CBT Series Razor Wire: Industry Evolution & Specifications

Understanding the transition from BTO (Barbed Tape Obstacle) to CBT (Concertina Barbed Tape) profiles, coating standards, and alloy selections.

Modern security threats demand physical defense networks that act not just as passive deterrents, but as actively impassable physical structures. The CBT (Concertina Barbed Tape) series is characterized by its extended razor profiles and aggressive blade configurations. Unlike traditional BTO-10 or BTO-22 variants, CBT-65 and CBT-60 models exhibit heavy-duty steel blades measuring up to 65mm in length, intentionally spaced and shaped to ensure maximum entanglement and laceration potential upon unauthorized contact.

Global architectural standards require these structures to maintain absolute structural integrity under extreme conditions. Environmental weathering, industrial chemical exposures, and mechanical shearing attacks represent standard operational stressors. Sinsun address these challenges through two primary metallic pathways: high-purity hot-dip galvanization (ranging from 120 g/m² to 275 g/m² protective zinc coatings) and marine-grade stainless steels (SUS304, SUS316). Our mechanical integration process uses a heavy mechanical press to bond the steel strip around the high-carbon steel wire core, producing a composite structure that resists separation by common hand tools.

CBT-65 Blade Configuration

Featuring a massive 65mm blade length, 21mm blade width, and 100mm center-to-center blade spacing. Engineered specifically for high-security perimeters, border zones, and defense facilities.

CBT-60 Blade Profile

Features hook-like blades measuring 60mm in length. Designed to optimize the balance between physical structure weight and defensive entanglement density, perfect for wall toppings and perimeter overlays.

High-Tensile Wire Core

Utilizes spring-grade high-carbon steel wire with a tensile strength exceeding 1500 MPa. Resistant to mechanical cutters, ensuring the Concertina coils retain their circular shape under pressure.

Corrosion Resistance Standards

Complies with ASTM F1910 and EN 10244-2 standards. Tested to exceed 1000+ hours in salt spray testing environments, ensuring decades of performance in humid or coastal climates.

Frequently Asked Questions: CBT Razor Wire

Technical answers directly from Sinsun's engineering division to support your procurement process.

What is the key technical difference between CBT-65 and BTO-22 razor wire?
The difference lies in blade geometry and sizing. BTO-22 features a 22mm blade length and is typically used for general industrial applications. CBT-65 features a much larger 65mm hook-style blade designed for maximum entanglement, creating a stronger physical deterrent for high-security sites like military installations.
How does Sinsun prevent the razor tape from separating from the core wire?
We use specialized heavy-duty crimping machinery to mechanically bond the sheet-metal razor tape directly around the high-tensile core wire. This ensures the steel tape remains securely wrapped, preventing intruders from stripping the sharp blades off the core wire.
Which steel grades are used for Sinsun's CBT Razor Wire series?
We source our steel coils and rod products from reputable domestic mills, including Xingtai Steel. For the wire core, we process high-carbon steel wire (tensile strength ≥ 1500 MPa). For the razor tape, we use high-grade galvanized carbon steel or stainless steels (typically SUS304 or SUS316) based on the environmental requirements of the installation site.
Can Sinsun custom-manufacture razor wire roll diameters and loop numbers?
Yes, our flexible production processes allow us to customize roll diameters (ranging from 450mm to 1000mm) and vary the loop counts and spacing. We also provide customized heavy-duty clip styles (3-clip or 5-clip systems) to adjust the density and rigidity of the Concertina configuration.
What documentation is provided to verify corrosion protection?
Every shipment includes comprehensive Mill Test Certificates (MTC) detailing chemical composition, tensile strengths, and zinc coating thickness (expressed in g/m²). Upon request, we can also provide salt-spray testing reports verifying corrosion resistance up to 1000+ hours.
