Sinsun Hardware, established in 2006, is a leading manufacturer and global supplier of high-quality fasteners. As Northern China's largest producer of Self-Tapping Screws, we operate from a gigantic 30,000 sqm integrated facility that includes modern production zones, a 12,000 sqm smart warehouse (18,000+ pallet capacity), and multi-language customer support centres. Our yearly supply of over 8,500 containers consistently services key global markets such as the Middle East, Southeast Asia, South America, and Russia.
Our production prowess is driven by German-imported machinery, precision Taiwanese technology, and a dependable staff of trained specialists. We offer over 20,000 SKUs of nails, screws, wires, and rivets, each undergoing 12+ stringent quality checks to assure outstanding polish (Ra ≤ 0.4μm), corrosion resistance (1,000+ hours salt spray), dimensional accuracy (±0.02mm), high strength (1,000+ MPa), and consistent hardness (HRC 28-32).
The 1013J flat wire staple features a standard 10mm crown and a precise 13mm leg length. Manufactured from premium low carbon or high tensile steel, it is engineered for heavy-duty applications where thin materials must be held without tearing or slicing through the substrate.
Available in premium galvanized iron wire, copperized finishes, and SUS304/SUS316 stainless steel variants. Sinsun's OEM 1013J line is coated with advanced polymer adhesives to minimize friction during high-speed pneumatic driving, preventing staple jams and ensuring smooth penetration.
Specifically engineered to function seamlessly with industrial-grade 10J pneumatic air staplers (such as 1013J, 1022J series guns). The strict dimensional accuracy of ±0.02mm guarantees minimal mechanical wear on the driver blade and firing valve mechanisms.
Widely utilized by European and North American OEM furniture manufacturers for securing structural fabrics, leather linings, and webbing bands to softwood and medium-density fiberboards (MDF). The 13mm leg length provides deep anchorage without risking back-side blowout.
Applied in securing interior door panels, acoustic insulation sheets, and trunk linings. The high fatigue resistance of Sinsun-engineered wire ensures that vibrations from vehicle operation do not loosen the mechanical connection over time.
Crucial for commercial building envelopes where synthetic wraps and underlayments must be tightly secured to wood studs. Sinsun's electro-galvanized coating provides superior rust resistance, meeting ASTM standards for outdoor structural exposures.
Initiated operation with a core focus on establishing specialized self-tapping screw and industrial fastener production lines in Northern China, building our technical foundation.
Established our dedicated Global Export Department, opening trade channels across the Middle East, South America, and Europe, setting global quality benchmarks.
Integrated four gas-fired spheroidizing annealing furnaces and in-house cold wire drawing lines. Sourced raw materials from XING TAI Steel to manage quality from the initial raw wire stage.
Acquired and deployed multi-station cold heading machinery from Germany alongside Taiwanese tooling systems. Diversified product capabilities with premium self-drilling screw lines.
Reached an annual production output of 36,000 tons, successfully packing and shipping over 1,100 export containers to global partners and logistics hubs.
Operationalized a 12,000 sqm modern smart warehouse facility, securing storage for over 18,000 pallets to minimize shipping delays and support immediate supply demands.
Commissioned 4 new state-of-the-art continuous atmosphere heat treatment lines, ensuring unmatched dimensional stability and structural durability for heavy-duty fasteners.
At SINSUN, our quality control begins at the source. We start with premium raw materials from XING TAI Steel, then perform in-house spheroidizing annealing and precision wire drawing in our own plant. This end-to-end control, supported by our advanced drawing machines and gas-fired furnaces, ensures superior microstructure, consistency, and performance in every fastener we produce.
SINSUN offers flexible OEM and ODM packaging tailored to your needs. With a professional packaging team and a 12,000 m² warehouse, we provide custom packaging, 3D design previews, and full logistics support to deliver a seamless, worry-free experience from production to shipment.
Whether you require bulk industrial packaging, branded boxes with custom barcodes, or weather-resistant plastic tubs, Sinsun ensures that your products arrive in pristine condition, regardless of distance or transit conditions.
Integrating real-time vision sensor inspection on our high-speed header machines to detect micro-deformations down to the micron level, ensuring zero-defect staple coils.
Developing next-generation organic trivalent chromium coatings and zinc-flake systems that reduce chemical impact while maintaining superior rust resistance.
Engineering lightweight, high-hardness alloyed steel wires designed to ease tool penetration through hardened composites and high-density engineered woods.
