Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998 with over two decades of expertise in wire mesh solutions. Our 304 Stainless Steel Wire Mesh Filter Strainer (0.5 mm opening, 4 inch diameter) is specifically engineered for demanding chemical processing environments where corrosion resistance, high temperature stability, and precise filtration are critical. With an annual export value of US$5–10 million and shipments to major global markets, we deliver industrial-grade reliability that meets rigorous international standards.
This filter strainer combines premium 304 stainless steel with a 0.5 mm square opening, providing an effective barrier against particles while maintaining excellent flow rates. The 4-inch diameter fits standard pipeline systems and is available in custom configurations. Rated for continuous operation up to 200°C, it performs flawlessly in hot chemical filtration, oil refining, water treatment, and food processing applications. Each unit is manufactured with precision weaving to ensure consistent mesh geometry and long service life.
Key Features & Technical Specifications
- Corrosion Resistance: 304 stainless steel offers excellent resistance to acids, alkalis, and organic solvents, making it ideal for chemical processing.
- High Temperature Tolerance: Operates reliably at up to 200°C without deformation or loss of filtration efficiency.
- Precise Opening Size: 0.5 mm (500 micron) square openings effectively trap medium-sized particles while allowing smooth fluid flow.
- Standard 4-Inch Diameter: Compatible with 4-inch flanges, pipes, or custom housings; easily integrated into existing systems.
- Durable Construction: Wire diameter and weave pattern are optimized for mechanical strength and minimal clogging.
- Customizable Options: Available in different mesh counts, wire diameters, edge finishes (welded, folded, or with gasket), and additional reinforcement rings.

Frequently Asked Questions (FAQ)
Q: Can this strainer be used for food-grade applications?
A: Yes, 304 stainless steel is food-safe and widely used in food & beverage filtration. Please confirm the specific food contact regulations with your local authority.Q: What is the maximum pressure rating?
A: The pressure rating depends on the wire diameter and edge finish. For standard 0.28 mm wire, typical operating pressure is up to 5 bar (73 psi). For higher pressures, we can reinforce the edge or use a thicker wire.Q: Is the 0.5 mm opening the exact micron size?
A: The nominal opening is 0.5 mm (500 microns). Actual measurement may vary within ±0.05 mm due to weaving tolerance. If you need tighter tolerance, please specify upon order.Q: Can I order a non-standard diameter or custom shape?
A: Absolutely. We offer custom sizes, shapes (rectangular, oval, etc.), and edge finishes. Minimum order quantity may apply for custom items.Q: How do I clean the strainer?
A: It can be cleaned by backwashing with water or air, ultrasonic cleaning, or soaking in a mild acid solution. Avoid abrasive cleaning that may damage the woven mesh.Q: What packaging is used for export?
A: Each strainer is individually wrapped in protective material, then packed in sturdy cartons or plywood crates to prevent deformation during shipping. We ship via Tianjin, Qingdao, Shanghai, or Foshan ports.Q: Do you provide samples?
A: Yes, stock samples are available for quality evaluation. Custom samples can be produced with a lead time of 5–10 working days. Shipping cost is negotiable.Q: Can this strainer withstand aggressive chemicals like sulfuric acid?
A: 304 stainless steel has good resistance to many organic and inorganic acids at moderate concentrations and temperatures. For highly corrosive media such as concentrated sulfuric acid, we recommend 316L or other alloys. Please consult our technical team for specific chemical compatibility.
