Spiral Razor Wire
Concertina wire is a type of razor wire, also commonly called concertina wire coil. Hexagonal barbed wire is produced by connecting adjacent helical coil loops to each other at designated points on the circumference to form an accordion-like structure. In this way, there is no gap large enough for people to squeeze through. It provides unmatched security and is widely used in applications such as border barriers and military bases.
The heavy-duty clips that hold the razor wire into its shape are a unique feature of concertina wire products, these clips are made of galvanized steel, are weather and water resistant, and are very effective and durable. This heavy-duty clip cannot be separated by hand or ordinary tools. So concertina wire is called high security blade razor wire.
