22 mesh emi / rfi shielding mesh has 22 openings per linear inch. Woven to MIL-DTL-83528 / IEEE 299, this page lists the controlling specification — wire diameter, aperture, micron rating, open area and cloth weight — together with the wire options available at this count and the duties it is normally specified for.

Typical Applications for 22 Mesh EMI / RFI Shielding Mesh

22 mesh emi / rfi shielding mesh is commonly specified for general straining and sieving, paint and coating filtration, grease filters, insect screening, grain cleaning and pre-filtration ahead of fine media.

What EMI / RFI Shielding Mesh Does

Attenuating electromagnetic and radio-frequency interference through vents, windows and enclosures while still passing air and light.

Fitting & Care

  • Clamp the mesh edges under a conductive gasket or solder them continuously to the frame.
  • Keep paint and anodizing off contact faces; mask them before finishing.

Frequently Asked Questions

Which mesh is best for EMI shielding?

Copper or phosphor bronze in 60–100 mesh is common; Monel or stainless are chosen where corrosion is a concern.

How much shielding does woven mesh give?

Typically 50–75 dB around 1 GHz, depending on mesh count, wire and the quality of the edge bond.
