Stainless Steel Filter Mesh

Dashang stainless steel filter mesh strictly complies with ASTM E2814 (Standard Specification for Metal-Mesh Filter Media) and GB/T 21648 (Industrial Woven Wire Filter Mesh) standards. Manufactured from high-quality stainless steel grades such as SUS304, 304L, 316, 316L, 321, and 904L, the mesh is precision-woven to deliver exceptional resistance to acids, alkalis, corrosion, high temperatures, and high pressures. 

Dashang stainless steel filter mesh offers filtration ratings ranging from 2 μm to 300 μm, meeting requirements across the entire spectrum from coarse to fine filtration:

Coarse filtration (100 μm – 300 μm): Solid-liquid separation of large particles, primary water filtration

Medium-precision filtration (10 μm – 100 μm): Oil filtration, clarification of chemical liquids

High-precision filtration (2 μm – 10 μm): Aviation hydraulic fluid purification, sterile pharmaceutical filtration, food-grade precision filtration

Three mainstream types of Dutch weave, each with unique filtration characteristics:

Unlike the "sieving" principle of square-mesh screens, Dutch weave mesh relies on the difference in diameter between warp and weft wires to create a deep-filtration structure, achieving "absolute filtration"—meaning particles larger than the nominal rating are completely intercepted rather than passing through based on probability. The tortuous flow paths characteristic of twill Dutch weave further enhance this capability; the winding channels ensure that particles are captured from multiple directions as they pass through, resulting in a retention efficiency of up to 99.9%.

Dashang filter screens offer not only precise filtration capabilities but also exceptional performance for long-term service under extreme operating conditions:

High-Temperature Resistance: Suitable for filtering high-temperature gases or liquids (304/316L ≤ 450°C; 321 ≤ 800°C); maintains structural stability and mesh integrity during processes such as high-temperature chemical reaction filtration and molten metal filtration.

High-Pressure Resistance: Capable of withstanding high differential pressures; suitable for applications such as high-pressure hydraulic systems and water injection filtration in oil extraction.

High Load-Bearing Strength: Made from high-strength, high-toughness stainless steel wire, offering excellent tensile, compressive, and impact resistance; withstands continuous impact in dynamic equipment like vibrating screens and pressure filters.

Corrosion Resistance: Highly resistant to rust during long-term use in corrosive environments—including acid/alkali washing, salt spray, and marine settings—making it ideal for seawater filtration and the processing of chemical media.

By maintaining stable filtration performance under high-temperature, high-pressure, and corrosive conditions, these screens significantly reduce unplanned downtime and the frequency of filter media replacement, resulting in a total cost of ownership that is substantially lower than that of standard filter materials.

Dashang Wire Mesh possesses extensive experience in the production of Dutch weave mesh and maintains a diverse inventory, ranging from common specifications—such as 12×64 mesh and 24×110 mesh—to high-precision Dutch weave products. Our stainless steel filter mesh is widely used in polymer processing, plastic recycling, chemical screening, and other industrial filtration systems; we are also a designated supplier for manufacturers of high-precision filters.
