Stainless Steel Gauze-V4A03/HF+LF Shielding

Due to the thin filaments, use as flyscreen or net curtain, etc

V4A03 is an extremely fine woven, noncorrosive stainless-steel gauze for the protection against high-frequency radiation (HF) and low-frequency electric fields (LF).

In comparision to V4A10, due to the smaller mesh width, the shielding attenuation is better at high frequencies.
Further application in roof areas, at drywall constructions, loosely laid, etc.

V4A (AISI 316) is resistant against water, water vapour, air humidity, mild acids and in coastal areas against salty seawater!

In case processing as flyscreen, the application is identical to that of a regular flyscreen in commercial tenter frames.
In case processing the V4A03 under plaster you should work with a finest organic filler. Under the floor covering (laminate, parquet, PVC coating, etc.) the V4A03 is being fixed with the adhesive used for the floor covering.
For drywall construction and in roof area the mesh elements can be bolted or stapled together.
The rule is: Always overlapp the single elements by at least 5 cm.
For grounding use the perforated stainless steel tape ELB by screwing it right across the elements into the surface.

Due to the highly conductive surface this material can be contacted and grounded easy to shield low frequency (LF) electric fields.
For professional grounding we recommend our Grounding Plate Magnet - GM, in combination with Grounding Cable GC-200 Plugged into Grounding Plate Tube-GT/Attach to copper heating Pipes for loose laying application, or our perforated Stainless Steel Tape ELB for application under-plaster or in drywall constructions.

Shielding attenuation
The indicated dB-values apply to 1 GHz. Measurement from 40/600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006,. You'll find the PDF test report with further details above on this page.
