EMC test labs: shielded rooms, test cages and anechoic chamber linings.
Data security: shielded server rooms, SCIFs and secure meeting rooms.
EMP & prepper protection: Faraday boxes and cabinets for spare electronics and radios.
Research & medical: RF-quiet enclosures for sensitive measurements and EEG rooms.

How to Specify Faraday Cage Shielding Mesh

Mesh count & material: Copper 16–60 mesh gives the best attenuation per weight; galvanized steel mesh is cheaper and also shields magnetic fields at low frequency.
Opening vs frequency: Holes must be much smaller than the wavelength — finer mesh for higher frequencies (Wi-Fi, 5G).
Seams & grounding: Overlap seams by at least 50 mm, bond them continuously and ground the cage at a single point.

Materials

Standard supply is copper, 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

Solder or clamp every seam continuously; spot fixings leave slot-shaped leaks.
Seal doors and lids with conductive finger stock or gasket, and filter any cable that enters.

Common Mistakes

Unbonded seams or doors, which leak far more RF than the mesh itself.
Running unfiltered power or data cables through the cage wall, which carries RF straight in.

When Faraday Cage Shielding Mesh Is Not the Right Choice

Not a lightning-protection system, and a mesh cage alone does not stop very low-frequency magnetic fields — those need solid steel or mu-metal shielding.

Frequently Asked Questions

What is Faraday Cage Shielding Mesh used for?

Building Faraday cages, RF-shielded rooms and EMP-protected enclosures from conductive woven metal mesh that blocks external radio-frequency fields while staying light, ventilated and see-through.

What is the best metal mesh for a Faraday cage?

Copper woven mesh around 16–60 mesh; galvanized steel mesh is a cheaper alternative.

Does the mesh hole size matter for a Faraday cage?

Yes — openings must be much smaller than the wavelength being blocked, so higher frequencies need finer mesh.

Copper or galvanized Faraday cage mesh?

Copper shields better and is easier to solder; galvanized steel is stronger and cheaper.
