How to use this result

Results are mathematical candidates, not an assertion that every combination is routinely manufacturable.

Check the units

Keep the drawing, quotation and purchase order in one defined unit system.

Copy the assumptions

A useful result includes the inputs, formula basis and any material density used.

Confirm manufacturability

Ask the supplier to confirm wire tolerance, aperture tolerance, weave and edge condition.

What to confirm

Submit the result with the application, dimensions, quantity and operating conditions if you want a human specification check.

What the candidate table actually means

The finder does not pretend to know a supplier’s stock list. It solves the wire diameter required to produce the target opening at each integer mesh count in the range you define, then filters by your wire limits and minimum open area.

Worked interpretation

Treat each row as an exact mathematical candidate. Preferred wire series, weaving stability, tolerance class, tooling and commercial availability still require supplier confirmation. A shorter candidate list is usually more useful than a long list built from unstated assumptions.

Before you put the result on a purchase order

Confirm the construction and weave, nominal geometry, material grade, finished width and length, edge treatment, quantity, tolerance basis and inspection documents. State whether values are nominal, minimum or maximum. For a replacement part, add a drawing or labeled photographs and explain the observed failure mode.

Common mistakes to avoid

Save the input and output with the RFQ so another reviewer can reproduce the calculation. If the duty is critical, use a sample, drawing review or process test before releasing production.
