Stainless Steel Woven Wire Mesh is made by interlacing warp and weft stainless steel wires into controlled mesh openings. It is widely used for screening, filtration, separation, ventilation, machine protection and fabricated mesh components.
For most buyers, the correct selection starts with the mesh structure and application requirement rather than the stainless steel grade. Mesh count, aperture, wire diameter, open area and weave type determine how the mesh performs, while material grade is selected afterwards according to corrosion environment and service conditions.

Request Mesh Selection & QuoteThe following specification items are the main parameters used to define woven stainless steel wire mesh. Exact combinations depend on weave type, mesh density, wire strength and application requirements.

|---|---|
| Material Grades | 304 / 304L / 316 / 316L / Other agreed stainless steel grades |
| Product Structure | Woven warp and weft stainless steel wire mesh |
| Weave Types | Plain Weave / Twill Weave / Plain Dutch Weave / Twill Dutch Weave |
| Mesh Count | Coarse, medium and fine mesh ranges depending on wire diameter and weave structure |
| Wire Diameter | Specified according to mesh count, opening requirement, rigidity and mechanical strength |
| Aperture / Opening | Clear distance between adjacent wires for regular square woven mesh |
| Open Area | Calculated percentage of open surface area for square woven mesh |
| Filtration Rating | Specified separately for Dutch weave or filter-grade mesh |
| Roll Width | Standard and custom widths available according to mesh structure |
| Roll Length | Standard or custom roll length |
| Delivery Form | Roll / Sheet / Strip / Disc / Custom-Cut Mesh |
| Main Uses | Screening / Filtration / Separation / Ventilation / Protection / Fabrication |

Mesh count alone does not tell you whether a wire mesh is suitable. Wire diameter and mesh opening must be checked together. • Higher mesh count generally produces smaller openings.
• Larger wire diameter increases rigidity and strength but reduces open area.
• Smaller wire diameter increases open area and flow but may reduce mechanical strength.
• Dutch weave mesh should be selected by filtration performance, not mesh count alone.
|
These parameters describe different characteristics of woven wire mesh and should not be treated as the same value.
| Parameter | Definition | Why It Matters |
|---|---|---|
| Mesh Count | Number of openings per linear inch | Describes how dense the mesh is |
| Wire Diameter | Diameter of each woven wire | Affects strength, rigidity and open area |
| Aperture / Opening | Clear distance between two adjacent wires | Determines the approximate screening size |
| Open Area | Percentage of the mesh surface occupied by openings | Affects flow rate, ventilation and screening capacity |
| Filtration Rating | Particle retention capability of the filtration structure | Used for fine filtration and Dutch weave mesh |
| Weave Type | The way warp and weft wires interlace | Changes mesh density, strength and filtration behavior |
For regular square woven mesh, aperture can be estimated from mesh count and wire diameter:
Example: a 20 mesh wire mesh made with 0.40 mm wire:
This calculation is intended for regular square woven mesh. It should not be used as a direct filtration-rating conversion for Dutch weave filter mesh.
The same mesh count can be produced with different wire diameters. Therefore, opening size and open area may vary even when the mesh count is the same.
| Mesh | Wire Dia. (mm) | Approx. Opening (mm) | Approx. Open Area | Typical Weave | Typical Use |
|---|---|---|---|---|---|
| 10 | 0.60 | 1.94 | 58.3% | Plain Weave | Coarse screening and high-flow use |
| 20 | 0.40 | 0.87 | 46.9% | Plain Weave | General screening and separation |
| 40 | 0.23 | 0.405 | 40.6% | Plain Weave | Medium screening and filtration |
| 60 | 0.15 | 0.273 | 41.5% | Plain Weave | Fine screening and filter support |
| 100 | 0.10 | 0.154 | 36.8% | Plain / Twill | Fine particle separation |
Typical reference values only. Final combinations should be confirmed according to required mesh structure, wire diameter and production specification.
Plain WeaveEach warp wire passes alternately over and under each weft wire. It is the most common woven mesh structure for general screening, sieving, ventilation and filtration. |
Twill WeaveWarp and weft wires pass over and under multiple adjacent wires, allowing a denser structure and supporting finer mesh combinations. |
Plain Dutch WeaveDifferent warp and weft wire diameters are combined to create a dense filtration structure for pressure filtration and process filtration. |
Twill Dutch WeaveA dense twilled filtration structure for finer particle retention and applications that require controlled filtration performance. |
Dutch weave mesh is different from ordinary square woven mesh. It normally uses different warp and weft wire diameters and a much denser structure, so filtration performance should be specified separately.
| Parameter | Description |
|---|---|
| Weave Structure | Plain Dutch Weave / Twill Dutch Weave |
| Warp Mesh | Longitudinal wire count and diameter |
| Weft Mesh | Transverse wire count and diameter |
| Filtration Rating | Specified according to required retention performance |
| Typical Use | Liquid filtration / Pressure filtration / Process filtration / Filter media |
The mesh structure should normally be selected first. Material grade can then be chosen according to corrosion resistance, welding requirement and operating environment.
| Grade | Main Characteristic | Typical Selection |
|---|---|---|
| 304 | Good general corrosion resistance and economical cost | General screening, ventilation, protection and filtration |
| 304L | Low-carbon 304 grade | Fabricated or welded mesh components |
| 316 | Molybdenum-bearing grade with improved chloride resistance | Chemical, coastal and more corrosive environments |
| 316L | Low-carbon version of 316 | Chemical, marine and welded filtration equipment |
| Screening Particle grading, sieving and classification | Filtration Liquid, gas and process filtration | Separation Solid-liquid and particle separation |
| Ventilation Airflow screens and grille protection | Machine Protection Safety covers and protective guards | Fabricated Parts Discs, strainers, baskets and cut mesh components |
Woven wire mesh inspection focuses not only on material grade but also on the dimensional and weaving parameters that affect actual mesh performance.
| Inspection Item | Inspection Content |
|---|---|
| Material Grade | Verification of specified stainless steel grade |
| Wire Diameter | Warp and weft wire diameter measurement |
| Mesh Count | Number of openings per inch |
| Aperture | Clear opening measurement for applicable mesh structures |
| Roll Dimensions | Finished width and roll length |
| Weaving Quality | Broken wire, missing wire, uneven weaving and visible surface defects |
| Filtration Rating | Confirmed when specified for filter-grade or Dutch weave mesh |
Packaging is selected according to mesh fineness, roll size, delivery form and transportation requirements.
It is a mesh made by interlacing stainless steel warp and weft wires into a controlled woven structure for screening, filtration, separation, ventilation and protection.
No. Mesh count is the number of openings per linear inch. Aperture is the actual clear distance between adjacent wires. Different wire diameters can produce different aperture sizes even when the mesh count is the same.
Not necessarily. Square woven mesh can be described by actual aperture, while Dutch weave mesh should normally be selected according to filtration rating and particle retention performance.
304 is widely used for general industrial applications. 316 and 316L are commonly considered for chloride-containing, chemical, coastal or marine environments requiring improved corrosion resistance.
Yes. Depending on the mesh specification, woven mesh can be supplied in rolls, cut sheets, strips, discs and other custom-cut forms.
