The right metal filter screen mesh for water treatment is selected by matching the filtration objective with the opening, weave, wire diameter, open area, stainless steel grade, pressure conditions, cleaning method, and documentation requirements. Mesh count alone cannot establish filtration performance.At Sunnymetal, we provide stainless steel woven wire cloth in 304, 304L, 316, and 316L grades, with plain, twilled, and Dutch weave options. We also provide stainless steel filter discs and can discuss multilayer sintered mesh structures for suitable process-filtration applications.
