Metal Strips

Metal Strips is a rigid EMI aluminum strip with a wire mesh and or elastomer gasket secured into the groove of the extrusion. Wire-Knit gaskets are supplied in standard wire alloys in several configurations and size to meet specific shielding requirements. Wire-Knit Elastomer Core gaskets may be applied for environmental pressure sealing. Wire-Knit or Elastomer Core gaskets may be applied in any combination to one or both sides of the strip.  Metal strips are fabricated with specific hole size, location, slots and countersinks for alignment. Ready-to-mount strips are attached with rivets, fasteners or spot welded to flange surfaces. Lengths range from two inches to eight foot lengths and come in multiple profiles. Strips are supplied unfinished or Chromate Coated per MIL-DTL-5541 Class 1or 3 to enhance shielding performance and corrosion resistance. Metal Strips add structural strength to enclosures and perform as a positive compression stop where a rigid gasket is required.
