As we know, Concertina Razor Wire has two formations: spiral formation (unclipped) and concertina formation (clipped).
 
We manufacture razor wire in concertina coils or straight razor lines. Concertina coils include single, double, and across spiral shaped coils. It is made of galvanized barbed tape and high tensile galvanized core wire, which form continuous spiral razor wire. We use galvanized materials to prevent corrosion. And all materials have been strict quality tested to ensure razor concertina products strength and efficiency. The coils can be collapsable for easy transportation, and can be easily retracted and stored vertically or horizontally.


Each spiral circle is joined by three, five or seven rows of connector clips, depending on the diameter of the circle. This condenses the spacing of the spirals.  The clip is made of 1.5-2mm thick and overall 10mm wide hot – galvanized sheet metal or stainless steel. This makes the coil very difficult to open, even with a special tool. The diameter of the circle is reduced by 5-10% after opening.
 
Concertina coils are usually installed on the top of chain link fence, welded wire fence or walls, on the ground or at the bottom of fencing. It forms an uncrossable barrier called concertina coil fencing. Often a line of barbed wire runs across the concertina coil fencing. This type fence is ideal security fencing with great anti-climb and anti-cutting property, and has very high security, strong and durable features. It is widely use in garden, school, prison, military sites and airport for effectively protecting these areas from external invasion threats.
