Concertina Razor Wire

Concertina razor wire is the normal type of Razorwire you see around prisons and high security establishments.

The Concertina Wire or razor wire is a type of jagged wire produced of galvanized or stainless steel, manufactured in large coils which can be expanded like an accordion, characterized as an element of passive safety. Each loop is clipped in 3 or 5 places depending on the coil diameter to the next loop so when it is extended it forms a tubular effect that has gaps too small for someone to climb through.

Main function of the Concertina Wire is to form the concertina perimeter areas, high security, deterrence to prevent the intrusion of outsiders to a restricted area. The concertina is used in various sectors of industrial, military and governmental type among many other places.

Through the spiral form which is manufactured, its installation does not require any complex work, it can also be installed in walls, mesh fences, fence panels and other vulnerable areas.

The Concertina razor Wire design to provided with highly resistant blades, has a great capacity of penetration, while producing a deterrent to potential intruders.

Long Barb: CBT-65, CBT-60 Popular in Low level confinement and detention applications. Low level utility companies, airport perimeters, warehousing, manufacturing, parking lots, storage areas.

Points to note when selecting Razor Wire

The core wire diameter:

2.5mm and 2.8mm are the industry standard, anything less has proportionately less tensile and inherent strength.

The number of loops per coil

This determines the amount of Razorwire on the coil and therefore the profile density when deployed, an important point when comparing prices. All our coils have 55 loops per coil, this means the coils can be extended easily up to 10m whilst maintaining a dense profile of Razorwire.

Stainless Steel or Galvanised?

The environment the product is being deployed in may determine whether Stainless Steel or Galvanised is the best option. Stainless Steel is considerably more expensive but offers greater durability especially in salt air environments and over time will outlast Galvanised therefore making it the best long term option in salt air. However Galvanised is more than adequate for most UK regions and applications. We would always suggest you check the level of zinc coating when selecting Razorwire, all our Galvanised products are 200g/m2, if the supplier cant provide the information, you may only be getting a product with 60g/m2 which will deteriorate and rust much more quickly.

Blade type

Smaller blades such as BTO10 (10mm) are quite small and therefore less of a deterrent, larger blade profiles such as CBT65 (65mm) are much more effective but the blade type will also be reflected in the price.

Blade thickness

0.5mm is the industry standard, anything less is likely to bend easily.
