In the contemporary landscape of global manufacturing, extrusion aluminium profiles have transitioned from basic structural components to high-precision engineering assets. This shift is driven by the urgent demand for lightweighting in electric vehicles (EVs), the structural integrity required for renewable energy infrastructures, and the sophisticated aesthetics of modern architecture.
Our analysis leverages decades of combined expertise in metallurgy and precision extrusion. Qingdao Kangjian Aluminum Industry Technology Co., Ltd. (est. 2022) embodies this authority, operating an 80,000 sqm facility with ISO 9001, ISO 14001, and IATF 16949 certifications, ensuring every profile meets the rigorous safety and quality benchmarks demanded by rail transit and aerospace sectors.

We are pushing the boundaries of the 6xxx and 7xxx series alloys. By optimizing the T5/T6 heat treatment processes, we achieve superior mechanical properties—balancing tensile strength with elongation. Our R&D focus includes low-carbon recycled aluminum to meet the "Green Supply Chain" requirements of the 2030 net-zero targets.
The roadmap involves integrating real-time laser monitoring during the extrusion process to maintain tolerances as tight as +/- 0.05mm. Coupled with our in-house CNC precision machining, we provide ready-to-assemble components for drones, robot arms, and medical devices.
Beyond traditional anodizing and powder coating, we are exploring Fluorocarbon (PVDF) coating and eco-friendly chrome-free passivation to enhance corrosion resistance in marine and oil drilling environments, extending product lifecycles by up to 300%.
Lightweighting is the core of modern rail logistics. We supply large-section profiles that satisfy EN 15085 welding standards and ISO 22163 management systems, ensuring safety and energy efficiency for subways and high-speed trains globally.
Providing high-strength 7075 and 2024 equivalent profiles for structural frames and drone arm components. Our quality control follows the stringent AWS and DIN standards essential for aerospace reliability.
Photovoltaic frames and solar mounting systems require high weatherability. Our profiles are designed for rapid installation and extreme wind-load resistance, supporting the global transition to sustainable power.
Precision-engineered profiles for medical imaging beds and laboratory automation systems, where non-magnetic properties and hygienic surface finishes are non-negotiable.
Located in the Jimo District of Qingdao, Qingdao Kangjian Aluminum Industry represents the pinnacle of "Made in China 2025" for the aluminum sector. Our factory 4.0 strategy focuses on:
Qingdao Kangjian Aluminum Industry Technology Co., Ltd. is the largest aluminium profile manufacturer in the Qingdao area. We specialize in aluminium profiles for high-speed railways, subways, auto parts, ships, and energy-saving buildings.
Successively obtained the National Industrial Product Production License, and a suite of certifications including: GB/T19001-2016/ISO9001, GB/T24001-2016/ISO14001, IATF16949, ISO22163, EN15085, ISO3834, AWS, and DIN6701.
Our infrastructure covers 200 mu (approx. 133,000 sqm) with an annual output of 15,000 tons. We operate 5 extrusion production lines (1450T, 700T x2, 2500T, 1150T) managed by a team of 90 dedicated professionals. Our reach extends to South Korea, Japan, USA, and Europe, serving global top-tier projects.
We provide documentation compliance for ASTM (USA), EN (Europe), and JIS (Japan) standards. This ensures that a profile manufactured in Qingdao fits seamlessly into a project in Hamburg or Houston without technical friction.
Our facility adheres to the highest environmental (ISO 14001) and labor standards. We offer full traceability for raw materials, supporting your corporate ESG (Environmental, Social, and Governance) reporting requirements.
Our experienced foreign trade team assists in optimizing customs classification and choosing the most cost-effective shipping routes through Qingdao's logistics hub, reducing total landed costs for our partners.
Procurement directors for Fortune 500 companies prioritize four pillars: Quality Reliability, Lead Time Stability, Technical Scalability, and Cost Efficiency.
We act as a technical extension of your design team. Whether it’s a complex hollow profile or a multi-port heat sink, our engineers provide DFM (Design for Manufacturability) feedback to reduce costs and improve performance.
Utilizing our 5-line production matrix, we can pivot capacity to meet urgent orders, maintaining a 30% faster delivery cycle than industry averages in the region.
From die-making to final inspection, we provide transparent project tracking. Quality builds trust, and trust builds long-term win-win partnerships.
