Egoza barrier installation covers the full cycle of work – from perimeter line preparation to seasonal maintenance. The same algorithm applies to Egoza razor wire, concertina wire barriers, flat security panels, and razor mesh sheets, allowing installation crews to switch between projects without retraining.
Perimeter Preparation
- Mark the fence axis with stakes every 2.5 meters and level the ground: the permissible height difference is no more than ±50 mm.
- Check underground utilities according to as-built drawings; if cables are present, install the barrier on a concrete base or pile foundations.
- Plan gate entry points: leave a gap of at least 300 mm between the gate edge and the start of the barrier to prevent blade entanglement.
Concertina Barrier Installation
One Ø 700 mm coil, 10 meters long, can be installed by two operators in approximately 15 minutes:
- Lay out the coil along the fence line and temporarily secure the end loops with binding wire.
- Fix Y-shaped posts (60×40 mm) to the concrete base or 500 mm deep concrete blocks using M10×100 anchors.
- Stretch a safety steel cable Ø 4 mm through the centers of the coils and fix it with turnbuckles; this prevents sagging over spans longer than 50 meters.
Flat Barrier Installation
- Posts: 60×60×3 mm profile; embed into concrete footings to a depth of at least 800 mm.
- The panel is attached with M8×40 anti-vandal bolts and pressure washers through a reinforcing bar to avoid tape deformation.
- Overlap between adjacent panels – 120 mm, tightened with four bolts to prevent gaps due to thermal expansion.
Razor Mesh Installation
The mesh is fastened to horizontal rails (40×20 mm) with bolts. Lower the bottom edge 50 mm below the rail level to prevent prying with a crowbar. At perimeter corners, overlap the mesh sheets by 150 mm and secure them with clips every 150 mm.
Mobile Barrier Installation
- Unfold the frame on the ground and lock the hinges with “dovetail” latches – full deployment takes 30-40 seconds.
- Drive two 700 mm ground anchors diagonally through the frame and secure the end coils with a tension strap.
- For lines over 30 meters, connect sections with S-shaped hooks every three coils to prevent accordion folding in winds over 15 m/s.
Alarm System Integration
The vibration sensor cable is attached to the reinforced razor wire core with plastic ties spaced every 400 mm. The cable should be positioned at the "six o'clock" position (bottom of the loop) to protect it from direct tool impact. Controllers are placed in hermetically sealed boxes every 100 meters and powered via PoE lines.
Maintenance and Regulations
- Check cable tension quarterly: allowable sagging ≤2% of the span. If necessary, tighten the turnbuckle by half a turn.
- Measure the zinc layer thickness every two years with a magnetic gauge. If the reading is 220 g/m², apply a zinc-rich restoration coating.
- After hurricanes or ice storms, inspect the clips – replace them if torn; damaged blades should be replaced with a 1.5-meter section.
Safety Requirements
Installers must use cut-resistant aramid fiber gloves rated EN 388 (4544) and protective goggles. When working at heights above 1.8 meters, a fall protection harness with a strap width of at least 35 mm is required. Cutting razor tape with an angle grinder without a heat shield is prohibited – sparks reduce the lifespan of the zinc coating.
Common Errors and Prevention
- Installing concertina without a safety cable – leads to sagging and clip rupture within 2-3 years.
- Using construction screws instead of anti-vandal bolts – compromises electrical isolation and may cause stray currents.
- Attaching panels to thin-walled posts – wind vibration leads to cracking of welded joints; minimum post wall thickness is 3 mm.
