Learn More →Spain's construction sector operates under stringent structural standards defined by the **Código Técnico de la Edificación (CTE)**, alongside European structural guidelines (Eurocode 2 & Eurocode 8). As Spain accelerates its green transition and smart city infrastructure development—ranging from utility-scale solar farms in Andalusia and Aragon to high-speed rail expansions and marine civil engineering along the Cantabrian and Mediterranean coasts—the demand for high-performance, certified anchoring systems has escalated dramatically.
For engineering firms and industrial distributors in Seville, Barcelona, Bilbao, and Madrid, securing a reliable anchoring system is not merely about mechanical fastening; it is about risk mitigation. Wind tracking solar arrays require anchors capable of resisting high fatigue, while seaside marine environments demand advanced corrosion resistance matching Class C4 or C5-M ratings. At Sinsun Hardware, we design, test, and supply technical fastening solutions tailored exactly to these demanding European environmental exposures.
Established in 2006, Sinsun Hardware is a leading manufacturer and global supplier of high-quality industrial fasteners. As one of Northern China's largest producers of structural fasteners and self-tapping screws, we operate from a massive 30,000 sqm integrated production facility. Our infrastructure features modern manufacturing zones, a 12,000 sqm smart warehouse (18,000+ pallet capacity), and multi-language technical customer support channels.
By delivering over 8,500 containers annually across European, Middle Eastern, and South American markets, Sinsun ensures project timelines are met with uncompromising quality. Our manufacturing processes utilize German-imported multi-station cold heading systems and precision Taiwanese production tooling to guarantee dimensional consistency and long-term durability under stress.
To maintain rigorous structural integrity, we trace our engineering processes from raw metallurgical chemistry to complex heat-treatment cycles.
We start with premium steel coil sourced from industry leaders like Xingtai Steel. Our in-house spheroidizing annealing and wire-drawing facilities refine the microstructure of carbon steels, enabling uniform grain structure and superior forging properties.
Using German multi-station cold headers and Taiwanese thread-rolling equipment, we shape raw wire into precise sleeve, wedge, and drop-in designs with dimensional accuracy maintained within ±0.02mm and surface roughness Ra ≤ 0.4μm.
Four advanced mesh belt conveyor heat treatment lines manage tempering, hardening, and carburizing. This guarantees consistent core hardness values of HRC 28-32 and high tensile strength ratings exceeding 1,000 MPa.
Construction in modern Europe demands structural calculations that account for environmental degradation and seismic actions. Seismic zones in Spain (such as parts of Granada, Malaga, and Murcia) require anchors certified under ETAG 001 (or EAD 330250 and EAD 330499) for cracked concrete conditions. Sinsun continues to expand its development roadmap to meet these requirements:
From our beginnings as a regional manufacturer to a global scale supplier of critical structural fixing components.
Founded Sinsun Hardware with a focus on core cold-forged fasteners. Established early raw material quality controls with Northern China steel mills.
Expanded trading infrastructure to support international markets in Southeast Asia and South America. Initiated strict compliance with international ASTM, DIN, and ISO specifications.
Integrated German-designed multi-station cold heading machinery and introduced digital scheduling within the manufacturing facility.
Achieved an annual output of 36,000 tons. Completed the construction of our 12,000 sqm automated warehouse with over 18,000 pallet spaces, and added advanced heat treatment lines to increase production of high-tensile structural anchors.
Proven anchoring performance in real-world infrastructure and energy applications throughout Spain.
Challenge: An engineering firm in Seville required anchors with high dynamic load capacity and wind-uplift resistance to secure solar tracker frames in varying soil-concrete foundations.
Solution: Sinsun supplied OEM Heavy-Duty mechanical anchors made with precision C1022A carbon steel core, featuring custom-tempered expansions designed to absorb lateral vibrations.
Result: Successful anchor validation with zero torque failures during installation, completing the project's structural requirements ahead of timeline expectations.
Challenge: Fixings installed in coastal environments near Valencia suffered premature degradation due to high humidity and salt chloride exposure.
Solution: Sinsun manufactured custom sleeve and chemical stud anchors using duplex-grade stainless steel with specialized passivation coatings, certified to handle C5-M high-corrosion classifications.
Result: Continuous structural stability with no corrosion signs during routine municipal inspections, extending the maintenance lifespan by over 150%.

We actively participate in global hardware, construction, and green energy exhibitions to keep tabs on global safety compliance. These touchpoints allow us to gather valuable industry insights and continuously upgrade our processes to better serve European industrial procurement demands.
Providing reliable technical support, supply chain security, and custom OEM manufacturing.
We work closely with structural design teams to optimize anchor dimensions, recommend steel grades, and conduct proof-load calculations to ensure safety at a competitive cost.
Operating under ISO 9001 quality management guidelines, our labs document raw materials, cold-forging metrics, and heat-treatment cycles, performing salt spray and HRC hardness testing on every batch.
By leveraging an ERP-driven warehouse management system with 18,000+ pallet spaces, we maintain standard stock levels to facilitate rapid dispatch and achieve over 99% on-time delivery.
We offer comprehensive OEM/ODM manufacturing capability, supporting custom sizing, specialized coatings (zinc flake, Dacromet), and customized product packaging designs.
Our logistical infrastructure accommodates shipping demands worldwide, ensuring a stable fastener supply chain for commercial distributors and contractors alike.
Equipped with German-imported multi-station cold heading systems and Taiwanese thread formers, we achieve consistent high-volume production with low dimensional tolerances.
