View SpecificationsFounded in 2006, Sinsun Hardware has developed into a premier force in the global manufacturing and distribution of premium industrial fasteners. Operating from our vast 30,000 square meter integrated facility, we oversee every step of production. Our facility includes modern manufacturing areas, a 12,000 square meter smart warehouse with space for over 18,000 pallets, and multi-lingual service centers to support clients worldwide.
We ship more than 8,500 containers annually to major markets in Europe, the Middle East, Southeast Asia, South America, and regions with strict quality requirements. By combining advanced manufacturing processes with our streamlined logistics network, we ensure reliable delivery of high-quality industrial components to Ireland and the EU.
From the harsh marine environment of the Atlantic seaboard to modern pharmaceutical hubs in Cork and data centers in Dublin, Ireland's industries require fasteners that meet high standards of performance and reliability.
Ireland’s coastal and offshore wind farms require structural nuts with high resistance to vibration and marine-grade, salt-spray-tested coatings.
Our structural fasteners meet CE / UKCA mark requirements under EN 1090-1 to comply with Irish building regulations.
Our large-scale production helps Irish distributors secure consistent pricing and stable inventory, minimizing the risks of supply disruptions.
Industrial applications in Ireland face challenging environmental conditions, particularly high humidity and marine salt spray. Sinsun Hardware addresses these challenges with specialized corrosion-resistant solutions:
We maintain high levels of product consistency by sourcing our raw materials directly from premium suppliers like XING TAI Steel. In-house processing, including spheroidizing annealing and precision wire drawing, helps us control material properties from the initial stages of production.
Our production floor features German-engineered multi-station cold heading machinery and precision Taiwanese thread-rolling systems. This combination of advanced equipment allows us to maintain tight tolerances and high dimensional accuracy for all our fasteners.
To support this output, we added four automated heat treatment lines in 2025. These lines allow us to achieve uniform hardening and tempering, ensuring every batch meets international strength specifications.
From a dedicated factory founded in 2006 to a leading international supplier of industrial fasteners, explore the milestones that define our growth.
Sinsun began with a singular focus: to build a specialized manufacturing plant for self-tapping screws and core fastening components.
We established our dedicated export division, expanding our market reach to industrial sectors across Europe, the Middle East, and beyond.
We added four spheroidizing furnaces and wire-drawing facilities, allowing us to control raw material quality right from the wire stage.
We upgraded our production line with German multi-station cold-forming machines to produce high-precision custom fasteners.
Annual production output reached 36,000 tons, shipping more than 1,100 containers globally to support large-scale infrastructure projects.
We established our large-scale automated warehousing space to maintain high stock levels and ensure reliable delivery schedules.
We integrated four computer-controlled heat treatment lines, expanding our control over quenching and tempering processes.
Navigating international supply chains requires reliable logistics. We provide direct shipping routes and complete document support to ensure efficient delivery to Irish ports.
We work with experienced logistics partners to handle shipping requirements into major Irish ports, including Dublin Port, the Port of Cork, and Shannon Foynes.
Our export team handles documentation to support smooth customs clearance: EORI validation, commodity code classifications (Chapter 7318), and certificates of origin are provided with every shipment.

Aligning with Ireland's Climate Action Plan, we are integrating eco-friendly processes and digitalization into our manufacturing practices.
In compliance with the EU's REACH and RoHS directives, we are shifting our coating lines away from hexavalent chromium (CrVI). Our newer zinc flake and trivalent passivation (CrIII) lines offer comparable corrosion protection without using restricted chemicals, helping Irish clients meet environmental requirements.
To support modern manufacturing and construction, we are implementing batch-level QR coding. This allows clients to scan a box label to access material certifications, chemical compositions, and test results, improving material traceability on the job site.
By transitioning our four heat treatment lines to natural gas and incorporating heat recovery systems, we have improved energy efficiency. We are also planning to install rooftop solar panels on our 30,000 sqm facility to offset electricity consumption during peak production hours.
Find answers to common questions about technical specifications, ordering processes, and shipping to the Irish market.
We supply structural bolts and nuts with CE marking and Mill Test Certifications (MTC) conforming to EN 10204 3.1. Our manufacturing lines follow ISO 9001:2015 quality controls, ensuring chemical compositions and mechanical strengths match European structural requirements.
Production typically takes 25 to 35 days depending on the size and customization of the order. Ocean shipping from China to Dublin Port or the Port of Cork generally takes 35 to 40 days, meaning total delivery times range from 60 to 75 days.
Yes. For high-corrosion coastal environments in Ireland, we offer Hot-Dip Galvanizing (HDG) to ISO 1461, as well as multi-layer Zinc Flake coatings (like Geomet) that can withstand over 1,000 hours of salt spray testing without showing red rust.
For high-tensile components, we use acid-free cleaning processes and mechanical or zinc flake coating methods. This avoids the acid-pickling steps that can introduce hydrogen into the steel, reducing the risk of sudden structural failures under load.
For standard metric and imperial nut styles, the MOQ is typically 1 to 2 tons per size. For custom OEM sizes or specific materials, the MOQ is evaluated by our engineering team based on tooling and raw material availability.
Yes. Our packaging department can print custom cartons, plastic tubs, and bulk bags featuring your brand, part numbers, and local EAN/UPC barcodes to support retail or warehouse management systems.
We source our steel coils from established domestic mills, primarily Xingtai Iron & Steel. This includes carbon steel grades like C1008, C1022, 35K, and 45K, as well as stainless steel grades SUS304 and SUS316, ensuring consistent material characteristics.
Our export documentation team provides accurate HS Codes (primarily under heading 7318), detailed commercial invoices, packing lists, and bill of lading documents. This helps your customs broker process the import declaration and manage VAT/duty calculations efficiently.
