Egoza Barrier Construction
Egoza barrier construction is a precisely engineered system consisting of razor tape with sharp blades, a wire core, connecting elements, and fastening hardware. The performance of the entire security system depends on the accuracy of each component. Egoza’s construction forms the basis for all types of barriers – from concertina wire to mobile systems. Its internal structure determines the strength, durability, service life, and resistance to intrusion attempts. Understanding how it works is crucial not only for manufacturers and engineers but also for clients selecting the right barrier for specific site conditions.
The construction of Egoza is based on three elements: a metal core, a cutting tape, and a fastening system. In standard form, the reinforced tape is crimped tightly around a steel wire core, forming a solid connection resistant to mechanical stress, bending, and temperature fluctuations. During stamping, sharp blades are formed along the tape, providing both deterrent and injurious properties. The system is designed to operate in all climates – from coastal zones to plains and mountainous regions.
Wire Core – the Backbone of Structural Strength
The core is a round steel wire 2.3-2.8 mm in diameter, made of high-carbon steel. It bears the main mechanical load during tension and coiling. Thanks to the high elasticity and strength of the wire, the structure retains its shape even after repeated installation and removal. Thermal treatment quality is also important – a hardened core better resists bending and does not fracture under impact or pressure.
Both standard structural steel and corrosion-resistant alloys are used. For high-load and long-term applications, spring steel cores with anti-corrosion coatings are recommended, significantly extending the product's lifespan.
Razor Tape – the Outer Protective Layer
The stamped metal tape is tightly crimped onto the core wire and serves as the main deterrent. The tape is 0.4-0.6 mm thick and 20-25 mm wide. Sharp outward-facing blades are stamped at acute angles along the length of the tape, providing a cutting effect on contact and creating a strong visual and psychological barrier.
Blade shapes vary – straight, triangular, serrated, or double-edged. Blade spacing and length depend on the intended use. Denser layouts are used for military facilities and high-security zones, while wider spacing is acceptable for civil or temporary applications. In all cases, the tape must be evenly crimped to prevent slippage or detachment from the core.
Dimensions, Density, and Barrier Configurations
Egoza barrier sizes are primarily determined by spiral diameter. Available options range from 400 mm to 1500 mm, suitable for reinforcing fences or creating standalone perimeter defenses. The number of coils per roll and the spacing between clips directly affect the length, flexibility, stability, and visual density of the barrier. A standard roll stretches to 8-15 meters and is secured with 3-7 clips per coil (always an odd number to balance the load).
Special modifications are also available: double spirals, flat panels, pyramid structures – all built on the same base design: tape + core + connectors. Reliability and effectiveness depend on consistent manufacturing standards at each stage.
Corrosion Protection – Key to Longevity
All Egoza structures are exposed to weather – rain, snow, sea winds, and industrial emissions. Various corrosion protection methods are used. The standard solution is steel galvanization (hot-dip or electroplated). For harsher environments, AISI 304 or 316 stainless steel is used, often with additional passivation treatment.
It is essential that all components are protected – not only the tape and core, but also connectors like clips, wire, and mounting hardware. This ensures long-term durability, particularly on exposed perimeters or near sources of moisture.
How Construction Affects Barrier Selection
When designing a security perimeter, consider construction characteristics – stiffness, elasticity, weight, blade shape, and mounting method. For example, flat barriers are ideal for façades or mesh fences with limited width, while large-diameter concertina wire or pyramid barriers are better for creating bulky obstacles.
