In modern industrial agriculture and large-scale structural landscaping, Galvanized Chicken Wire Mesh (historically recognized as hexagonal wire netting) acts as a baseline protective component. Procurement managers across Europe, South America, the Middle East, and North America face a dual challenge: acquiring meshes that survive corrosive regional environments while maintaining tensile integrity. Driven by urbanization, modern poultry farm automation, and environmental containment designs, the global demand has transitioned from basic wire fencing to highly customized, double-twisted, hot-dip galvanized specifications.
As an experienced ODM (Original Design Manufacturer) and strategic exporter, we map design challenges directly to wire metallurgy. Modern projects demand specific zinc coating grades—whether utilizing Galvanized Before Weaving (GBW) for cost-effective agricultural barriers or Galvanized After Weaving (GAW) to guarantee zero raw iron exposure at twist points. Our manufacturing processes directly accommodate variations in wire diameter (ranging from 0.5 mm up to heavy-duty 2.0 mm structural variants) and aperture specifications configured to survive mechanical stress and corrosive degradation.
"Structural failures in agricultural barriers cost international distribution networks millions annually. The solution lies in choosing manufacturers who control the chemical composition of steel wires and apply strict mechanical stress thresholds."

Established in 2006, Sinsun Hardware operates as Northern China’s premier integrated manufacturing hub, processing raw wire inputs into structural-grade fastener systems and industrial meshes. Covering a 30,000 sqm modern manufacturing zone coupled with a 12,000 sqm smart warehouse (with over 18,000 pallet capacity), we actively manage high-volume global distribution pipelines. Exporting more than 8,500 shipping containers annually across the Middle East, Southeast Asia, South America, and Eastern Europe, we coordinate complex supply chains from raw steel selection to final transport.
Our raw material strategy utilizes premium steel grades supplied directly from XING TAI Steel and Ansteel Group. We carry out in-house spheroidizing annealing and precision wire drawing processes. Sinsun manages four dedicated in-house heat treatment lines (delivering 20-ton daily capacity) and cold-forging multi-station machinery to ensure structural fasteners and mesh wires maintain dimensional stability, low tolerances (±0.02mm), and targeted surface finishes (Ra ≤ 0.4μm).
Combining automated wire processing systems with structural-grade metallurgy to achieve consistency and high dimensional precision.
We start with premium low-carbon wire rod from Xingtai Steel, refining it in gas-fired spheroidizing annealing furnaces to ensure uniform microstructure and ductility before wire drawing.
Utilizing high-speed automated weaving machines, we implement tight, uniform double-twisted structures. This prevents unravelling when the mesh is cut, providing structural safety in agricultural enclosures.
By coating the woven structure after fabrication, we eliminate bare iron weld joints or stress points. This ensures complete coverage, offering maximum resistance to environmental corrosion.
Applying high-purity zinc coatings ensures long-term protection. Certified testing verifies that our GAW and PVC-coated wire mesh options survive corrosive environments, providing reliable service life.
A structured, quality-controlled collaborative workflow that transforms technical requirements into targeted product shipments.
We analyze wire tensile strengths, mesh size requirements, and zinc coating masses relative to your regional climate, soil conditions, and structural requirements.
Our lab develops pre-production samples, running tensile strain, zinc layer consistency, and salt spray testing to confirm durability against environmental corrosion.
With an annual output reaching 36,000 tons, we schedule manufacturing runs with real-time quality checks and export coordination directly through Tianjin port.
Choosing the correct galvanizing method is key to balancing project budgets and product service life. Galvanized Before Weaving (GBW) draws and galvanizes individual steel wires before processing them on hexagonal weaving looms. While this keeps production costs low, the twisting action can micro-fracture the protective zinc coating. This leaves tiny areas of raw steel exposed to moisture and oxygen, which can lead to early rust formation at the joints.
To address this, Sinsun offers Galvanized After Weaving (GAW) mesh. We weave raw steel wire first, then pass the completed mesh structure through a molten zinc bath. This process seals every joint and twist point in a thick protective layer, providing enhanced resistance to rust in wet or coastal environments.
For demanding applications, we offer a specialized PVC-coated line. Applying an outer polymer sleeve over hot-dip galvanized wire adds double barrier protection against harsh chemical cleaners and acids, making it a reliable solution for agricultural use.
Every shipment undergoes structural and chemical verification in our laboratory, ensuring compliance with international project standards.
We run chemical assays and mechanical tests on every incoming coil of steel rod from Xingtai Steel, verifying carbon content, tensile limits, and microstructural uniformity before drawing.
We perform destructive tensile tests on wire samples from each production run, ensuring the wire retains high flexibility while maintaining strength specifications.
Using weight-stripping test methods, we verify the absolute mass of the zinc coating per square meter, ensuring it matches the specified design requirements.

Clear answers to common questions about specifications, manufacturing processes, and international shipping options.
GBW (Galvanized Before Weaving) uses pre-galvanized wires, which can leave small cracks in the zinc layer at the twist points during weaving. GAW (Galvanized After Weaving) is woven first, then hot-dipped in zinc, sealing all joint areas to provide maximum protection against rust.
We use automated chemical stripping and magnetic thickness testing to verify the zinc layer weight. This ensures we meet your specified target range, whether you require a light 40g/m² coating or a heavy-duty 240g/m² marine-grade finish.
Yes. Our ODM capabilities allow us to adjust wire diameters from 0.5mm up to 2.0mm and modify hexagonal mesh openings from 3/8 inch to 3 inches to suit your specific application.
Production cycles usually run 4 to 6 weeks, depending on order size and custom specifications. We coordinate shipping directly from Tianjin port, providing full tracking documentation from our smart warehouse to your delivery address.
We provide full material test reports (MTR), mill test certificates, and detail dimensions, along with salt spray test certification for high-durability projects.
We offer customized packaging, including moisture-proof kraft wrapping, protective shrink film, and reinforced wooden pallets, to prevent damage during long-distance ocean transport.
