Explore our high-performance product range, engineered for precision, high holding power, and extreme environmental durability across global manufacturing lines.
Within the precision-dependent sectors of industrial woodworking, furniture fabrication, and construction, the 90 Series narrow crown staple represents a critical benchmark for structural integrity and high-speed efficiency. Characterized by an 18-gauge wire thickness and a precise crown width of 5.8mm, 90 Series staples deliver superior holding power without splitting delicate woods, making them the standard choice for cabinetry backing, subflooring, drawer assembly, and trim work.
Selecting a high-tier manufacturer is essential. Inconsistencies in wire diameter, tensile strength, or collation integrity lead to frequent tool jams, increased rejection rates, and premature structural failure. Sinsun Hardware addresses these critical industry pain points by engineering 90 Staples that maintain strict dimensional stability, flawless collation alignment, and superior metallurgical tensile strength.
Our integration of vertical manufacturing ensures that every box of staples performs reliably under intense pneumatic pressure. With over 20,000 SKUs of fasteners produced, Sinsun Hardware stands as a benchmark of engineering precision for global industrial markets.
Manufactured using cold-drawn wire to control gauge consistency within a ±0.01mm tolerance. This ensures smooth passage through pneumatic magazines and nose plates.
Engineered to guide the staple straight into timber fibers or cross-grain applications, avoiding deflection and maximizing holding power.
Located in the heart of Northern China's industrial zone, Sinsun Hardware operates the largest production base for self-tapping screws and industrial wire fasteners in the region. Our facility is engineered on a Smart Manufacturing foundation. By utilizing raw materials sourced directly from premium mills like Xingtai Steel, we manage the chemical and physical characteristics of our metal products from the very start.
By shifting processing in-house—including spheroidizing annealing and wire drawing—we eliminate reliance on third-party processors, shielding our global clients from supply chain disruptions. This vertically integrated framework enables us to maintain low production costs while meeting rigorous international quality standards.
Our facility features Taiwanese precision forming technology and German-engineered multi-station cold heading machinery. With these systems, we manufacture high-capacity runs of 90 Staples and other fasteners that meet a dimensional accuracy tolerance of ±0.02mm and achieve a tensile strength exceeding 1,000 MPa.

By conducting continuous testing under simulated loads, Sinsun ensures that each staple drive achieves clean penetration without bending, buckling, or causing surface blowout, even when applied to high-density composite materials like MDF or tropical hardwoods.
Since our inception in 2006, Sinsun Hardware has transformed from a localized production workshop into a globally recognized supplier of high-precision industrial fasteners.
Sinsun was founded with a clear focus: to build a specialized manufacturing facility dedicated to self-tapping screws and industrial staple wire processing. This singular specialization established our technical core from day one.
Recognizing the growing demand for high-quality fasteners in overseas construction markets, we established our Export Department. This expansion allowed us to supply industrial distributors across the Middle East, South America, and Europe.
To improve quality control, we integrated our raw material processing facility. We installed four high-capacity spheroidizing annealing furnaces alongside in-house wire drawing systems, allowing us to manage wire specifications directly from the hot-rolled wire rod stage.
Sinsun invested in multi-station cold heading machinery from Germany and high-speed header units from Taiwan. This upgrade enabled us to expand our product line, including self-drilling wafer head screws and collated staples.
Our annual manufacturing capacity reached 36,000 tons. This scaling allowed us to ship over 1,100 export containers globally, demonstrating our capacity to support large-scale distributor networks.
To improve shipping turnarounds and support client supply chains, we expanded our storage facility. We established a 12,000 m² warehouse with an 18,000+ pallet capacity, keeping a broad inventory of finished items ready for rapid dispatch.
We integrated four automated continuous heat treatment lines into our facility. This upgrade provides precise control over structural hardness and mechanical performance while ensuring reliable delivery schedules.
Sinsun Hardware supplies structural fasteners tailored to meet the needs of modern industrial operations worldwide.
Our 90 Staples are designed with narrow crowns to sink neatly into wood surfaces, providing secure backing joints in medium-density fiberboards and hardwood cabinets without leaving visible surface marks.
Built for structural durability, our heavy-duty staples secure heavy-duty crates and export pallets. They resist high vibrations and shear forces during maritime transport and multi-port logistics handling.
Our fasteners are engineered to meet building code standards for subflooring, wall sheathing, and roof underlayment. They offer long-term resistance to wood movement and high wind loads.
We understand that packaging plays a vital role in distributor retail displays and warehouse logistics. Sinsun provides comprehensive OEM/ODM packaging services, featuring bespoke box designs, structural cardboard reinforce-ments, and anti-corrosive plastic linings. Our 3D design team creates packaging layouts that optimize container space while protecting your order during transit.
Our shipping team optimizes pallet configurations to make loading and unloading fast and efficient. This focus on logistics helps global distributors reduce container freight costs and improve overall warehouse productivity.
As the construction and manufacturing industries transition toward automation and sustainable materials, fasteners must adapt to new requirements. Sinsun Hardware's R&D division is developing next-generation fastening technologies designed for automated assemblies.
Our technical roadmap focuses on three main developments: improving tensile strengths with high-strength alloy wires, developing biodegradable collation adhesives that leave no chemical residue, and utilizing wear-resistant coating finishes that protect against harsh environments without using hexavalent chromium.
By investing in smart manufacturing systems, we aim to integrate real-time quality tracking into our lines, helping to ensure that our global partners receive consistent, high-performance fasteners.
We build long-term relationships on trust, regulatory compliance, and responsible sourcing. Sinsun Hardware operates in compliance with international standards, including ISO 9001:2015, CE marks for building products, and REACH/RoHS environmental regulations.
Our manufacturing processes incorporate green policies, including water recycling systems in our pickling lines and waste-heat recovery setups on our heat-treatment equipment. Choosing Sinsun as your supply partner helps streamline your supply chain compliance while supporting sustainable manufacturing practices.
