Concertina razor wire is the next level up in security from commercial helical razor wire. it is made of stainless steelor galvanized sheets and high tensile claps. Rather than a single helical spiral of razor wire, adjacent loops of concertina razor wire is clips at 3 points around the circumference of the razor wire. This turns the razor wire into a diamond shaped maze, creating a much denser and more secure barrier. It is used for industrial security, minimum to medium security jails and prisons. On the part of the packing terms, it is packaged in coils of various diameters.

The blade types and specifications can be tailored according to the customers' actual requirements. BTO-10 and BTO-22 are normally used in production of cross type.

The special concertina security barrier can be installed as bellow:

On-the ground installation: special security barriers can be mounted vertically or horizontally in one, two, or three rows, anchored to the ground and fastened together with tie wire.

On top of the existing perimeter (fence, etc): the security barrier is fastened with metal brackets.

Complex installation (on top of the existing fence and on the ground inside the perimeter): to ensure strong fixation, the barrier can be air-gunned to the reinforced concrete wall with metal straps.
