Custom Stainless Steel Edged Filter Discs
An edged filter disc combines selected wire mesh with a controlled metal perimeter. The rim contains cut wire edges, keeps layers aligned and creates a repeatable installation interface. A useful RFQ defines both the filtration media and the finished rim cross-section.
Why Add an Edge or Rim?
Contain cut wires
The perimeter encloses exposed mesh edges for safer handling and assembly.
Align multiple layers
A rim helps preserve the specified order of fine, drainage and support layers.
Control equipment fit
Finished OD, thickness and rim profile form part of the mounting interface.
Improve handling stability
The framed perimeter reduces distortion during packaging and installation.
Edged Filter Disc Specification Checklist
Do not specify only the outside diameter and mesh count. Finished thickness, rim width, mesh wire diameter, layer sequence and tolerances are equally important for repeatable fit.
| RFQ field | What to specify | Why it matters |
|---|---|---|
| Filter media | Material, weave, mesh count plus wire diameter/aperture | Defines opening, retention and flow behavior |
| Layer stack | Every layer, sequence, support and flow direction | Prevents ambiguity in multilayer construction |
| Finished geometry | OD/ID, shape, thickness, flatness and tolerances | Controls installation fit and sealing |
| Rim specification | Material, width, profile, joint and cross-section | Defines edge containment and active area |
| Operating context | Medium, temperature, differential pressure, cleaning and quantity | Supports construction and material review |
Rim Profile and Finished Dimensions
The rim may be formed, folded, welded, bonded or made to another drawing-defined construction. Its width and cross-section reduce the active filtration area and affect total thickness.
Provide a section view showing how the mesh is captured, where any joint is permitted and which dimensions contact the housing.
Annular and Center-Hole Edged Filter Discs
An annular filter disc adds a controlled center opening and usually requires both an outer and inner edge treatment. The inside diameter is not merely a cutout: it can locate around a shaft, surround a flow passage or form part of a sealing interface. Quote it from a sectioned drawing rather than from OD and ID alone.
| Annular-disc field | Drawing requirement | Why it matters |
|---|---|---|
| Outside diameter | Finished OD, tolerance and locating/sealing role | Controls housing fit and outer contact |
| Inside diameter | Finished ID, tolerance and relation to the shaft or passage | Controls central clearance and inner contact |
| Concentricity | Datum and permitted OD-to-ID offset | Keeps the annular filtration band correctly positioned |
| Inner and outer rims | Separate width, profile, material, joint and finished thickness | Defines mesh capture and sealing interfaces |
| Active mesh band | Usable radial width after both rims and solid margins | Prevents flow area being estimated from OD alone |
| Layer alignment | Center-hole alignment, layer order, support and joining | Prevents exposed or displaced layers at the inner edge |
Inner Rim, Outer Rim and Sealing Contact
Outer locating rim
Define whether the OD locates, seals or simply clears the housing.
Inner center-hole rim
Show how mesh layers terminate around the ID and what surface contacts the mating part.
Active annular area
State the usable mesh band after both rims, supports and solid margins.
For a complete drawing-control framework, use the filter element drawing and tolerance checklist. It helps separate critical fit dimensions from reference dimensions.
Mesh Media and Layer Combinations
Fine filtration layer plus support
Stainless steel wire mesh can be specified by weave, mesh count, wire diameter and aperture. Fine mesh may be paired with coarse woven mesh or perforated support when required by the assembly.
Use the mesh-to-micron calculator only for appropriate square woven constructions. List the complete layer sequence from upstream to downstream.

Edged Disc vs Plain and Sintered Disc
Plain-cut disc
Lowest-complexity cut mesh with exposed edges captured by the housing.
Edged filter disc
Perimeter is contained to improve handling, layer alignment and equipment fit.
Sintered mesh disc
Diffusion-bonded laminate forms an integrated rigid porous structure for suitable duties.
Compare the main stainless steel filter disc range and the dedicated sintered wire mesh filter disc. For polymer melt screen assemblies, see stainless steel extruder screen packs.
Edged Filter Disc RFQ Workflow
1. Define retention
State the particle target and rating basis.
2. Specify every layer
List weave, mesh, wire diameter/aperture, material and sequence.
3. Define the rim
Provide rim material, width, profile, joint and finished thickness.
4. Confirm equipment fit
Show OD/ID, tolerance, flatness and sealing or mounting faces.
5. Complete the RFQ
Add operating conditions, cleaning, quantity and drawing.
Stainless Steel Edged Filter Disc FAQ
An edged filter disc is a flat woven mesh or multilayer screen whose perimeter is contained by a formed, folded, welded or bonded rim. The rim improves handling and defines the installation interface.
State rim material, outside diameter, finished thickness, rim width, profile, seam or joint, exposed-edge requirement and dimensional tolerances. A cross-sectional drawing is preferred.
Yes. Fine filtration mesh can be combined with coarse woven support or perforated backing. List every layer in sequence and identify flow direction and joining requirements.
Yes. The rim, solid margins and supports occupy part of the disc face. Compare effective active area rather than calculating flow from the outside diameter alone.
Provide material, weave, mesh count with wire diameter or clear aperture. For Dutch weave, use the full warp and weft construction and a stated rating basis rather than a square-mesh formula.
Round discs are common, but rectangular, oval, annular and profile-shaped screens can be reviewed from a drawing. Critical dimensions, corner radii and orientation features should be shown.
Specify finished outside diameter, finished inside diameter, concentricity, total thickness, outer-rim and inner-rim cross-sections, active mesh width, sealing contact areas and tolerances. Also identify which diameter locates the part in the assembly.
