Concertina Razor Coils, also known as "Snake Belly" or "Blade Coil", is a type of barbed wire that features sharp, serrated blades attached to a core wire. This security fencing material is widely used for high-security applications due to its effectiveness in deterring unauthorized access.

The product's advantages include its high level of security, as the razor-sharp blades can cause serious injury to anyone attempting to climb or cut through the fence. It is also highly visible, which acts as a deterrent to potential intruders. Additionally, the concertina razor coils are resistant to corrosion and weathering, ensuring long-lasting protection.

The concertina razor coils can be used in various applications, such as border security, military installations, prisons, and high-security facilities. They can be installed on top of existing fences or walls to enhance security or used as a standalone barrier.

The dimensions of the concertina razor coils can vary depending on the specific requirements. Common sizes include 20 meters per roll, with a core wire diameter of 2.5mm and a blade length of 22mm. The spacing between the coils can also be adjusted to suit different security needs.

Installation of the concertina razor coils typically involves attaching them to a fence or wall using clips or brackets. The coils can be easily unrolled and secured in place, providing a quick and effective security solution. Proper safety precautions should be taken during installation to avoid injury from the sharp blades.
