Products - Razor Wire / Barbed Tape
| Cochrane Razor Wire (Barbed Tape) is manufactured in accordance with specification NATO STK No. 5660/99-458-7414. The Unique Cochrane heavy duty clip is an important feature of the product. The weak link in some brands is the clip, which binds the wire into its tubular/concertina shape. A weak clip will part, providing an easy access point for the intruder. COCHRANE incorporates a unique heavy duty steel clip designed to withstand
a force of approx. 200lbs/100kgs, which cannot be parted by hand or with standard tools. |

Development of Razor Wire Concertina from Barbed Tape / Wire
Originally barbed wire fulfilled the roll of perimeter security. As crime has escalated barbed wire became less and less effective. Petty thefts worsened and the need arose to replace barbed wire with a more effective alternative. The breakthrough came when a barbed fashioned tape was added to a high tensile wire. This product was given the name barbed tape / razor wire! The original product had short blades which were substantially more effective then the barbed wire product. Cochrane Steel pioneered the way forward from this point on. Realizing the barbed tape product modeled on the barbed wire was not nearly as effective as it could be they designed medium blade. Medium blade razor wire had a much sharper blade and quickly gained the reputation of being a low cost effective security product.
Perhaps the biggest development came when Cochrane introduced the ripper profile. The ripper took the medium blade profile and added a re-enforcing flange (see ripper specification). This simple development added so much strength to the coil it is now particularly difficult to crush or trample and even more difficult to cut than the previous products. Recently Cochrane introduced the tangle barrier as well as a military version of the ripper profile. As the blade profiles have increased so have the options of product Cochrane's offer. Razor Mesh, Electro-coil, Rapid Wire systems, Ribbon Mesh, Ribbon Strip, Razor Strip, 358 mesh, Hand deployment barriers as well as many other products have been designed and manufactured by Cochrane Steel Products to provide for any security requirement.
Razor Wire / Barbed Tape Specifications
| Razor Wire Blade Profiles |
1) Razor Wire Short Blade Profile
This is the original profile of Razor wire barbed tape, developed for military applications. Although mostly replaced by medium blade, it is still preferred by some organisations.
 
|
2) Razor Wire Short Blade Ripper Profile
The ordinary short blade profile was designed for military use, it has now been upgraded to incorporate a reinforcing flange. This improvement increases its resistance to cutting and makes it more rigid.
 
|
3) Razor Wire Medium Blade Profile
An improvement on the short blade at a cost-effective price level. Used widely for commercial and industrial applications.
  |
4) Razor Wire Ripper Blade Profile
Ripper razor wire has become the most popular seller because it is very effective yet competitively priced. It incorporates longer, sharper blades and a reinforcing band, which substantially improves rigidity of the coil. Overall it is more dangerous to handle and tougher to cut.
  |
5) Razor Wire Long Blade Profile
A vicious product when manufactured of toughened stainless steel blade material. It is usually used for Prison fencing.
 
|
6) Razor Wire Ribbon Blade Profile
Ribbon blade is generally welded onto the top of security fencing mesh. The end product provides an all-in-one anti-intrusion mesh, which is cost effective (saves extra labour to install razor coil) with a neat and pleasant appearance.
