Explore our highly-demanded industrial screws and concrete nails. Engine-tested, corrosion-resistant, and structural-grade solutions direct from the manufacturer.
Established in 2006, Sinsun Hardware is a leading manufacturer and global supplier of high-quality fasteners. Working from a massive 30,000 m² integrated facility, we operate modern production zones, a 12,000 m² smart warehouse with 18,000+ pallet capacity, and multi-language support channels. Over 8,500 containers are exported annually to key global markets in the Middle East, Southeast Asia, South America, and Russia.
Fastening is not just about connecting components; it is about guaranteeing long-term structural integrity. We design and manufacture fasteners tailored for specialized global environments.
From heavy-duty blue concrete screws to high-strength black concrete nails, our building fasteners anchor structures globally. Specifically treated for high shear resistance, our concrete fasteners guarantee reliable, lifetime anchoring in solid block, brick, and high-pour concrete columns.
Coastal installations demand superior metallurgy. Sinsun's rust-resistant 316 and 304 marine-grade stainless steel lag screws are purpose-built to withstand saltwater corrosion, high humidity, and aggressive chemical cleaners, keeping docks, boat decks, and shoreline structures structurally sound.
Modern assembly lines require fasteners with absolute dimensional consistency. Our self-tapping and self-drilling screws utilize German-grade tooling to assure a perfect fit at high assembly speeds, preventing drive-slip, head-shearing, and overall equipment downtime.
The global fastener market is shifting toward higher demand for microstructural integrity and chemical surface longevity. No longer are simple zinc-plated screws acceptable for structural engineering; global standards require certified salt-spray performance, defined Rockwell hardness ranges, and trace metal verification.
Sinsun Hardware meets this global demand by implementing strict vertical integration. We procure raw alloy coils directly from Xingtai Steel, running them through our in-house spheroidizing annealing furnaces and drawing processes. This completely eliminates internal material defects before the wire ever reaches our headers. This high level of quality control guarantees that importers receive uniform bulk shipments that comply perfectly with standard and project requirements.
Securing cross-border shipments demands compliance with strict regional guidelines. We specialize in localized quality validation.
Our fasteners are designed, fabricated, and tensile-tested to meet strict ASTM (American Society for Testing and Materials) and DIN (Deutsches Institut für Normung) specifications. This assures effortless engineering clearance for municipal bidding projects and commercial construction contracts.
We provide verified documentation for salt spray testing (exceeding 1000+ hours for our high-end marine finishes). Our coatings include mechanical galvanization, high-durability zinc plating, and specialized chemical passivation processes designed to withstand highly acidic environments.
Supporting custom packaging designs, bulk barcode tagging, and custom wood/plastic crate options. Our localized logistics support ensures smooth customs clearance at major international ports by providing full export licensing and material safety data reports (MSDS).
Since our founding in 2006, Sinsun Hardware has transformed from a localized production workshop into a key contributor to the global fastener supply chain. Our progression highlights our dedication to technological expansion and raw material control.
Sinsun was established with a clear goal: constructing a state-of-the-art production factory focused entirely on self-tapping screws, building fundamental expertise.
Established the Sinsun Export Department, introducing our specialized fasteners to construction markets across Europe, Russia, and South America.
Added 4 advanced spheroidizing furnaces for raw material processing, allowing in-house wire drawing and complete structural control of steel inputs.
Acquired high-precision German multi-station cold heading machines and Taiwanese tail-gripping systems to launch our premium self-drilling screw lines.
Achieved a record annual output of 36,000 tons, exporting over 1,100 high-capacity containers to global construction and hardware importers.
Inaugurated a dedicated 12,000 m² warehouse facility, keeping a massive stock of components ready for immediate delivery.
Operationalized 4 new high-capacity heat treatment lines, securing perfect core hardness (HRC 28-32) and ensuring reliable delivery times.
Our facility runs with a focus on manufacturing precision. Sinsun's fasteners undergo 12+ strict testing procedures during production to ensure consistent physical tolerances.
Sourced directly from Xingtai Steel. We handle custom annealing and spheroidizing in-house to secure a clean microstructure free of surface stress defects.
German-imported headers maintain a dimensional accuracy of ±0.02mm, which prevents installation slips during automatic assembly operations.
Our four new heat treatment lines carefully manage temperature cycles to secure high tensile strength (1,000+ MPa) and long-lasting hardness.
Expert answers to critical metallurgical, structural, and procurement inquiries from engineers and purchasing managers.
Premium options for wood construction, subfloor installations, roofing projects, and heavy-duty structural anchoring.
