Achieving structural supremacy through rigorous raw material vetting and state-of-the-art tooling processes.
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).
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.
For our ODM Wire Welded Mesh, we utilize structural-grade steel coils that undergo physical verification before entering the welding lines. This is critical for industrial applications where structural integrity cannot be compromised. The in-house drawing lines enable custom wire gauge modifications to suit particular projects, offering unique elasticity or rigidity features based on the application scenario.
At SINSUN, we combine 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.
Applying this level of machinery oversight to our ODM Wire Welded Mesh lines, our computerized mesh welding lines ensure absolute control over grid parameters, heat inputs, and shear strength at each joint. Every cross-wire weld is monitored for dimensional tolerance and thermal consolidation, delivering uniform mesh sheets and rolls that resist buckling under heavy loads.

From Sinsun 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. This foundational specialization established our core expertise from the ground up. It remains the unwavering commitment behind every screw we manufacture today.
The year 2012 marked a pivotal step for Sinsun with the establishment of our Export Department. From that point forward, our specialized self-tapping screws began reaching customers across the world, expanding our mission beyond borders.
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 manufacturing, beginning with precise control from the raw material stage. It ensures superior consistency and performance in every piece screw we produce.
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. 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. This period underscored our capacity to deliver at scale to a global market.
To ensure timely delivery for our clients, we operate a 1,200-square-meter ready-stock warehouse as of 2023. This facility is dedicated to supporting efficient daily distribution and meeting your routine supply needs.
The addition of four heat treatment lines in 2025 significantly boosts our production capacity. This directly translates to greater consistency in product quality and stronger guarantees for on-schedule delivery, meeting your project needs with confidence.
SINSUN operates four dedicated heat treatment lines, allowing for precise and controlled processing time to achieve consistent hardness and enhanced product durability. This in-house capacity ensures both exceptional fastener quality and reliable delivery schedules. See our advanced heat treatment systems in action, supporting our end-to-end manufacturing control.
Thermal tempering and hardening are critical phases, especially when manufacturing reinforcing items like wire welded mesh, anchoring bolts, and high-strength concrete screws. Because we handle our heat treatment processes inside Sinsun's self-contained site, we are able to manage the carbon potential and furnace atmosphere continuously, preventing localized decarbonization or surface defects that commonly cause component failure under real-world stress loads.
Navigating the complex needs of multinational supply chains with reliable structural-grade mesh configurations.
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.
From highway stabilization grids to mining shaft support structures, our welded wire mesh products serve as primary load redistribution matrices. We optimize our structural designs for rapid site deployment, significantly lowering overall onsite setup times and installation costs.
Industrial procurement relies on strict conformity. Our facilities operate under strict EN and ASTM benchmarks, providing chemical analysis reports and mechanical load testing credentials for every batch, facilitating easy customs clearance across North American, European, and Middle Eastern entry ports.
Forging a sustainable path for metal production through green technologies and smart factory automation.
As the construction and manufacturing fields shift toward intelligent automation and eco-friendly practices, Sinsun Hardware is proactively adapting our technological map. Our 2026-2030 modernization roadmap features the integration of robotic welding arm systems on our mesh lines, guaranteeing perfect dimensional accuracy across thousands of square meters of welded grid.
In addition, Sinsun is lowering its carbon footprint by converting our heat treatment lines to lower-emission clean gas configurations, while investing in solar setups on our vast 30,000 sqm roof structure. By utilizing green electricity, we help our global B2B clients meet strict ESG goals without raising unit procurement prices.
Every month, we welcome clients from across the country for on-site factory visits, demonstrating our transparency and production strength. As a trusted industry partner, we actively participate in global exhibitions to connect, exchange insights, and showcase innovation — building lasting relationships based on quality and reliability.
Transparency is key to building authentic business partnerships. By opening our doors to third-party inspectors (such as SGS, TUV, and BV), we provide our partners with verified data. Our testing laboratory has dedicated machines to perform tensile, shear, salt spray, and microstructural analysis right on our premises, giving you the security of complete quality control before any cargo leaves our gates.
