Egoza concertina wire is a factory-assembled barrier of reinforced razor tape that, when stretched, transforms into a spiral with a diameter of 400-1200 mm. Clips hold the coils at a fixed distance, creating diamond-shaped cells that are nearly impossible to cut or spread using tools. The result is a durable and visually intimidating fence widely used at military bases, energy facilities, warehouses, and in the private sector.
Construction and Operating Principle
- High-tensile spring steel core wire Ø 2.4-2.5 mm withstands tensile loads exceeding 1600 N.
- Razor tape 0.5 mm thick is stamped at an acute angle, forming blades capable of cutting soft materials during intrusion attempts.
- Factory-installed galvanized steel clips are positioned at intervals of 250-300 mm to securely fasten adjacent coils.
- Zinc or Al-Zn coating ≥250 g/m² provides corrosion resistance for more than 25 years without re-coating.
- The spring effect of the spiral causes the wire to "close" after deformation, making it difficult to cut through sections.
Selecting Diameter and Clip Spacing
Diameters of 400-600 mm are ideal for mounting on top of existing fences; 900-1200 mm are optimal for ground installation with brackets; 1200 mm and larger are used for creating pyramidal barriers or highly resistant double-layer defenses. The smaller the clip spacing, the more rigid the structure and the longer it takes for an intruder to breach each meter of the perimeter.
Advantages Over Standard Barbed Wire
- Seven to ten times longer breach time due to multiple rows of blades.
- Supplied in compressed coils: one pallet holds up to 960 meters of ready-to-install barrier, saving about 30% on logistics costs.
- Installation without special tools: two workers are sufficient.
- Guaranteed cell geometry provides an aesthetic appearance and even load distribution on fasteners.
- Compatibility with vibration sensors and tension alarm systems.
Three-Step Installation
- Unroll the coil along the fence line, temporarily securing the end coils.
- Fix the spiral to posts or directly into the ground using galvanized clips and tension wire.
- Connect adjacent sections with clips, maintaining the specified clip spacing. On average, a 100-meter barrier can be installed by a two-person crew in less than an hour.
Certificates and Legal Protection
The production of Egoza concertina wire is certified according to ISO 9001 standards, and the name "Egoza" concertina wire is protected as an international trademark. Unauthorized use of the brand or copying of the blade profile leads to legal liability (more details available in the /info/legal section).
