Direct supply from Sinsun Hardware's state-of-the-art facilities, certified to global mechanical integrity standards.
Sinsun Hardware operates Northern China's largest integrated fastener manufacturing hub. With a facility spanning over 30,000 square meters, we maintain a dedicated workforce and advanced infrastructure designed to produce up to 36,000 tons of high-performance hardware annually.
Our infrastructure includes a 12,000 square meter smart warehouse with an 18,000+ pallet capacity, running dynamic logistics routines via centralized ERP systems. Currently, Sinsun coordinates the logistics of over 8,500 shipping containers per year, serving industrial hubs in the Middle East, Southeast Asia, South America, and Eastern Europe.
In high-security border protection, infrastructure security, and military zones, security barriers require materials with maximum mechanical strength and psychological deterrence. The CBT (Concertina Barbed Tape) Series Razor Wire represents the industry standard for physical perimeter defense. Unlike standard barbed wire, CBT series razor wire features sharp steel blades stamped from high-tensile steel bands wrapped around a high-tensile core wire.
The CBT series is defined by blade length, spacing, and width. The most common variants are the CBT-60 and CBT-65 models, designed for extreme perimeter protection.
| Parameters & Specs | CBT-60 Specs | CBT-65 Specs | Testing Standards |
|---|---|---|---|
| Blade Thickness | 0.6 mm ± 0.05 mm | 0.6 mm ± 0.05 mm | ASTM A764 |
| Blade Length | 60 mm ± 2 mm | 65 mm ± 2 mm | Calibrated Micrometer |
| Blade Width | 32 mm ± 1 mm | 21 mm ± 1 mm | ISO 9001 Audited |
| Blade Spacing | 100 mm ± 3 mm | 100 mm ± 3 mm | Laser Distance Meter |
| Core Wire Tensile Strength | ≥ 1,500 MPa | ≥ 1,500 MPa | GB/T 343 / EN 10223 |
| Zinc Coating Density | Z275 (275 g/m²) | Z275 (275 g/m²) | ASTM A90 / EN 10244 |
Sinsun Hardware manufactures CBT razor wire to withstand severe environmental conditions. High-security environments like coastlines, chemical storage yards, and desert borders expose wire barriers to accelerated corrosion. To prevent structural failure, we implement precise metallurgical controls:
Analysis of high-security perimeter fence technologies and geopolitical procurement requirements.
Utilities, data centers, and transportation hubs are upgrading physical perimeters. Double-layer concertina wire systems featuring CBT-65 profiles are increasingly mandated to replace standard chain-link configurations.
Global procurement teams now require ISO 1461 and ASTM certification. Environmental protection regulations demand heavy zinc-coatings free of hexavalent chromium (Cr VI), standardizing Z275 and Zn-Al alloy options.
Modern defense systems integrate fiber-optic detection cabling directly onto the CBT razor wire array. Sinsun's precision dimensional tolerances ensure secure sensor mounting and zero false-alarm mechanical slippage.
Combining automated cold-heading, heat-treatment control, and custom packaging in a vertically integrated factory.
Our production fleet features over 200 German-imported multi-station cold-heading systems running 24/7 alongside high-speed progressive dies, outputting up to 1,200 parts per minute with micron-level tolerances.
We run four computer-controlled atmospheric heat-treatment systems with a combined daily capacity of 20 tons. Precise temperature ramps yield consistent HRC 28-32 hardness and fatigue limits exceeding 50,000 cycles.
We utilize an advanced ERP-driven warehousing system spanning 12,000 square meters. Automated barcode sorting routes up to 3,000 cartons per hour, enabling rapid container consolidation and load optimization.
From initial design audit through to shipping, our processes are designed to provide procurement security and product traceability.
01. Requirement Profiling: We analyze environmental conditions, mechanical load requirements, and regional standards to confirm product grades.
02. Prototyping & Verification: Our engineering lab provides physical samples, mechanical test reports, and 3D design previews.
03. Quality Control: Mass production runs under Statistical Process Control (SPC), checking core tensile metrics, zinc mass, and blade dimensions.
04. Custom Packaging & Logistics: Customized ODM labelling, anti-corrosion VCI packaging, and optimized shipping configurations.
Custom containment barrier designs engineered for high-security facilities, maritime zones, and national infrastructure.
For border security, we deliver high-density triple-layer concertina wire systems. Using heavy-duty CBT-65 coils, these barriers resist standard manual tools and withstand severe weather without degradation.
Marine environments require salt-spray resistance. We supply Grade 316 stainless steel CBT-60 concertina razor wire, engineered to withstand saltwater exposure while retaining tensile strength.
Prisons require maximum physical deterrence. We install dense, multi-tier CBT assemblies with heavy-duty structural steel brackets, designed to prevent climbing and resist intrusion attempts.
Challenge: An OEM tier-1 client required custom high-strength fasteners to withstand engine vibration.
Sinsun Solution: Redesigned components using custom alloys, which achieved a 15% weight reduction and passed a 2,000-hour vibration test.
Challenge: Marine infrastructure fasteners required reliable performance under high-salinity conditions.
Sinsun Solution: Developed duplex stainless steel fasteners with specialized passivation coatings, resulting in zero failures over years of service.
Technical guidance regarding specifications, ordering processes, and shipping logistics.
The difference lies in blade length and profile. CBT-65 features a blade length of 65mm ± 2mm, which provides a stronger visual and physical deterrent compared to the smaller 22mm blades of the BTO-22. The extended blade length of the CBT series is designed for high-security applications like military zones and borders.
We use high-zinc hot-dip galvanized steel sheet (Z275, 275g/m² coating weight) or premium grade 304/316 stainless steel. Our coatings are tested to survive over 1,000 hours in salt-spray test environments without structural rust formation, meeting ASTM and EN international standards.
Yes. We offer fully integrated ODM and OEM packaging support. Operating from our 12,000 square meter warehouse, we supply custom cartons, protective wraps, 3D design packaging previews, and shipping labels, ensuring products arrive ready for distribution.
For standard specifications, production and delivery configurations take between 4 to 6 weeks. Our ERP tracking and logistics coordination allow us to maintain an on-time shipment rate of over 99% across our global distribution network.
