What Is Stainless Steel Wire Mesh?
Stainless steel wire mesh is a durable mesh product made by weaving stainless steel wires in a set pattern or by welding them at their crossing points. It is used for screening, straining, separation and filtration in the food, chemical, pharmaceutical, plastics, mining, automotive, laboratory and machinery industries.
Our wire mesh is woven on wire looms in several weave types. AISI 304 grade mesh contains 18% chromium and 8% nickel. AISI 316 grade mesh contains 18% chromium and 10% nickel plus 2% molybdenum, which makes it markedly more resistant to salt water and acids than other stainless grades.
Because stainless mesh withstands high temperatures, it is ideal for hot processes where filter media with a low temperature limit, such as polypropylene, cannot be used. It also releases nothing into the process, so it is preferred in food, pharmaceutical and drinking water applications.
What does mesh mean?
Mesh is the number of openings in one linear inch (25.4 mm). The higher the mesh count, the smaller the aperture and the finer the filtration. Because different wire diameters can be used at the same mesh count, the mesh number alone is not enough: real straining performance has to be judged together with the wire diameter and the aperture in microns. For example, 20 mesh gives a 1,020 micron aperture with 0.25 mm wire and an 820 micron aperture with 0.45 mm wire.

Weave Types
Our stainless filter mesh is woven in four ways: PLAIN, DUTCH, TWILLED and TWILLED DUTCH. Plain weave is the type most commonly used in filtration.
Plain — square-aperture plain weave
The most common type. Each wire passes alternately over and under the next, forming square apertures that can be measured by eye. Used for general screening, straining and machine protection.
Twill — twill weave
Each wire passes over two wires and under two. Because it allows thicker wire at the same aperture, it gives a higher wire density and smaller openings. Preferred for applications that need high pressure resistance.
Dutch — Dutch weave
The warp and weft wires have different diameters, so the aperture is much smaller than in plain weave. Used where fine filtration at micron level is needed; it reaches straining ranges that plain weave cannot.
Twilled Dutch — twilled Dutch weave
The twill version of Dutch weave. Used in processes that need fine micron ratings and high-pressure filtration.
Welded, crimped and pressed wire mesh
Welded mesh, with its wires welded at the crossing points, is more rigid and suits heavy-duty applications. Crimped and pressed mesh is used in mining, quarrying and guarding applications that need larger apertures and high mechanical strength. These types are assessed project by project.
Welded Wire Mesh
The wire crossings are welded; its rigid structure suits heavy-duty, guarding and conveying applications.
Crimped Wire Mesh
The wires are crimped into a wave before weaving, which keeps the aperture stable with thick wire. Used in mining and quarry screens.
Pressed Wire Mesh
The crossing points are pressed and locked; used for screening that needs high mechanical strength and a flat surface.
Mesh – Micron – Wire Diameter Selection Table
The table below shows the actual aperture, open area and openings per square centimetre for each mesh count at different wire diameters. As the open area rises, flow rate increases and pressure drop falls; thicker wire increases mechanical strength but reduces open area.

Dry screening304 or 316? Decision Guide
For general, dry or slightly humid environments, AISI 304 is usually enough. For salt water, sea air, chlorides, heavy chemical contact or processes where hygiene is critical, AISI 316 / 316L is the safer choice. Where screening involves heavy impact or heavy material, wire diameter, support structure and weave type matter as much as the grade.
- Dry Food Screening (Flour, Sugar, Coffee)
- Recommended Grade: AISI 304 (plain weave).
Why: Low corrosion risk; suitable for food contact, hygienic and economical. - Salt Water and Seawater Filtration
- Recommended Grade: AISI 316 or 316L.
Why: Molybdenum prevents pitting corrosion caused by salt and chlorides. - Pharmaceutical and Biotechnology Processes
- Recommended Grade: AISI 316L low-carbon alloy.
Why: Very smooth surface, easy sterilisation and full compatibility with CIP/SIP lines. - Plastic Injection and Polymer Melt
- Recommended Grade: AISI 304 (thick or reinforced wire).
Why: Keeps its shape under high temperature and pressure and releases nothing into the melt. - Acidic Chemicals and Electrolysis Baths
- Recommended Grade: AISI 316.
Why: Markedly higher acid resistance; extends bath life. - Mining, Aggregate and Heavy-Impact Screening
- Recommended Grade: AISI 304 (thick wire / crimped or pressed mesh).
Why: Wire diameter and pressing maximise resistance to impact and abrasion.

What is the difference between mesh and micron?
What is the difference between AISI 304 and AISI 316 wire mesh?
AISI 304 wire mesh contains 18% chromium and 8% nickel. AISI 316 contains 18% chromium and 10% nickel plus 2% molybdenum, which increases resistance to salt water and acids. AISI 316 is preferred for seawater, chloride environments and chemical and pharmaceutical processes; AISI 304 for general and dry applications.
What is the finest micron rating available?
Our plain square weave mesh ranges from 4 to 325 mesh (down to 43 µm); 5 µm is achieved with Dutch and Twilled Dutch weaves. Tell us the micron rating you need and we will choose the right weave and grade together.
