Explore our foundational range of certified global hardware exports, engineered with German machinery and Taiwanese manufacturing accuracy.
Sinsun Hardware is a premier manufacturer and global supplier of high-precision industrial fasteners. Working out of a massive 30,000 sqm modern manufacturing facility, we manage Northern China's largest output of specialty self-tapping screws and wire staples. With our state-of-the-art 12,000 sqm smart warehouse capable of holding over 18,000 pallets, we supply more than 8,500 containers annually to partners across the Middle East, Southeast Asia, South America, and Russia.
Our production combines German-engineered multi-station cold heading systems with precision Taiwanese tooling. With over 20,000 SKUs in our portfolio, we enforce 12+ strict quality checks to guarantee incredible surface finish (Ra ≤ 0.4μm), corrosion resistance (exceeding 1,000+ hours in salt spray testing), high dimensional tolerance (±0.02mm), high tensile strength (1,000+ MPa), and a balanced hardness index (HRC 28-32).

The 10J staple series represents a benchmark in pneumatic and manual fastening configurations. Standardized with an outer crown width of 11.2mm, a wire thickness of 1.2mm, and wire width of 0.6mm (often classified under the 20-gauge specification), the 10J configuration strikes an ideal balance between shear resistance and material penetration. Sinsun Hardware manufactures these tools utilizing premium high-tensile carbon steel wire sourced directly from Ansteel and Xingtai Steel. Spheroidizing annealing operations conducted inside our own facility ensure that the wire possesses consistent internal microstructure prior to cold-drawing, achieving a tensile strength profile that exceeds 1,000 MPa.
To operate reliably in high-frequency pneumatic staplers, each staple strip must maintain rigid alignment without premature fragmentation. Our production lines combine precise wire alignment, automated cold stamping, and synthetic resin bonding agent applications. This ensures that the staple legs remain perfectly parallel and enter hard woods or composite boards without bending or buckling.
Colored coated 10J staples serve dual purposes: visual distinction (for inventory control, sorting, branding, and color-matching with target materials) and advanced corrosion protection. The color coating process applied at Sinsun involves a multi-layer protective coating system: first, a galvanized zinc layer is electro-deposited onto the steel wire, followed by a chemical conversion film, and finalized with a high-performance polymer/epoxy coating. This compound layer creates a barrier that isolates the iron core from oxygen, moisture, and acid compounds.
A primary challenge with color-coated fasteners is peeling. High-pressure shearing by pneumatic stapler driver blades can peel off lower-quality coatings. Sinsun resolves this by utilizing thermo-setting polymer resins that chemically cross-link with the zinc-plated base. This ensures the coating withstands mechanical impact and remains intact, maintaining its anti-corrosive properties and color even when driven into dense materials.
The global demand for color-coated 10J staples spans across automotive interior assembly, furniture upholstery, acoustic panel installation, and retail packaging. North American and European manufacturers increasingly require color-matched staples to hide mechanical connection points on wood paneling, automotive leather, and high-end display cases. In South America and Southeast Asia, the focus is on moisture protection, where colored coatings serve as an effective defense against rust in humid climates.
Procurement teams are shifting away from generic distributors toward vertically integrated OEM manufacturers. Working directly with Sinsun allows businesses to customize wire diameters, crown widths, and chemical coating compositions to meet specific local regulations, such as RoHS and REACH compliance.
Colored staples are matched directly to fabrics and leathers, concealing mechanical joints. The polymer coating also protects against sweat and chemical cleaning agents.
Used to secure fabric to plastic backings in door panels and headliners. The high vibration resistance of our 10J staples prevents component shifting over time.
Color coding simplifies inventory management in logistics hubs. Green, red, or yellow staples indicate batch numbers, export destinations, or quality levels.
