Sintered Wire Mesh Layer Structure & Specification Guide
Sintered wire mesh is a bonded laminate of selected woven-wire layers. Specify each layer by function and construction, list the sequence from upstream to downstream, mark normal and reverse flow, and define the rating, permeability, thickness and finished-element duty separately.
Direct Answer: A Layer Count Is Not a Complete Specification
Filtration layer
The designated woven layer provides the primary retention function under a stated rating basis.
Protection layer
A selected screen can protect finer media from handling or reverse-flow damage.
Distribution / drainage
An intermediate layer can separate meshes, spread flow and provide a drainage path.
Structural support
Coarser mesh provides stiffness relative to the pressure direction and finished geometry.
Not every laminate needs every function, and one layer may contribute more than one function. Do not purchase from the phrase “five-layer sintered mesh” alone.
Sintered Wire Mesh Layer Function Matrix
Use functional names to explain the design, then attach measurable construction data. A functional label cannot replace mesh count, wire diameter, weave, thickness or test basis.
| Layer function | What to record | Question it answers |
|---|---|---|
| Protection | Weave, mesh/wire data, side and relation to fine media | What shields the filtration layer during handling or reverse flow? |
| Filtration control | Complete weave construction plus rating and named test basis | Which layer owns the stated retention requirement? |
| Distribution / drainage | Opening, wire, position and separation function | How is flow spread or a fine layer separated from support? |
| Support | Mesh/opening, wire, quantity, side and pressure direction | What resists deformation under the specified load? |
| Complete laminate | Order, material, total thickness, tolerances and orientation | What exact bonded medium is being purchased? |
How a Typical Layer Sequence Is Read
A drawing should list the laminate from the named upstream face to the downstream face. One possible sequence is protection mesh → filtration-control layer → distribution/drainage layer → structural support. This is only an example; the required layer count and sequence depend on the duty.
Normal flow, reverse cleaning and the side exposed to higher differential pressure must be marked. Use the differential-pressure RFQ guide to separate clean resistance from structural loading.
Why ‘Five-Layer Sintered Mesh’ Is Still Incomplete
Weave is unknown
Square, Dutch or another construction changes opening and pore path.
Wire data is unknown
The same mesh count can use different wire diameters and open area.
Order is unknown
Reversing a directional layer stack can change support and protection behavior.
Test basis is unknown
A micron number without a definition cannot be compared reliably.
For rating definitions, use the nominal vs absolute micron-rating guide. For retention location and loading behavior, review surface vs depth filtration.
Rating, Permeability and Strength Are Separate Requirements
Retention needs a stated opening, pore/rating definition or named test. Permeability or clean pressure drop needs a fluid or gas, temperature, flow, area and test condition. Mechanical duty needs normal, maximum and reverse differential pressure plus the finished geometry, seams and interfaces.
Equal micron values do not prove equal flow. Compare the complete medium using the permeability vs micron-rating guide.
Layer Structure vs Finished Filter Form
Flat disc
Layer orientation, OD/ID, edge, seal and active area define the finished flat component.
Cylindrical cartridge
Forming, seam, support, ends and seals are added to the bonded medium.
Custom shape
Cutting and forming must preserve the specified layer order and equipment interface.
Use the sintered wire mesh filter disc page for flat product procurement. Use the sintered filter cartridge page for complete cylindrical elements.

Sintered Wire Mesh Drawing and RFQ Checklist
1. Define duty
Fluid/gas, particles, temperature, flow, pressure and cleaning.
2. Define retention
Rating value plus geometric, nominal, absolute or named test basis.
3. List every layer
Material, weave, mesh/wire construction, function and sequence.
4. Mark orientation
Upstream/downstream faces, normal flow and reverse conditions.
5. Define the part
Thickness, geometry, tolerances, seams, edges, ends and acceptance.
For finished-part controls, use the filter-element drawing and tolerance checklist. If the porous medium family is not yet selected, compare sintered powder and sintered wire mesh.
Sintered Wire Mesh Layer Structure FAQ
A design may include a filtration-control layer plus protection, distribution or drainage layers and one or more structural supports. The functions, count and sequence are design-specific; five layers is common terminology, not a universal formula.
The designated filtration-control layer normally provides the main retention function, but the stated rating still needs a geometric, nominal, absolute or named test definition. Finished-element bypass and damage can also affect performance.
Layer functions are directional. The protection layer, fine filtration layer and support may need a defined upstream-to-downstream order relative to normal and reverse differential pressure.
No. A layer count does not define the weave, mesh and wire data, layer order, filtration rating, permeability, thickness or support duty. Record every layer and its function.
Mark upstream and downstream sides; list each layer in order with material, weave or complete mesh construction; identify the rating/test basis, total thickness, dimensions, tolerances, joining and finished-element interface.
No. Flow resistance and structural behavior depend on the complete medium, fluid or gas, flow, temperature, area, geometry, differential pressure, support, seams and ends. Request comparable data under stated conditions.
