Concertina Wire Security Barrier

Concertina Wire Security Barrier "EGOZA" is made of ASKL (reinforced twisted barbed tape) or AKL (reinforced barbed tape) correspondingly, formed in coils of specified length and diameter, its adjacent coil loops are clipped together alternatively by metal clips in 3, 5 (or more) equally spaced points around the coil diameter. When deployed (stretched) it looks like a barbed ribbed cylinder.

The prototype of “Egoza” Concertina Wire Security Barrier is Dannert wire, which was developed and became widespread during World War I as military-style wire obstacles. Structurally it is AKL or ASKL wire arranged in coils.

Available in options of 3 to 5 clips. The more clips are used, the denser and more rigid the resulting structure is, however the price per running meter also changes.

Besides, Concertina Wire Security Barrier with five clips is more difficult to cut – despite being cut in several points the structure retains its anti-climb properties.

Concertina Wire Security Barrier 500 “Egoza” is mainly installed on brackets on the top of metal fencing or concrete walls. Such type of barbed wire has a strong deterrent effect and finds wide civil, industrial and defense application.

Its upgraded version is huge 1700 mm-diameter structures "Obereg" and Concertina Wire Security Barrier “BARS” for high-security applications. At present Concertina Wire Security Barrier “Egoza” is one of the most effective physical obstacles against would-be intruders.

If you are looking for security barriers, “Egoza” works offers you excellent terms and conditions and the best prices in Chelyabinsk, Moscow, Miass, Ekaterinburg, Ufa, St.Petersburg and other regions!

How to calculate spiral loops of a concertina wire security barrier «Egoza»

Density of Concertina Wire Security Barrier “Egoza” depends upon number of spiral loops per meter and number of clips on the coil circumference.

Consumers often ask how to calculate spiral loops of Concertina Wire Security Barrier “Egoza”?

First, you need to learn how Concertina Wire Security Barrier is manufactured. Case study: Concertina Wire Security Barrier 500/15/5/3. The AKL barbed tape is wound on a drum.

The coil has a covering length, i.e. concertina fencing deployed length. In this case, it is 15 meters. So, 5 spiral turns per meter total 75 spiral turns per coil (15 meters * 5 turns).

Concertina Wire Security Barrier

Then adjacent coil loops are clipped together alternatively by 3 metal clips at regular intervals around the circumference. When calculating, note that two adjacent coil loops are clipped.

There are several ways to calculate the spiral loops of a finished product:

  1. When in coil: Count all loops in the coil and divide by the coil length in meters. For example, 93 coil loops. According to shipment documentation or label the coil length is 15 meters. 15 ÷ 93 = 6.2. The coil has 6.2 spiral loops per meter.
  2. The deployed coil length calculation is the same: to count all loops and to divide by coil length in meters.
  3. 3. In case of deployed coil: to measure one meter and to count spiral loops per segment. This way of calculation is not popular. It is difficult to calculate 6.2 spiral turns per meter by defining just one meter.
How to calculate the number of turns in a barbed wire
Sometimes suppliers make the following marking: 500/50/5 – it stands for: coil diameter 500 mm., 10 m covering length, 50 spiral loops per coil, 5 clips per spiral.

How to tighten a straining wire to install SBB (PBB)?

For this purpose, use a wire strainer when installing barbed wire SBB and PBB. It is a kit consisting of an eye-nut, a threaded pin, washers and nuts. The tensioner is installed on reinforced barb arms of the topping. The end of the 2.5-3.0 mm straining wire to be attached to the ring of the strainer. Tightness to be adjusted by rotating the ring of the eye nut. Straining wire sagging is recommended to be under 5 cm. Reinforced brackets to be installed on each 10th fencing post. Straining wire to be attached to the intermediate brackets by specific clips.

I would like to reinforce  the panel fencing with “Egoza”. The enterprise shares borders with the  residential area. Are there any specific recommendations for “Egoza” AKL installation for such facilities?

It is possible to upgrade the existing fencing with a concertina wire security barrier “Egoza”, however it requires measures on injury prevention. In residential areas, along sidewalks and pedestrian roads SBB to be installed high enough to exclude risk of contact with overhanging wire. If the fencing is higher than 2 meters, it is recommended to mount SBB “Egoza” on Y-shaped brackets on the 3D fencing posts. The second option is to install a concertina AKL on L-shaped brackets to overhang inside the industrial premises. In this case, AKL will be behind the fencing line, will remain safe for bypassers, but effective and clearly visible protection. The third option is to use a flat security barrier that does not protrude beyond the fencing plane. We recommend you to use warning signs and lighting.

Are there any GOST standards for “Egoza” concertina wire safety barriers?

There is no specific GOST standard for “Egoza” concertina wire safety barrier. Sometimes manufacturers and dealers mislead customers by specifying GOST standard of the core wire after the brand name. Therefore, when buying barbed tape AKL or SBB, PBB or PKLZ barriers, please, pay attention to the marking and if it indicates GOST, it is worth checking. “Egoza” Works  produces barbed wire in accordance with the technical specifications TU 25.93.12-016-99293177-2016 (new, to replace TU-1211-015-49144638-2011).

What is the difference between AKL and ASKL tapes?

AKL stands for Reinforced Barbed Tape. This is a special profile galvanized tape, 0.5 mm thick, with double-edged sharp barbs arranged symmetrically on both sides. The tape tightly covers a galvanized steel rope wire of 2.5 mm in diameter. AKL is fabricated by wrapping the barbed tape over the core wire. ASKL stands for Reinforced Twisted Barbed Tape, similar to AKL, a galvanized tape with barbs is used, but in this case, it does not wrap the steel core wire, but twists around it. Today, AKL tape is considered more advanced, widely spread and reliable.

09 October 2017
What is the standard SBB coil stretched length (concertina wire “Egoza”?)

There is no standard SBB coil stretched length. We offer a range of 10, 15, 20, 25 meters. Since the plant is a full-cycle manufacturer, we offer the best terms and conditions for our clients including customized SBB coil length.
