Core, tape, and blades of Egoza form the structural and functional foundation of the barrier. The characteristics of these components – their composition, thickness, and connection method – define how reliable and intimidating the entire system is. Selecting the right configuration is critically important both at the design stage and when purchasing finished products.
Metal Core – the Load-Bearing Element
Inside every strip of reinforced razor wire lies a high-strength core – a wire made from carbon steel with increased carbon content. Spring or rope wire with a diameter of 2.3 to 2.8 mm is typically used, offering high hardness and tensile strength.
The core serves not only as a supporting element: it ensures flexibility, resilience, and the ability of the tape to retain its shape under any conditions. Thanks to the core, Egoza barriers can be coiled, stretched into spirals, and withstand mechanical impacts without losing their protective properties. The correct steel grade and its preliminary treatment (such as heat treatment) significantly affect product lifespan.
Razor Tape – the External Cutting Layer
The wire core is tightly wrapped with a steel tape with stamped blades. This tape is usually 0.5 mm thick and 20-25 mm wide. It is made from galvanized steel or stainless alloys, depending on corrosion resistance requirements and service life.
The tape is engineered to remain rigid and deformation-resistant when stretched. During stamping, sharp blades are formed – the very elements that provide deterrence and protection. The tape edges are typically rolled or compressed to minimize delamination and preserve the coating during use.
Blades – the Cutting Force
The blades on Egoza reinforced tape may vary in shape, length, quantity, and sharpening angle. They are arranged symmetrically along the center axis and angled outward, designed to snag clothing, gear, or the intruder’s body during crossing attempts.
Blade sharpness is achieved through precise angular cutting – not traditional sharpening, but slicing at a sharp angle to create dangerous edges. The number of blade pairs per tape section can vary from 2 to 5 or more. Denser placement increases effectiveness but also affects weight and flexibility. Some modern versions combine different blade types on one tape to add visual and physical deterrence.
Tape-to-Core Connection Method
The tape is affixed to the core using a cold pressing method on specialized equipment. This creates a permanent connection without welding, soldering, or adhesive. The result is high mechanical strength and suitability for use in environments with temperature fluctuations, vibrations, and external impacts.
It is essential that the pressing is applied evenly along the entire length – without gaps or distortions. Improper technology may lead to delamination or slipping of the tape over the core, compromising the reliability of the barrier.
How to Select the Right Configuration
When choosing reinforced razor wire, consider the intended environment. For temporary fencing, a standard galvanized tape and core will suffice, while long-term outdoor use requires a stainless-steel option with a reinforced core. For high-risk security areas, opt for tapes with an increased number of blades.
