Unlike conventional double-strand twisted designs, Single-Strand Barbed Wire (often referred to as mono-filament barbed wire) is engineered from a singular, high-tensile core wire. This design utilizes advanced metallurgy to supply equal structural resistance while minimizing overall weight, facilitating longer post spans and lowering freight costs.
By using a single solid core, the line wire maintains a much tighter structural yield. This prevents sag over years of deployment under extreme temperatures and heavy structural loads. The barbs are dynamically coiled around this core using high-speed precision automated machinery to prevent slippage and preserve consistent protection intervals.
For large-scale agricultural operations, border protection, and industrial perimeters, single-strand configurations offer high cost-efficiency and direct structural compatibility with automated tensioning systems.
Precision metallurgy meets global certification requirements to deliver predictable structural reliability.
Our single-strand barbed wire conforms fully to ASTM A121 (Standard Specification for Metallic-Coated Carbon Steel Barbed Wire) and EN 10223-4 (Steel Wire and Wire Products for Fencing). This guarantees that parameters like tensile strength limits and wire tolerances are verified by certified testing.
Equipped to withstand corrosive soils and coastal sea spray. We offer customized zinc coating weights, from commercial grade (60g/m²) to Class 3 heavy galvanization (240g/m²), as well as premium Zn-5%Al-MM (Galfan) coatings that extend protective lifespans threefold.
By utilizing raw materials with optimized carbon fractions (C1006 - C1008 structural steel, or C82B for high-tension lines), Sinsun’s single-strand wire achieves a high tensile strength rating of 1,000 to 1,250 MPa, making it highly resistant to cutting or mechanical deformation.
Established in 2006, Sinsun Hardware has grown into a leading developer and global supplier of industrial fasteners and wire products. Operating as one of Northern China’s largest integrated plants, our infrastructure handles everything from initial wire drawing to final heat treatment and protective surface finishes.
Our 30,000 square meter facility features modern production zones, a 12,000 square meter smart warehouse with an 18,000+ pallet capacity, and multi-language customer support teams. Sinsun ships over 8,500 containers annually to clients across the Middle East, Southeast Asia, South America, and Russia, providing consistent quality and reliable delivery timelines.

Explore our history of growth, starting with our founding in 2006, expanding exports in 2012, adopting German technology in 2018, and scaling to a 36,000-ton annual output by 2025.
Sinsun Hardware was founded with a focus on cold forging technology and high-volume carbon steel wire processing.
We built dedicated global shipping and document handling teams, expanding operations into Russia, the Middle East, and South America.
We upgraded our production line with imported multi-station cold heading machinery and precision Taiwanese wire-drawing technologies.
We integrated our smart warehouse systems and expanded heat treatment lines to reach a capacity of 36,000 tons annually.
Northern China's industrial infrastructure allows Sinsun to optimize quality, costs, and lead times.
We source our steel rods exclusively from top domestic steel producers like Xingtai Steel and Ansteel Group. Access to these high-grade, uniform steel batches allows us to prevent material failures and maintain consistent performance throughout production.
Sinsun manages the entire production cycle. In-house spheroidizing annealing, precision drawing, and custom thermal treatments ensure that every product meets strict tolerances and achieves excellent structural yield and fatigue resistance.
Our 12,000 square meter smart warehouse handles automated sorting at rates of over 3,000 cartons per hour. Located near major shipping hubs, our facility enables direct container loading to support reliable transit times for international projects.
Sinsun supports global installation requirements by adapting single-strand barbed wire designs to regional climates and regulations. For projects in high-humidity agricultural regions or coastal areas, we adjust zinc coating weights up to 275g/m² to prevent early corrosion.
Our engineering support includes full regulatory compliance, providing complete material certificates, chemical analysis sheets, and salt spray test results. This documentation helps streamline custom clearances and meets the safety requirements of local infrastructure projects.
Additionally, we work closely with engineering design firms to offer detailed advice on installation tension, post spacing, and integration with dynamic security monitoring systems.

Understanding how single-strand barbed wire adapts to different environments and looking at next-generation material innovations.
Often deployed across expansive agricultural boundaries in the Americas and Australia. Single-strand wire works well with mechanized payout systems, allowing teams to install miles of secure line wire quickly while keeping material costs down.
Typically used to support chain-link or welded mesh fences around infrastructure hubs, storage facilities, and logistics centers. Using a high-tensile single line wire helps prevent cutting and resists deformation under physical loads.
The industry is moving toward high-tensile, low-weight steel alloys and advanced zinc-aluminum-magnesium coatings. These new materials help extend service lives and reduce overall wire weight to lower transportation costs.

Answers to common technical and procurement questions from distributors and engineering contractors.
Single-strand barbed wire uses one high-tensile core wire, whereas double-strand wire twists two milder steel wires together. Single-strand designs provide high tensile strength with lower weight per meter, reducing sag and letting you set posts further apart. Double-strand wire is heavier but offers higher physical visibility along boundaries.
Thicker core wires (such as 3.0mm) increase the force required to cut or bend the wire, boosting security. They also carry a thicker galvanized zinc layer, which extends the service life in wet, acidic, or coastal environments compared to thinner gauges.
For coastal applications, we recommend Class 3 hot-dip galvanization (minimum 240g/m² coating weight) or our Zn-5%Al-MM (Galfan) alloy. The addition of aluminum to the coating provides improved protection against salt spray corrosion, helping prevent premature red rust.
We offer customization across several specifications, including wire gauges, barb counts (2-point vs 4-point), barb spacing (from 75mm to 150mm), coil lengths, and protective coatings. We also provide custom labels, 3D packaging designs, and wooden carrier options for easier transport.
Our standard manufacturing lead time is 4 to 6 weeks, depending on order size and custom finishing options. We offer flexible MOQs for project-based trials and prototype evaluations. Please contact our support team to discuss your specific needs.
