Examine our leading range of high-tensile wire products, concrete anchors, and specialized timber connection fasteners engineered for high load capacities and extreme working conditions.
In the modern manufacturing and manufacturing logistics landscape, precision mechanical fasteners serve as the core framework for complex assemblies. The Galvanized 71 Series Staples represents a benchmark in fine-wire fastening technology. Typically fabricated from a 22-gauge high-tensile steel wire profile, these staples feature a 9.0mm - 9.1mm crown width, structural thickness measuring 0.6mm, and a staple width of 0.75mm. This specialized geometry offers a high surface-area-to-weight ratio, ensuring optimized load distribution across fragile materials like textiles, multi-ply membranes, softwoods, and plastics.
The metallurgical integrity of our 71 Series Staples relies heavily on our advanced electro-galvanization and hot-dip passivated coating methods. Applying an uniform zinc layer prevents galvanic corrosion and oxidation. We process raw carbon steel wire rods through specialized drawing configurations to reach high shear thresholds, ensuring they can penetrate hardwoods or composite panels without structural failure or leg buckling.
As a leading supplier in Northern China, Sinsun Hardware combines metallurgy and mechanics to deliver high-performance staples. Our products are engineered to run smoothly in automated pneumatic systems from brands like Senco, BeA, and Bostitch without jamming, maximizing assembly line uptime.

Industrial scale and digital integration are essential to withstand global supply chain volatility. Sinsun Hardware operates a modern 30,000 square meter integrated facility that serves as the foundation of our high-volume production capabilities.
We manage our entire supply chain starting with raw material sourcing. By partnering with Xing Tai Steel, we source premium carbon steel wire rods. In-house spheroidizing annealing and precision cold wire drawing allow us to monitor material structure and grain alignment before header processing. This vertical integration protects our clients from third-party raw material fluctuations and ensures consistent quality.
Our manufacturing philosophy focuses on precision engineering, utilizing German and Taiwanese machinery to ensure consistent tolerances.
Our in-house drawing and annealing lines process raw steel wire rods, optimizing internal grain structure. This step ensures consistent tensile characteristics across all wire runs.
Multi-station cold heading systems from Germany produce clean staple tips. This sharp tip geometry reduces the force required for tool penetration, lowering pneumatic air consumption.
Four continuous, atmosphere-controlled heat treatment lines provide uniform tempering. This controlled process eliminates brittle failures and ensures proper flexibility under dynamic loads.
Advanced chemical electrodeposition provides a uniform zinc barrier. This protection layer helps prevent rust and corrosion, even in high-humidity applications.
Since 2006, Sinsun has grown from a specialized local screw factory into a diversified, multi-facility international fastener supplier.
Factory Founded: Established a specialized facility focused on self-tapping screw manufacturing to build fundamental engineering expertise.
Global Export Division: Launched our dedicated export department, supplying structural fasteners to partners worldwide.
Vertical Integration: Added four spheroidizing furnaces and integrated in-house wire drawing capabilities to control wire quality from the raw rod stage.
Machinery Upgrades: Installed multi-station cold heading machinery imported from Germany to improve production precision and tolerances.
Increased Output Capacity: Reached 36,000 tons of annual production output and exported over 1,100 containers globally.
Smart Warehousing Expansion: Expanded ready-stock storage capacity to support high-volume distribution and immediate order fulfillment.
Enhanced Heat Treatment: Added four modern heat treatment lines to increase production capacity and control over metallurgical hardness.
Sinsun's manufacturing combines advanced machinery with a robust quality assurance program.
Our processing begins with carbon steel wire coils. Using gas-fired spheroidizing furnaces, we refine the steel's internal structure. This reduces hard spots, improves cold formability, and ensures the steel remains uniform during wire drawing and shearing.
Precision wire is fed into automated cold headers, where multi-station dies form the staple crown and legs. The staple tips are cut at precise angles to create sharp points, enabling cleaner penetration into substrates and reducing tool wear on pneumatic assembly lines.
Our four heat treatment lines temper fasteners under controlled carbon potential atmospheres. This process hardens the steel to target levels without creating surface decarburization, ensuring the staple legs can resist bending when driven into hard materials.
Our 12,000 square meter warehouse operates on a smart inventory system. We provide customized OEM and ODM packaging options, including 3D design previews, custom pallet sizes, and export labeling, to ensure orders arrive safely at our clients' distribution centers.
The 71 Series fine wire staple's geometry makes it suitable for high-volume manufacturing, automotive upholstery, and construction.
Automotive tier-1 suppliers use 71 Series staples to attach interior door panels, fabrics, and structural linings to plastic frames. Our staples' consistent dimensional tolerances ensure they feed reliably in automated robotic assembly cells.
In furniture manufacturing, the 9mm wide crown secures textiles, leather, and foam padding to hardwood frames without tearing the material. The galvanized coating protects the assembly from corrosion in high-humidity climates.
Used for attaching tags, lining materials, and thin backboard panels to transport crates. The high tensile strength helps prevent leg buckling when staples are driven through softwood and thin MDF.
