Razor wire, also referred to as concertina wire, is a type of security fencing material that is extensively used in commercial and industrial settings. It has sharp edges or pointed spikes that are designed to deter intruders from climbing over the fence. The high-tensile steel wire used to manufacture razor wire is produced by stamping out blades and then coiling them around two or more high-tensile wires.

This makes the material highly resilient and durable, ensuring that it can withstand harsh weather conditions without losing its effectiveness. Additionally, razor wire is easy to install and relatively low cost compared to other security fencing materials.

As such, it’s often chosen as a practical measure for securing sensitive areas like prisons, military bases, factories, and warehouses against unauthorized entry.
