CBT 65 Concertina L Type Razor Barbed Wire

CBT 65 Razor Wire Concertina L Type Razor Wire Fencing Barbed Wire Concertina

CBT 65 / Concertina L type

The CBT 65 / Concertina L type model is defined by its 65 mm wide blade (this type of blade, together with the Concertina Super H model , are the two models with the longest blade), belonging to the group of the most aggressive models of concertinas, with a distance between blades of 100 mm . Concertina L type contains extra wire reinforcement, this reinforcement located on both sides of the wire and with a height of 2 mm, provides the concertina with extra reinforcement to increase its resistance.

The diameter of this type of concertina is 450 mm – 1500 mm, but have different action on other models of concertinas, special measures such as 630.700, 815 or 957 mm.

Mostly the CBT 65 made into SINGLE COIL type, without clips. Please check the details here. 

The L type concertina made of stainless steel or galvanized, with high resistance wire 1400 - 1600 Mpa .

• Stainless Steel EN 1.4016 - AISI 430
• Stainless Steel EN 1.4301 - AISI 304
• Stainless Steel EN 1.4401 - AISI 316
• Galvanized Steel Z40 - Z275
• Wire Strength: 1400 - 1600 MPa
• No. loops: 55 ± 1

The sectors that demand this type of concertinas are places with high levels of security , such as prisons or military bases, among many others.

• Borders
• Embassies
• Military bases
• Prisons
• Explosives warehouses
• Air bases

Choosing your Razor wire

Typically, the bigger the diameter the more of an obstacle/deterrent the Razor wire is. 300mm and 450mm diameter is the smaller 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 Razor wire or alternatively, stack smaller diameter Razor wire on top of each other either vertically or in a pyramid fashion.

Points to note when selecting Razor Wire

• Blade thickness

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

• 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 Razor wire 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 Razor wire.

• Stainless Steel or Galvanized?

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 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.
