Established in 2006, Sinsun Hardware is a leading manufacturer and global supplier of high-quality industrial fasteners and specialized rubber-lined hardware support systems. Operating from a state-of-the-art 30,000 m² integrated production facility, we house Northern China’s largest production base for self-tapping mechanisms and industrial pipe support systems.
With an advanced warehousing network stretching over 12,000 m² (boasting an 18,000+ pallet capacity), we ensure that global supply chains remain uninterrupted. We export over 8,500 shipping containers annually, servicing critical sectors across the Middle East, Southeast Asia, South America, and Eastern Europe.
Our production capabilities combine advanced German multi-station cold heading machinery with high-precision Taiwanese tooling technology. This ensures that the metal substrate of our rubber-lined clamps, hose clips, and structural anchors achieves a high tensile strength exceeding 1,000+ MPa and a core hardness of HRC 28-32.
To survive in aggressive industrial environments, the rubber lining is directly vulcanized onto the metallic backbone. Our chemical-grade EPDM, Neoprene, and NBR formulations offer complete galvanic isolation, noise dampening of up to 15dB, and a salt spray corrosion resistance profile exceeding 1,000+ hours without structural degradation (Ra ≤ 0.4μm).
Whether you require tailored dimensions, high-temperature silicon linings, or extreme acid-resistant compositions, our engineering team works directly with you to provide 3D CAD modeling and custom-molded prototypes within days.

Extremely abrasive mining ores wear down structural pipes rapidly. Our rubber-lined pipe support systems prevent friction-induced cracking and withstand heavy structural vibration in modern copper, gold, and lithium processing plants.
Acids, alkalis, and organic solvents cause massive corrosion on exposed steel pipes. Sinsun's chemically inert NBR and EPDM linings prevent galvanic corrosion at the clamping contact points, safeguarding piping integrity.
High-rise buildings run high-velocity fluid pipes that transmit structural acoustic noise. Our rubber linings act as isolators, damping noise propagation up to 15dB and keeping indoor environments quiet and compliant.
The continuous mist of salt spray accelerates oxidation on marine fasteners. Combined with heavy-duty phosphate or zinc-nickel plating, our rubber-lined clamps provide dual protection against corrosive marine winds.
Tracing our expansion, modernization, and advanced capabilities from 2006 to 2025.
Sinsun was founded with a singular, unwavering mission: to build Northern China's premier high-precision manufacturing base for self-tapping screws and core fastener products, establishing strict metallurgical controls from day one.
Our dedicated Export Division was established, expanding the reach of our specialized fastener components to international distributors and infrastructure projects across the Americas, Europe, and Asia.
We achieved complete vertical integration by adding four spheroidizing annealing furnaces and in-house wire drawing systems. Controlling our feedstock from the steel mills ensured flawless chemical consistency.
We upgraded our manufacturing floor with high-speed German multi-station cold heading machinery, establishing a specialized division for drill-tail and rubber-bonded structural fasteners.
Sinsun scaled output to an annual capacity of 36,000 tons, shipping over 1,100 export containers annually to top-tier global industrial supply chains.
A new 1,200 m² rapid-shipment warehouse was added to keep our most popular SKUs (including heavy-duty hose clamps and standard drywall screws) in stock for prompt, 24-hour dispatch.
We commissioned four advanced heat treatment lines, ensuring precise mechanical hardening and consistent tensile values to meet the growing demand for custom rubber-lined installations.
Different operating environments require specific elastomer chemistries. Our technical laboratory performs standard ASTM, DIN, and ISO testing on every batch to guarantee the performance parameters outlined below:
| Elastomer Type | Temperature Range | Hardness (Shore A) | Primary Industrial Benefits | Chemical Resistance |
|---|---|---|---|---|
| EPDM (Ethylene Propylene) | -40°C to +130°C | 60 ± 5 | Excellent UV, ozone, and weathering resistance. Ideal for outdoor piping. | Dilute acids, water, steam, ketones. |
| NBR (Nitrile Butadiene) | -25°C to +100°C | 65 ± 5 | Superior oil, grease, and petroleum fuel resistance. For hydraulic systems. | Hydrocarbons, oils, grease. |
| Neoprene (Chloroprene) | -35°C to +100°C | 55 ± 5 | Balanced physical properties, flame retardancy, and vibration damping. | Moderate acids, ozone, fats. |
| Silicon (High-Temp Grade) | -60°C to +200°C | 50 ± 5 | Wide thermal stability, biocompatible. Perfect for pharmaceutical & food processing. | Oxidizing chemicals, ozone. |
By sourcing raw carbon steel directly from top-tier state mills like XING TAI Steel and processing it in-house, we insulate our global clients from volatile metal and elastomer market fluctuations.
Our automated racking system houses 18,000+ pallets of finished hardware. This setup enables quick shipments, reducing transit times to key maritime ports like Tianjin and Qingdao.
We offer tailor-made commercial packaging solutions, complete with custom labels and protective crates, ensuring goods arrive in perfect condition at your local warehouse.
SINSUN products are built to comply with international regulations, including **RoHS** and **REACH**, ensuring our rubber compounds are free from hazardous chemicals. This compliance makes them safe for use in residential water systems and public facilities.
Our manufacturing processes follow **ISO 9001:2015** quality guidelines, covering material testing and dimensional checks. Every batch is traceable back to its melt log, with certificates available for every order.
Our hardware is built to meet **DIN**, **ANSI**, and **JIS** specifications, making it easy to integrate into existing global piping networks without sizing mismatches.
