Sizes and modifications of Egoza razor wire allow the barrier to be adapted to any conditions – from temporary closure of small areas to securing high-security facilities with perimeters stretching tens of kilometers. The variety of coil diameters, loop density, and configurations provides wide application flexibility. Sizes and modifications are a system of parameters used to select the appropriate barrier type. The right choice affects deterrent efficiency, ease of installation, and structural durability. Manufacturers offer different coil diameters, coil lengths, clip spacing, and combined barrier options.
Coil Diameters
One of the key parameters when selecting Egoza is the outer diameter of the coil. It determines not only the height and width of the barrier but also its psychological impact on an intruder. The most common diameters are 400, 500, 600, 700, 900, 950, 1250, and 1500 mm. Smaller diameters are used for fence reinforcement, while larger ones are intended for standalone protection lines.
For example, a 600 mm coil is suitable for installation on top of a fence, while a 900 mm coil can form a full-fledged ground barrier. Diameters of 1250 mm and above are used to create pyramidal barriers or large fixed structures in areas with high intrusion risk.
Coil Length and Deployment Density
Each Egoza coil contains a specific number of loops, joined together with clips (always in odd numbers). This ensures the structure remains intact and evenly tensioned during deployment. Standard coils can stretch from 8 to 15 meters, depending on diameter and number of clips.
The tighter the loops, the more rigid and difficult the structure is to breach. However, higher density also reduces the effective length of the coil and increases the amount of material needed. Optimal balance between effectiveness and cost-efficiency is achieved through careful selection of diameter, loop count, and clip spacing.
Number and Positioning of Clips
Clips connect adjacent loops and prevent the coil from unravelling. According to standards, 3, 5, 7 or more clips are used per loop. An odd number ensures symmetrical load distribution and consistent unfolding.
More clips provide a denser and more stable barrier but also increase weight and installation effort. For temporary barriers, 3-5 clips may suffice, while permanent or mobile setups are best constructed with 7 or more.
Modifications Based on Purpose
Manufacturers offer both standard and reinforced Egoza options, differing in core type, tape thickness, blade shape, and connection method. Specialized variants are also available – frost-resistant, tropical, or anti-vandal (featuring reinforced clips and double fastening).
The most advanced modifications are dual-layer or combined systems, where the inner coil may be electrified (subject to legal approval), and the outer one acts as a visual and physical deterrent. These are used on critical sites with high threat levels.
How to Choose the Right Option
Your choice depends on the site's nature, operating conditions, required service life, and installation specifics. For temporary use, a small-diameter Egoza coil with 3 clips may be sufficient. For industrial or military sites, choose a reinforced version with a larger diameter and denser loop binding.
