Explore our core high-precision structural extrusions engineered for architectural lighting, cleanroom setups, solar integration, and high-performance machinery structures.
Founded and registered in 2022, Qingdao Kangjian Aluminum Industry Technology Co., Ltd. is a leading developer and manufacturer of high-end extruded aluminum profiles, structural parts, and assemblies based in the Jimo District of Qingdao. With a production capability extending across high-precision industrial rails, automotive profiles, marine hardware, aerospace alloy components, and high-performance architectural systems, we serve the most demanding global industrial niches.
Backed by an extensive industrial base spanning 200 mu, our state-of-the-art facility encompasses 80,000 square meters of high-capacity production workshops and a 4,000-square-meter modern engineering center. Currently operating with an annual throughput exceeding 15,000 metric tons of customized aluminum profiles, we maintain a fleet of 5 heavy-duty extrusion lines (ranging from 700T up to a powerful 2500T press line) to support large-scale OEM orders.
Certified with GB/T19001-2016/ISO9001, GB/T24001-2016/ISO14001, IATF16949 (Automotive), ISO22163 (IRIS Railway Industry), EN15085 & ISO3834 (Welding Systems), AWS, and DIN6701 (Structural Adhesive Bonding).
From our strategically located coastal hub in Qingdao, Kangjian Aluminum has expanded its sales footprint to core domestic markets including Anhui, Hebei, Tianjin, Hunan, Guangdong, Beijing, and Jiangsu. Through consistent technical iteration and service reliability, we have grown to be the largest structural aluminum profile manufacturer in the Qingdao region.
Leveraging Qingdao Port's global connectivity, our products are shipped to highly competitive industrial markets in South Korea, Japan, the United States, and across Europe, showing an average annual growth rate of order delivery and output value of 30%.
Linear LED systems generate localized high-temperature stress at the diode p-n junction. When junction temperatures exceed 85°C, phosphor degradation accelerates, lumens decline, and color shifting occurs. High-purity extruded aluminum profiles (primarily utilizing alloy designations 6063-T5 and 6063-T6) act as vital passive heat sinks. With a thermal conductivity rating of approximately 200 W/m·K, these alloys draw heat away from the PCB far more efficiently than plastics or steel.
At our Jimo processing plant, the profile wall thickness and fin geometries are engineered to maximize convective surface area. Clear, architectural, or colored anodization (10 to 20 microns deep) not only provides excellent corrosion resistance but also improves the surface emissivity coefficient, enhancing thermal radiative properties in tight, enclosed environments.
For high-spec architectural and industrial clients, a simple extrusion is rarely enough. Kangjian offers complete downstream processing including precision custom cuts, miter joints, punchings, slots, counter-bored holes, and clean threading. Utilizing our modern vertical milling machinery, we can achieve tolerances down to ±0.1mm.
Surface treatment plays a vital role in light output performance. We offer matte satin anodizing, powder coating in custom RAL finishes, and chemical polishing. Our U-channels can be fitted with snap-in diffuser lenses (Opal, Frosted, and Semi-Clear polycarbonates or PMMA) to control light diffusion, eliminate diode spotting, and optimize light transmission up to 92%.

Operating from Jimo District, Qingdao, Kangjian Aluminum leverages the robust raw material processing ecosystems of Northern China. This gives us access to top-grade, high-purity aluminum ingots at stable pricing structures, insulating our global partners from sudden market shifts.
Proximity to the Port of Qingdao enables efficient container loading, direct custom clearances, and competitive ocean freight rates. With direct weekly sailings to major global hubs, we reduce B2B delivery times by up to 15 days compared to inland Chinese manufacturers.
Tier-1 buyers, contractors, and original equipment manufacturers require consistent raw material tracking, reliable dimension tolerances, and certified production lines. Kangjian meets these needs with structured testing protocols (tensile strength, yield strength, Webster hardness, and anodization layer thickness verification).
Our engineering division accepts standard 2D and 3D CAD models (DWG, STEP, IGES) and develops custom tooling dies in-house. This cuts down testing cycles and lets us move from initial concept drawing to physical sample extrusion in just 10 to 15 business days.
A primary factor setting Kangjian Aluminum apart from standard residential aluminum factories is our focus on high-safety and structural sectors. Our certifications provide assurance to engineering buyers across different industries:
Certified to IATF 16949, ensuring our extrusions meet the strict dimensional, crash safety, and consistency requirements for electric vehicle components and trim.
Certified to ISO 22163 (IRIS), qualifying our production lines to deliver structural elements and lighting ducts for subways and high-speed rail.
Certified under EN 15085-2 and ISO 3834-2. This allows us to supply complex, load-bearing welded structural frames.
Certified to DIN 6701, verifying our bonding capabilities for critical structural assemblies in marine vessels and railways.
