Explore our extensive line of high-performance industrial fasteners manufactured to exacting global standards.
Engineered for maximum structural integrity, anti-rotation performance, and uncompromising global deployment.
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).
Navigating modern procurement requirements with vertical integration and rigorous quality assurance.
International infrastructure projects demand fasteners that resist extreme environmental stressors. Our ribbed neck carriage bolts are engineered with high tensile compliance, ensuring anti-rotation locking inside wood and structural steel interfaces without auxiliary keys.
Quality begins at the source. We utilize premier carbon and stainless steels sourced directly from top-tier mills like XING TAI Steel and Ansteel Group, executing in-house spheroidizing annealing and precision wire drawing.
Operating four dedicated heat treatment lines allows precise control over microstructures, guaranteeing consistent core hardness (HRC 28-32) and optimal fatigue resistance exceeding 50,000 cycles.
From startup to global industry leader through continuous technological innovation.
Founded in 2006, Sinsun evolved rapidly: establishing export channels in 2012, integrating German cold-heading machinery in 2018, and scaling to a 36,000-ton annual output with advanced heat treatment lines by 2025.
Over 200 German-imported multi-station cold heading machines producing 1,200+ pieces/min/machine, paired with custom packaging solutions from our 12,000 sqm smart facility, ensure 99%+ on-time global fulfillment.
Unmatched expertise, vertical integration, and dedicated engineering consultation.
High-speed cold forging and automated sorting lines yielding over 50 TEUs of direct container loading capacity daily.
Comprehensive ISO-certified testing covering salt spray resistance, torque tension, and optical dimensional verification.
Tailored ODM/OEM packaging, CAD prototyping, and special alloy coatings (Dacromet, Hot-Dip Galvanized).
Multi-language support centers providing 24/7 commercial and technical assistance across 50+ countries.
Proven performance in high-stress automotive and marine engineering environments.
