Galvanized Razor Wire 

High-Security Galvanized Razor Wire | Concertina Barbed Tape BTO-22 CBT-65 | Hot-Dipped Galvanized Razor Barbed Wire for Perimeter Security - [SONGCHEN STEEL]

01. Product Overview

Our Galvanized Razor Wire, also known as Concertina Barbed Tape, is the ultimate high-security barrier designed for maximum deterrent and physical protection. It consists of a high-tensile core wire reinforced with sharp, punched-steel blades. The spiral or crossed-loop structure creates an impenetrable obstacle that is extremely difficult to cut, climb, or bypass.

Engineered with premium Hot-Dipped Galvanized (HDG) coating, our razor wire offers exceptional resistance to weathering and corrosion. It is the gold standard for securing military bases, prisons, borders, airports, and high-value industrial perimeters where security is non-negotiable.

02. Key Features & Advantages

l  Extreme Psychological & Physical Deterrent

Ø  Feature: Sharp, multi-pointed steel blades (BTO-22 / CBT-65).

Ø  Advantage: Creates a visual and physical threat that is nearly impossible to grip or climb without specialized equipment.

Ø  Benefit: "Zero Intrusion." Proactively prevents unauthorized access by causing immediate physical harm to anyone attempting to breach the perimeter.

l  High-Tensile Anti-Cut Core

Ø  Feature: High-carbon galvanized steel core wire (typically 2.5mm diameter).

Ø  Advantage: High tensile strength (up to 1500MPa) makes it extremely resistant to standard wire cutters and manual tampering.

Ø  Benefit: "Unbreakable Security." Ensures the barrier remains intact even under deliberate attack, providing continuous protection.

l  Superior Hot-Dipped Galvanizing

Ø  Feature: Heavy zinc coating (up to 275 g/m²) applied to both the core and the blades.

Ø  Advantage: Provides a self-healing protective layer that prevents rust even in humid, coastal, or industrial environments.

Ø  Benefit: "Maintenance-Free Longevity." Extends the service life to 10-20 years, significantly reducing replacement and maintenance costs.

l  Flexible Concertina Structure

Ø  Feature: Cross-clipped double-spiral design with heavy-duty steel clips.

Ø  Advantage: Expands into a dense, interlocking 3D cylinder that covers a large volume and resists compression.

Ø  Benefit: "Rapid Deployment." Allows for quick installation on top of existing fences or directly on the ground to create an instant high-security zone.

04. Versatile Applications

l  Military & Border Security

Used as tactical barriers or permanent fences along international borders and military bases to prevent illegal crossings and unauthorized entry.

l  Prisons & Detention Centers

Installed on top of concrete walls or chain-link fences to create an impenetrable ceiling, effectively eliminating the possibility of escape.

l  Airports & Critical Infrastructure

Protects runways, power plants, and water treatment facilities from sabotage and trespassing, ensuring the safety of public services.

l  Industrial & Commercial Zones

Secure warehouses, chemical plants, and private estates from theft. Its high visual deterrent often prevents crimes before they are even attempted.

07. FAQ

Q1: What is the difference between BTO and CBT? Which one should I choose?

Ø  BTO (Barbed Tape Obstacle): Short blades (10-30mm), simple profile. BTO-22 is the global standard, balancing cost and deterrent.

Ø  CBT (Concertina Barbed Tape): Longer blades (usually 65mm), such as CBT-65. Extremely aggressive and very difficult to disentangle once caught.

Recommendation: BTO-22 for standard commercial/residential; CBT-65 for high-risk zones (prisons/borders).

Q2: What is the difference between Single Spiral and Cross Type (Concertina)?

Ø  Single Type: No clips, expands like a spring. Looser structure, suitable for low-cost civilian use.

Ø  Cross/Concertina Type: Adjacent loops secured with clips. Forms a rigid mesh cylinder with high compression resistance and superior protection.

Q3: How long will hot-dipped galvanized razor wire last outdoors?

Ø  In dry climates, standard HDG (40-60g) lasts 5-8 years.

Ø  With high-zinc coating (200g/m²+),  service life exceeds 15 years even in humid or coastal environments.

Ø  For 25+ years, upgrade to stainless steel (SS304/SS316).

Q4: How do I determine the coil diameter I need?

Ø  450mm: Most common, ideal for residential wall tops.

Ø  600mm / 700mm: Suitable for factory, warehouse, or substation fence tops.

Ø  900mm+: Often placed on the ground or atop prison walls for maximum vertical barrier.

Q5: How do you calculate the covering length per coil?

Ø  Covering length depends on stretch density.

Ø  Recommended: For 600mm coil diameter, 3-4 loops per meter yields optimal protection.

Ø  Example: A 56-loop, 600mm coil yields 8-10 meters coverage. The longer you stretch, the wider the gap.

Q6: Do you support custom labeling and packaging?

Ø  Yes. Custom adhesive labels or hang tags per coil with spec, length, and brand logo.

Ø  Packaging options: Marine packaging specifically designed for galvanized razor wire.

Q7: Does razor wire export require special export licenses?

Razor wire is classified as general steel products (HS Code 73130000) and is NOT on the 2026 restricted steel export catalog.

We handle full export documentation without special licenses, ensuring fast global customs clearance.

Q8: Why is your price higher than some other manufacturers?

Ø  Core strength: We use 1400MPa+ high-carbon steel, not cheap low-carbon wire (easily cut by standard cutters).

Ø  True zinc coating: We guarantee actual zinc weight — no passing off electro-galvanized as hot-dipped.

Ø  Blade density: Tighter blade spacing and sharper punching.

Q9: What professional tools are needed for installation?

Ø  Essential: Wear specialized cut-resistant heavy-duty leather gloves.

Ø  Tools: Wire cutters, tensioning tool (or lever bar), tie wire (for securing to brackets).

Ø  Brackets: Typically Y-type or I-type brackets mounted on fence tops.

Q10: Can you provide installation videos or on-site guidance?

Ø  We provide detailed installation manuals and instructional videos.

Ø  For large government or military projects, we can arrange remote video guidance by technical specialists to ensure safety compliance.
