EMI / RFI Shielding Mesh for attenuating electromagnetic and radio-frequency interference through vents, windows and enclosures while still passing air and light. 5 sizes listed, with technical drawing and quotation.
Customize the parameters below — every spec field is editable, and the drawing redraws to match the values you choose. Changing the size will snap the other fields to that size's standard values; you can then override any individual value.

EMI / RFI Shielding Mesh (MIL-DTL-83528 / IEEE 299) is used for attenuating electromagnetic and radio-frequency interference through vents, windows and enclosures while still passing air and light.
Also known as: emi shielding mesh, RF shielding mesh, metal mesh EMI shield, wire mesh for enclosures
Frequency range: Finer mesh and thicker wire raise attenuation at higher frequencies; state the band to be shielded.
Conductivity & corrosion: Copper and phosphor bronze conduct best; Monel 400 and stainless resist corrosion in marine or outdoor use.
Bonding: Specify a continuous, low-resistance perimeter bond — the mesh only works when grounded all round.
Materials
Standard supply is copper, Monel 400, stainless steel 304; the material column in the table and the drawing options show the exact grade for each size. Other alloys and finishes can be quoted to your drawing.
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.
Common Mistakes
Leaving gaps or spot fixings along the edge, which act as slot antennas and leak RF.
Pairing copper mesh with an aluminum frame without plating, which corrodes galvanically.
When EMI / RFI Shielding Mesh Is Not the Right Choice
Not a fire, thermal or ballistic barrier — combine with other materials where those properties are needed.
EMI / RFI Shielding Mesh is stocked and supplied to order in rolls, cut sheets and fabricated pieces. Pricing starts from approximately US$6.50 per unit for standard specifications in stainless steel 304; final pricing depends on specification, alloy, quantity and fabrication (MOQ applies).

Attenuating electromagnetic and radio-frequency interference through vents, windows and enclosures while still passing air and light.
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.
Why must shielding mesh be grounded?
Currents induced in the mesh must flow to ground; an ungrounded mesh re-radiates instead of shielding.
Which specifications of EMI / RFI Shielding Mesh does custommetalfilters.com supply?
The table on this page lists 5 standard specifications for EMI / RFI Shielding Mesh, from 22-Mesh to 145-Mesh. Specifications outside the table — custom mesh counts, wire diameters, roll widths and fabricated pieces — can be quoted on request.
