Concertina razor wires or military concertina wires are widely used in various sectors of industrial, governmental, military fields and some security places that need to be protected in our daily life. In this article, you will get plenty of concertina razor wire details like its application, advantages, specifications and well-known manufacturers. Scroll down and read more useful information.
Concertina razor wire is a kind of jagged wire that is produced from galvanized or stainless steel and formed in large coils which can be expanded like a concertina.
The main function of concertina razor wire is to form high-security perimeter areas and prevent any intrusion of outsiders into the restricted areas by the deterrence it produces.
One of the distinguished features of concertina razor wire is its highly resistant blades which have a great capacity for penetration. Concertina wires are usually combined with plain barbed wires and steel pickets to form military wire obstacles. Of course, its application is not limited to military settings.
Besides its application in military field, concertina razor wires are often attached to the top of various metal fences like chain link fencing, high security fences to make deterrent barriers.
You may notice the use of these razor wires in the following areas
Sustainability and Recycling
There will be no bad effect on the environment or any residue work during the whole installation process. The concertina razor wire is removable and recyclable, which means you can disassemble it from the discarded barriers and apply it to a new one.
Deterrence
Concertina razor wires bring severe deterrence to people due to the sharp and dense blades distributed on the wires. This causes effective prevention against any possible intrusions.
Adaptability
Concertina razor wires can be attached to different types of surfaces, such as concrete walls, fences, railings or ground level. That makes it easier to get upgraded security just by combining razor wires with the existing barriers.
Durability
The useful life of the concertina razor wire can reach 10 years if it is galvanized or over 30 years if it is stainless steel concertina razor wire, as it is designed to withstand extreme environmental conditions.
Customization
Normally speaking, concertina razor wires can be customized as per customers’ practical needs in terms of size, the thickness of the blade, colors and materials. You may get more information from the following passages.
The specification of concertina razor coils can be produced according to different projects’ needs. However, you can get the general concertina razor wire specifications from the following table.

According to the material and surface treatment, the concertina razor wires can be divided into three main types, pre hot-dipped galvanized, pre hot-dipped galvanized + polyester powder coated, and stainless steel concertina razor wire.
Generally speaking, the the razor wires produced from stainless steel, which means both blades and core wires are made from stainless steel plate, will provide the best quality. The blades are sharper and sturdier compared with other materials. Of course, its price is also the highest.
If your budget is limited, the medium grade option of stainless steel blade + galvanized steel core wire or economical grade choice of galvanized steel blade + galvanized steel core wire will be suitable for you.
If you prefer colorful razor wires, the pre hot-dipped galvanized + polyester powder coated type will be right for you. The polyester powder coated razor wires are produced with an extra powder coating process to the pre hot-dipped galvanized razor wires.
With the coating treatment, razor wires will be enhanced both in their corrosive resistance and appearance. Normally available powder colors include green, red, and yellow. However, if your projects need other colors to well match the surroundings, just express your requests to the concertina razor wire manufacturers.
Installing concertina razor wire is not difficult, but before that, we need to pay attention to some points so that less time and effort will be taken and no injuries occur during the installation.
Where can I install the razor wires?
The razor wire can be installed on versatile surfaces, you can install it on the ground or on the top of neighbouring posts, on the fence, or against the fence. Each type of installation is different.
What should I take care of for the attachment?
Usually concertina wire is attached every four feet to the adjoining pole and on every foot to the fence. It can be attached with stainless steel rebar ties or with hog rings. Rebar ties generally reduce any vibrations but it does take a little longer to install.
Now comes to the main process of installation. Put on your gloves and follow our instruction step by step.
Step 1
Arrange the coils along the fence line according to the spacing of the coil and the number of coils per roll.
Step 2
Place the coil on its side and then remove the wire ties and discard them.
Step 3
Hold the coil steadily and place it along the length of the fencing line. This is where we begin stretching.
Step 4
Use around six coils and allow them to spring free from the spool which is closest to the starting point. Then these are to be attached to the fence keeping centers of approximately 6 inches.
Step 5
Once the spool has been anchored, take three coils on the other end of the spool. Grasp all three firmly and spread these about one foot from the spool.
Step 6
Grasping all the three spools start stretching the wire.
Step 7
During the pulling process, shake it gently so as to free any snags between any of the coils. It does happen that barb can get entangled. If it happens, then separate by grasping firmly and spreading them apart. Make sure there’s on one around while doing this.
Step 8
When we are pulling the concertina wire along the fence line, there should be another installer to assure the coil spacing consistency by pulling and lifting the materials.
Step 9
We hog ring of the ribbon to the chain link fabric, once the concertina wire is in place. It is possible that we might have to twist the coil so that the ribbon is lined up with the chain link weave.
So the well secured concertina razor wire fence is completed.
