Designed to withstand maritime climates, high mechanical stresses, and stringent European environmental standards. Explore our high-demand structural product selection.
The Netherlands occupies a highly critical hub within the European economic landscape, driven by high-tech manufacturing in Eindhoven (Brainport), massive logistics hubs in Rotterdam, sophisticated agricultural greenhouse construction (Westland), and offshore wind infrastructure across the North Sea. These specialized sectors place strict mechanical demands on screw manufacturing.
For industrial structures operating in coastal areas, fasteners must offer superior resistance against high atmospheric salinity (C4 and C5-M corrosion classifications). Dutch building contractors and engineers are bound by the strict directives of the European Construction Products Regulation (CPR - EU No 305/2011) and the harmonized standard EN 14592. Fasteners imported or specified for construction projects require verifiable CE marking, traceability, and high mechanical performance.
Our capabilities align with this demand. Through optimized materials processing, Sinsun Hardware supplies Dutch distributors, developers, and engineering firms with fasteners characterized by high tensile performance (>1,000 MPa), superior fatigue strength, and advanced coatings designed to prevent hydrogen embrittlement and galvanic corrosion.
The largest self tapping screw production base in northern China
Sinsun Hardware, established in 2006, is a leading manufacturer and global supplier of high-quality fasteners. Operating from a 30,000 sqm integrated facility, we run modern production zones, a 12,000 sqm smart warehouse (18,000+ pallet capacity), and support centers servicing key markets worldwide.
Our manufacturing workflow features vertical control, starting from raw wire processing down to final surface finishing. By leveraging advanced Taiwanese drawing machines and gas-fired spheroidizing annealing furnaces, we obtain raw steel wires with precise grain microstructures, ensuring mechanical stability in the subsequent cold heading stages.
Equipped with German multi-station cold heading systems, Sinsun maintains dimensional tolerances within ±0.02mm, a critical parameter for automatic screw-driving systems used in modern industrial prefabrication. To support the technical requirements of European contractors, Sinsun executes 12+ strict quality control checks, verifying case depth, core hardness (HRC 28-32), and tensile values across every single production lot.
Operating inside the EU single market requires understanding local regulatory environments. Below is our engineering outline detailing how Sinsun Hardware satisfies the strict demands of Dutch civil and industrial sectors.
Compliant with harmonized timber construction rules. Essential parameters such as characteristic yield moment, withdrawal capacity, and head pull-through capacity are monitored in our quality laboratories.
To survive saline North Sea breezes, Sinsun offers custom coatings including mechanical galvanizing, Dacromet, and organic Ruspert treatments proven to withstand 1,000+ hours in salt spray testing (ISO 9227) without red rust.
High-speed automated assembly lines require screws with tight tolerances. Our German-engineered heading machinery controls crucial dimensions to within ±0.02mm, ensuring consistent feed rates.
Sinsun Hardware supplies specialized industrial projects across the European continent. Our fasteners find extensive application in:
From our starting point in 2006, Sinsun has grown into a leading fastener manufacturer. Explore our history of expansion, advanced technological integration, and logistics capacity build-up.
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 global markets.
Sinsun expanded its control over quality by adding four spheroidizing furnaces for raw material processing and in-house wire drawing capabilities. This ensures superior consistency starting from the wire rod stage.
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.
Sinsun's growth in 2021 was defined by reaching 36,000 tons in annual production and fulfilling international orders with over 1,100 export containers, underscoring our capacity to deliver at scale.
To ensure timely delivery for our clients, we operate a 1,200-square-meter ready-stock warehouse. This facility is dedicated to supporting efficient daily distribution and meeting routine supply needs.
The addition of four heat treatment lines in 2025 significantly boosts our production capacity. This translates to greater consistency in product quality and stronger guarantees for on-schedule delivery.
Our quality standard relies on verifiable testing procedures. We start with premium raw materials from XING TAI Steel, then perform in-house spheroidizing annealing and precision wire drawing in our own plant. By maintaining absolute oversight of the raw materials, Sinsun ensures uniform carbon levels, preventing cracking during cold heading.
At our testing laboratory, every shipment is accompanied by detailed test sheets outlining performance tests, including:
| Inspection Parameter | Target Standards | Methodology |
|---|---|---|
| Tensile Strength | 1,000+ MPa | Universal Hydraulic Testing Machine |
| Surface Hardness | HRC 28-32 | Rockwell & Vickers Microhardness Testers |
| Corrosion Performance | 1,000+ hrs without red rust | Neutral Salt Spray Chambers (ISO 9227) |
| Dimensional Control | Tolerances ≤ ±0.02mm | Automated CCD Optical Sorting Inspection |
| Surface Finish | Ra ≤ 0.4μm | Surface Profilometers |
Our 12,000 m² logistics and warehousing facility features an organized modern inventory tracking system, optimizing the sorting of over 20,000 unique SKUs. By managing stock configurations dynamically, we secure raw components ahead of demand peaks, insulating clients against supply disruptions.
For our partners in the Netherlands and wider Europe, Sinsun offers custom export arrangements (FOB, CIF, DDP terms). We coordinate with shipping providers to facilitate customs clearances, delivering ready-to-use fasteners directly to construction sites, distribution facilities, or maritime warehousing nodes across Rotterdam, Amsterdam, and Eindhoven.
No compromise, no supply disruptions. Just reliable fastening systems designed to last.
As mechanical demands evolve, Sinsun Hardware prioritizes research into manufacturing methods that lower environmental footprints while increasing product durability.
With the European Union implementing the Carbon Border Adjustment Mechanism (CBAM), importing components into the Netherlands requires clear carbon transparency. Sinsun is implementing strategies to source steel wires processed with gas-fired annealing systems and transitioning toward sourcing green steel rods. We work closely with our material suppliers to reduce trace emissions per ton of manufactured fasteners.
Sinsun complies fully with EU RoHS and REACH regulations, eliminating hexavalent chromium (CrVI) across all surface treatments. Our modern passivation methodologies employ trivalent chromium (CrIII) and zinc-flake coats, satisfying environmental requirements without lowering rust-resistance ratings.
