Heavy-duty, precision-engineered products conforming to EN standards and adapted for high-stress French environmental conditions.
The industrial and commercial sector for high-performance fasteners in France is undergoing a profound transformation. Driven by stringent environmental regulations, structural safety revisions under the Eurocodes framework, and a national push for modernization in residential and civil construction, procurement managers demand fasteners that exhibit unparalleled longevity and strict dimensional tolerances.
French projects require compliance with Eurocode 3 (Steel structures) and Eurocode 5 (Timber structures). All high-load lag screws and self-drilling fasteners must maintain reliable tensile strength without risk of hydrogen embrittlement.
With massive Atlantic and Mediterranean coastlines, France is highly susceptible to atmospheric corrosion. Fasteners utilized in these regions require marine-grade 316 stainless steel or advanced zinc-plated coatings with over 1000 hours of salt spray testing resistance.
The "Réglementation Environnementale 2020" pushes the French building sector to choose materials with low carbon footprints, leading to a massive increase in wood-frame structures which demand high-end wood screws, lag screws, and customized deck fasteners.
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 France, the wider EU, the Middle East, Southeast Asia, South America, and North America.
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.
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.
Sinsun expanded its control over quality by adding four spheroidizing furnaces for raw material processing and in-house wire drawing capabilities, ensuring 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.
Reaching 36,000 tons in annual production and fulfilling international orders with over 1,100 export containers, proving our capacity to deliver massive orders globally.
To ensure rapid delivery, we operate a 12,000 square meter smart warehouse facility dedicated to supporting daily distribution and client safety stocks.
The addition of four new heat treatment lines in 2025 significantly boosts our production capacity and ensures microstructural hardness consistency for structural wood screws.
Sinsun Hardware combines state-of-the-art machinery with meticulous quality assurance protocols to deliver the ultimate structural integrity in fastening technology.
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.
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.
By bypassing external preprocessing agents, we eliminate micro-voids, material variance, and decarbonized surfaces. This is critical for high-load fasteners like self-tapping structural wood screws and concrete masonry anchors. Our downstream heat treatment process is continuously monitored to confirm uniform temper and martensite formation.
Understanding the exact environment in which our fasteners function allows us to customize metallurgy and surface chemistry.
From Brest to Marseille, exposure to highly corrosive marine aerosol requires marine-grade fasteners. Sinsun's SS316 deck and lag screws provide unmatched protection against chloride pitting and structural fatigue in coastal board walks and tourist docks.
In the French Alps, heavy timber chalets and structural frameworks depend on heavy-duty wood screws. Our heat-treated lag screws offer the shear-load capacity needed to resist cyclic thermal contraction and heavy snow loads, conforming strictly to Eurocode 5 standards.
French manufacturing and assembly plants rely on our high-hardness self-tapping screws for automated conveyor lines. Consistent dimensional accuracy ensures seamless feed rates in industrial sorting robots, reducing line stoppage to near-zero.
European distributors and French industrial buyers frequently face the challenge of balancing premium quality with cost efficiency. The modern fastener industry is capital-intensive and demands massive raw material inventory and rapid logistical response times. Sinsun's manufacturing ecosystem provides critical economic and mechanical advantages:
By holding raw material contracts directly with major mills, drawing our own wire rods, and running four independent heat treatment systems in-house, we eliminate intermediate supply chain layers. This guarantees cost predictability even during global steel price volatility.
We employ automated optical sorting machines that inspect each individual fastener for thread pitch, drive geometry, and overall length. This automated QA allows us to meet the PPM (Parts Per Million) defect standards expected by French tier-1 automotive suppliers.
Our heat-treatment lines utilize monitored gas-carburizing atmospheres to prevent decarburization. Carbon depth is maintained between 0.05mm and 0.18mm depending on the thread profile, producing a hard, wear-resistant outer shell while retaining a tough, ductile core to resist sudden shear stress.
With a 12,000 sqm facility containing over 18,000 pallet positions, we store buffer stock for long-term contract partners. When a French client places a call-off order, we can prepare, pack, and export the shipping container within days, minimizing lead times.
Explore our main export lines, manufactured to exceed the standards of French structural engineering and BTP distributors.
As sustainability, automated warehousing, and raw material efficiency dominate corporate purchasing strategies, industrial fasteners are evolving beyond simple steel hardware into highly engineered components.
Hexavalent chromium (CrVI) is prohibited in European markets under REACH and RoHS regulations. Sinsun has systematically transitioned to trivalent zinc plating and advanced thin-film organic coatings. These methods offer superior corrosion performance without violating environmental health directives.
Major construction engineering projects in Paris, Lyon, and Marseille increasingly demand a complete paper trail for structural fasteners. Sinsun offers full material traceability reports (En 10204 Type 3.1 certification) detailing the chemical ladle analysis and mechanical testing profiles of raw materials.
