Deploying state-of-the-art cold heading technology to deliver zero-defect fasteners designed specifically for structural timber, concrete work, and infrastructure systems in the Berlin-Brandenburg metropolitan region.
Berlin is undergoing one of the most rapid structural evolutions in Europe. The shift towards sustainable urban environments, coupled with the expansion of the Berlin-Brandenburg metropolitan industrial corridor (including automotive gigafactories, clean technology hubs, and high-tech parks), has accelerated the demand for precision fastening solutions. As developers execute projects like the Siemensstadt Square redevelopment and large-scale public transportation updates, there is zero tolerance for fastening failures.
Modern German construction requires compliance with strict building directives. For wood engineering, structural steel assembly, and heavy masonry, the reliability of lag screws, self-drilling fasteners, and high-strength concrete nails is critical. Engineers and purchasing directors in Berlin require products that not only exhibit extreme shear strength and pull-out resistance but also integrate seamlessly with modern German assembly machinery. By providing certified quality that matches local DIN standards, our direct factory-to-market model bypasses layers of markup, guaranteeing pricing stability and quality assurance for large-scale operations.
When sourcing industrial fasteners for Germany, compliance is not optional—it is the foundation of structural safety. For building permits in Berlin, construction materials must conform to European Technical Assessments (ETA) and harmonized EN standards. Sinsun Hardware designs and manufactures fasteners that satisfy these rigid expectations from raw material formulation to final surface finishing.
Meeting the DIN EN ISO 9227 standard, our zinc-plated and hot-dip galvanized fasteners endure 1,000+ hours in salt spray testing chambers without showing signs of red rust. For coastal or heavy-weather applications, we supply Marine-Grade A4 316 Stainless Steel.
Designed to comply with DIN 7981 and DIN 571 regulations, our structural screws feature optimized pitch and thread angles for effortless driving, maximum grip, and exceptionally high resistance to pull-out forces.
Sourced from high-grade raw steel (Xingtai Steel), our products undergo rigorous verification processes to ensure consistent mechanical behavior. We offer material certifications and heat batch records for full structural compliance.
Operating Northern China's largest self-tapping screw production base, we combine legacy craftsmanship with continuous industrial scaling.
Sinsun was founded with a clear directive: to build a state-of-the-art facility optimized for self-tapping screws. This early specialization forms the core of our manufacturing quality today.
We established our Export Department, taking our specialized self-tapping screws to international markets and matching European building supply networks.
Added 4 advanced spheroidizing annealing furnaces and in-house wire drawing lines. We gained absolute quality control, beginning directly with the raw material.
Installed German multi-station cold heading machinery and expanded our production line to include high-performance drill tail self-drilling screws.
Reached an annual production output of 36,000 tons, shipping more than 1,100 containers globally, showing our capability to handle major bulk supplies.
Opened a dedicated 1,200 sqm ready-stock facility, providing rapid distribution capability and stable inventory options for our partners.
Integrated 4 new heat treatment lines, guaranteeing perfect, uniform hardness profiles and ensuring reliable delivery timelines for large-scale operations.
At Sinsun Hardware, our production strength is driven by German-imported machinery, precision Taiwanese technology, and a dedicated team of engineers. We offer more than 20,000 SKUs of nails, screws, wires, and rivets. Every production batch undergoes 12+ stringent quality checks to guarantee high-performance characteristics: surface finish of Ra ≤ 0.4μm, 1,000+ hours salt spray test resistance, dimensional tolerances within ±0.02mm, tensile strength of 1,000+ MPa, and consistent hardness profiles (HRC 28-32).
Our quality control starts right from the selection of premium raw steel coils from XING TAI Steel. We process these materials in our own plant via spheroidizing annealing and wire drawing, using gas-fired furnaces to create a uniform steel microstructure. In-house processing ensures our finished fasteners perform reliably without brittle fractures, making them ideal for heavy structural wood and concrete applications across Germany.
To support global supply chains, Sinsun Hardware operates a 12,000 sqm smart warehouse holding over 18,000 pallets. We offer customized packaging designs, quick prototyping, 3D render designs, and full logistics support to ensure a seamless experience from factory production to delivery at your construction site or distribution hub.
As the construction industry focuses on sustainable development and building efficiency, Sinsun Hardware is actively investing in new technology to meet tomorrow's requirements. Our developmental roadmap focuses on three main pillars:
We are phasing out traditional electroplating to focus on trivalent chromium zinc coatings and water-based mechanical plating. These coatings reduce environmental impact while matching the durability requirements of the EU REACH and RoHS directives.
By integrating ERP and IoT inventory management in our 12,000 sqm warehouse, we provide real-time updates to European distributors, maintaining stable material flows and minimizing lead times.
We are engineering lightweight carbon alloy steels designed for self-drilling applications. These alloys increase drilling speeds through steel substrates while keeping head breakage rates near zero.
