Materials: 304 / 316L stainless steel; Duplex stainless steel S31803 / S32750 / S32760; Monel 400 / K-500; Inconel 600 / 601 / 625 / 718 / X-750; Hastelloy B-2 / B-3 / C-22 / C-276; Pure nickel N2 / N4 / N6 / N8
Each warp wire alternates over and under successive weft wires. Equal spacing in both directions creates a square opening. Plain weave describes the interlacing pattern; aperture describes the clear space between adjacent wires. These two properties define the filtering surface together.
For square mesh, pitch p = 25.4/N mm, aperture a = p − d, and geometric open area = 100 × (a/p)². N is the number of pitches per inch and d is wire diameter in millimetres. At 20 mesh and d = 0.25 mm, p = 1.27 mm and a = 1.02 mm. At the same count, thicker wire gives a smaller opening and less open area. Geometric aperture is the dimension used for this woven cloth; particle-retention performance also depends on the installed filter and the process.
Rolls provide continuous feed for slitting and cutting. Sheets provide flat blanks for framed screens. Slit strips feed narrow components; cut blanks become filter discs, cylinders and support layers. Woven selvedges retain the edge interlacing, while cut edges define the finished outline. Specify warp direction, the active filtering area and the clamped or welded margin before forming the component.
304 and 316L stainless steel are established choices for the woven medium. The material designation applies to the wire cloth. Frames, rims, support plates, welds and seals are separate component selections. A supported screen combines the chosen cloth opening with the strength and clearances of its backing and installation.
The wire alloy and the weave are specified together. The stainless square-mesh table describes paired geometric constructions; duplex and nickel-alloy cloth use their own grade, mesh count and wire-diameter designation. Plain weave, twill weave and Dutch weave remain separate constructions within an alloy family. Roll, sheet and cut-part drawings identify the chosen construction and material of the filtering cloth.

The wire alloy and the weave are specified together. The stainless square-mesh table describes paired geometric constructions; duplex and nickel-alloy cloth use their own grade, mesh count and wire-diameter designation. Plain weave, twill weave and Dutch weave remain separate constructions within an alloy family. Roll, sheet and cut-part drawings identify the chosen construction and material of the filtering cloth.
| Material family / Grades | Woven construction | Family series | Selection and conversion |
|---|---|---|---|
| Duplex stainless steel / S31803 / S32750 / S32760 | Plain weave | 2–200 mesh | Duplex wire cloth for chemical-process and seawater equipment; specify S31803, S32750 or S32760 individually. |
| Monel / 400 / K-500 | Plain weave; twill and Dutch weave as separate constructions | 2–200 mesh | Nickel–copper alloy cloth for chemical, petrochemical and marine parts; Monel 400 and K-500 remain distinct grades. |
| Inconel / 600 / 601 / 625 / 718 / X-750 | Plain weave; twill and Dutch weave as separate constructions | 2–200 mesh | Nickel-alloy cloth for process and thermal-service components; identify the exact alloy in the wire and welded component specifications. |
| Hastelloy / B-2 / B-3 / C-22 / C-276 | Woven alloy mesh | 2–200 mesh | B-2/B-3 and C-22/C-276 are separate material branches for chemical-process filter parts; specify weave and wire pair for the finished cloth. |
| Pure nickel / N2 / N4 / N6 / N8 | Plain weave; twill and Dutch weave as separate constructions | 1–300 mesh; Ø0.03–1.0 mm | Woven nickel for filtration and conductive components; identify N2, N4, N6 or N8 separately from electroformed nickel screens. |
Mesh-count ranges belong to the material family. The complete designation combines alloy, weave, count and wire diameters. The stainless geometry table and alloy series form separate specification sets.

Square openings separate particles by geometric size in process screening.
The selected cloth opening forms the filtering surface for circulating water and other compatible process liquids.
Cut and formed mesh supplies discs, cylinders and backing layers with a defined aperture.
Each warp wire alternates over and under each weft wire, creating an approximately square aperture. The same mesh count can be woven with different wire diameters and therefore different clear openings.
Delivered a French 316L mesh project specified by approximately 2 mm aperture and at least 56% open area, with material and inspection documentation requested.
Wire diameter determines the remaining clear space. For example, the 10 × 10 rows combine 0.64 mm wire with 1.91 mm aperture, or 0.51 mm wire with 2.03 mm aperture.
Plain square weave has visible square openings. Plain Dutch weave uses different warp and weft wire sizes and closely packed wires to form a tortuous filtration path.
Specify the active mesh area, outer dimensions, wire direction, edge treatment and the clamping or weld margin. The frame and support are dimensioned separately.
