Concertina Wire BTO-22 Specification

Release time：2026-03-07    Click：9

　　Concertina wire BTO-22 is a high-security perimeter fencing solution defined by its precise technical specifications, designed for critical applications requiring maximum deterrence against unauthorized entry. Compliant with international security standards, the BTO-22 specification denotes a concertina wire constructed from high-tensile steel strips with a specific blade design: each strip features sharp, serrated edges (typically 22 teeth per linear inch, hence the “22” designation) and is formed into a compact, spiral coil that expands to create a formidable physical barrier. Unlike standard barbed wire or lower-grade razor wire, BTO-22 is engineered for extreme strength and cutting efficiency, making it ideal for prisons, military bases, border crossings, industrial facilities, and other high-security zones.

　　The technical specifications of BTO-22 concertina wire are tailored to deliver uncompromising security performance. The high-tensile steel core ensures the wire resists cutting, bending, and breaking, even when subjected to tools or brute force attempts at breach. The blade design—22 sharp teeth per inch—maximizes deterrence: the serrated edges are heat-treated to maintain sharpness over time, capable of tearing clothing and inflicting significant injury to intruders. The wire is formed into a concertina coil with a specific diameter (typically 450mm to 900mm when expanded) and length (standard rolls of 10m to 50m), allowing for flexible deployment across various perimeter sizes. Additionally, the BTO-22 specification often includes corrosion-resistant treatments, such as hot-dip galvanization or PVC coating, ensuring durability in harsh environments, from coastal salt air to humid tropical regions.

　　Deployment versatility and ease of installation are key features of BTO-22 concertina wire, despite its heavy-duty security capabilities. The wire is supplied in compact, collapsible coils that are easy to transport and handle, even in remote or rugged locations. It can be installed as a standalone barrier (e.g., along fence lines or wall tops) or integrated with existing security infrastructure, such as chain link fences, concrete walls, or steel posts, to create layered protection. Installation typically involves securing the coils to posts using brackets or clips, then expanding them to the desired width to form a continuous, impenetrable barrier. For temporary security needs—such as event security or construction site protection—BTO-22 can be quickly deployed and removed, offering flexibility without compromising safety.

　　Durability and compliance with security standards further reinforce the reliability of BTO-22 concertina wire. The high-tensile steel construction and corrosion-resistant treatments ensure a long service life (typically 15 to 25 years) with minimal maintenance, reducing lifecycle costs for security operators. The wire meets stringent international standards for high-security fencing, including ISO and NATO specifications, guaranteeing consistent quality and performance across batches. Unlike lower-grade razor wire that dulls or rusts quickly, BTO-22 maintains its structural integrity and cutting sharpness over time, ensuring ongoing deterrence against unauthorized entry. For organizations and facilities where security is non-negotiable, BTO-22 concertina wire’s precise specifications and proven performance make it the gold standard in high-security perimeter protection.
