Wire Mesh for Filtration & Sieving
Fine woven mesh and filter cloth for separating solids from liquids, gases, and each other. From coarse scalping screens down to micron-level filtration in 304 and 316 stainless — cut to size and custom-fabricated in Hayward, California since 1938.
Filtration is one of the most demanding jobs a wire mesh can do. The right cloth has to hit a target particle size, hold up to pressure and flow, and resist whatever fluid or chemistry is passing through it. We stock a wide range of woven wire mesh counts and weaves so you can dial in the balance of filtration rating, open area, and strength your process needs — then we cut it to your dimensions or fabricate finished discs and packs.
Start With Your Micron Target
The first question in any filtration job is: what particle size are you trying to catch or pass? Mesh count alone does not tell the whole story — wire diameter changes the opening, and different weaves behave differently. Use our mesh-to-micron conversion chart to translate between mesh count, opening size, and microns, then talk to us to confirm the right specification.
| Filtration Style | Typical Range | Best For |
|---|---|---|
| Coarse woven mesh | Above ~150 microns | Scalping, pre-filtration, straining, sieving |
| Fine woven mesh | ~40–150 microns | General liquid & air filtration, screening |
| Plain Dutch weave | ~25–100 microns | Higher-strength fine filtration |
| Twilled Dutch weave | Down to ~10 microns | High-pressure, fine liquid/gas filtration |
Ranges are general guidance only — exact ratings depend on mesh count, wire diameter, and weave. Confirm your spec with us before ordering.
Weaves For Filtration
Square (Plain) Weave
Warp and weft wires cross one-over-one for uniform, predictable square openings. The workhorse for sieving, screening, and everyday liquid and air filtration where you can see and measure the aperture directly.
Plain Dutch Weave
Warp and weft wires are different diameters and packed tight, creating a dense cloth with very small, wedge-shaped pores. Delivers fine filtration with more strength and rigidity than an equivalent open weave.
Twilled Dutch Weave
A two-over-two twill on a Dutch construction, allowing even finer, heavier wires and tighter pores. Handles higher differential pressure and reaches the finest filtration ratings we offer.
Materials For The Job
Most filtration work runs in stainless steel for corrosion resistance and cleanability. 304/304L is the everyday choice; 316/316L adds molybdenum for better resistance to chlorides and aggressive media, so it is the common pick for marine, food, pharmaceutical, and harsher chemical service. For specialized chemical environments we can also source monel and nickel. Browse woven mesh on our woven wire mesh collection, or jump straight to 316 stainless woven mesh.
Typical Uses
Liquid Filtration
Straining, clarifying, and separating solids out of water, oils, coolants, fuels, and process fluids — from inline strainers to filter housings.
Air & Gas Filtration
Particulate capture, venting, and separation in air, gas, and vapor streams where you need airflow with mechanical strength.
Sieving & Screening
Particle sizing, grading, and separation of powders, granules, and slurries by mesh opening — lab test sieves through production screening.
Extruder & Filter Screens
Screen packs for plastics extrusion and polymer processing, plus custom filter screens that protect pumps, nozzles, and downstream equipment.
Filter Discs & Packs — Cut To Size
We do more than sell mesh by the roll. Our shop cuts filter discs, rounds, rectangles, and multi-layer packs to your dimensions, and we can combine a fine filtration layer with coarser support mesh for added strength. Send us a diameter or a drawing along with your target micron and material, and we will quote finished parts ready to drop into your housing or screen changer.
Not sure which mesh filters your particle size?
Tell us your micron target, fluid, and dimensions — we will spec the cloth and quote cut parts.
Filtration FAQ
What micron rating do I need?
It depends on the smallest particle you need to stop (or pass) and how much flow and pressure your process runs. Start with the particle size, then use our mesh-to-micron conversion chart to find candidate meshes. If you are unsure, tell us what you are filtering and we will help narrow it down — call (510) 887-8787 or send us the details.
Dutch weave or plain square weave — which is better for filtration?
Plain square weave gives you clean, measurable, uniform openings and is ideal for sieving and general filtration. Dutch weaves (plain and twilled) pack the wires tighter for much finer pore sizes with greater strength and pressure resistance, so they are the choice for fine liquid and gas filtration where a standard open weave would be too fragile. Twilled Dutch reaches the finest ratings.
Do you cut filter discs and custom shapes?
Yes. Custom fabrication is what we do — we cut filter discs, rounds, and other shapes to size, and can build multi-layer screen packs with a support mesh backing. Send dimensions or a drawing with your target micron and material for a quote.
304 or 316 stainless for my filter?
304/304L handles most general filtration well. Choose 316/316L when you are dealing with chlorides, saltwater, food and pharmaceutical processing, or more aggressive chemistry, thanks to its added corrosion resistance. For specialized chemical service we can also source monel and nickel — ask us about your media.
Can you ship nationwide?
Yes. We are based in Hayward, California and ship cut mesh and fabricated filter parts across the country. Contact us or call (510) 887-8787 to place an order.
