In the landscape of modern material science, 3000 series aluminum—primarily alloyed with manganese—stands as a cornerstone for industrial applications requiring excellent workability and moderate strength. As a premier manufacturer based in Qingdao, our facility specializes in the production of 3000 series profiles, leveraging state-of-the-art extrusion technology to meet the rigorous demands of global markets.
3003, 3004, and 3105 aluminum alloys are known for their exceptional resistance to corrosion, high plasticity, and weldability. Unlike heat-treatable alloys, the 3000 series is non-heat treatable, making it ideal for processes such as deep drawing, spinning, and roll forming. This makes it the preferred material for HVAC systems, heat exchangers, food packaging, and architectural components where durability and formability are non-negotiable.
Located in the Jimo District, Qingdao, our production base covers 80,000 square meters. With an annual output of 15,000 tons and advanced extrusion lines (including 2500T, 1450T, 1150T, and 700T units), we possess the capacity to fulfill large-scale global procurement orders while maintaining stringent quality control standards (ISO9001/ISO14001). Our integration of welding systems (EN15085, ISO3834) ensures that every profile leaving our facility meets international structural integrity requirements.
The global aluminum industry is undergoing a paradigm shift towards circularity and precision engineering. As an industry-leading supplier, Qingdao Kangjian aligns with these trends by prioritizing sustainable manufacturing processes, including energy-efficient extrusion cycles and waste reduction management. We see an increasing demand from international markets—specifically Europe, Japan, and North America—for alloys that not only provide structural reliability but also support lightweight vehicle and building designs.
Our "dual-sea layout"—leveraging Qingdao's logistics hub and our global export network—enables us to act as a bridge for international enterprises looking to mitigate supply chain risks. We are not just a supplier; we are a partner in innovation, helping companies reduce their carbon footprint through the application of high-performance aluminum profiles.
Q1: What are the main advantages of 3000 series aluminum compared to 6000 series?
3000 series (Al-Mn) offers better ductility and formability, making it superior for bending and shaping applications. 6000 series (Al-Mg-Si) is stronger due to heat treatment but less malleable. We help you choose based on your specific application requirements.
Q2: Can your factory handle custom OEM/ODM orders?
Yes, we have 5 dedicated extrusion lines and in-house CNC machining capabilities to support end-to-end custom profile development.
Q3: How do you ensure quality for international shipping?
We adhere to IATF16949 and ISO standards. Every batch undergoes chemical composition testing and physical properties inspection before loading.
Q4: What is your typical lead time for international wholesale?
Our strategic location in Qingdao port allows us to streamline logistics. For standard profiles, we offer rapid turnaround, and for custom orders, we work closely with your engineering team to ensure timely delivery.
Qingdao Kangjian Aluminum Industry Technology Co., Ltd. is committed to becoming the trusted innovator in aluminum extruded profiles. Established in 2022, we have rapidly expanded our capabilities, serving markets from Japan to Europe. Our core philosophy—"Quality builds trust, Innovation drives success"—guides every aspect of our operation, from alloy selection to the final surface treatment. Partner with us to leverage the strength of Chinese manufacturing for your global business needs.
