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).
A timeline of innovation, investment, and strategic expansion supporting global engineering industries since 2006.
Sinsun began with a singular focus: to build a factory dedicated to self-tapping screws, establishing our core expertise from the ground up.
Establishment of our Export Department. Specialized self-tapping screws and structural fasteners began reaching markets worldwide.
Added 4 spheroidizing furnaces for raw material processing and in-house wire drawing, ensuring total metallurgical control.
Production enhanced with German multi-station cold heading machines and advanced drill tail screw manufacturing lines.
Reached 36,000 tons in annual production, fulfilling international orders with over 1,100 export containers annually.
Optimized ready-stock capacities to service rapid-delivery regional agreements and reduce lead times for key trade hubs.
Integrated state-of-the-art continuous heat treatment furnaces to guarantee precise mechanical properties and structural hardening.
Every single nut, bolt, and screw conforms to precise engineering tolerances, validated through rigorous laboratory testing.
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.
To prevent hydrogen embrittlement—a critical issue in structural nuts under high-tension applications—our heat treatment lines operate with strictly controlled carbon potential and atmosphere zones. This ensures that fasteners deployed in Algiers infrastructure withstand dynamic loading and long-term strain without structural decay.

Poorly threaded nuts lead to galling and structural failure under load. Sinsun's precision cold heading and rolling techniques ensure unified thread profiles, allowing fast installation and maximum strip-out resistance during pneumatic tightening on site.
Algiers' proximity to the Mediterranean Sea introduces significant airborne chloride levels. Our specialized hot-dip galvanized and zinc-nickel plating solutions prevent galvanic corrosion, ensuring maintenance cycles are extended by up to 15 years.
Every production batch undergoes spectral analysis to verify chemical composition, alongside hardness mapping and dimensional checks before shipping to Algeria.
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.
Understanding the import regulations and delays that can occur at the Port of Algiers (Port d’Alger), we maintain a streamlined logistics system. Our smart shipping coordination ensures that weight limits per container, sea freight packaging (heavy-duty wooden crates, moisture-barrier plastic wraps), and palletized layouts are optimized. This prevents cargo damage during transit and expedites custom inspections, helping local Algerian distributors maintain healthy inventory levels without disruption.
From heavy machinery construction to telecommunication framework installations, Sinsun provides a complete spectrum of threaded fasteners.
Every month, we welcome international buyers and engineering auditors to inspect our modern manufacturing and heat-treatment workflows.
Transparency is the cornerstone of SINSUN's growth. We regularly participate in global industrial and hardware trade shows across major cities, providing direct technical consulting to engineers, procurement officers, and project developers.
Answers to crucial technical and logistical questions asked by procurement professionals importing to Algiers.
Generally, ocean shipping from Tianjin Port (Northern China) to the Port of Algiers takes between 30 and 45 days, depending on shipping line routing. Our advanced 12,000 m² smart warehouse facilitates quick sorting, packing, and container loading, reducing manufacturing lead time to 20-30 days for bulk customized production.
For coastal applications, we recommend fasteners coated with Hot-Dip Galvanizing (HDG), Geomet, or Zinc-Nickel alloy. In salt-spray chambers conforming to ASTM B117 standards, these coatings endure upwards of 1,000 hours before red rust appears, ensuring structural longevity in high-salinity zones.
Yes. All our heavy-duty fasteners conform to equivalent EN, DIN, and ISO specifications (such as DIN 934 for hex nuts and ISO 898-2 for mechanical properties). We provide Mill Test Certifications (MTC) conforming to EN 10204 3.1 with every batch shipment.
Importing into Algeria requires strict documentary compliance. We issue all necessary documents, including the Commercial Invoice, Packing List, Clean Report of Findings (Certificate of Conformity issued by SGS/Bureau Veritas), EUR.1 Certificate (if applicable), and Bill of Lading, all meticulously checked for compliance with the Algerian Ministry of Trade regulations.
Absolutely. We specialize in custom configurations. Our engineering department can design and manufacture fasteners according to your CAD drawings, and we can provide 3D design previews before fabricating molds, ensuring perfect alignment with custom machinery dimensions.
For standard SKUs in stock, the MOQ is flexible, but to ensure economic feasibility for international freight and customs clearance at Algiers Port, we typically advise starting with a combined minimum container load (20-foot FCL, approx. 20-25 tons of product). Mixing different fastener products within a single container is fully supported.
