Engineered to withstand seismic demands and corrosive Mediterranean coastal environments.
The Largest Self-Tapping Screw & Fastener Base in Northern China
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, Russia, and the expanding industrial sectors of Greece.
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).
Analyzing key structural projects, marine requirements, and standard shifts across Greece.
Greece’s strategic location makes it a primary logistical hub for Southern Europe. Megaprojects such as the expansion of the Port of Piraeus, the massive redevelopment at The Hellenikon Metropolitan Park, and the modernization of national highway networks (such as Egnatia Odos) demand highly durable structural fastening elements. In marine applications, saltwater corrosion is an ongoing issue. Sinsun's Hot-Dip Galvanized (HDG) eye bolts, J-bolts, and custom structural framing screws are designed specifically to withstand harsh marine environments, offering superior anti-corrosion properties exceeding 1,000 hours in salt spray testing.
As Greece accelerates its green energy transition with massive solar photovoltaic installations in the Peloponnese, Thessaly, and Crete, the demand for specialized solar tracker framing fasteners has surged. Sinsun provides customized T-bolts, hex bolts, and carriage bolts that secure mounting structures against heavy wind loads and seismic shifts. Since Greece lies in a seismically active zone, structural fasteners must align with strict Eurocode 8 structural standards. Sinsun's high-tensile fasteners (up to 1,000+ MPa strength) ensure the structural integrity of these solar farms, preventing mechanical failures over their 25-year operational lifespans.
Importers and distributors in Athens, Thessaloniki, and Patras face complex challenges when sourcing industrial components. The European Union's regulatory environment, including CBAM (Carbon Border Adjustment Mechanism), CE mark compliance, and stringent anti-dumping policies, requires supply chain transparency. Many European distributors struggle with fluctuating local lead times and limited capacity from regional factories. Sinsun Hardware solves this dilemma by operating a massive 12,000 sqm smart warehouse, which holds over 18,000 pallets in ready stock. This localized stock model, paired with efficient ocean freight logistics routing directly to Piraeus port, ensures Greek buyers maintain reliable inventory levels without carrying excessive capital overhead.
Utilizing premium raw materials, advanced cold-heading machinery, and automated heat treatment.
At Sinsun, quality control begins at the source. We utilize premium raw materials from XING TAI Steel, followed by 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 a uniform steel microstructure, consistency, and structural performance in every fastener we produce.
Our facility combines German-engineered multi-station cold heading machines with precision Taiwanese production technology. Specialized processes, including tail-gripping for drill screws, ensure every fastener is manufactured with utmost accuracy. SINSUN operates four dedicated heat treatment lines, allowing for precise and controlled processing time to achieve consistent hardness (HRC 28-32) and enhanced product durability. This in-house capacity ensures both exceptional fastener quality and reliable, on-time delivery schedules for our global partners.
Discover our journey of expansion, technological integration, and global market penetration since 2006.
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, directing our 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 and industrial bolts 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 basic assembly, securing precise control from the raw material stage to ensure superior consistency.
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, strengthening 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 high volumes to global markets.
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 translates to greater consistency in product quality and stronger guarantees for on-schedule delivery, meeting your project needs with confidence.
How Sinsun fasteners are deployed across major Greek structural and marine networks.
Heavy-duty Eye Bolts and J-Bolts secure marine structures, ship fittings, dock crane components, and coastal loading assemblies. Sinsun's multi-layered surface treatment options ensure these critical components resist salt spray corrosion and constant humidity.
High-strength carriage bolts, T-bolts, and framing fasteners align structural steel channels. Sinsun's precision dimensional tolerances (±0.02mm) allow automated assembly machinery to install solar brackets swiftly, reducing labor costs on site.
Residential developments in Athens utilize Sinsun's wholesale plasterboard and self-tapping screws. The sharp needle points and deep thread engagements ensure clean penetrations through light-gauge metal framing without pre-drilling.
