We operate as a core strategic partner to engineering contractors, industrial developers, and international procurement networks. Our annual supply capacity exceeds 8,500 shipping containers, ensuring timely, reliable raw material and product availability across key global zones, including the Middle East, Southeast Asia, South America, and Russia.
Get a Quick QuoteFor global security, infrastructure, and heavy industrial site developers, structural integrity is paramount. Diamond mesh chain link fence nets form the backbone of modern civil fencing. To provide maximum durability, our ODM production processes combine chemical engineering with precision mechanical wire fabrication.
Our diamond mesh starts with low-carbon steel wire rods sourced from industry leaders like Xingtai Iron & Steel. These raw materials undergo spheroidizing annealing to relieve stress and establish a uniform metal microstructure. This ensures the wire achieves a tensile strength of 350-550 N/mm², providing structural resilience against deformation under mechanical impact or high-load conditions.
To withstand environmental wear, our wires are treated with hot-dip galvanization or high-adhesion PVC/PE coatings. Heavy zinc coatings reach up to 290g/m² (conforming to EN 10244-2 Class A), resisting oxidation. For harsh industrial zones, our thermal-fusion polymer coatings (complying with ASTM F668 Class 2b standards) prevent micro-cracking and moisture ingress, extending service life.
The terminal ends of our diamond mesh are custom-configured depending on the application. We offer Knuckle-Knuckle (KK) closures to eliminate sharp edges for residential and public spaces, and Twist-Twist (TT) or Knuckle-Twist (KT) closures for high-security applications like military installations or airports. This customizability ensures optimal safety and quick, trouble-free installation.
Unlike factories that source secondary wire, Sinsun Hardware operates a vertically integrated production line. We begin with raw steel wire rods, utilizing in-house spheroidizing annealing and precision wire drawing. This control allows us to calibrate exact wire gauges (from 6 to 18 gauge) to meet specific architectural and security standards.
Our manufacturing plant is equipped with German-imported multi-station cold forming machines and precision Taiwanese processing lines. In 2025, we integrated four state-of-the-art gas-fired heat treatment lines to optimize the mechanical stability of our wire products. Every production run undergoes twelve quality checks, testing for dimensional tolerances (±0.02mm), tensile strength, and zinc adhesion.
Our technical team reviews client requirements (mesh apertures, wire gauge, coatings, selvage types) to develop precise 3D rendering designs.
Manufacturing is carried out using automated mesh looms and high-precision machinery, with in-line testing for zinc coating weight and tensile load capacity.
We leverage our 12,000㎡ smart warehouse for consolidated packaging, custom labeling, and rapid port dispatch to minimize transit times.
Sinsun established its foundational production base in Northern China, focusing on developing specialized precision fasteners and wire fabrication capabilities.
Sinsun founded its dedicated Export Department, expanding operations beyond domestic supply lines to serve key markets in the Middle East and Southeast Asia.
We integrated four advanced spheroidizing furnaces and wire drawing systems. This vertical integration ensured control over raw materials, ensuring wire gauge and metallurgical consistency.
Imported German multi-station cold heading machinery and upgraded Taiwan-engineered high-speed mesh and drill tail machines to increase production capacity.
Annual manufacturing output scaled to 36,000 tons, exporting over 1,100 high-capacity containers globally, cementing Sinsun's position as a reliable Tier-1 B2B supplier.
Implemented a 1,200㎡ quick-ship regional warehouse containing high-frequency SKUs to minimize processing delays for urgent industrial orders.
Installed four state-of-the-art continuous atmosphere heat treatment lines. This upgrade guarantees optimal structural uniformity, tensile strength, and coating adhesion across all product lines.
High-security transportation hubs require fencing systems that resist corrosion and mechanical stress. Our custom diamond mesh chain link fence nets, featuring KT selvages and polymer coatings, provide cost-effective perimeter protection that stands up to environmental exposure.
Using high-tensile carbon steel wires, our diamond mesh net systems are widely deployed for mountain slope stabilization and rockfall protection. The high tensile strength (up to 1,000+ MPa) and flexible structure of the diamond weave absorb heavy kinetic energy, protecting critical transportation corridors.
In environments like offshore wind farms, solar fields, and electrical substations, standard wire mesh can degrade rapidly. Sinsun's heavy-duty hot-dip galvanized and PVC-coated wire meshes are engineered to withstand prolonged UV exposure and coastal humidity.
For heavy industrial environments, we recommend a 9-gauge or 6-gauge wire with a mesh aperture of 50mm x 50mm to provide robust impact resistance. In coastal applications with high salinity, we advise using thermally fused PVC/PE coated wire over a galvanized steel core. The polymer layer acts as a barrier against saltwater corrosion, while the hot-dip galvanized core prevents rust creep even if the coating is damaged.
Standard extruded PVC coatings form a loose sleeve over the core wire, which can trap moisture underneath if the sleeve is torn. In contrast, thermal-fusion bonding uses a high-performance adhesive primer that chemically binds the polymer directly to the galvanized wire. This prevents internal moisture migration, ensuring the coating resists peeling and cracking during temperature fluctuations.
We maintain direct partnerships with leading domestic steel producers, such as Xingtai Iron & Steel. This allows us to source raw material wire rods with consistent chemical composition (controlled carbon, sulfur, and phosphorus content). Controlling raw material quality allows us to prevent issues like brittle failures and uneven drawing, ensuring consistent mechanical performance throughout long fence installations.
Knuckled-knuckled (KK) selvage features rounded ends, reducing snagging risks and making it easier to handle during installation in public spaces. Twist-twist (TT) selvage, where the wire ends are twisted together into sharp points, increases security by acting as an additional barrier against climbing. TT selvage is commonly used in high-security facilities like military zones, airports, and prisons.
We utilize modern, automated weaving looms that maintain constant wire tension during production, preventing mesh distortion. Additionally, our quality control team checks wire diameter tolerances (±0.02mm) and aperture uniformity at regular intervals. This ensures that rolls align during installation, reducing labor costs and improving structural alignment on site.
