    Steel-Twin, RF Shielding Fabric, 35dB

    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 grey 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
