High-Performance Wire Mesh Filter Screen for Industrial Filtration
Product Overview
Our premium wire mesh filter screen is engineered for demanding industrial filtration applications. Manufactured from high-grade stainless steel (304, 316L, 904L) or specialized alloys (Hastelloy, Monel), these screens provide precise particle separation from 1 micron to 10,000 microns. The woven wire mesh construction offers a unique combination of high flow rates, mechanical strength, and thermal resistance, making it the preferred choice for liquid filtration, gas filtration, and solid-liquid separation across multiple industries.
Each wire mesh filter screen is produced using advanced Dutch weave, plain weave, or twilled weave patterns, ensuring consistent aperture size and uniform filtration performance. Available in roll form, cut-to-size sheets, or custom-fabricated filter discs and cylinders, our products meet the exacting standards of B2B procurement requirements.
Key Features
- Precision Filtration: Mesh ratings from 2 mesh to 635 mesh with ±2% aperture tolerance ensure reliable particle retention.
- High Mechanical Strength: Crimped wire construction provides superior burst pressure resistance up to 50 bar (725 psi) for high-pressure filtration systems.
- Corrosion & Heat Resistance: Suitable for operating temperatures from -200°C to 800°C, with excellent resistance to acidic, alkaline, and organic solvents.
- Easy Cleaning & Reusability: Backwashable design allows for repeated cleaning cycles (ultrasonic, chemical, or mechanical), reducing replacement costs by up to 60%.
- Customizable Configurations: Available with edge welding, spot welding, or epoxy bonding for frames, plus optional gaskets and sealing rings.
- Low Pressure Drop: Optimized open area ratio (30%–55%) minimizes energy consumption in pumping systems.

Application Scenarios
Petrochemical & Oil Refining
Wire mesh filter screens are used in crude oil desalting, catalyst recovery, and hydroprocessing units. The high-temperature and corrosion-resistant properties ensure reliable operation in sour gas and high-sulfur environments. Typical mesh range: 50–200 mesh for catalyst bed support and 20–80 mesh for pipeline strainers.
Water & Wastewater Treatment
In municipal and industrial water treatment plants, these screens serve as intake screens, disc filters, and membrane pre-filters. The 316L grade offers excellent resistance to chlorinated water and biofouling. Mesh ratings of 100–400 mesh effectively remove suspended solids down to 40 microns.
Food & Beverage Processing
From juice clarification to beer filtration and edible oil refining, our wire mesh filter screen meets FDA and EU food contact standards. The smooth, non-porous surface prevents bacterial growth and facilitates CIP (Clean-in-Place) cleaning. Mesh sizes 30–150 mesh are common for solid-liquid separation.
Pharmaceutical & Chemical Manufacturing
Critical applications include API crystallization filtration, solvent recovery, and catalyst separation. The ability to withstand aggressive solvents (acetone, MEK, toluene) and high-temperature sterilization (autoclaving) makes these screens indispensable in GMP-compliant facilities.
Mining & Mineral Processing
Heavy-duty wire mesh filter screens (2–20 mesh) are used in dewatering screens, vibrating screens, and tailings filtration. The heavy crimped wire construction resists abrasion from slurries and ensures long service life in harsh mining environments.
Advantages
- Cost-Effective Longevity: Average lifespan of 3–5 years under normal operating conditions, compared to 6–12 months for polymer or ceramic filters.
- Superior Flow Dynamics: The woven structure creates turbulent flow near the mesh surface, reducing cake buildup and maintaining consistent throughput.
- Temperature Adaptability: Functions effectively from cryogenic LNG applications (-196°C) to high-temperature exhaust gas filtration (800°C).
- Chemical Compatibility: Resistant to over 300 chemicals per the Chemical Compatibility Guide, including sulfuric acid, hydrochloric acid, and sodium hydroxide.
- Environmental Sustainability: 100% recyclable metal construction; fully cleanable and reusable, supporting circular economy initiatives.

FAQ
Q1: What is the difference between plain weave and Dutch weave for wire mesh filter screens?
A: Plain weave (1x1) provides uniform openings and is ideal for general straining and particle separation. Dutch weave (warp wires thicker than weft wires) creates wedge-shaped pores that offer depth filtration, higher strength, and better resistance to blinding. For fine filtration (below 50 micron), Dutch weave is typically recommended.
Q2: Can you provide material certifications for your wire mesh filter screens?
A: Yes. All raw materials come with mill test certificates (MTC) per EN 10204 3.1 or 3.2. We can also provide PMI (Positive Material Identification) testing reports upon request for critical applications.
Q3: How do I determine the correct mesh size for my application?
A: The optimal mesh size depends on the particle size distribution of your solids and the desired filtrate clarity. We recommend sending a slurry sample (500 ml) to our lab for a free particle size analysis. Generally, select a mesh with openings 50–70% of the smallest particle to be retained.
Q4: What is the maximum roll width available?
A: Standard roll widths range from 0.5 m to 2.0 m (20" to 78"). Custom widths up to 3.6 m (142") are available for specialized industrial filters. Roll lengths are typically 30 m or 50 m, but we can cut to your exact specification.
Q5: How should I clean a clogged wire mesh filter screen?
A: For light fouling, backwashing with clean water or compressed air (max 6 bar) is effective. For heavy clogging, soak in a suitable cleaning solution (e.g., 5% citric acid for scale, 3% NaOH for organic deposits) and rinse thoroughly. Ultrasonic cleaning at 40 kHz is recommended for fine mesh (above 200 mesh). Avoid using abrasive brushes that may damage the wire surface.
Q6: Do you offer custom framing or end caps for your filter screens?
A: Absolutely. We can weld, crimp, or epoxy your wire mesh filter screen into metal frames (carbon steel, stainless steel, aluminum) or plastic frames (PP, PVDF, PTFE). Additional sealing options include EPDM, Viton, or silicone gaskets for leak-proof installations.
