YSHIELD® STEEL-TWIN | Shielding fabric | Width 150 cm | 1 meter

Properties

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

Shielding attenuation HF & LF

This product shields high frequency electromagnetic fields (HF). Unless otherwise stated, the indicated dB-values apply to 1 GHz. Measurement from 600 MHz to 40 GHz according to standards ASTM D4935-10 or IEEE Std 299-2006.

This product with an electrically conductive surface shields low-frequency alternating electric fields (LF).

Laboratory & expert report of shielding attenuation up to 40 GHz

We have already invested in our own professional EMV laboratory years ago. We not only use it to create our laboratory screening reports but also to check each batch daily. Additionally, we have all our products checked by an independent, well-respected expert. Double checked for twice the safety. Please find the reports above at the downloads.

Ready for 5G

Some companies offer "special" 5G-products. This products shields all 5G-frequencies, even without advertising this! Find two gray bars in all shielding diagrams with the 5G frequency spectrums FR1 (600 MHz – 6GHz) and FR2 (24 GHz – 40 GHz).
