In industries such as petrochemicals, plastic extrusion, food and pharmaceuticals, and water treatment,stainless steel filter screens serve as core filtration components, and their performance directly impacts production efficiency and product purity.  With the wide variety of specifications available on the market, how do you choose the product best suited to your specific working conditions?

        Beijing Jin Hai Zhong Da (Sunny Metal Group), a seasoned expert in metal wire mesh, has summarized four key dimensions to consider when selecting stainless steel filter screens.

        Ⅰ. Material determines lifespan: 304 or 316L stainless steel filter disc?

        The corrosion resistance of stainless steel is a cornerstone of engineering safety.

        • 304 Stainless Steel Mesh:Offers good processing performance and oxidation resistance,suitable for general water treatment,building protection,and the food industry.

        • 316/316L Stainless Steel Mesh:Contains molybdenum (Mo), significantly enhancing its resistance to chloride corrosion and acid/alkali environments.

        If your application involves seawater environments, strong chemical acids and bases, or high-precision medical equipment, 316L is the essential choice for ensuring long-term durability.

        Ⅱ. Mesh Count and Pore Size: The Core of Precise Filtration

        Mesh count refers to the number of holes per inch of length.A higher mesh count indicates smaller hole size and finer filtration.

        • Coarse filtration: Suitable for preliminary screening of larger solid particles.

        • Fine filtration:Sunny Metal offers ultra-fine stainless steel wire mesh with mesh counts reaching several hundred, suitable for high-precision filter presses.

        • Key point:When selecting a filter, it's crucial to consider not only the mesh count but also the opening area. A high opening area effectively reduces filtration resistance and increases fluid throughput while maintaining accuracy.

        Ⅲ. Weaving technique: Plain weave, twill weave, or Dutch weave stainless steel mesh dics?

        • Plain Weave:The most commonly used structure, with uniform mesh openings and good stability.

        • Twilled Weave:Allows for the use of thicker wire diameters for high-mesh weaving, increasing the pressure resistance of the filter screen.

        • Dutch Weave (Stainless Steel):Features different wire diameters in the warp and weft directions, forming a dense filtration layer. It is an ideal choice for high-pressure vacuum filters, fuel filtration, and hydraulic systems.

        Ⅳ. Advanced processing: from wire mesh to filter elements

        To meet the diverse installation requirements of different mechanical equipment, Sunny Metal offers a wide range of customized services:

        • Stainless Steel Filter Discs: Precisely stamped with smooth, burr-free edges.

        • Multi-layer Edge-bound Filter Screens:Different mesh sizes are combined using spot welding technology to achieve multi-stage filtration, significantly extending the replacement cycle.

        Q1: How to quickly distinguish between 304 and 316 stainless steel filter screens?

        A: It's difficult to tell them apart with the naked eye. The most professional method is to use a photospectral analyzer (PMI) to test the chemical composition (316 contains 2%-3% molybdenum).For simple on-site testing,a stainless steel identification solution can be used.

        Q2: What is the difference between Dutch Weave and regular plain weave wire mesh?

        A: Regular plain weave wire mesh has the same warp and weft diameters and square mesh openings; while Dutch Weave wire mesh has different warp and weft diameters, arranged tightly like satin, with no straight mesh openings. Dutch Weave wire mesh has a more robust structure, is suitable for high-pressure filtration environments, and can capture finer impurities, making it the preferred choice for hydraulic systems and fuel filtration.
