Explore our premium range of precision extruded aluminum profiles engineered for structural integrity, architectural refinement, and heavy machinery parts.
Aluminum sliding doors have moved far beyond standard architectural boundaries. Today's commercial buildings, upscale residential properties, and retail projects require high structural performance, excellent energy conservation, and aesthetic minimalism. Modern sliding doors utilize structural 6063-T5 or 6061-T6 aluminum alloys because they offer the strength needed for narrow frames, providing large, uninterrupted glass layouts that enhance natural light.
Key global development trends focus heavily on integrating smart access systems, improving security parameters to match high standards, and using slim-profile multi-track sliding panels. As real estate development moves toward eco-friendly designs, architectural specs demand structural components that support recycled contents and verify low carbon footprints. This drives innovation across the extrusion supply chain, requiring precise control over alloy purity and extrusion heat treatments.
B2B custom orders require high consistency, prompt delivery, and compliance with certifications. We construct our systems to satisfy strict international benchmarks.
Compliance with ISO9001:2016, ISO14001:2016, and automotive-grade IATF16949 standards ensures consistent metallurgical quality and minimal defect rates across batch runs.
Advanced custom profile shapes are verified with in-house CAD tooling and automated CNC processing to control dimensional tolerances within structural specifications.
With direct proximity to Qingdao Port, our shipping team coordinates secure export bundling and custom customs clearings for North American, European, and Asian shipping lines.
Operating from our 200-mu manufacturing base in Jimo District, Qingdao, Kangjian Aluminum leverages advanced smart manufacturing systems to optimize production. Our facility features five high-capacity extrusion lines, including 2500T, 1450T, 1150T, and dual 700T extruders, allowing us to process diverse profile scales and cross-sections. This specialized machinery provides the mechanical pressure needed to extrude intricate wall configurations with uniform grain structures.
By integrating automation across extrusion, cooling tables, aging ovens, and surface finishing, we minimize manual errors and speed up cycle times. The plant outputs 15,000 tons of high-grade aluminum profiles annually. This production scale, supported by local raw material sources, shields global distributors from sudden supply disruptions and guarantees reliable delivery schedules.

Our custom extruded profiles are engineered to meet specific localized performance criteria across varied climate zones and load expectations.
Founded in 2022, Qingdao Kangjian Aluminum Industry Technology Co., Ltd. has established itself as a leading manufacturer in Shandong Province. Headquartered at No. 168, Tianshan 1st Road, Jimo District, our 200-mu industrial park features 80,000 square meters of production space and 4,000 square meters of office facilities. We specialize in producing aluminum alloy industrial profiles, rail transit profiles, aerospace structural parts, automotive parts, marine sections, and high-performance architectural systems.
Through precise management and processing controls, we have obtained key certifications, including National Industrial Product Production Licenses, GB/T19001-2016/ISO9001, GB/T24001-2016/ISO14001, and IATF16949 Automotive Industry Quality Management System certifications. Our welding capabilities are certified to ISO22163 (railway), EN15085, ISO3834, AWS, and DIN6701 adhesive bonding systems, qualifying us to manufacture high-precision structural products for demanding global projects.
Our manufacturing and processing adhere to strict testing parameters, verified by global classification societies and international quality systems.
Our extrusions are implemented across international ports, marine infrastructure, high-speed rail lines, and commercial high-rises.
Technical information and procurement guidelines for global commercial buyers, engineering firms, and distributors.
We primarily recommend 6063-T5 or 6063-T6 for residential and standard commercial projects due to their excellent surface finish options and high corrosion resistance. For high-wind loads or larger spans, we recommend 6061-T6, which provides higher structural yield and tensile strengths.
We hold certifications for ISO9001 (Quality), ISO14001 (Environmental), and the automotive-grade IATF16949 certification. We also maintain certified processes for structural welding, including EN15085, ISO3834, AWS, and DIN6701 bonding standards.
Our largest 2500T extrusion press can process profiles up to a circumscribing circle diameter of 250mm, depending on structural layout and cross-sectional density. Our smaller presses handle profiles down to 10mm width.
Our electrostatic powder coating lines use automated dosing systems and chemical pre-treatments. Spectrophotometer tests are conducted on every batch to verify color consistency and gloss levels against RAL standards.
Yes. Our CNC division performs precision cutting, milling, drilling, tapping, and assembly, allowing us to supply fully finished structural parts directly to your production line.
Tooling design and mold production typically take 10 to 15 days. Sample approval and initial production runs require an additional 7 to 10 days, depending on profile design and surface requirements.
