CONCERTINA - razor wire



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 many 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. Their first upgrade was from short blade to medium blade. Medium blade razor wire had a much sharper edge and quickly gained the reputation of being an extremely effective low cost security product.

The next big step came when Cochrane introduced the ripper profile. The ripper blade has all the advantages of medium blade profile and adds a high ridged re-enforcing flange . The re-inforcing flange adds a high degree of strength making it particularly difficult to crush, trample or cut. Other blade profiles which incorporate this ridged flange include the tangled barrier as well as a military version of the ripper profile.

Other products which incorporate these blade profiles include: Razor Mesh, Electro-coil, Mobile Security Barriers, Ribbon Mesh, Ribbon Strip, Razor Strip, Clearvu mesh, Floatation Security Barriers, Hand deployment barriers. Many other products have been designed and manufactured by Cochrane Steel Products to provide for all security requirement.
