Micron-Based Mesh Procurement

Micron Stainless Steel Mesh for Industrial Filtration

Maidong reviews micron stainless steel mesh requirements as a complete industrial specification. State whether the micron value means a geometric opening or a tested retention rating, then add weave, wire geometry, alloy, dimensions, operating duty and finished form.

First Define What the Micron Number Means

Geometric aperture

A measured or calculated clear opening in square woven mesh.

Nominal rating

A stated retention efficiency under defined test conditions.

Absolute rating

A stricter retention threshold that still needs a method and efficiency definition.

Pore or test value

A construction-specific result used for Dutch weave, sintered or multilayer media.

This product page focuses on selecting and purchasing micron mesh within the broader stainless steel wire mesh range. Use the mesh-to-micron calculator for square-mesh geometry. Nominal and absolute values must be tied to their own definitions and test basis.

Micron Stainless Steel Mesh Specification Table

A micron value alone cannot define the product. Use the complete RFQ structure below when comparing quotations.

RFQ fieldWhat to specifyWhy it matters
Micron basisAperture, nominal/absolute rating, pore value or named methodPrevents unlike values being treated as equivalent
Mesh constructionPlain/twill square or Dutch weave; full count designationIdentifies the pore path
Wire geometryMesh count and wire diameter, or warp/weft detailsDefines opening, strength and open area
Material304, 304L, 316, 316L or drawing-specified alloyMust suit process and cleaning chemistry
Supply formRoll, slit width, cut piece, disc, cylinder or drawingDefines dimensions, edges and fabrication
Process dutyMedium, viscosity, temperature, flow, pressure and cleaningConnects the mesh to real operation
AcceptanceTolerances, inspection basis, quantity and required documentsCreates a comparable purchase requirement

Square-mesh aperture depends on mesh pitch and wire diameter together.

Square Woven Mesh: Calculate Aperture From Two Inputs

For square woven mesh, nominal aperture equals mesh pitch minus wire diameter. Two products with the same mesh count can therefore have different openings and open areas.

Use fine stainless steel wire mesh when the purchasing requirement is specifically a fine square opening. The mesh count, wire diameter and aperture tolerance should be stated together.

Choose the Pore Structure, Not Just a Micron Label

Plain square weave

Direct square openings with straightforward geometric aperture.

Twill square weave

A different wire path used for selected fine-wire combinations.

Dutch weave

Dense warp/weft construction with an indirect filtration path.

Supported media

Fine layer combined with coarse mesh or perforated support where required.

For Dutch constructions, do not apply the square-opening conversion formula. Use the Dutch weave mesh micron-rating guide and request the full construction plus rating method.

Material Selection: 304, 304L, 316 or 316L

The material grade does not set the micron value. Select alloy from the process medium, concentration, temperature, cleaning chemistry, fabrication and governing specification.

For general woven-mesh procurement, see the stainless steel wire mesh supplier page. For media selection in filtration systems, use stainless steel mesh for filtration.

Supply Forms and Finished Micron Mesh Components

Mesh rolls

State width, length, edge, handling and dimensional tolerance.

Slit and cut mesh

Define width or outline, orientation, edge quality and quantity.

Filter discs

Add diameter, layers, support, rim, tolerance and flow direction.

Cylinders and assemblies

Provide OD/ID, length, seam, ends, support and equipment interface.

Fine stainless steel wire mesh supplied in rolled form
Roll width, length, edge and handling requirements should be included in the RFQ.

Finished-form RFQs need a drawing

The same micron media can behave differently after forming, layering or installation. Review stainless steel filter discs and stainless steel filter cylinders for drawing-based component requirements.

A perforated support can add rigidity but does not define the filtration rating of the fine media.

Perforated support

These product examples illustrate media and support choices, not guaranteed micron ratings or stock availability. Final supply follows the agreed construction, drawing and acceptance basis.

Typical Industrial Selection Contexts

Liquid filtration

Specify fluid, viscosity, particle target and pressure conditions.

Oil and hydraulic duty

Add cleanliness objective, flow, temperature and pressure drop.

Gas and air screening

Define particles, flow, temperature and support requirements.

OEM filter elements

Connect the media specification to the complete component drawing.

How to Prepare a Micron Mesh RFQ

1. Define the target

State the particle size or separation objective.

2. Define micron basis

Aperture, nominal, absolute, pore value or named test.

3. Select construction

Choose weave, wire geometry, material and support.

4. Define finished form

Give roll, cut piece or component drawing details.

5. Set acceptance

Add tolerances, inspection, quantity and process data.

Request a Specification Review

Send the micron value and definition, weave, wire geometry, grade, dimensions, finished form, process duty and quantity. If the rating method is unknown, describe the filtration objective instead of assuming an equivalence.

Micron Stainless Steel Mesh FAQ

It usually means stainless steel mesh selected for a target opening or filtration value stated in micrometres. The value must be identified as geometric aperture, nominal rating, absolute rating or another named test basis.

For square woven mesh, nominal aperture can be calculated only when both mesh count and wire diameter are known. Mesh count alone is insufficient, and the square-mesh formula does not apply to Dutch weave.

Not automatically. A 50 μm geometric opening describes pore geometry, while a 50 μm filtration rating describes retention under a definition or test. Ask which value is being quoted.

304, 304L, 316 and 316L are common industrial enquiries. The correct grade depends on process chemistry, temperature, cleaning, fabrication and the governing material requirement.

Requirements can be reviewed for rolls, slit widths, cut pieces, discs, cylinders and supported assemblies. Finished parts need drawings, tolerances, layer sequence, seams, edges and flow direction.

Provide the micron value and its basis, weave, mesh count and wire diameter where applicable, grade, dimensions, tolerances, supply form, medium, temperature, pressure differential, cleaning method and quantity.
