Concertina barbed tapes

Razor tape concertina tape, often referred to as razor wire is the modern version of barbed wire, designed to prevent intrusion along perimeter barriers. Razor wire is fabricated from high tensile wire (virtually impossible to cut with standard hand tools) onto which a multitude of razor-sharp barbs are formed at close intervals. The barbs are designed to have a piercing and gripping action. The wire and strip are galvanized to prevent corrosion.
