Shielding fabric ST-Steel Twin

BRAND: Gigahertz Solutions

STEEL-TWIN is a compact cotton/stainless steel fabric for the protection against high-frequency (HF) radiation. Typical application as curtain.

Special feature: The frontside is made of white cotton, while the backside is densely woven with a stainless steel thread. Despite the high attenuation due to the gray stainless steel threads on the backside, this fabric has a light gray front side!

Good screening attenuation, even at high frequencies! →Excellent cost/performance ratio →Contactable
(groundable) to shield LF electric fields → Textile characteristics: Washable, easy to iron and process
Quality grade: Very high
Width: 150 cm, +/- 2 cm   Length: Available by the meter
Attenuation: 35 dB at 1 GHz  Color: Frontside light gray, backside silver
Raw materials: 68 % cotton, 16 % polyester, 16 % stainless steel  Weight: 190 g/m²
Dimension stability: +/- 3 %  Surface conductivity: 100-800 ohm / inch (2.54 cm)

Due to the surface conductivity this fabric can be grounded to shield low frequency (LF) electric fields. For professional grounding we recommend our Grounding-Plug EST.

The shielding attenuation is regularly tested in our own laboratory or by Professor Dipl.Ing. Pauli at the University of the German Federal Armed Forces in Munich due to the standards ASTM D4935-10 and/or IEEE-STD-299-2006. The line in the diagram stands for the radial direction of polarization (both directions, horizontal/vertical) and indicates the attenuation achievable in practice.
