This page covers the 200 mesh count of plain weave wire mesh: the woven specification per ISO 9044 / ASTM E2016, the particle size it retains, the open area it presents to flow, and the neighbouring counts to step to when the separation requires it.
200 Mesh Specification Row (ISO 9044 / ASTM E2016)
| Mesh count | Wire diameter (mm) | Aperture (mm) | Micron rating (u00b5m) | Open area (%) | Weight SS (kg/mu00b2) | Reference standard |
|---|---|---|---|---|---|---|
| 200-Mesh | 0.053 | 0.074 | 74 | 34.0 | 0.29 | ISO 9044 |
200 Mesh to Micron & Aperture
| Openings per inch | 200 |
|---|---|
| Aperture (opening width) | 0.074 mm |
| Micron rating | 74 µm |
| Standard wire diameter | 0.053 mm |
| Open area | 33.9 % |
Aperture = (25.4 mm ÷ mesh count) − wire diameter. The micron rating equals the aperture in micrometres; actual retention also depends on particle shape and cake formation.
Wire Diameter Options at 200 Mesh
| Option | Wire dia | Aperture | Micron | Open area | Weight (SS) |
|---|---|---|---|---|---|
| Heavy wire | 0.069 mm | 0.058 mm | 58 µm | 20.9 % | 0.49 kg/m² |
| Standard wire | 0.053 mm | 0.074 mm | 74 µm | 34.0 % | 0.29 kg/m² |
| Fine wire | 0.040 mm | 0.087 mm | 87 µm | 47.2 % | 0.16 kg/m² |
Heavier wire adds strength and abrasion life but closes the aperture; finer wire opens the aperture and raises throughput at the cost of durability. Specify mesh count AND wire diameter to fix the aperture unambiguously.
Open Area & Flow at 200 Mesh
The standard 200 mesh weave presents an open area of about 33.9%. A common design rule is to keep the clean-mesh approach velocity low enough that initial pressure drop is negligible; the mesh then acts as the cake support.
200 Mesh Cloth Weight
Standard 200 mesh stainless cloth weighs approximately 0.29 kg/m² (density 7.93 g/cm³ basis; brass and copper weave roughly 10% heavier, aluminum about one third). Use this figure for roll handling and freight estimation.
Typical Applications for 200 Mesh Plain Weave Wire Mesh
200 mesh plain weave wire mesh is commonly specified for liquid filtration and clarification, extruder screen packs, hydraulic and fuel strainers, pharmaceutical and food sieving, and laboratory test work.
Plain, Twill or Dutch Weave at This Rating?
At this fineness, compare plain weave against twill (heavier wire, more durable) and dutch weave (higher strength, pressure-resistant, nominal rather than absolute rating) before finalizing the specification.
What Plain Weave Wire Mesh Does
General screening, sieving and filtration with square-aperture stainless steel wire mesh, where each wire passes alternately over and under the next — the most widely used woven wire cloth from coarse 2 mesh to fine 635 mesh.
Fitting & Care
- Cut on a guillotine or with sharp shears and bind or weld the edges of fine cloth so wires do not unravel.
- Support fine stainless steel wire mesh with a coarse backing screen whenever it filters against pressure.
