Select, high-grade extruded profiles modified for advanced structural and industrial requirements across major Japanese industrial hubs.
Japan’s industrial sector, renowned for its commitment to high precision, lean manufacturing, and carbon neutrality by 2050, demands structural materials that conform strictly to JIS H4100 standards. Heavy industries, solar power mounting plants, automation facilities in Aichi, and electronics factories in Kyushu are increasingly outsourcing extrusion production to achieve optimal supply chain resilience. High-quality 6000-series (6063-T5, 6061-T6) aluminum alloys are the material of choice for structural frames, heat radiators, and EV battery housings because they combine weight reduction with superior thermal conductivity.
Aolijie addresses these strict standards by combining cost-efficient Chinese production scales with precise testing capabilities. From micro-tolerances (+/-0.1mm) to custom finishes like electrophoretic coating and architectural anodizing, we support Japanese Tier-1 automotive and automation OEMs with consistent, zero-defect batches.

Established in 2009, Aolijie integrates vertical extrusion, die fabrication, advanced CNC deep machining, and global delivery systems.
Headquartered in Sihui, Guangdong, with sales and engineering support in Foshan, Aolijie operates 4 advanced manufacturing bases. Our facilities feature high-capacity extrusion lines (ranging from 900 tons to 2,000 tons) capable of fabricating heavy-duty structural profiles and thin-walled battery enclosures. Through our vertical supply integration, we handle everything from die fabrication to CNC precision post-machining, powder coating, anodizing, electrophoretic coating, and PVDF finishes.
Our Business Vision: Committed to building sustainable, energy-efficient cities, Aolijie strives to deliver reliable industrial profiles while achieving mutual success for our workers, local communities, and global purchasing partners.
Engineered to support heavy industry, smart power grids, and precision electronics integration.
High-strength, crash-tested battery enclosures and chassis supports. Optimized structural weight to help Japanese automakers reach EV mileage goals and improve thermal dissipation in Li-ion battery arrays.
Heavy-duty structural T-slots, T-bars, and multi-cavity framing systems. Anodized surfaces minimize friction wear and simplify structural retrofits in cleanrooms and assembly lines.
Anti-corrosive, PVDF-coated mounting rails and brackets. Specially engineered to resist salt spray, heavy snow loads, and wind shear in coastal Japanese solar installations.
Our brand "Aolijie" represents our long-standing dedication to high-quality aluminum manufacturing. Founded by Mr. Wong, who began working in the construction materials sector in 2000 during a phase of rapid urban growth in China, Aolijie was built on a simple vision: to produce sustainable, durable, and energy-efficient aluminum profiles for global developers.
Deconstructing "Aolijie":
Aolijie established its first 10,000-square-meter facility in Sihui City, Guangdong, installing standard extrusion presses to target the industrial components market.
Achieved ISO 9001 compliance and secured 13 product patents. Developed high-efficiency thermal break profile lines to serve demanding industrial clients.
Invested in a larger 100,000-square-meter facility, raising total annual extrusion output to 100,000 tons to accommodate large-scale international orders.
Opened a dedicated sales branch in Foshan (2024) to manage global accounts, with a regional support office scheduled to open in Malaysia in 2026.
