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, 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 specialise 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. We guarantee reliable and rapid lead times for both standard and special orders by using our integrated facility, optimised inventory, and effective planning. Sinsun Hardware is your strategic partner, committed to delivering quality, innovation, and on-time performance worldwide.
The global construction fastener market demands a complex combination of metallurgy control, cost efficiency, and massive production scalability. Sinsun Hardware operates at the center of Northern China's premium steel manufacturing hub. This geographic alignment enables us to source raw materials with exceptional metallurgical properties, specifically optimization of carbon levels and alloying elements (such as C1022A steel) from industry leaders like Xingtai Iron and Steel and Ansteel Group.
By coupling local raw material optimization with advanced high-speed wire drawing, annealing, and automated packaging lines, we minimize material degradation and scrap rates. This enables us to provide cost savings directly to global distributors and OEMs while maintaining a certified production chain that meets global standards (including DIN, ASTM, and JIS).
Over 200 German-imported multi-station cold heading machines producing 1,200+ pieces/min/machine to handle massive volume orders efficiently.
Core steel is sourced directly from Ansteel and Xingtai Group, ensuring consistent microstructures and high-tensile reliability.
An ERP-integrated facility housing over 18,000 pallets allows automated sorting (3,000+ cartons/hour) and rapid cross-dock loading.
Quality control at Sinsun starts at the raw material level. Spheroidizing annealing is performed in-house using computerized atmosphere furnaces to guarantee uniform microstructure, reducing tool wear during forging and eliminating localized stresses in the final fastener.
| Nail Classification | Common Materials | Hardness Range (HRC) | Tensile Strength (MPa) | Available Coatings | Typical Applications |
|---|---|---|---|---|---|
| Coil Nails | Q195, Q235, C1022A | 18 - 25 HRC | 650 - 850 MPa | Bright, EG, HDG, Vinyl | Pallet Assembly, Wood Framing |
| Brad Nails | Q195, Stainless Steel | 15 - 22 HRC | 600 - 800 MPa | Electro-Galvanized | Finishing, Cabinetry, Molding |
| Roofing Nails | Q195, Q235 | 18 - 25 HRC | 700 - 900 MPa | Hot-Dip Galvanized | Asphalt Shingles, Roofing Sheet |
| Concrete / Masonry Nails | #45, #60 High Carbon | 45 - 53 HRC | 1000 - 1200 MPa | Galvanized, Black Phosphated | Concrete Substrates, Brick Walls |
| Masonry Drive Pins | #70 High Carbon, Alloy | 50 - 55 HRC | 1100 - 1300 MPa | Zinc Plated / Dacromet | Powder Actuated Direct Fastening |
The fastener sector is adapting to meet modern regulatory frameworks, high-speed automated installation systems, and challenging climatic environments.
Traditional hexavalent chromium coatings are being replaced by trivalent zinc formulations and advanced organic coatings like Dacromet. These alternatives offer superior salt-spray corrosion protection without hydrogen embrittlement hazards.
Modern framing, roofing, and concrete installations rely heavily on pneumatic tools. High-capacity manufacturing must control collation alignment, angle consistency, and tape adhesion to prevent feeding jams on site.
As structural masonry applications expand, there is a growing demand for fasteners that can penetrate high-strength concrete (exceeding C35/45) without structural deformation or shank breakage.
For wood-frame construction, our ring shank framing nails provide excellent pull-out resistance, resisting structural shifting caused by wood shrinkage and environmental cycles. Heavy-duty galvanization protects the fasteners when used with chemically treated lumber.
Our fluted concrete nails and masonry drive pins are manufactured using high-carbon steel and dedicated heat-treatment lines. This process delivers the high hardness and ductile core required to penetrate masonry without fracturing, ensuring a reliable mechanical connection.
Sinsun produces high-volume coil nails designed for automated pallet production lines. Our production controls ensure consistent collation wire welding and nail spacing, reducing downtime on high-speed industrial assembly lines.
From roofing nails with integrated neoprene washers to marine-grade duplex alloy fasteners, we supply products designed to perform in harsh conditions. Our hot-dip galvanized coatings provide sacrificial cathodic protection to prevent corrosion in coastal and industrial areas.
Challenge: A tier-1 automotive supplier required a custom flange bolt with high vibration resistance and weight reduction for an engine compartment application.
Solution: Sinsun's engineering team optimized the thread profile and introduced a custom alloy steel. We manufactured prototypes, conducted fatigue life testing, and verified thread-locking performance.
Result: Achieved a 15% reduction in weight, passed 2,000 hours of continuous vibration testing, and integrated smoothly into the client's automated assembly system.
Challenge: An offshore engineering contractor required heavy-duty structural fasteners with extreme corrosion resistance for a marine splash zone.
Solution: We supplied high-tensile duplex stainless steel fasteners treated with an advanced passivation process, backed by comprehensive material certificates (EN 10204 3.1).
Result: Zero field failures reported during the initial service life cycle, meeting the project's durability and maintenance-free requirements.
We source carbon steels like Q195 and Q235 for general wood framing, high-carbon steels such as #45 and #60 for masonry nails, and alloy steels like C1022A for self-tapping products, ensuring optimal performance for each application.
We control our heat treatment atmospheres and implement critical baking cycles within 4 hours post-plating. This process diffuses trapped hydrogen, mitigating the risk of delayed brittle fractures under load.
Yes. Utilizing our 12,000 sqm warehouse, we design and produce custom packaging, including cartons, plastic tubs, and master crates, featuring custom artwork and barcoding to simplify retail storage and distribution.
Standard container orders typically ship within 4 to 6 weeks. For custom tooling or specialized coatings, we provide a firm schedule alongside our initial quotation.
Our products are manufactured in compliance with major standards such as DIN, ASTM, and JIS. Upon request, we provide testing reports covering hardness profile, zinc coating thickness, and tensile strength.
We offer flexible order quantities. While our facility is set up for high-volume container runs, we also support smaller MOQs for initial validation programs and specialized engineering projects.
