Kangjian
Maximizing structural durability requires precise alloy compositions. For premium casement window designs, the standard is 6063 aluminum, engineered for smooth extrusion finishes and excellent anodizing properties. For critical structural wind loads, 6061-T6 profiles provide high tensile strength (up to 290 MPa) and yield capacity, ensuring reliable durability in high-rise coastal developments.
Modern building envelopes require strict energy efficiency. High-performance thermal break casement windows feature custom-extruded polyurethane insulation blocks or polyamide (PA66GF25) strips. By separating the interior and exterior aluminum profiles, this design lowers overall U-factors, controls condensation, and delivers reliable thermal insulation for cold climates.
Architectural aluminum profiles must withstand UV radiation and corrosive coastal environments. Anodized coatings with a thickness of 15 to 25 microns protect against oxidation. Alternatively, powder-coat systems meeting AAMA 2604/2605 certifications offer long-term color stability, salt-spray resistance, and protection against chalking in harsh environments.
Located in the Jimo District of Qingdao City, Qingdao Kangjian Aluminum Industry Technology Co., Ltd. was established in 2022. Our facilities cover an area of 200 mu, with 80,000 square meters of production space and 4,000 square meters of office buildings. We specialize in producing aluminum and aluminum alloy industrial profiles, railway systems, aerospace parts, automotive and marine components, and custom architectural curtain walls.
Our facility features a production capacity of 15,000 tons of aluminum profiles per year, supported by 5 advanced extrusion lines. Our machinery line includes one 1450T extruder, two 700T extruders, one 2500T unit, and one 1150T unit. This setup allows us to manufacture complex profile shapes with tight dimensional tolerances.
We are the largest aluminum profile manufacturer in the Qingdao area. We specialize in components for high-speed railways, subways, automotive structural parts, marine engineering, and energy-saving building envelopes. We design products to support lightweight engineering, low emissions, and sustainable development.
In just three years, Qingdao Kangjian Aluminum Industry has expanded from regional supply channels to serving international industrial markets. Our distribution network reaches beyond Shandong to core industrial areas in Anhui, Hebei, Tianjin, Hunan, Guangdong, Beijing, and Jiangsu. Leveraging Qingdao's logistics port infrastructure, our high-end architectural and industrial profiles are exported to South Korea, Japan, North America, and Europe.
Despite market volatility, we maintain an average annual growth rate of 30% in order delivery and output volume. This growth is driven by our manufacturing quality control, custom design services, and responsive international supply chains.
Qingdao Kangjian was founded along the Yellow Sea to address the demand for high-end aluminum extrusions. By combining coastal shipping routes with modern machinery, we bridge the gap between architectural design and industrial aluminum processing.
Our corporate mission, "Producing high-end aluminum materials and serving global customers," drives our operations. Our components are used in projects worldwide, from industrial cranes in Nordic ports to architectural curtain walls in major cities. We design and deliver each profile to support global engineering projects.
We implement strict quality standards across all production stages, from raw billet selection to final packing. Every batch of extruded profiles is tested for alloy chemistry, dimensional accuracy, wall thickness, and finish quality.
We offer flexible logistical configurations, custom engineering services, and technical support to assist our clients with material selection, die modification, and international compliance certification.
We supply railway extrusions for high-speed rail systems, carriage structures, and heavy load profiles. By reducing dead weight while maintaining structural safety margins, our alloys help lower energy consumption in mass transit networks.
Our heavy-duty, corrosion-resistant anodized solar mounting frames and PV brackets are engineered to withstand high wind loads and harsh marine atmospheres, ensuring the long-term reliability of renewable energy systems.
We manufacture custom CNC-machined robotic arms, structural mounts, and sensor brackets. Our lightweight, dimensionally stable profiles reduce mechanical inertia and improve accuracy in automated factory assembly lines.
