Steel and Concertina Wire Build Strong Base for Security
The wire is shaped into coils that, when extended, resemble an accordion or concertina, making it versatile for a range of surfaces. By discouraging attempts at climbing or breaching, the sharp barbs create a barrier that is challenging to breach without the use of specialized tools. To improve perimeter security around military stations, jails, detention centers, and high-security facilities, concertina wire is frequently placed on top fences, walls, or other barriers.
