Concertina wire, also known as concertina razor wire, is a specialized form of jagged wire crafted from galvanized or stainless steel. It is manufactured in large coils that can be expanded accordion-style, serving as a key element in passive safety measures. The primary purpose of concertina wire is to establish high-security perimeter areas, deterring outsiders from intruding into restricted zones. Widely utilized across industrial, military, and governmental sectors, concertina wire offers versatile installation options due to its spiral design. It can be easily mounted on walls, mesh fences, fence panels, and other vulnerable areas without the need for complex procedures. Engineered with highly resistant blades, concertina wire boasts exceptional penetration capabilities, effectively discouraging potential intruders.
