2. Qingdao Kangjian Aluminum: Quality and Technical Competence

Founded in 2022 in the industrial hub of the Jimo District, Qingdao, China, Kangjian Aluminum has established a reputation for manufacturing excellence in high-performance aluminum extrusions. Our state-of-the-art facility covers over 200 mu, with 80,000 square meters of production area and an office facility of 4,000 square meters.

With an annual capacity of 15,000 tons of high-grade profiles and a staff of experienced metallurgists and engineering technicians, we serve crucial industrial sectors, including rail transit, aerospace, automotive, shipbuilding, and commercial architecture. Our primary operation relies on 5 specialized extrusion lines designed to manage various profile dimensions and alloy configurations: one 2500T extruder, one 1450T extruder, one 1150T extruder, and two 700T extruders.

By leveraging our strategic location near Qingdao Port, we offer seamless global logistics, supplying critical aluminum profiles to demanding markets across North America, Europe, East Asia, and beyond.

5. Advanced Custom Solutions & Technical Capabilities

From initial design evaluation to final precision machining, Kangjian Aluminum supports customers throughout the custom product lifecycle. Industrial applications often require custom post-extrusion processes to meet exact engineering specifications:

• Precision CNC Machining: Our machining division performs high-speed milling, multi-axis drilling, tapping, punching, and deburring to deliver ready-to-assemble components.
• Extensive Surface Finishes: We offer comprehensive surface options, including architectural-grade anodizing (clear, bronze, black), electro-deposition coating, weather-resistant powder coatings, and sandblasting.
• Co-Engineering Support: Our engineers review customer CAD/SolidWorks drawings to optimize geometries for material flow, wall-thickness uniformity, and overall manufacturing cost efficiency.

By integrating extrusion and finish processing under one management system, we reduce lead times, minimize product handling damage, and simplify procurement processes for our international clients.

6. International Standards, Compliance & Engineering Trust

Entering international supply chains requires strict compliance with geographic industrial codes. Kangjian Aluminum ensures its extruded profiles meet international testing protocols:

• North America (ASTM / AA Standards): Extrusions are calibrated to ASTM B221 specifications for alloy compositions and mechanical performance benchmarks.
• Europe (EN Standards): Material processing and tolerances align with EN 755 (extruded rods, tubes, profiles) and EN 12020 (precision profiles in alloys 6060 & 6063).
• Welding and Bonding Audits: For railway rolling stock structures and automotive subframes, our EN15085 welding and DIN6701 structural bonding certifications guarantee joint integrity.

We provide full documentation packages, including material test reports (MTR), dimension inspection sheets, and coating thickness certificates, for every export shipment.

7. Brand Values: Engineering Clean Extrusions

At Kangjian Aluminum, our operational values focus on combining industrial capacity with sustainable manufacturing processes. As global markets transition toward a circular economy, we adapt by optimizing our resource usage and production techniques:

• Resource Management: We integrate remelting processes to reclaim clean, in-house extrusion scrap, helping to lower the carbon footprint of our products.
• Environmental Standards: In compliance with ISO14001 certification, we monitor and treat all surface treatment wastewater and process air emissions, meeting local and national environmental guidelines.
• Energy Conservation: Our plant has upgraded to variable-frequency air compressor drives and energy-efficient heating controls on our billet pre-heat ovens to reduce electrical and gas consumption.

By prioritizing process control and quality, we supply reliable structural components to support the clean energy, mass transit, and sustainable architecture projects of tomorrow.
