Company Profile & Vision

Qingdao Kangjian Aluminum Industry Technology Co., Ltd. is located in Jimo District, Qingdao City. Our enterprise mainly produces and processes aluminum alloy industrial profiles, rail transit profiles, aerospace, automotive and Marine profiles. We have successively obtained the National Industrial Product Production License, GB/T19001-2016/ISO9001, ISO14001, and IATF16949 Automotive Industry Quality Management System Certification.

Our production base spans 200 mu with 80,000 square meters of factory space. Equipped with extruders ranging from 700T to 2500T, we are the largest aluminum profile manufacturer in the Qingdao area, focusing on energy-saving building materials and high-speed rail components.

Brand Story: Coastal Innovation

Forging the world's aluminum light on the coast of the Yellow Sea. In 2022, several founders recognized the lack of domestic high-end aluminum extrusion capabilities. They founded Kangjian to fill this void, leveraging Qingdao's port advantages to create a "dual-sea layout" serving both domestic and international high-end markets.

From Nordic port cranes to the world's top infrastructure projects, the logo of "KANGJIAN ALUMINIUM" stands for "Made in China" industrial backbone.

Strategic Advantages: Why Partner with a Chinese Factory?

Supply Chain Integration

China's aluminum cluster provides immediate access to raw ingots, specialized surface treatment chemicals, and rapid tooling (die) manufacturers, reducing the prototype-to-mass-production cycle by 40%.

Compliance & Compliance

We provide full documentation for RoHS, REACH, and ASTM standards. Our in-house lab conducts tensile tests, salt spray tests (for marine grade), and spectral analysis to ensure 100% material purity.

Localized Technical Support

For our global clients in the US and Europe, we offer DFM (Design for Manufacturing) consulting. We help optimize your CAD drawings to reduce material waste and extrusion difficulty.

Future Trends & Application Scenarios

Aluminum is the "Green Metal" of the future. Our customized profiles are at the heart of several emerging sectors.

New Energy Vehicles (NEV)

Lightweighting is key. We produce battery tray frames and motor housings that extend EV range while maintaining structural integrity during impacts.

Industrial Automation

T-Slot and V-Slot profiles for robotics and CNC frames. Our 6061-T6 profiles provide the rigidity needed for high-precision mechanical arms.

Sustainable Architecture

Thermal break aluminum window profiles that significantly reduce building energy consumption, meeting modern LEED certification requirements.

Expert Q&A: Aluminum Extrusion Procurement

What is the typical lead time for custom aluminum extrusion dies?

For standard profiles, die creation takes 7-10 days. Complex industrial profiles with tight tolerances (±0.1mm) may take 15 days. Sample production follows immediately after die testing.

How does Kangjian ensure the quality of 6061 vs 6063 alloys?

We use OES (Optical Emission Spectroscopy) to verify the chemical composition of each batch of aluminum logs. 6061 is prioritized for structural components, while 6063 is used where surface finish and anodizing quality are paramount.

Can you provide CNC machining and surface finishing in-house?

Yes. Our "One-Stop" service includes 5-axis CNC milling, drilling, tapping, and advanced surface treatments like hard anodizing, powder coating, and electrophoresis.

What are your MOQ requirements for wholesale orders?

Typical MOQs start at 500kg per profile. However, for strategic long-term partners, we offer flexible trial runs to support R&D and prototype phases.
