Concertina Wire

Concertina wire is a type of barbed wire

Concertina wire packs flat for ease of transport, but can then be deployed as an obstacle much more quickly than ordinary barbed wire.

A platoon of soldiers can deploy a single concertina fence at a rate of about a kilometer per hour. Such an obstacle is not very effective by itself, and concertinas are normally built up into more elaborate patterns as time permits.

Concertina wire is sometimes mistakenly called constantine wire. "Constantine" probably came from a corruption/misunderstanding of "Concertina" and led to confusion with the Roman Emperor Constantine. This in turn has led to some people trying to differentiate between concertina wire and "constantine" wire by incorrectly assigning the latter term to what is commonly known as razor wire. In contrast to the double-helical construction of concertina wire, as shown being deployed by soldiers in the image, razor wire, or less correctly "constantine wire", consists of a single coil of wire with projecting teeth periodically along its length.

Concertina wire is supplied typically in single coils or crossed spiral coils. We can produce razor type barbed wire in concertina coils or straight lines. Blade types and specifications vary according to the customers’ requirements.

Concertina wire (coil) is made by stainless steel sheets and galvanized high tensile claps. It has a beautiful crossing outlook and it is suitable for uses after extending, making an ideal security fencing with great anti-climb and anti-cutting property.
