Originally developed for military purposes, concertina razor wire has evolved into a versatile and effective tool used for a wide range of security applications, from border control to residential and commercial protection. In this guide, we’ll take a closer look at its design, history, applications, benefits, and some of the challenges you might face when using it, so you can understand why it’s the preferred choice for perimeter security across the globe.
What is Concertina Razor Wire?
Concertina razor wire is a type of high-security fencing made from long strips of sharp blades, designed to cause serious injury to anyone attempting to breach the barrier. Typically made of galvanized steel, the wire is coiled like a spring to create concertina loops. When stretched out, these loops expand to form a continuous and highly effective barrier that is very hard to climb or cut through. The combination of barbs and razor-sharp blades is specifically designed to physically impede intruders and deter unauthorized access.
This range of blade types is ideal for use in security fencing systems, designed to meet various levels of threat prevention and aesthetic requirements.

Compared to traditional barbed wire, which only relies on sharp points, concertina razor wire features much sharper blades that can cause deep cuts and lacerations, making it a significantly more formidable obstacle.
The roots of concertina razor wire go back to the late 19th century, when barbed wire became a widely used tool in agriculture and military defense. Barbed wire saw extensive use during World War I, particularly in trench warfare, where it was used to slow enemy advances. Despite its utility, barbed wire had certain limitations in its ability to provide an impenetrable defense.
Concertina wire, named after the concertina musical instrument due to its coiled, collapsible structure, emerged as an enhanced version of barbed wire. During the Cold War, the use of concertina razor wire became prominent, especially in high-security installations, border areas, and military zones. The addition of razor-like blades made it highly effective in preventing intrusion, quickly becoming a favorite for governments and organizations concerned with high security.
Structure and Components
Concertina razor wire consists of several components that contribute to its effectiveness:
- Galvanized Core Wire: The central wire is made of galvanized steel, providing core strength and flexibility. The galvanization process helps protect the wire from rust and corrosion, ensuring it can withstand harsh environmental conditions.
- Razor-Sharp Blades: The defining feature of concertina razor wire is the series of sharp blades. These blades are stamped from steel strips and are wrapped around the core wire at consistent intervals. They are designed to deter intruders both visually and physically, with a cutting edge that can easily inflict significant injury.
- Clips and Fasteners: Clips are used to link multiple coils together, increasing the density and complexity of the barrier. These clips also add stability, making it more challenging for intruders to manipulate or breach the wire.
The combination of these elements makes concertina razor wire an imposing security measure that can be customized to meet specific requirements. It is available in different coil diameters, with varying blade spacing, to suit different levels of security.
- Blade Type: Each type, from BTO10 to CBT65, varies in structure and cutting profile, offering diverse levels of deterrence and protection.
- Blade Shape: The table displays distinct shapes for each blade type, with each configuration designed to enhance security. These shapes are optimized to maximize the deterrent effect against intrusions.
- Blade Thickness: The blades have thickness variations with two primary specifications:
- 0.50 ± 0.05 mm: Used in blade types BTO10 through BTO30.
- 0.60 ± 0.05 mm: Applied in larger blades, CBT60 and CBT65, for added durability.
- Core Wire: The core wire has a diameter of 2.50 ± 0.10 mm, ensuring structural integrity across all blade types.
- Blade Length, Width, and Space:
- Blade Length: Ranges from 10 mm for BTO10 to 65 mm for CBT65, adapting to different security intensities.
- Blade Width: From 13 mm to 32 mm, the width influences the blade’s visual and physical impact.
- Blade Space: The spacing between blades varies, from 26 mm in BTO10 to 100 mm in CBT65, balancing deterrence and material coverage.
