V4A03 stainless steel mesh being worked into the render

Shielding stainless steel gauze (mesh) V4A03 for flexible application inside and outside. The shielding fabric is corrosion resistant and insensitive to heat. With this shielding fabric against electrosmog HF + LF the highly effective radiation protection against electrosmog is possible. Shielding efficiency 99.999% (55dB). Width 90cm. Effective against 5G!

This V4A03 stainless steel mesh is an extremely-finely woven and corrosion-resistant stainless steel mesh. It can be effectively installed to shield against electrosmog from radio (HF) and alternating fields from the power supply, for example (LF).

Compared to the V4A10 stainless steel mesh, the attenuation drops less drastically at higher frequencies from 2.4 GHz. This impressive result is possible thanks to V4A03’s considerably lower mesh size. TheV4A03 stainless steel mesh is considered to be a base shielding mesh. Both layers of EMF shielding have their own uses, it depends on where you use it.

The shielding V4A03 stainless steel mesh also impresses with its resistance to corrosion. It is simply great in house construction for shielding the entire building, even near the coast and salt water. Importantly, the V4A03 stainless steel mesh is very resistant to water, steam, humidity, weak acids and salty seawater on the coast.

Typical use of the V4A03 stainless steel gauze

Inside and outside under the render in insulation, in the ceiling, in timber construction, dry construction, loose laying, and many more. Like the V4A10, the V4A03 stainless steel mesh is a suitable fly screen against mosquitoes among others with its 0.3 mm mesh.

Processing the V4A03 stainless steel mesh against electrosmog

When working under a render, this V4A03 stainless steel mesh should be stuck with the finest organic filler (without fillings) possible. When working under flooring (laminate, parquet, PVC, etc.), V4A03 is stuck on with the adhesive. In dry construction and ceilings, the tracks fasten or can be stuck on as required. The following always applies: the tracks overlap for 5 cm. For grounding, our stainless steel tape is put on across all of the tracks and stuck to the substrate/tracks.

Order quantity, revocation of the order and small quantity surcharge

If the fleece has been cut in pieces of 1.0 running meter as requested by the customer, it is not possible to cancel or revoke the order. For this reason, it is possible to request a free sample of the shielding fleece. By ordering pre-finished products, waiving the statutory right to return goods is accepted.

Daily business has shown that small quantities can not be financed by the continuously rising costs of packaging and shipping. Therefore, we are forced to introduce a minimum quantity surcharge for small quantities of up to 3 meters with this product. We ask for your understanding.
