In modern structural engineering and high-volume manufacturing, the selection of the correct structural substrate and surface finishing is paramount to performance, longevity, and structural safety. China has emerged as the global epicenter for high-precision anodized aluminium profile manufacturing, coupling sophisticated metallurgical control with scale-driven efficiency. By transitioning raw bauxite and ingots through vertical processes—extrusion, aging, CNC milling, and electrochemical anodization—leading suppliers deliver tailored mechanical properties for severe-environment applications.
Utilizing high-grade architectural and structural alloys (Al-Mg-Si series) including 6063-T5, 6061-T6, and custom structural configurations for ultimate tensile strength.
Electrochemical anodization process produces a uniform aluminum oxide layer (Al₂O₃), integrated directly with the substrate, improving hardness and corrosion resistance.
Engineered to international aerospace and automotive specifications, certified under IATF 16949, EN 15085, and DIN 6701 criteria for structural integrity.
Officially registered and established in 2022, Qingdao Kangjian Aluminum Industry Technology Co., Ltd. is located in Jimo District, Qingdao City. The enterprise mainly produces and processes aluminum and aluminum alloy products. Our product suite spans across high-performance aluminum alloy industrial profiles, rail transit profiles, aerospace, automotive and Marine profiles, architectural profiles, and curtain wall profiles.
Relying on a vertical setup, our production and processing base operates with an annual output of 15,000 tons of premium aluminum profiles. The infrastructure includes a construction area of 20,000 square meters, housing 90 specialized employees and 5 state-of-the-art extrusion production lines. Among them, our fleet boasts one 1450T extruder, two 700T units, one 2500T unit, and one 1150T unit, allowing for versatile and complex extrusion geometries.
To ensure total reliability for critical defense, marine, and commercial operations, Kangjian has obtained key industry credentials:
IATF16949 Certification for Structural Components
ISO22163 Railway Industry Management System
EN15085, ISO3834 & AWS Welding Compliance
GB/T19001-2016/ISO9001 & GB/T24001/ISO14001
Anodized aluminum profiles are no longer simple extrusions; they are highly customized, multi-functional alloys tailored to specific domestic and international industrial niches. By designing customized profiles, Kangjian answers specific operational requirements:
Unmanned Aerial Vehicles (UAVs) and drones demand extreme weight reduction while keeping structural rigidity. Customized 6061 and 6063 T6 anodized profiles serve as drone structural tubes, offering superior strength-to-weight ratio and resilience to high-altitude oxidation.
Industrial robots and automation platforms rely on precise positioning. Utilizing T-Slot profiles and high-rigidity structural bases, our parts deliver low vibration and dimensional stability to absorb continuous kinetic stresses.
Photovoltaic installations demand frames that can endure harsh outdoor elements (high UV, moisture, salt air) for over 25 years. Deep sulfuric acid anodization ensures a surface layer exceeding 15 microns, defending against premature corrosion.
In Qingdao, a city by the Yellow Sea, a dream about high-end aluminum profiles set sail in 2022. Our founders recognized the domestic demand for sophisticated industrial and marine extrusions. Qingdao, backed by a vast domestic market and facing the international trade waterway, has endowed Kangjian with a unique "dual-sea layout".
"Producing high-end aluminum materials and serving global customers" is our driving philosophy. With cutting-edge equipment, strict quality control, and rapid R&D, Kangjian has transformed its vision into reality. The giant gantry cranes in Nordic ports stand robustly thanks to our high-strength, corrosion-resistant aluminum materials. On drawings for top-tier international projects, the logo of "KANGJIAN ALUMINIUM" shines brightly.
In just three years since its establishment, Kangjian has expanded from its local market to key industrial centers across Anhui, Hebei, Tianjin, Hunan, Guangdong, Beijing, and Jiangsu.
Customized extrusions are delivered for specialized sub-sectors, ensuring precise mechanical attributes for transportation, logistics, and medical equipment.
Utilizing the logistics capabilities of Qingdao Port, our components are exported directly to advanced manufacturing hubs in South Korea, Japan, the USA, and Europe.

Our plant in Qingdao is situated in a high-density industrial zone with robust material access, CNC partners, logistics infrastructure, and surface finishing technologies.
Direct sourcing agreements with premier domestic smelting facilities guarantee consistent billet purity (Fe < 0.15% to prevent anodizing streaks).
Extrusion presses ranging from 700T to 2500T allow for narrow wall profiles and complex hollow configurations alike.
Our average production lead time runs between 14 to 21 days from tooling sign-off to product containerization.
Located in Jimo District, our proximity to the Port of Qingdao supports direct maritime transport and reduced transit costs.
Modern manufacturing demands continuous alignment with global sustainability goals. Aluminum is infinitely recyclable, but reducing energy consumption during the extrusion and anodization stages is critical.
By investing in dynamic induction billet heaters, we minimize energy waste before the extrusion stroke. Our real-time temperature tracking guarantees that the alloy enters the container at the precise metallurgical window.
Traditional nickel-based hot sealing is being replaced by high-performance nickel-free low-temperature sealing systems. This decreases heavy metal footprint and adheres to strict REACH and RoHS restrictions.
To optimize downstream manufacturing, our CNC capabilities allow for immediate integration of counterbores, chamfering, and thread tapping, delivering installation-ready structural elements to end users.
Our lightweight and low-energy products support sustainable innovation across key heavy industries:
Deploying critical components in structural, transit, or electronic fields requires strict certification. Kangjian's manufacturing system meets international testing metrics, ensuring that alloy performance aligns with architectural blueprints and engineering designs:
Each production batch includes a mill test certificate (MTC). Direct emission spectrometer testing confirms alloy compositions meet chemical specifications.
We measure oxide layers using eddy-current instruments, certifying thickness ranges (Class AA10 to Class AA25) in compliance with Qualanod international standards.
We conduct regular testing for salt spray resistance, hardness (Webster & Vickers), and tensile strength on every extrusion batch before shipment.
As a premier global supplier, we resolve typical technical questions raised by structural engineers and procurement heads:
