A stainless steel filter mesh disc quotation is only as accurate as its drawing and parent-mesh specification. “100 micron stainless steel disc” does not tell a manufacturer the outside diameter, center hole, wire diameter, weave, edge treatment, number of layers or required tolerances.
This guide explains how OEM purchasing and engineering teams can prepare a complete stainless steel filter mesh disc drawing and RFQ for cut discs, washer screens and fabricated filtration inserts.
What a Filter Mesh Disc Drawing Must Show
| Drawing item | What the buyer should define | Why it matters |
|---|---|---|
| Finished outside diameter | OD and its permitted tolerance | Determines fit in the assembly |
| Center hole or cutouts | ID, position and number of openings | Controls fit around fittings or shafts |
| Shape | Round, washer, oval, rectangular or custom profile | Defines cutting or forming operations |
| Parent mesh | Clear opening, mesh count, wire diameter and weave | Controls filtration opening and open area |
| Alloy | 304, 316L or another confirmed material | Addresses chemical and fabrication requirements |
| Layers | Single mesh or defined multilayer stack | Changes support and assembly thickness |
| Edge finish | Raw cut, framed, folded, joined or drawing-defined | Affects handling and assembly integrity |
| Acceptance criteria | Dimensions, surface condition and inspection method | Reduces ambiguity during sample approval |
Do Not Confuse Mesh Count With Micron Opening
Mesh count describes openings per linear inch; the actual clear opening also depends on wire diameter and weave. Two products sold under the same mesh count can therefore have different openings. Confirm the parent mesh rather than relying on a generic conversion chart.
For the underlying relationship, see Stainless Steel Filter Mesh: Micron Size vs Mesh Count.
Single-Layer vs Multilayer Disc Specifications
Single-layer discs are made from one specified mesh. A multilayer disc may include a fine filtration layer and one or more support layers. For a multilayer design, define each layer separately, including the stacking order, support geometry and joining method.
Do not assume that adding support layers leaves the flow resistance unchanged. The complete assembly should be assessed for pressure drop, cleanliness and structural performance under the actual operating conditions.
Edge Construction and Installation Fit
A raw-cut woven mesh edge may be acceptable when the disc is clamped inside an assembly. Other applications may require an edge ring, framed construction or a drawing-defined finish. The best choice depends on handling, sealing and whether the edge is exposed to the fluid path.
When the disc sits in a groove or holder, show the relevant mating dimensions. A nominal outside diameter without a tolerance can create fit problems even when the mesh itself is correct.
304 vs 316L: Material Selection Is Separate From Filtration Rating
Both 304 and 316L can be specified with suitable woven openings where available. The material grade should be chosen for the process environment, corrosion requirements, temperature, cleaning method and fabrication steps. 316L may offer improved corrosion resistance in many services, but is not universally corrosion-proof.
Read the 304 vs 316L Stainless Steel Filter Mesh Guide and the main Stainless Steel Filter Mesh product page before confirming material.
From Drawing to Approved Production Sample
- Send the drawing: provide PDF and, where available, an editable CAD file with units and revision number.
- Identify the parent mesh: specify alloy, opening, wire diameter and weave or attach the approved mesh specification.
- Confirm application: state fluid, temperature, differential pressure, cleaning and assembly method.
- Review feasibility: discuss cutting, forming, joining, support layers and any tolerance constraints.
- Approve a sample: inspect fit, dimensions, edge quality and filtration performance as required.
- Release the purchase order: identify the approved drawing revision, quantity, packaging and acceptance criteria.

Frequently Asked Questions
What dimensions should a stainless steel filter mesh disc drawing include?
Show the finished outside diameter, any center or offset holes, cutout locations, thickness or layer stack, edge construction and required tolerances.
Is a micron rating enough to manufacture a mesh disc?
No. Also specify the parent mesh construction, wire diameter, mesh count or clear opening, weave, alloy and finished-part geometry.
Should I choose 304 or 316L for a mesh disc?
Choose based on the actual fluid chemistry, temperature, cleaning method and fabrication needs. Neither grade is universally suitable for all environments.
Can a supplier quote from a physical sample instead of a CAD drawing?
A sample may help identify dimensions and construction, but critical tolerances, material requirements and acceptance criteria should still be documented before production.
What changes when a mesh disc has multiple layers?
The RFQ should identify each layer’s material, mesh specification, stacking order, joining method and required finished dimensions.
