As border security challenges evolve, so do the physical barriers designed to counter intrusion attempts. Pauleen's razor wire portfolio combines decades of on-site expertise with advanced manufacturing precision. Whether for national borders, critical infrastructure, or high-security perimeters, our solutions deliver proven deterrence and structural integrity.
1. Flat-Wrap Concertina Coils – The Foundation of Rapid Deployment
Our flat-wrap concertina coils (also known as flat concertina barbed tape) are manufactured using high-tensile galvanized steel core wire and precision-stamped bi-polar razor blades. Key technical specifications include:
Blade type: 22×22mm or 22×30mm, 0.5±0.05mm thickness, 304/430 stainless steel or galvanized surface treatment
Core wire diameter: 2.5 mm ± 0.1 mm, with tensile strength ≥ 650 N/mm²
Coil diameter: 450 mm, 500 mm, 600 mm, or 700 mm (upon request)
Number of loops per meter: 13–17, depending on coil diameter and compression ratio
Cover length after extension: 7–10 meters from a compressed length of 500–800 mm
Flat-wrap coils are shipped in bundled, compressed form for efficient logistics. Once deployed, they spring back to their full diameter, creating a dense, threatening barrier that resists cutting, climbing, and forced crossing. Typical applications include rapid border fencing, temporary checkpoints, and perimeter reinforcement layers.
2. Concertina Barbed Tape (CBT) – Heavy-Duty Perimetric Defense
For high-risk border segments, Pauleen offers Concertina Barbed Tape (CBT) in cross-helical configurations (single or double helix). The barbed tape features:
Blade length: 22 mm ± 1 mm, width 15 mm, spacing ≤ 34 mm
Breaking load of barbed tape: ≥ 220 kg per strand
Corrosion resistance: 240+ hours salt spray test (ASTM B117) for galvanized products; ISO 9227 for stainless steel grades
Installation methods: Ground-mounted (Y-posts, U-posts) or wall-top mounting with tilt-out arms
Our CBT-65 and CBT-70 models are widely deployed in Schengen border reinforcement and US CBP pilot projects. The scalability of these coils – from single-row low-profile barriers to triple-stack high-density configurations – makes them adaptable to any threat level.
3. Integrated Anti-Climb Wall Systems – Beyond Standalone Coils
Recognizing that modern border breaches often target vertical walls with ladders or grapple hooks, Pauleen has developed fully integrated anti-climb wall systems. These systems combine razor wire with structural overhang designs, creating a no-handhold, no-footing barrier that defeats both manual and aided climbing.
Key components of our integrated solution:
Wall-top anti-climb brackets: Fabricated from 50×50×3 mm galvanized steel angle profiles, bolted every 1.2 m to the wall coping. Brackets extend outward at 30°–45° angles, supporting 3–5 runs of concertina coils.
Flat-wrap infill layers: Installed between bracket runs to eliminate gaps. The infill uses flat-wrap coils with tighter loop density (18 loops/m) to prevent tool insertion.
Base and mid‑rail razors: For walls below 2.5 m, we add mid‑height razor ribbons secured by tensioned barbed wire (Ø 2.8 mm, 4-point barb spacing) – a proven psychological and physical disincentive.
Anti-cut and anti-pry features: All bracket bolts are shear-resistant and welded after tightening. Coil tie wires are 2.0 mm galvanized steel, triple-wrapped per connection point.
Integration does not stop at hardware. Pauleen's design team works with border agencies to incorporate sensor-ready mounting points for fiber-optic vibration detectors or electric fence terminals. This transforms a passive razor wire barrier into an active detection and denial system.
4. Manufacturing Excellence – Why Pauleen Stands Apart
With over a decade of exclusive focus on razor wire production, our factory (owned and operated under Pauleen) maintains strict quality control in line with ISO 9001:2025 and EN 1827:2024 (tentative). Every batch is tested for:
Blade sharpness and edge consistency (no burrs or deformation)
Coil spring-back ratio (≥ 85% of nominal diameter after six months of storage)
Galvanized coating uniformity (zinc weight ≥ 180 g/m², ASTM A653)
We also offer custom blade stamping – diamond-pattern or wave-pattern barbs – for unique deterrence requirements. Lead times for non-standard coils are 10–15 working days.
5. Case Reference: Integrated System on a National Border (Project Anvil)
In Q4 2025, Pauleen supplied a 1.8 km double-layer anti-climb wall system for a South Asian border crossing. The solution included:
Top row: 5 runs of CBT-70 cross-helical coils on 45° brackets
Middle layer: Flat-wrap concertina infill (500 mm diameter coils, 15 loops/m)
Bottom bundle: Two compressed flat-wrap rolls as ground-level deceleration traps
Outcome: Zero recorded climbs over eight months of live surveillance; maintenance cost reduced 60% compared to previous rotating-spike designs.
6. Global Shipping and On-Site Advisory
We ship directly from our factory in China to any port worldwide. All razor wire is packed in wooden pallets or cardboard spools, wrapped with anti-corrosion paper. A detailed installation manual (including bracket spacing, coil overlap calculations, and tensioning torque values) accompanies every order.
