The success of razor wire lies in the longer length of its spear-like barbs, difficulty of gaining a handhold, and the strength of the steel tape. Razor wire works to impede entry by either catching clothing or ripping through flesh.

Razor wire is one of the most common and widely used high security fencing products; it represents the ultimate evolution of barbed wire and provides a very effective low-cost deterrent against unwanted intrusion and vandalism.

Concertina razor wire, as the name suggests, consists of linked loops of steel razor tape reinforced with high tensile wire forming a concertina pattern somewhat similar to a stretched spring.

Concertina razor wire is intended for high security applications including:

• Prisons
• Military installations
• Electrical substations or high voltage pylons
• Railway yards
• Airports
• Factories and warehouses
• Hazardous chemical plants or storage areas
