Technical Roadmap

Concertina Razor Wire (Coil Type) Specifications & Performance

Concertina Razor Wire (Coil Type) represents the peak of physical security defense. Known for its distinct helical structural design, this barrier utilizes high-tensile core wire and razor-sharp steel tape clips designed to inflict structural damage to unauthorized trespassers and withstand shearing attempts by conventional tools.

Blade Profiles (BTO & CBT)

We manufacture dynamic razor blade types such as BTO-10, BTO-22, BTO-30, CBT-60, and CBT-65. The short blade BTO-22 is optimized for general commercial borders, while the heavy CBT-65 is deployed in high-security zones such as prison complexes and military installations.

Tensile Strength & Core Wire

Equipped with a core wire diameter of 2.5mm (±0.05mm), our security wires feature a structural yield limit of over 1500 MPa. Formulated from premium high-carbon steel, the wire retains structural shape under high tensile stress and resists manual leverage or cutters.

Double Loop Concertina Design

By connecting adjacent loops with heavy-duty clips (varying from 3-clip to 5-clip systems based on loop diameter options of 450mm to 960mm), the wire creates a multi-layered, non-deformable structural cylinder. This ensures zero physical gaps or vulnerability in placement.

German & Taiwanese Technology Integration

Precision Manufacturing From Raw Material To Finished Product

Sinsun Hardware implements strict quality controls beginning at the raw material phase. We source carbon steel wire rod from premier metallurgical bases such as Xingtai Steel, executing in-house spheroidizing annealing and subsequent precision drawing.

Our production relies on German multi-station cold heading systems and specialized Taiwanese razor stamping gear. The razor blade sheet and internal core wire are bound together using continuous hot-dip zinc plating or stainless steel wrapping, maintaining mechanical integration without slip or core separation.

Every single batch of Concertina Razor Wire undergoes a series of physical laboratory reviews, including dimensional blade profile checks, chemical alloy validation, coating thickness analysis, and minimum breaking load testing.

Corrosion Immunity Standards

Our hot-dip galvanized coating delivers long-term durability. We guarantee coating densities up to 275 g/m², enabling the wire to withstand 1000+ hours of continuous salt spray testing without rust formation, securing critical borders in high-humidity or coastal areas.


Stainless Steel Options: For marine environments, chemical facilities, or ultra-corrosive locations, we manufacture custom coils using AISI 304 or AISI 316 stainless steel core and strip alloys.

Procurement & Solutions

Global Enterprise Procurement & Application Scenarios

We work directly with procurement officers, engineering contractors, and government supply agencies to provide tailored defense barriers for challenging environments.

National Border Protection

Supplying border fence extensions. Double-coil concertina wires with a 960mm diameter and 5-clip structural configuration prevent unauthorized crossings across vast geographical expanses.

Military Infrastructure

Designed for rapid tactical deployment. High-tensile stainless steel BTO-22 coils are utilized in temporary defensive rings and military checkpoints, ensuring long-term field stability.

Correctional & Prison Facilities

High-security barriers. The large blade CBT-65 profile is combined with anti-climb mesh panels, providing a psychological and physical deterrent on wall tops.

Industrial Estates & Depots

Cost-effective security. Standard hot-dip galvanized BTO-10 and BTO-22 configurations are easily installed on top of existing chain-link perimeter fences for commercial logistics hubs.

Compliance & Safety Assurance

International Quality Certifications & Shipping Logistics

Our concertina wire production processes conform strictly to standard global procurement specifications, including EN ISO 1461, ASTM A764, and ASTM F1910 for barbed tape obstacles. This compliance ensures high performance under varying climatic stresses.

We understand the safety risks associated with handling razor wire. Because of this, Sinsun uses robust packaging designs to protect handlers and prevent product damage during transit. Coils are wrapped in heavy-duty moisture-proof paper or woven bags, then packed onto reinforced wooden pallets or steel crates for safe transport.

Our engineering support team offers comprehensive digital 3D design previews, detailed installation manuals, and shipping coordinate tracking for a reliable procurement process.

Frequently Asked Questions

Concertina Razor Wire (Coil Type) Purchasing FAQ

Get professional insights from our engineering division regarding technical specifications, selection, and bulk ordering procedures.

What is the structural difference between BTO-22 and CBT-65 razor wire profiles?
BTO-22 (Barbed Tape Obstacle 22) features a blade length of 22mm (±1mm), a blade width of 15mm, and a spacing of 34mm (±1mm). It is highly versatile and commonly used on standard commercial and industrial fences. CBT-65 (Concertina Barbed Tape 65) features a much larger 65mm (±2mm) blade length, 21mm width, and 100mm spacing. The larger blade profile provides a stronger visual and physical deterrent, making it suitable for high-security areas like correctional facilities and military bases.
Why is high-tensile core wire necessary for Concertina Razor Wire coils?
Low-tensile mild steel wires are easily cut using standard hand tools and can sag under physical pressure. Sinsun utilizes high-tensile spring steel wire (typically 2.5mm in diameter) with a tensile strength exceeding 1500 MPa. This high structural tension prevents cutting by ordinary wire cutters and ensures the coil retains its spiral shape when stretched, preventing unauthorized access.
What does the "clip count" mean (e.g., 3-clips vs 5-clips per loop pair)?
The clip count refers to the number of heavy steel clips that secure adjacent wire spirals together. A 3-clip configuration is typical for smaller coils (like 450mm) and provides a standard spatial density. A 5-clip configuration is used for larger coils (such as 730mm or 960mm) to create a denser, rigid cylindrical mesh that is difficult to flatten or compress, offering superior physical defense.
How does the zinc coating weight affect the service life of the barrier?
The lifespan of galvanized steel is directly related to the thickness of its zinc layer. Electro-galvanized coatings (10–15 g/m²) provide basic protection suitable for dry climates. Hot-dip galvanized coatings with a weight of 120–275 g/m² provide a thick protective layer that resists atmospheric corrosion, offering over 15 to 20 years of maintenance-free service in industrial and agricultural zones.
Do you supply custom OEM packaging and branding for bulk military/tender orders?
Yes, Sinsun Hardware specializes in OEM packaging and custom printing solutions. We provide custom labels, color-coded bands, specialized handling crates, and protective structural casings to meet military, industrial, or distribution requirements. Our design team can also provide 3D visual previews of the customized packaging configurations prior to manufacturing.
