Concertina wire, also called Dannert Wire , is a type of barbed wire or razor wire that is formed in large coils which can be expanded like a concertina. Zheng Yang concertina 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 application.

Concertina Razor Wire has two structures: spiral formation and concertina formation . Each spiral circle is joined by three, five or seven rows of connector clips, depending on the diameter of the circle. This condenses the spacing of the spirals. The clip is made of 1.5-2mm thick and overall 10mm wide hot – galvanized sheet metal or stainless steel. This makes the coil very difficult to open, even with a special tool. The diameter of the circle is reduced by 5-10% after opening.  In conjunction with plain barbed wire and steel pickets, it is used to form military wire obstacles, government facilities, prison, military zones, airport, farm, police, private security zones, border security, private properties cannot be without it.
