V4A03, HF Shielding Gauze, V4A Stainless Steel, Mesh Width: 0.3mm, 55dB
V4A03 ( former HEG03) is an extremely finely woven, semi-transparent, noncorrosive stainless-steel gauze for the protection against high-frequency radiation (HF) and low-frequency electrical fields (LF).
Typical application due to the thin filaments especially as flyscreen. In comparison 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 vapor, air humidity, mild acids and in coastal areas against salty seawater!

Mesh width: 0.3 mm.
Wire diameter: 0.08 mm
Material thickness: 0.16 mm
Open area: 54 %
Weight: 200 g/m².
Colour: Silver.Fire-proof material, A1 according DIN 4102:1994.Surface conductivity: 0.03 Ohm (square resistance)
In measures of 1.0 running meters. This product is cut off according to your specifications, a return or revocation are not possible.
All shielding attenuation values are valid at 1GHz. Measurement according to ASTM D4935-10 /IEEE Std 299-2006 / IEEEE Std 1128-1998 / ASTM A698/A698M-07.
Electrically conductive. Due to the highly conductive surface this material can be contacted and grounded easily to shield low frequency (LF) electric fields.
please find corresponding components under the category Grounding Accessories. A recommendation here is difficult because this depends on the application.
Floor, ceiling, wall interior, wall exterior
LF (low frequency alternating electrical fields), HF (high frequency electromagnetic radiation)
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 bolt or stapled together. The rule is: Always overlap the single elements at least for 5 cm. For grounding use the perforated stainless steel tape ELB by screwing it right across the elements into the surface.
Please note: The price is valid per m² (square metre), not per running metre!
