Engineered for construction, heavy masonry, timber framing, and industrial structural fastening. Manufactured to EN 14592, ASTM F1667, and DIN standards.
In modern industrial construction, civil infrastructure, and heavy automated assembly, structural fasteners such as steel nails, concrete pins, and pneumatic coil collated nails are no longer mere commodities. They represent critical structural anchors where micro-fractures, improper yield strength, or deficient anti-corrosion treatments can trigger systemic structural failures and catastrophic Total Cost of Ownership (TCO) escalations.
"As Northern China's premier fastener production base, Sinsun Hardware integrates raw wire spheroidizing annealing, high-speed multi-station cold heading, controlled-atmosphere gas-fired heat treatment, and automated logistics to redefine global fastener reliability."
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 and industrial construction nails, 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).
We specialize in offering unique fastening solutions that are tailored to your specific needs. Our technical team works directly with clients from design to manufacturing, providing support for unusual materials, coatings, dimensions, and performance requirements to ensure that each custom order matches exact specifications.
From Sinsun's founding in 2006, Sinsun has grown into a leading Chinese fastener manufacturer. Explore our journey of expansion, from establishing exports in 2012 and integrating German technology in 2018, to achieving a 36,000-ton annual output and adding advanced heat treatment lines by 2025.
Sinsun began with a singular focus in 2006: to build a factory dedicated to self-tapping screws and precision industrial fasteners. This foundational specialization established our core expertise from the ground up, remaining the unwavering commitment behind every piece of fastener we manufacture today.
The year 2012 marked a pivotal step for Sinsun with the establishment of our dedicated Export Department. From that point forward, our specialized self-tapping screws and high-tensile nails began reaching industrial clients across South America, Europe, the Middle East, and Southeast Asia.
In 2015, Sinsun expanded its control over quality by adding four spheroidizing furnaces for raw material processing and in-house wire drawing capabilities. This strategic upgrade moved our production beyond screw and nail cold heading, beginning with precise metallurgical control right from the raw material stage.
Our production capability was enhanced in 2018 with new German multi-station cold heading machines. Concurrently, we grew our product line to include a variety of drill tail screws and high-hardness fluted concrete drive pins. This dual development strengthened our specialized manufacturing foundation.
Sinsun's growth in 2021 was defined by two key metrics: reaching 36,000 tons in annual production and fulfilling international orders with over 1,100 export containers, underscoring our operational capability to deliver at massive global scale.
To ensure timely delivery for urgent client orders, we operate a 1,200-square-meter ready-stock warehouse as of 2023. This facility is dedicated to supporting efficient daily distribution and meeting routine customer supply demands without delay.
The addition of four continuous heat treatment lines in 2025 significantly boosts our high-hardness steel processing capacity. This directly translates to greater consistency in product structural strength and stronger guarantees for on-schedule delivery.
At SINSUN, our quality control begins at the source. We start with premium raw wire rods sourced directly 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, decarbonization-free wire, and consistent performance in every fastener we produce.
At SINSUN, we combine German-engineered multi-station cold heading machines with precision Taiwanese production tooling and automated inspection lines. Our specialized processes—including precision shank threading, tail-gripping for drill screws, and point forming for masonry nails—ensure every fastener is manufactured with dimensional tolerance of ±0.02mm.
SINSUN operates four dedicated continuous mesh-belt heat treatment lines, allowing for precise temperature control and atmosphere management to achieve consistent surface hardness (HRC 50-56 for concrete nails, HRC 28-32 for structural nails) without hydrogen embrittlement risk. This in-house capacity ensures both exceptional fastener quality and reliable delivery schedules.
As global supply chains demand greater agility, transparency, and lead time predictability, Sinsun Hardware has transformed into a benchmark Industry 4.0 smart factory. By coupling IoT-enabled manufacturing lines with cloud-managed inventory systems, we deliver unprecedented supply chain resilience.
Every cold heading machine and heat treatment furnace is connected to a centralized ERP system monitoring feed rates, die wear, and thermal variance in real time, preventing batch deviations.
With 18,000+ automated pallet capacity and barcode-managed rack storage, orders are picked, packed, and staged for container loading with 99.9% inventory accuracy.
High-speed optical visual sorters inspect 100% of finished nails and drive pins, detecting head eccentricity, point burrs, or thread malformations at up to 1,500 units per minute.

Fluted concrete nails feature helical or vertical flutes machined into high-carbon steel (typically 55# or 60# steel hardened to HRC 50-56). The longitudinal flutes channel displacement friction and cut precise keyways into concrete matrix, providing up to 40% higher withdrawal resistance compared to smooth nails while preventing concrete surface spalling or nail buckling under high-impact installation.
We utilize advanced surface plating technologies, including heavy Hot-Dip Galvanizing (HDG according to ASTM A153), Mechanical Zinc Plating, and organic Zinc-Flake coatings (Geomet/Magni style). Combined with micro-passivation sealants, our fasteners prevent red rust formation even after 1,000+ hours of salt spray testing (ASTM B117 / ISO 9227 standard), making them ideal for coastal or industrial chemical environments.
Yes. Sinsun's wire-collated and paper-collated coil nails are manufactured strictly to international dimensional standards (15° wire coil angle, 28° or 34° paper strip angle). They feature uniform wire welding and zero head variance, ensuring smooth, jam-free feeding across all major pneumatic and cordless nailer brands.
For standard production items, our minimum order quantity (MOQ) starts at 1 to 3 metric tons per SKU. For custom OEM dimensions, specialized coatings, or custom printed box packaging, our standard production lead time is 20-25 days post-sample approval, supported by our 12,000 m² warehouse facilities for rapid staging.
Spheroidizing annealing heats high-carbon raw wire rod to a precise temperature range (~740°C) in gas-fired protective atmosphere furnaces, converting lamellar cementite into uniform spherical carbides. This increases wire ductility and malleability, ensuring that during ultra-high-speed cold heading, the steel forms complex nail heads and sharp points without internal stress cracks or micro-fractures.
