Concertina Razor Wire, or Barbed Tape Concertina, is the galvanized Barbed Tape combined with the core wire, to form continuous spirals which are clipped together at various intervals with heavy duty clips. These coils are collapsable for transportation, and then expanded and fastened for use.

The Strength of the product is in the heavy duty clip, which is used for the shaping of the concertina coil. This heavy duty clip (Figure 2) is manufactured to have a thickness of 1.6mm and an overall width of 10mm, and is available in either galvanized or stainless steel. This clip, once fastened to the razor wire, requires a force of approximately 1000 newtons before showing signs of opening, making it very difficult to remove, even with specialized tools.
