Operationalized four computer-controlled heat treatment lines and completed our 12,000 sqm smart logistics warehouse. This setup supports a dynamic capacity of 18,000+ pallets to ensure stable, on-time B2B supply chains.
High-durability fencing relies on strict control over raw steel chemistry and processing. At Sinsun, we ensure reliability by managing the entire manufacturing process in-house.
We source carbon steel wire rod directly from Xingtai Iron & Steel, specializing in grades like C1022A and high-carbon variants. This provides a clean chemistry profile with minimal impurities, ensuring consistent tensile behavior during drawing.
Our computer-controlled gas furnaces manage heat cycles to optimize the steel's internal microstructure. This annealing step relieves stress, prevents cracking, and ensures consistent ductility for weaving and forming operations.
We draw wire through precision tungsten carbide dies to reduce diameters while increasing yield strength. This process ensures consistent tolerances, high tensile strength, and a smooth surface finish ready for zinc coating.
Agricultural and livestock containment requires fencing that can withstand heavy impacts, resist harsh weather, and deliver a long service life. As a specialized manufacturer in China, Sinsun produces fencing systems engineered to meet these demands across global farming operations.
Our hinge joint fence is designed for flexibility on uneven terrain. The wrapped wire junctions act as hinges, flexing under impact from heavy animals like cattle, sheep, or goats, and then springing back into shape. This flexibility prevents permanent deformation and absorbs impact energy, reducing wire breakage.
For high-pressure animal containment, our fixed knot fence utilizes separate vertical stay wires wrapped securely with a solid lock knot. Constructed from high-tensile carbon steel wire, this fence remains rigid and upright with minimal stretching, requiring fewer line posts and reducing installation costs.
We also produce high-density welded wire mesh for poultry, poultry cages, and small livestock. Additionally, our industrial barbed wire lines generate protective strands designed to deter predators and secure outer perimeter boundaries.
We utilize automated weaving machines that ensure uniform spacing, square alignment, and secure knot wraps. Computerized tensioning controls prevent slack lines, ensuring consistent dimensions across large-volume production runs.
By operating our own continuous hot-dip galvanizing lines, we ensure uniform zinc adhesion across the wire. This complete control over coating thickness provides predictable corrosion resistance, even in humid, coastal, or high-ammonia farm environments.
Our 12,000 sqm smart warehouse manages inventory levels for standard mesh configurations. With automated sorting and direct container loading, we minimize lead times for both bulk orders and custom shipments.
Agricultural boundaries face different physical and environmental challenges depending on the region. Sinsun works with global distributors and farm managers to provide tailored fencing solutions for specific local climates and applications.
In expansive rangelands, temperature fluctuations and wind-driven abrasive dust can accelerate wear. We supply high-tensile fixed knot fencing that spans long distances with minimal post requirements, utilizing Class 3 zinc coatings to maintain structural integrity in hot, dry environments.
Confined spaces with high concentration of manure and moisture generate corrosive ammonia gas. For these environments, we supply wire mesh coated with a Zinc-5% Aluminum alloy (Galfan) or thick PVC. These coatings resist chemical corrosion, extending the fence's life inside barns and feedlots.
Preventing intrusion by invasive species requires high puncture resistance. Our fixed knot fences feature smaller bottom mesh spacing to prevent burrowing and small animal entry, while the high-tensile wire resists impact from larger wildlife like wild boars or deer.
Securing agricultural perimeters requires more than just high-quality wire mesh. Posts, bracing, tensioners, and structural fasteners are all essential parts of a durable fence. Sinsun's capability as both a wire and fastener manufacturer allows us to supply complete installation systems.
We provide a comprehensive range of structural lag screws, concrete fasteners, washers, and specialized roofing nails. This single-source supply simplifies procurement by ensuring all components are engineered to the same metallurgical and corrosion-resistance standards.
For a tier-1 automotive supplier, we redesigned structural fasteners using a custom alloy and specialized thread profile. The components achieved a 15% weight reduction while successfully passing 2,000-hour vibration testing.
We supplied high-diameter fasteners and structural components with specialized passivation coatings for marine environments. The duplex stainless-steel grade exceeded client specifications, showing no failure in salt-fog testing.
We welcome international clients, supply chain auditors, and engineering teams to visit our facility in Tianjin, China. These visits provide first-hand views of our production processes, raw material yards, automated weaving lines, and quality control laboratories.
Sinsun actively participates in global exhibitions, including agricultural technology and hardware trade shows in Europe, Russia, South America, and the Middle East. These events allow us to connect with B2B partners, share technical innovations, and establish long-term distribution agreements.
Our minimum order quantities are optimized for standard container shipments to ensure cost-effective logistics. For standard dimensions of hinge joint and fixed knot fencing, the MOQ typically ranges from 200 to 500 rolls. For custom dimensions, wire gauges, or special alloy coatings (like Galfan), the MOQ depends on the production run requirements. Contact our sales engineering team for detailed configurations.
All Sinsun agricultural fencing wires are manufactured and tested to meet international standards. We comply with ASTM A116 (for metallic-coated steel woven wire fence), ASTM A121 (for zinc-coated carbon steel barbed wire), BS EN 10223-5 (for steel wire and wire products for fencing), and ISO 9001 quality management guidelines. We supply material mill test certificates (MTC) and zinc-coating weight validations with every shipment.
We use high-grade hot-dip galvanized wire with Class 1 (approx. 90 g/m²) or Class 3 (approx. 240–270 g/m²) zinc coatings. For highly corrosive environments like coastal regions or high-ammonia livestock housing, we offer Zn-5Al-MM (zinc-aluminum mischmetal alloy) coatings or PVC finishes. These materials undergo salt spray testing up to 1000+ hours to ensure long-term oxidation resistance.
Yes. Our 12,000 sqm packaging warehouse supports full OEM and ODM services. We design and print custom retail labels, barcode configurations, and pallet wrapping styles. Our design team can also provide 3D digital renders of custom layouts for packaging approval prior to manufacturing.
For standard mesh configurations, our lead time typically ranges from 4 to 6 weeks. For custom specifications, proprietary alloy coatings, or large multi-container contracts, lead times are determined upon order placement. Sinsun's integrated production and ERP logistics planning ensure we maintain over 99% on-time delivery for global shipments.
