Concertina wire or Dannert Wire is a type of barbed wire or razor wire that is formed in large coils which can be expanded like a concertina. In conjunction with plain barbed wire and steel pickets, it is used to form military wire obstacles. Our concertina spiral razor wire is made of 0.5mm thick hot-galvanized steel sheet and 2.5mm thick high-carbon galvanized wire. These coils are compressed for transportation, and then stretched for use.
