Concertina Wire
Concertina wire or razor wire is a type of fencing that is razor-sharp and can be rolled up to fit into a small bag. Concertina wire is made from galvanized steel. It is a very durable material that can last for years. It is available in many different sizes and types.
Concertina wire was invented and commonly used by the military to discourage passage. It has found use in civilian law enforcement, in perimeters and barricades to deter illegal immigration, and in crowd control barriers.
And it is sometimes used to protect vehicles and equipment. Concertina wire is a wire obstacle made up of a row of steel blades or “fins” laid at intervals along a wire. It is used to create a continuous barrier that can restrict passage. Impede the progress of an advancing enemy, or be rapidly deployable by engineers.
In the past, barbed wire was the most common form of protection for military fortifications but it was quickly replaced by “razor wire”. Concertina wire was developed in Germany in the mid-19th century. And was named for its resemblance to the concertina accordion.
Concertina wire, also known as “coiled wire” or “concertina coil”. It is a type of barbed wire or razor wire that is folded in on itself to create a continuous fence or barrier. The concertina wire is then wrapped around itself, with the coils typically being linked by short lengths of pickets.
Concertina wire is commonly used to create barriers that are difficult to breach. The coils can either be electrically charged to deliver a shock to those who touch it. Or it may be flanked by a more traditional barbed wire fence to create a more severe abrasion on the intruder.
Here’s an overview of the different types of concertina wire:
- Concertina wire fence
- Concertina razor wire
- Razor wire fence
- Razor barbed wire
- Military concertina wire
Security Barriers
Security barriers are certainly one of the best physical obstacles to have in place. The barrier is made from galvanized steel – typically. Having a stripe or gauze thickness of 0.55 mm to 1.5 mm. And is reinforced with 2.8mm by 3mm high carbon galvanized wire (depending on what’s needed).
These barriers have double-edged, unambiguous spines that are, again, spaced evenly all the way around. And work to deter would-be trespassers and intruders from where they shouldn’t be at any given moment.
Depending on your budget, you can choose whatever width works best for you between 450 mm, 500 mm, 600 mm, 730 mm and even 900 mm which will allow more “give” in case someone were to tamper with it not knowing that it’s capable of being stretched. Now truly this is the ultimate security barrier – durable and strong enough not to break under pressure while perfectly functional at keeping an area safe & secure!
Concertina razor wire
Concertina razor wire is an intimidating barricade that is an efficient way to secure fencing without building a physical perimeter or covering it with netting. Concertina razor wire is made from ordinary razor wire that is coiled and connected into a cylindrical shape.
This configuration allows people to walk through it without getting caught. When people or animals try to push through the razor wire, but, the barrels will become tangled and difficult to move.
Concertina razor wire can be used to protect perimeters. But it’s particularly popular in prisons where it is used to deter violent behavior.
Concertina razor wire is extremely sharp and can cause deep cuts. Though it’s usually retrieved with pliers or a wire cutter before anyone gets harmed.
Razor wire fence
Razor wire is used as a security measure to prevent intruders from entering. It is generally a coiled wire with sharp edges that is placed around restricted areas like military installations or prisons.
The sharp wire makes it difficult for a person to climb over or cut through. It can also be used in concert with other barriers, such as barbed wire. Or in a line to prevent vehicular entry to a certain area.
Razor barbed wire
Razor barb wire is a type of wire that has had razor blades drilled into it. It is primarily used as a visual deterrent and only as an ultimum remedium against intruders.
The razor blades are very sharp. And when sliced against the skin will result in deep cuts that may need stitches.
They are primarily used to keep people from entering private property. And are a controversial means of keeping trespassers off land that is owned or leased.
Difference between barbed wire and razor wire
Razor wire has fine, sharp points that are good at preventing an intruder from getting through it. They’re usually packed closely together, which makes it harder to get over or through.
It’s commonly used for security in prisons and other places where protection is needed. So, barbed wire is thick and has points that aren’t sharp enough to pierce anything.
It’s used to keep animals from getting onto a property. It would be impossible for a person to get through barbed wire.
The big difference between the two is the size of the wire. Razor wire is thinner, so it’s harder to get through. Barbed wire is thick, so it doesn’t let anything in.
Military concertina wire
Concertina wire (or razor wire) is a type of fencing that is often used for military purposes. Concertina wire is made of a row of sharp, scalloped steel blades that interlock to form a fence or wall.
Concertina wire is different from barbed wire. Because the steel blades are exposed rather than hidden beneath another material.
Concertina wire is often used to surround military bases. Each strand of concertina wire is made of many wires that are twisted together to form a single, continuous strand. Concertina wire is also more effective than barbed wire and other fencing at keeping animals out of certain areas.
How long does concertina wire lasts
Concertina wire has a very long lifespan. It is coated with a thick layer of vinyl and plastic to protect against the elements. It can last for over 20 years before requiring a repair.
Concertina wire is also used for many types of home and commercial fences. As a way to keep intruders out without compromising on aesthetics of the surrounding area.

Strength of concertina wire
The strength of concertina really depends on the wire itself. Generally, concertina wire is made with 2 layers of steel. Which means it is much stronger than other types of wire. Some concertina is made with galvanized steel, which means it is extra strong.
Concertina wire can usually survive many years in harsh conditions without any damage or deterioration. It is a very durable wire. Although it’s difficult to determine which concertina wire is the strongest. You’ll want to make sure that it is at least a 2-layer wire if you want it to be extra strong.

Workshop show
We have our own factory and specialized razor wire workshop. Tens of machines are working all the day for the goods delivered to the whole world. The below is the introduction of our machines and raw materials in our workshop.
Punching machine.
It is used to cut the galvanized iron sheet to different razors. This is realized by kinds of mould.
Main processing machine.
This is used to combine the iron wires and finished galvanized razors together by pressing. This is the major step in production.
Pressing machine
After goods are finished, this machine will be used to press the razor wire coils to lower their volume. This step is applied for most razor wire types to make the freight cost-effective. But for some types, like the CBT-65, this will damage their structure to some extent and affect their normal function.
Raw material
There are two kinds of materials needed for this item: steel inner wire and galvanized iron sheet. The iron sheet will be cut to different shapes to meet different needs. And the steel wire will be used as the inner wire to make ti more strong and hard to break.

Uses of concertina wire
Concertina wire has many uses, including keeping people in and animals out of an area. Concertina wire is also used in other areas, such as keeping criminals in jail.
Concertina wire is commonly used in military bases, prisons and other institutions where high security is needed. Concertina wire can be used to block off perimeters of private property.
Concertina wire can also be used to keep animals from grazing on crops or getting onto a construction site.
Concertina wire is also used in personal yards to keep people and animals away from a certain area. The razor-sharp spikes on concertina wire can cause serious injuries if people or animals touch it.
Maintenance of concertina wire
Concertina wire needs to be maintained to be a more efficient and effective means of protection. The wire needs to be maintained so that it stays straight and can easily be deployed. The maintenance of concertina wire requires wire cutters, one man and a patrol.
First, the wire is cut. Next, the wire is fixed. During the fixing process, the wire is locked in place to ensure that it will hold. When this is done, the wire is unfolded and deployed.
