend verifying specific compliance with local regulations.
Q6: How long does the mesh last at 900°C continuous operation?
A: Service life depends on factors such as thermal cycling, atmosphere, and mechanical load. In a clean oxidizing environment, the mesh can last several thousand hours. For extended life, we recommend using a protective coating or reducing the temperature to 800°C. We can provide accelerated test data on request.
Q7: Do you offer samples before bulk order?
A: Absolutely. We can provide free samples (A4 size or smaller) with freight collect. For larger custom samples, please contact our sales team to discuss terms.
Q8: What are the available packaging and shipping options?
A: Standard packaging includes plywood cases or pallets with protective wrapping. We ship via sea, air, or express (DHL, FedEx) from Tianjin, Qingdao, Shanghai, or Foshan. Lead time for standard sheets is 15-20 days after order confirmation.
