STEEL-GRAY is a compact cotton/polyester/stainless-steel fabric for HF+LF shielding. Typical application as curtain, floor mat, blanket, to incorporate in furniture (beds), room dividers, or with reservations as low priced clothing or bedding.
Important: For clothing the steel threads are not as soft on the skin as of silver fabrics, it feels like a scratchy woolen sweater. Tip: Wear a pyjama in bedding or a sleeping bag made from Steel-Gray, then nothing scratches! Or use it as under-bedding.
- 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
*Note: To purchase a custom length of fabric, please place an order for multiple quantities of the 1ft option. The amount ordered will be cut as a single piece unless specified otherwise.
Order quantity: This product is cut off according to your specifications, a return or revocation is not possible.
Screening attenuation: All stated attenuation values apply at 1 Ghz. Measurement to ASTM D4935-10 or IEEE Std 299-2006 or IEEEE Std 1128-1998 or ASTM A698/A698M-07. You find the test report above under "Report screening attenuation".
Grounding: Electrically conductive. Can be contacted and grounded to shield electric fields (LF). We recommend a plug GP or GD, with a plate GM or GS, plus a cable GC.
Fabric care: Washing at gentle cycle 30°C | Ironing without steam at degree 1 | No drying in tumble dryers | No bleaching | No chemical dry-cleaning | For allergy sufferers: Every new fabric smells, wash before its first usage!
Fabric quality: We only sell top quality fabrics! However, due to the high production costs and in favor of a reasonable retail price, tiny defects (e.g. a flaw in weaving) are no reason for complaint. We appreciate your understanding.
