Concertina razor wire is a type of Razorwire commonly used at prisons and other high security establishments.
Depending on the coil diameter, each loop is clipped in 3 or 5 places to the following loop. So, when extended, the Razorwire forms a tubular effect by which the gaps are too small to allow someone to climb through.
RazorwireUK offers varying types & sizes of Razorwire which are available to order online or over the phone. Please see below information regarding our various products.

Choosing your Razor wire
Choosing which Razorwire is best for you can be difficult. However, our team at RazorwireUK are happy to help & can offer suggestions based on your personal use.
Typically, the bigger the diameter the more of an obstacle/deterrent the Razor wire is. 450mm diameter is the smallest size we recommend for domestic installations. This size is an adequate deterrent and also the easiest to fit, as standard support brackets will be suitable for this diameter and weight of the razor wire. 730mm & 900mm diameter will require specially made brackets for an installation.
If fitting to the ground then we recommend a size that can’t be vaulted over, then the suggested options would be to install a single run of 900mm diameter Razorwire or alternatively, stack smaller diameter Razorwire on top of each other either vertically or in a pyramid fashion.
Handling and PPE
The biggest misconception with handling Razorwire is that cut resistance Gloves and protective clothing are sufficient. The handler should always use the highest level of puncture-resistant PPE to prevent injury whilst installing. Our own brand of PPE called RazorPro is rated to Class 5 cut & puncture resistance which is the highest level of protection available in a material type format.

High Quality Specification
One way in which the industry maximise profits is disguising the razor wires specification. If the specification is not clearly stated then you may not be getting value for money!
Don’t Forget your Protective Equipment!

Points to note when selecting Razor Wire
- The core wire diameter:
2.5mm is 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 more expensive, but offers greater durability especially in salt air environments. Over time Stainless Steel will outlast Galvanised, therefore making it the best long term option. 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 & therefore reflected in the price.
- Blade thickness
0.5mm is the industry standard, anything less is likely to bend easily.
