Razor Fence / Concertina coil

Concertina Fencing is a security fencing solution that incorporates Concertina Coils into a framework to create a robust and effective barrier.

It combines the features of traditional fencing with the enhanced security provided by razor wire coils.


  • High-Security Areas: Ideal for securing high-security zones such as military bases, prisons, and government facilities.
  • Perimeter Security: Provides an effective perimeter barrier for commercial and industrial properties.
  • Border Control: Used along national borders to prevent unauthorized access.


  • Framework: Typically made of galvanized steel or other durable materials.
  • Concertina Coils: Razor-sharp blades integrated into the fencing for added security.
  • Height Options: Available in various heights to suit different security requirements.
  • Customization: Can be customized for specific applications and security levels.
  • Anti-Climb Design: Deters intruders from attempting to climb over the fence.

Razor wire fence installation

Razor wire or Barbed tapes are metal striped mesh fences used for high-level security. The tips are sharp in a way to rip the clothes and flesh of trespassers who try to make suspicious entries. Multiple blade-type clips are attached to the coils that form the Concertina Coils. Usually, these fences are coupled with other wire mesh or chain link fences to achieve high-level security. It is widely used in prison fencing, airport fencing, highway fencing, and many more where top-level security has to be achieved.

Some of the features of the Razor wire fences are:
  • Installation and uninstallation are convenient and easy.
  • Can be combined with other fence types to provide maximum security
  • Resistant towards corrosion and rust.
  • Sharp edges to keep intruders and trespassers away
  • Available in multiple colors
  • Military units
  • Hospitals
  • Manufacturing units
  • Warehouses
  • Oil and gas stations
  • Airports
  • Prisons

Galvanized zinc is the main quality of these razor wire fences. The thickness of the zinc used is the main quality criterion, and it decides the life of the fence. The thicker the fence, the better it stands against corrosion.The mechanical properties such as elasticity, strength, and hardness of this fence make it impossible to cut or get through the fence without any special tools and the zinc layer in addition will make the fence stand still at least for 25 years. Razor wire concertina is mostly used as a mobile security barrier to enclose or protect an area.

Types of Razor Wire Fences

The razor concertina coils can be flat or coiled, further classifying it can be single coiled or double-coiled.

  • Single Coil Razor Wires: Hot dipped galvanized steel plates with processed razor wire coils are extended in spiral types
  • Large coils Crossed: Razor wires with Crossed spirals are clipped together to form the large coils
  • Y Post Supported Wire fences: Wire fences are mounted on top of a Y post fence.
  • Electrified Wire fence: Copper wires are placed inside the core of razor blades. This electrifies the fence and enhances security.

Step 1:

Razor wire fences can be assembled directly on the ground. In the absence of any other fence types or other structures, razor fences can be mounted directly on the razor wire surface using light gauges and special brackets. For additional safety, it might be sufficient to establish a large-diameter spiral razor mesh which will create a formidable obstacle for an intruder to get through.
Just in case you wish to heighten the security level, razor barbed wire is mounted along the ground. These are arranged in pyramid patterns.

The razor wire fence can also arrange in a spiral pattern and following the same pattern for several rows. We mount the spiral patterns over metal supports such as U-shaped, V-shaped cross-shaped, and brackets.


Step 2:

The razor wire fence is set up as a safety barrier and can be built of varying height, width, and thickness, on any type of fence, both directly on the ground, over walls, and on roofs.

In residential areas, the installation is carried out in three stages:

  1. First, the bearing is secured on the fence. Then the wire is stretched
  2. Spirals are laid to form the cradles
  3. Concertina Consolidation


Step 3:

Adding additional security can be done through concertina wire barriers. They can be installed over the ground or can be installed over an existing fence. Since these razor wires are sharp, without proper tools it is difficult to install these fences. Hence special attention is required during installation. So to avoid accidents or minor cuts during installation, and also to obtain maximum security, high-quality, reliable, and durable fences we recommend installation or repair only through trusted service products and service providers like us.
