Concertina wire is a type of razor wire that is formed in large coils that can be expanded like a concertina. It is also called concertina coil, barbed tape concertina, or Constantine wire. Concertina razor wire is fabricated by attaching adjacent loops of helical coils at specified points on the circumference, forming an accordion-like configuration. In this way, there are no gaps of sufficient size for people to squeeze through. It provides unrivaled security and is widely used in applications such as border barriers and military bases.

Heavy-duty clips that bind the razor wire into its shape are the unique feature of concertina wire products, as a weak clip will part, providing easy access for the intruder. These two kinds of clips, however, cannot be parted by hand or ordinary tools. Made of galvanized steel, the clips are weather- and water-resistant, and highly effective and durable.
