Stainless Steel Woven Wire Mesh

Stainless Steel Woven Wire Mesh

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.

How Mesh Count, Wire Diameter and Opening Work Together

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.

Mesh Count, Aperture, Open Area and Filtration Rating

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

How Is Aperture Calculated for Square Woven Mesh?

For regular square woven mesh, aperture can be estimated from mesh count and wire diameter:

Opening (mm) ≈ 25.4 ÷ Mesh Count − Wire Diameter (mm)

Example: a 20 mesh wire mesh made with 0.40 mm wire:

25.4 ÷ 20 = 1.27 mm 1.27 − 0.40 = approximately 0.87 mm opening

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.

Typical Square Woven Wire Mesh Reference

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.

Stainless Steel Woven Wire Mesh Types

Plain Weave

Each 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 Weave

Warp and weft wires pass over and under multiple adjacent wires, allowing a denser structure and supporting finer mesh combinations.

Plain Dutch Weave

Different warp and weft wire diameters are combined to create a dense filtration structure for pressure filtration and process filtration.

Twill Dutch Weave

A dense twilled filtration structure for finer particle retention and applications that require controlled filtration performance.

Dutch Weave Mesh for Filtration

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.

Important Selection Note Mesh count, aperture and filtration rating are different parameters. Dutch weave mesh should be selected according to its weave structure, warp and weft combination and required particle retention rather than by mesh count alone.
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

Stainless Steel Grade Selection

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

Applications of Stainless Steel Woven Wire Mesh

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

Inspection & Quality Control

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

Stainless Steel Woven Wire Mesh Packaging

Packaging is selected according to mesh fineness, roll size, delivery form and transportation requirements.

•  Roll Mesh: suitable core with waterproof paper, PE film or protective wrapping.
•  Fine Mesh: additional anti-crushing protection to reduce deformation during transport.
•  Cut Sheets: flat stacked with protective separators.
•  Filter Discs: layered or individually protected according to size and quantity.
•  Export Packing: wooden case or pallet when required.

FAQ

What is stainless steel woven wire mesh?

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.

Is mesh count the same as aperture?

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.

Is filtration rating the same as mesh opening?

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.

Which stainless steel grade should I select?

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.

Can woven wire mesh be supplied in custom sizes?

Yes. Depending on the mesh specification, woven mesh can be supplied in rolls, cut sheets, strips, discs and other custom-cut forms.
