Precision-crafted hardware solutions engineered for high performance, strength, and corrosion resistance.
In the commercial upholstery, automotive trim, and packaging manufacturing sectors, the selection of the correct fastening mechanism is a critical design choice. The 22 Gauge 71 Series Staple represents the engineering standard for precision fine-wire anchoring. Characterized by its 9mm (or 3/8 inch) crown width and wire thickness profile of approximately 0.71mm, these fasteners offer the ideal ratio of holding power to minimal substrate visibility.
From an engineering perspective, the 22-gauge profile balances structural strength with structural discretion. Large fasteners risk fracturing delicate wood frames or tearing thin leather linings, whereas the 71 Series penetrates smoothly without splitting fibers, remaining securely anchored in the grain thanks to its high-quality chisel point design.
OEM suppliers and factories must ensure precise dimensional accuracy. Standard tolerances cannot exceed ±0.02mm, as variations would cause jams in professional-grade pneumatic staplers operating at rates over 120 cycles per minute. Achieving this level of precision requires advanced wire drawing processes and high-grade raw carbon steel wire.
Operating a massive 30,000 square meter integrated facility, Sinsun Hardware has delivered certified fastener excellence since 2006.
Sinsun Hardware stands as a key partner for global distributors and industrial brands. Our production combines German multi-station cold heading machinery with precision Taiwanese technology. Every batch of 22 Gauge 71 Series Staples undergoes a minimum of 12 strict quality checks. This ensures high dimensional accuracy (±0.02mm), high tensile strength (exceeding 1,000 MPa), and clean surfaces (Ra ≤ 0.4μm) that prevent feeder jams and ensure reliable tool cycling.
Unlike basic trading entities, Sinsun handles the entire manufacturing process in-house. Starting with premium raw material rod stock from XING TAI Steel, we perform spheroidizing annealing and precision wire drawing within our own plant. Our four advanced heat treatment lines, upgraded in 2025, guarantee consistent metallurgical hardness (HRC 28-32) and exceptional resistance to bending during high-pressure installation.
How our localized supply chain, advanced technology, and raw material control benefit international buyers.
We source raw carbon steel directly from Xingtai Steel, processing it in our spheroidizing furnaces. By managing the wire drawing and heat treatment stages in-house, we eliminate intermediate vendor markups and maintain consistent mechanical properties.
Whether electro-galvanized, hot-dip galvanized, or stainless steel (Grade 304/316), our proprietary chemical passivations provide over 1,000 hours of salt spray exposure test resistance. This ensures reliable performance in humid and coastal environments.
We offer tailored packaging configurations to suit different retail and industrial preferences. From custom-branded inner boxes and polybags to heavy-duty bulk shipping cartons, our 12,000 sqm warehouse supports flexible shipping preparation and private label packaging.
Analyzing technology developments, market demands, and automated updates within the industrial fastening sector.
The global industrial staple market is transitioning from basic commodity components to specialized, high-performance fasteners. With the rise of automated assembly lines in the furniture and automotive sectors, the performance consistency of 22 Gauge staples has become critical. Automated robotic staplers require precise alignment and high shear strength to avoid tool failures and prevent production downtime.
Sustainability is also driving changes in surface treatment chemistry. Heavy-duty zinc-plating processes are moving away from traditional hexavalent chromium (CrVI) toward eco-friendly trivalent chromium (CrIII) and organic polymer coatings. These alternatives provide excellent rust prevention while meeting strict international environmental directives, including RoHS and REACH regulations.
Additionally, material selection is expanding to meet specific environmental demands. While galvanized carbon steel remains the standard for general indoor upholstery, marine grade 316 stainless steel and high-tensile alloy options are increasingly specified for outdoor furniture, automotive interiors, and marine applications to prevent corrosion and early failure.
Where precision 22 Gauge 71 Series staples deliver critical performance across various industries.
Used to anchor seat fabric, leatherette wrap, door trim panels, and acoustic insulation to composite substrates. The fine-gauge wire holds securely without damaging fabrics, maintaining clean aesthetics and interior durability.
Essential for securing webbing, fabric covers, dust covers, and padding to hardwood frames. The 9mm crown distributes pressure effectively across fabrics without tearing the weave, even under regular tension.
Perfect for fastening protective vapor-barrier foils, plastic films, and thin wood panel backings. These staples provide quick installation and reliable holding power in heavy-duty shipping and logistics setups.
From our founding in 2006 to a leading Chinese fastener manufacturer, explore our journey of expansion and technological upgrades.
Sinsun founded with a focus on self-tapping screw production.
Established the export department to serve global markets.
Added 4 spheroidizing furnaces for raw material processing.
Integrated German multi-station cold heading machinery.
Annual production reached 36,000 tons with 1,100 export containers.
Expanded local logistics with a 1,200 sqm ready-stock facility.

Essential parameters for international purchasing departments, industrial buyers, and wholesale distributors.
Managing a global supply chain requires strict compliance with international manufacturing standards. Professional purchasing managers rely on key parameters to assess factory capability and product quality: chemical composition verification (using raw material ladle analyses), tensile strength certifications, and zinc coating thickness measurements (measured in microns or g/m²).
Standardizing packaging is also crucial for preventing transit damage. Sinsun uses heavy-duty double-wall corrugated outer cartons, multi-layered wooden pallets, and moisture-resistant stretch film wrap. This ensures the products withstand ocean transit and warehouse handling, arriving at their destination ready for immediate distribution.
