Sinsun Hardware, established in 2006, is a leading manufacturer and global supplier of high-quality fasteners and architectural steel components. As Northern China's largest producer of Self-Tapping Screws, we operate from a gigantic 30,000 sqm integrated facility that includes modern production zones, a 12,000 sqm smart warehouse (18,000+ pallet capacity), and multi-language customer support centres. Our yearly supply of over 8,500 containers consistently services key global markets such as the Middle East, Southeast Asia, South America, and Russia.
Our production prowess is driven by German-imported machinery, precision Taiwanese technology, and a dependable staff of trained specialists. We offer over 20,000 SKUs of nails, screws, wires, and rivets, each undergoing 12+ stringent quality checks to assure outstanding polish (Ra ≤ 0.4μm), corrosion resistance (1,000+ hours salt spray), dimensional accuracy (±0.02mm), high strength (1,000+ MPa), and consistent hardness (HRC 28-32).

Welded wire mesh fencing has transitioned from basic rural boundaries to highly engineered physical security systems. Rapid urbanization, strict cross-border infrastructure initiatives, and strict safety guidelines drive global demand for high-strength mesh frameworks.
Modern high-security installations, such as correctional facilities, electrical substations, nuclear power plants, and airports, mandate high-gauge welded wire mesh barriers (such as the standard 358 mesh style). These specifications prioritize anti-climb, anti-cut profiles that resist high-impact structural forces.
For large-scale farming environments, wire mesh fencing acts as the primary barrier against predators. Our factories construct customized poultry wires, structural field fences, and heavy-duty livestock panels designed to withstand soil acidity, humidity, and physical collisions without joint displacement.
Safety regulations within civil construction require high-visibility, temporary, and permanent welded wire mesh enclosures. By integrating corrosion-resistant coatings, structural elements hold up against concrete loads and aggressive industrial zone atmospheres.
Not all welded wire mesh products are created equal. A factory's credibility is defined by raw material control, weld shear value consistency, and the uniform application of surface coatings. Sinsun Hardware employs structural testing methods to optimize shear integrity across all coordinate weld points.
| Performance Param | Industry Standard Requirement | Sinsun Hardware Premium Line | Typical Applications |
|---|---|---|---|
| Raw Material Source | Commercial Grade Mild Steel Wire | Xingtai / Ansteel Group (C1022A, Q195, Q235) | All structural grades |
| Tensile Strength | 350 - 500 MPa | High-Tensile (550 - 850 MPa options) | High Security, Anti-Crash barriers |
| Weld Shear Strength | Min. 50% of the wire breaking strength | Exceeds 75% via multi-station resistance welder | Heavy-Duty industrial partitions |
| Galvanization Density | 40 - 60 g/m² | Hot-Dipped Galvanized up to 275 - 366 g/m² | Offshore coastal infrastructure, humid zones |
| Polymer Coating | Thin PVC Powder Spraying | Thermosetting PVC/PE Fluidized Bed Coating (Ra ≤ 0.4μm) | Suburban developments, commercial parks |
| Salt Spray Life | 240 - 480 Hours | 1,000+ Hours (No red rust propagation) | Harshest chemical processing plants |
The manufacturing paradigms for welded wire mesh factories are shifting toward digitization and smart production management. Sinsun's continuous investment targets three core developmental vectors:
Integrating automatic closed-loop weld voltage controls ensures that each vertical and horizontal intersection is welded with optimal current and pressure. This minimizes heat-affected zones (HAZ) and preserves structural properties at the steel core.
We are moving past traditional galvanization by adding graphene-enhanced epoxy primers beneath the weather-resistant topcoat layer. This double-layer system blocks moisture ingress even if the fence suffers mechanical damage during installation.
Modern construction projects require varied line-wire pitches. Our CNC machinery allows rapid program changes, making it straightforward to manufacture custom mesh sizes on demand for complex engineering drawings.
From Sinsun founding in 2006, Sinsun has grown into a leading Chinese fastener and wire component manufacturer. Explore our journey of expansion, from establishing exports in 2012 and integrating German technology in 2018, to achieving a 36,000-ton annual output and adding advanced heat treatment lines by 2025.
At SINSUN, our quality control begins at the source. We start with premium raw materials from XING TAI Steel, then perform in-house spheroidizing annealing and precision wire drawing in our own plant. This end-to-end control, supported by our advanced drawing machines and gas-fired furnaces, ensures superior microstructure, consistency, and performance in every fastener and mesh product we produce.
At SINSUN, we combine German-engineered multi-station cold heading machines with precision Taiwanese production technology. Our specialized processes, including tail-gripping for drill screws, ensure every fastener is manufactured with utmost accuracy and consistency in our state-of-the-art production facility.
SINSUN operates four dedicated heat treatment lines, allowing for precise and controlled processing time to achieve consistent hardness and enhanced product durability. This in-house capacity ensures both exceptional fastener quality and reliable delivery schedules. See our advanced heat treatment systems in action, supporting our end-to-end manufacturing control.
