A type of barbed wire, formed into large coils which can be expanded like a concertina (a musical instrument), is frequently utilized as a physical security barrier. The sharp edges and points of the wire are designed to inflict pain and deter unauthorized access across a perimeter. Often constructed from galvanized steel to resist corrosion, this barrier is deployed rapidly and efficiently in situations requiring enhanced security.
Its deployment provides a significant deterrent against intrusion and unauthorized movement. Historically, this type of barrier has been used in military applications, prison security, and border control. The relative ease of deployment and effectiveness in preventing passage makes it a cost-effective solution for securing vulnerable areas and managing access to restricted zones. Its presence serves as a visual and physical obstacle, increasing the time and effort required for any breach.
