4 Common Types of Razor Wire You Should Know for Fences

Razor wires are actually steel wires wrapped with steel barbed tapes or ribbons with sharp razors that are spaced at intervals. They are usually installed on the existing metal fences or concrete walls to upgrade the security of the perimeter barriers. There are various types of razor wire available in the market now to meet the needs of different scenarios. Today, we are going to introduce 4 common types of razor wire you should know for fences.

What Are Razor Wires

Razor wires are metal strips with sharp edges that are used to protect boundaries or perimeters by preventing any unauthorized access. They are frequently applied in high-security areas like prisons, nuclear power plants, and military bases.

The production of razor wires requires a few steps and the first is the processing of barbed tapes. Hot-dipped galvanized steel sheets or stainless steel sheets will be punched into barbed tapes with different sizes of sharp blades. Then wrap high-tension galvanized steel wires or stainless steel wires with the stamped blade lath to form razor wires. Different loops of razor wire coils will be buckled according to specific requests. Finally, wrap the finished products with moisture-proof paper and woven bags.

Some razor wires can be used individually as mesh fences to deter intruders, others are usually mounted to the top of fences or concrete walls for added security.

Razor Wire Specifications

Leaving aside various forms of razor wires, they are essentially classified into different specifications mainly based on the blade types. You may see the common blade types listed below.

BTO-10 type: 10mm blade length with 1 mm tolerance, 13mm blade width with 1mm tolerance, 25mm blade spacing with 1 mm tolerance.

For concertina razor wires, more specifications will be sorted according to the outside diameter of the wire coils, loop numbers, and tensile coil length.

No matter whether they are presented in coils or straight wires, razor wires are usually processed with three surface treatments.

  • Type1: pre hot dipped galvanized
  • Type2: pre hot dipped galvanized + polyester powder coated (ral color)
  • Type3: stainless steel surface, including Ss316, Ss304, Ss410

4 Common Types of Razor Wire for Fences

Concertina razor wire

Concertina razor wire, also known as spiral razor wire, is the most commonly used razor wire among the four, covering 80% of the market share. With prominent anti-theft performance, they are usually installed on the walls or existing fences to form medium and high-security fencing boundaries. You may easily notice the usage of concertina razor wires in places like airport grounds, military bases, chemical factories, etc.

Double coil concertina razor wire

The double coil concertina razor wire is an upgrade of the common concertina razor wire. It features a smaller razor wire coil inserted inside a bigger one. This double coil design fulfills the defended areas with dense razor wires, which largely enhances razor wires’ defensive performance.

Many customers prefer this double coil concertina razor wire to the single coil type in pursuit of higher-level security. They are especially popular in projects of prison fencing, military field, national security facilities, etc.

Flat wrap razor wire

Flat wrap razor wire or flat wrap razor coil, is a new type of razor wire fence. Unlike the spiral shape of concertina razor wires, the flat wrap razor wire is constructed by a single strand of razor wire and clipped together loop by loop in a horizontal direction to form a flat sheet.

Made from high-tensile steel wires, flat wrap razor wires are extremely sturdy. And the galvanization surface treatment enables wires resilient to corrosion and oxidation, extending their service life effectively. Plan to upgrade any existing fences or concrete walls to get higher security? The economical but effective flat razor wire is a perfect choice.

Welded razor wire mesh

Finally, we come to the last type of razor wires, the welded razor wire mesh.

Some people may call the welded razor wire mesh diamond razor mesh because the razor wires are welded in form of diamonds or squares. Different from traditional welded wire meshes, the razor wire mesh is flat as a canvas that can be rolled up and stocked easily in the warehouse.

With dense structure and sharp blades, welded razor wire meshes are impossible to climb or enter. It’s quite suitable for high security protection.

Conclusion

Razor wires are widely used in places where high security is needed due to their sharp deterring blades. They may be mounted onto the top of concrete walls or existing metal fences to add extra security or be applied individually in a large boundary area for defense.

The common 4 types of razor wire for fences include concertina razor wires, double coil concertina razor wires, flat wrap razor wires, and welded razor wire mesh. None of them will let you down in terms of providing highly secure protection. But the razor wire prices vary on different specifications.
