What is concertina wire

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 (a small hand-held bellows-type instrument in the same family as the accordion). In conjunction with plain barbed wire (and/or razor wire/tape) and steel pickets, it is most often used to form military-style wire obstacles. It is also used in non-military settings, such as when used in prison barriers, detention camps, riot control, or at international borders. During World War I, soldiers manufactured concertina wire themselves, using ordinary barbed wire. Today, it is factory made.

Concertina wire is formed in large coils which can be stretched like a concertina. Rigid and sharp blade frightens or hurt any person or animal that want to go through concertina wire fence.

Concertina razor wire is available in galvanized, PVC coated and stainless steel wire materials. Broadly speaking, galvanized razor wire is very effective and relatively cheap.

Concertina wire is supplied in single coils, double coils or crossed spiral coils. Besides coiled concertina wire, straight razor wire is also provided, which can be welded to fences.

Applications: Fencing enhancement, wall enhancement, border security, military base security.
