Engineered structural components optimized for urban renewals, transportation corridors, and public space renovations throughout Madrid, Barcelona, and Andalusian municipalities.
Under Spain's comprehensive Recovery, Transformation, and Resilience Plan (*Plan de Recuperación, Transformación y Resiliencia*), the Spanish public sector is driving massive capital expenditures into the digitization, decarbonization, and modernization of public spaces and transport nodes. The integration of structural aluminum alloys in municipal facilities has transitioned from an aesthetic option to a structural mandate. Across metropolitan areas like Madrid, Barcelona, Valencia, and Bilbao, urban planners are replacing traditional galvanized steel with high-performance aluminum extrusions.
This systemic migration is fueled by several factors unique to the Iberian peninsula: Spain's extensive coastal boundary demands materials capable of withstanding aggressive saline humidity without structural degradation. In cities like Malaga and Alicante, marine-grade aluminum profiles prevent oxidation, reducing long-term public maintenance liabilities.
Furthermore, the Spanish rail network (ADIF) and local metropolitan operators (TMB, Metro de Madrid) are aggressively pursuing lightweighting technologies. By reducing the tare weight of rolling stock and transit platform equipment, municipal networks achieve substantial energy savings, directly contributing to the European Green Deal.
The technological trajectory of municipal infrastructure focuses on smart-city integration. Extruded aluminum serves as both the structural skeletal framework and the physical conduit for digital technologies. As municipal lighting poles, public transit shelters, and directional signages are retrofitted with IoT sensors, 5G small cells, and ambient light controls, thermal management becomes critical.
Our current technical roadmap prioritizes co-engineered extrusions combining thermal dissipation channels with high structural yield points. Utilizing 6000-series alloys (predominantly 6063-T5 and 6082-T6), we manufacture custom hollow shapes that provide integrated routes for wiring and optical cables. This protects delicate components from physical vandalism and environmental extremes.
Over the next five years, the Spanish market will demand higher levels of secondary (recycled) aluminum integration. In alignment with Spain’s Circular Economy Strategy (España Circular 2030), our engineering team is optimizing alloy formulations to incorporate post-industrial scrap while maintaining the mechanical properties required by EN 755-2 and EN 12020 structural parameters.
Qingdao Kangjian Aluminum Industry Technology Co., Ltd. — A certified global partner for high-precision extrusions.
Qingdao Kangjian Aluminum Industry Technology Co., Ltd. is situated in the Jimo District of Qingdao, having established a state-of-the-art production base spanning 200 mu (approximately 133,000 square meters), featuring 80,000 square meters of manufacturing space and 4,000 square meters of administration facilities.
With an annual production capacity of 15,000 tons of high-end aluminum profiles, our manufacturing facility houses five advanced extrusion lines (ranging from 700T, 1150T, 1450T, up to a heavy-duty 2500T press). This allows us to handle complex extrusion profiles for municipal systems, rail transit components, and automotive engineering applications.
We hold international certifications that demonstrate our commitment to quality, safety, and reliability. This includes ISO 9001, ISO 14001, IATF 16949 (Automotive Quality System), ISO 22163 / IRIS (Railway Industry Management Standard), EN 15085 (Welding of Railway Vehicles), DIN 6701 (Adhesive Bonding of Railway Vehicles), and AWS/DIN welding qualifications.
Founded with a vision to deliver premium, heavy-industry aluminum profiles that challenge global benchmarks, Kangjian Aluminum has established a dual-sea footprint. Relying on the deep-water port infrastructure of Qingdao, we export high-strength, structural profiles directly to European logistical nodes.
Whether it is structural components supporting heavy gantry cranes in Nordic ports or customized municipal lighting assemblies installed in Spain's historical avenues, our engineering ensures durability. "Made in China" under Kangjian is synonymous with international engineering compliance, material integrity, and delivery stability.

How Kangjian Aluminum aligns with global engineering supply chains.
We continuously develop cutting-edge aluminum extrusion solutions, offering a wide range of high-precision profile products that meet the demands of demanding applications, to help our customers achieve their design ambitions.
Quality is the cornerstone of Kangjian. We adhere to international standards, implement precise control throughout the entire process, and ensure that every meter of profile exceeds expectations, delivering stable and reliable outstanding quality.
We are well-versed in the ways of global trade and are committed to providing flexible, efficient and transparent foreign trade services. Customer-oriented, respond quickly to demands, optimize logistics, and become a solid and reliable backing for you to expand into the international market.
Operating in the Spanish municipal sector requires strict adherence to European Harmonized Standards (EN). Our engineering procedures conform to European regulations, ensuring seamless adoption into municipal bids and public works.
By working with local customs brokers and European logistics firms, we coordinate the delivery of DDP/CIF shipments straight to municipal sites or warehouses in Madrid, Barcelona, Valencia, and Bilbao.
Global infrastructure projects are highly vulnerable to supply chain volatility. Our digital smart factory in Qingdao minimizes manufacturing cycle times while ensuring quality control. By leveraging computerized monitoring across our 5 extrusion presses (including our 2500T line), we track extrusion speed, pressure, and cooling parameters in real-time. This ensures consistency across every production run.
Our in-house CNC machining workshops allow us to perform drilling, milling, tapping, bending, and assembly under one roof. Providing finished components directly to Spanish assembly lines reduces intermediate logistical handling, tariffs, and storage fees.
Strategically located near the Port of Qingdao, we offer direct maritime shipping routes to major Spanish container hubs (Algeciras, Valencia, Barcelona, Bilbao). This geographic advantage, combined with our large-scale raw material inventory, helps protect Spanish municipal buyers from domestic European market fluctuations and local material shortages.

Important details for Spanish procurement managers, project designers, and compliance officers.
For coastal municipalities such as Barcelona, Valencia, and Malaga, we recommend 6063-T6 or 6082-T6 alloys. These structural grades offer excellent mechanical properties and resistance to marine corrosion. For harsh salt-spray environments, we recommend a Class 20/25 anodized finish or a maritime-grade Qualicoat powder coating to prevent pitting corrosion.
Yes, we hold the EN 15085-2 (Class CL1) certification, which is the highest level of welding certification for railway vehicles and structural trackside components. Additionally, we maintain ISO 22163 (IRIS) and DIN 6701 certifications, ensuring full engineering compliance for components destined for European transit authorities like ADIF.
Tooling and sample design generally takes 10 to 15 days. Once samples are approved, mass extrusion and precision machining require 20 to 25 days. Direct maritime shipping from Qingdao to Spanish ports (such as Valencia, Barcelona, or Algeciras) averages 30 to 35 transit days. For urgent structural prototypes, we can arrange air freight via Madrid-Barajas (MAD) Airport.
