Stainless steel mesh from corrosion-resistant V4A as with maximum shielding for drywall constructions or as flyscreen. 50 dB. Interior and exterior. Width 90 cm. 



V4A03 is an extremely fine woven, noncorrosive stainless-steel gauze for the protection against high-frequency radiation (HF) and low-frequency electric fields (LF). V4A (AISI 316) is resistant against water, water vapor, air humidity, mild acids and in coastal areas against salty seawater!


Due to the thin filaments the typical application is as flyscreen. 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 constructionsloosely laid, etc.


When used as flyscreen, the application is identical to that of a regular flyscreen in commercial tenter frames. When using V4A03 under plaster you should work with the finest organic filler. When used under the floor covering (laminate, parquet, PVC coating, etc.) the V4A03 should be 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 overlap the single elements at least 5 cm. For grounding use the perforated stainless steel tape ELB by screwing it right across the elements into the surface.

Attenuation | Grounding

  • This product shields high frequency electromagnetic fields (HF). The indicated dB-values apply to 1 GHz, view chart for other frequencies. Expert reports ranging from 40/600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006, view report below.
  • This product with an electrically conductive surface shields low-frequency alternating electric fields (LF). For this purpose a grounding is necessary, i.e. an integration into the functional-equipotential bonding (FEB). Please find suitable grounding accessories in our shop.
  • All grounding must be done by a licensed electrician.
