As a premier global manufacturer of perimeter security systems, we specialize in fabricating high-specification BTO-18 Razor Wire (also known as BTO-18 Concertina Wire). This specific model features an 18mm blade length, structurally engineered to deliver a formidable physical and psychological deterrent against unauthorized entry. Unlike standard barbed wire, our razor ribbon uses a rigid, high-tensile core wire wrapped mechanically with razor-sharp steel barbs, making it nearly impossible to cut or scale without specialized industrial equipment.
Why Source BTO-18 Razor Wire From Our Factory?
Our production facility implements rigorous ISO 9001 quality controls. Every coil of BTO-18 razor wire undergoes automated zinc-coating verification and tensile testing. Whether your project demands standard commercial hot-dipped galvanization or marine-grade stainless steel AISI 316 for coastal defense, our products provide unparalleled structural integrity and weathering resistance in extreme climates.
Key Features & Structural Advantages
Navigating security infrastructure requirements demands high-performance materials. Our BTO-18 security barriers are designed with several proprietary manufacturing advantages that guarantee field-tested reliable performance:
- High-Tensile Carbon Steel Core: We utilize 2.5mm heavy-gauge spring steel wire as the inner core. It boasts a tensile strength exceeding 1450 MPa, preventing sagging and ensuring the wire springs back to its original shape if compressed.
- Advanced Zinc Coating (Z40 to Z275): To combat oxidation and acid rain, our galvanized steel sheet and wire can be customized up to 275g/m² coating weight, multiplying the product’s lifespan compared to budget alternatives.
- Impeccable Barb Geometry: The 18mm short barb profile is punched precisely with sharp, uniform points spaced at 33mm intervals, providing optimal coverage and trapping efficiency along the entire fence line.
- Robust Cross-Clips Construction: By fastening adjacent loops with heavy-duty galvanized or stainless steel clips, the coil expands into a dense, sturdy three-dimensional tube that cannot be easily parted.

Application Fields & Installation Configurations
BTO-18 Razor Wire is highly versatile and seamlessly integrates into existing commercial fencing ecosystems to provide multi-layered defense. It can be installed as a standalone system or combined with high-security meshes:
- Wall Topper Upgrades: Affixed onto pre-existing brick or concrete perimeter walls via heavy-duty Y-posts or extension arms to prevent scaling.
- Chain Link & Welded Mesh Reinforcement: Fastened to the base, middle, or top of chain-link fences to eliminate tunneling and breach vulnerabilities in industrial sectors.
- Military Ground Barriers: Multiple concertina coils are stacked horizontally and vertically on top of each other to deploy quick, temporary mobilization obstacles.

Frequently Asked Questions (FAQ)
Q1: What is the exact difference between BTO-18 and BTO-22 razor wire?
A: The core difference lies in the barb length and spatial coverage. BTO-18 features an 18mm barb length and 33mm spacing, categorized as a short barb profile. BTO-22 features a 22mm barb length and 34mm spacing, making it a medium barb. BTO-18 offers excellent, dense physical prevention and is frequently specified in large-scale government procurement tenders due to its superior cost-to-performance ratio.
Q2: How many years will hot-dipped galvanized BTO-18 last in outdoor environments?
A: Lifespan depends strictly on the zinc coating specification. Our standard commercial-grade hot-dipped galvanized wire (40-60g/m²) lasts 3 to 5 years. For heavy industrial or high-humidity regions, we strongly recommend our heavy galvanized wire (240-275g/m²), which provides reliable rust protection for over 10-15 years.
Q3: Should I choose Single Coil or Cross-Type (Concertina) BTO-18?
A: Single coil razor wire runs in a simple continuous loop without clips, suitable for low-level residential security. Cross-type concertina razor wire links loops together using steel clips, expanding into an intertwined tubular matrix. For maximum perimeter defense against forced entry, cross-type concertina is always recommended.
Q4: Can your factory supply custom roll weights and provide physical samples?
A: Yes, we provide full OEM/ODM flexibility. We can customize individual coil weights from 5kg up to 15kg and adjust the loop diameter according to your technical drawings. We also offer free material samples to qualified commercial buyers and distributors for pre-qualification verification before placing bulk orders.
