Explore our highly-engineered industrial fastening products optimized for structural construction, manufacturing, and heavy-duty load distribution.
Galvanized steel wire serves as a critical structural component across vast global economic sectors. From supporting large-scale agricultural trellising and powering telecommunication lines to providing reinforcement for deep-sea cable armoring and heavy construction meshes, the mechanical properties of galvanized steel wire govern safety and operational longevity.
As standard-setting manufacturers, Sinsun Hardware addresses macro industrial demands by delivering optimized metallurgical microstructures. Our wire options undergo severe cold-drawing and precise thermal processing. By utilizing protective zinc barrier coatings—ranging from standard electro-galvanized finishes to heavy hot-dip coatings of up to 360g/m²—we ensure structural systems successfully resist salt-spray corrosion and high-stress loading profiles, keeping key operations running smoothly around the world.
Sinsun Hardware, established in 2006, is a leading manufacturer and global supplier of high-quality fasteners. 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).
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 we produce.
Controlled gas-fired heat treatment allows optimal carbon reorganization, yielding uniform ferrite/cementite distribution. This enhances ductility, reduces micro-cracking risk, and improves subsequent thread-rolling operations.
Utilizing high-speed German multi-station forming setups, we maintain close structural shape tolerances. This process produces high tensile wire and fastener components with precise dimensional configurations.
Advanced hot-dip technology prevents zinc layer peeling, ensuring the zinc-iron alloy layer adheres firmly to the steel wire core. This guarantees reliable performance during deep bending and installation.
