Direct supply of high-tensile fasteners, anchors, and specialized stamping components from our integrated Northern China manufacturing facilities.
Established in 2006, Sinsun Hardware operates as 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 with an 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).

A comprehensive analysis of design variables, weaving structures, and material performance criteria for critical filtration and sorting applications.
Utilizing high-nickel alloys (such as SS316L, Inconel 600, and Monel 400) to resist acidic, alkaline, and high-temperature environments (up to 800°C) without physical degradation.
Precision calibration of warp and weft counts ensuring uniform pore size distribution, essential for strict pharmaceutical sifting, water purification, and micro-particle analysis.
Spheroidizing annealing and precision cold-drawing of stainless wires preserve high tensile strength (up to 1,000 MPa), preventing weft shifting during high-pressure process cycles.
| Weave Type | Aperture Range (Microns) | Structural Strength Rating | Primary Industrial Use Case |
|---|---|---|---|
| Plain Weave Fine Mesh | 50 – 500 μm | Medium | Chemical separation, plastic extrusion filtration, standard insect barriers |
| Twilled Weave Fine Mesh | 20 – 100 μm | High | Aviation fuel filtration, hydraulic system fluid screen, chemical refining |
| Plain Dutch Weave | 10 – 80 μm | Very High | High-pressure solid-liquid separations, centrifuge filters, water treatment |
| Twilled Dutch Weave | 1 – 15 μm | Extreme | Aerospace instrumentation, ultra-fine pharmaceutical powder classification |
Combining German-engineered manufacturing equipment with precision Taiwanese metallurgy processes to maintain strict quality standards.
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. Utilizing core steel sourced exclusively from Ansteel Group (exceeding 10,000+ tons/year of C1022A steel), we achieve superior microstructure, consistency, and performance in every fastener and structural wire we produce.
Our core mechanical production lines integrate German-engineered multi-station cold heading machines with precision Taiwanese production technology. Our specialized processes, including tail-gripping for drill screws, ensure every fastener is manufactured with utmost accuracy and consistency in our state-of-the-art production facility, sustaining production speeds of up to 1,200+ pieces/min/machine.
SINSUN operates four dedicated in-house heat treatment lines (20-ton/day capacity), allowing for precise and controlled processing time to achieve consistent hardness (HRC 28-32) and enhanced product durability (fatigue life exceeding 50,000 cycles). This in-house capacity ensures both exceptional fastener quality and reliable delivery schedules.
To achieve global reliability, we host a 12,000 sqm dedicated packaging and sorting warehouse with an 18,000+ pallet capacity. Backed by ERP-driven dynamic sorting systems (3,000+ cartons/hour) and rapid direct container loading (50+ TEUs/day), we offer customized packaging, 3D design previews, and full logistics support to deliver a seamless experience from production to shipment.

Exploring how Sinsun custom-engineered fasteners and components addressed complex structural and chemical challenges.
Analyzing key advancements in micro-weaving technology, wire drawing lubricants, and high-accuracy quality assurance.
The global wire mesh market is shifting towards ultra-thin wire profiles. Standard industrial weaving previously focused on wire diameters of 0.1mm to 0.5mm. Modern micro-electronics, fuel cell development, and space engineering now demand high-precision mesh using wire diameters down to 0.02mm (20 microns). Managing wire drawing at this scale requires highly controlled diamond dies, advanced synthetic lubrication to reduce friction-induced heat, and strictly controlled annealing schedules to eliminate inner-crystal stress zones.
To achieve zero-defect tolerances for aerospace fuel separation and medical filtering applications, Chinese factories are shifting away from manual optical checking. Leading operations utilize in-line laser scanner systems that measure warp and weft spacing during the weaving process. This allows for automated loom tension corrections in real time, preventing aperture variations across extensive production runs.
Addressing key engineering, procurement, quality, and logistical queries regarding our industrial product lines.
We maintain a highly adaptable approach to volume requirements. While our cold-heading and wire drawing departments are optimized for high-capacity wholesale runs, we run dedicated prototype lanes to handle lower MOQs for engineering approval cycles and new product introduction phases.
Yes. Custom engineering from technical drawings is one of our primary capabilities. Our engineering division works with CAD/DXF/STEP files to manufacture custom threads, head shapes, wire diameters, and custom weaving parameters, matching ISO, DIN, ANSI, and JIS frameworks.
We deploy systematic Statistical Process Control (SPC) across all manufacturing bays. This incorporates raw material coil testing, dimensional gauging during head forging, core hardness checks after heat treatment, and final optical inspection. We provide complete Mill Test Certificates (MTC) and salt spray reports on demand.
Production cycles vary based on part geometry, alloy composition, and surface treatment requirements. Standard fasteners are generally dispatched within 4 to 6 weeks. Firm delivery timelines are clearly outlined with every official engineering quotation.
Yes. Providing pre-production physical samples for client testing and verification is standard practice. We verify that samples match mechanical drawing specs before shipping to the client's laboratory for final approvals.
