Aoli Aluminum integrates research and development, smart extrusion production, and downstream sales under our core brand "Aolijie". Specializing in high-performance aluminum alloy profiles for construction, heavy decoration, and modern industrial automation, we operate our main production facilities in Sihui City, Guangdong, with sales branches located in Foshan, Guangdong.
Our strict ISO 9001 quality management system guarantees that every extruded profile achieves the highest levels of dimensional accuracy, surface integrity, and metallurgical consistency. Our primary vision remains building sustainable cities for the world while maintaining double-win structures for employees, global buyers, and the environment.
"Our mission is building sustainable cities for the world. Committed to achieving a win-win situation for employees, customers, and society."
Aolijie operates across 4 massive production bases, delivering raw extrusion and fine CNC deep-processing under one unified management system.
Equipped with advanced extrusion presses ranging from 900 tons to 2000 tons, managing complex cross-sections and large architectural facades. We specialize in deep multi-cavity and ultra-thin hollow profiles.
In-house lines for high-durability Powder Coating, Anodizing, Electrophoretic Coating, PVDF coating, and simulated wood grain. Engineered for C5-level corrosion resistance and long outdoor exposure.
Going beyond raw extrusions to provide CNC drilling, milling, high-precision cutting, tapping, and window-door system fabrication. We deliver ready-to-assemble mechanical modules directly to your production lines.
With an annual output of 100,000 tons of premium aluminum profiles, Aolijie maintains an extensive library of over 100,000 sets of existing molds. Our product range spans across 100 series and 1,000 separate customer specifications, which drastically reduces tooling costs and shortens lead times for new engineering projects.
For complex thermal requirements, we use advanced thermal break profile technologies and high-precision inspection rigs that test down to the micrometer level. Our products are exported to the Middle East, South America, Africa, and Southeast Asia, offering robust structural foundations for multiple projects worldwide.
A global industrial footprint driving efficiency, reliability, and precision across architectural and manufacturing sectors.
Our founder, Mr. Wong, began his journey in the construction materials industry in 2000. He witnessed the rapid expansion of modern cities and realized the ecological value of lightweight, durable, and highly recyclable aluminum. Today, Aolijie represents this vision: offering high-grade Chinese engineering solutions to global infrastructure projects.
Our primary 10,000 square meter factory commenced operations in Sihui, Guangdong. We launched the brand "Aolijie" to design and supply industry-leading standard aluminum profiles.
Implemented strict ISO9001 standards, securing 13 key product patents, particularly in structural framing improvements and high-efficiency thermal breaks.
To keep up with growing market demand, we invested in a new 100,000 square meter plant, scaling up our annual output capacity to 100,000 tons.
We established a sales branch in Foshan to support key international trading routes. In 2026, we are launching an overseas regional office in Malaysia to streamline local supply chains across Southeast Asia.
AO: The letter "A" represents leading performance (No.1), and "O" stands for Option. Together, "AO" signifies the "First Choice."
LI: "L" stands for Leading, and "I" stands for Indicator. Together, "LI" represents the "Leading Indicator" of quality.

Aolijie: Your First Choice — outstanding Chinese products guided by industry-leading indicators.
Aolijie also provides architectural aluminum profiles, including thermal-break sliding door profiles and modern glass curtain wall frames.
Aolijie ensures all raw materials and custom parts undergo rigorous testing. We maintain a zero-defect policy backed by full physical and chemical analysis.
Our quality control process is built on 100% full visual inspection and strict statistical AQL (Acceptable Quality Level) sampling, using international standards like ISO 2859 or ANSI/ASQ Z1.4. This ensures consistent mechanical properties, precise dimensional tolerances, and high surface finish quality across every batch.

A comprehensive technical overview for industrial buyers, procurement managers, and systems design engineers.
Guangdong operates as the absolute hub of global aluminum extrusions. Operating our manufacturing bases in Sihui and Foshan grants Aolijie instant access to premium primary aluminum ingots, specialized alloying components, and world-class tooling facilities. This geographical clustering cuts transportation times for auxiliary treatments and reduces tooling and custom die development cycles. Together with the nearby ports of Guangzhou and Shenzhen, we ensure fast, reliable shipping to international industrial hubs.
Navigating import regulations requires strict document accuracy. Aolijie supplies complete chemical composition test records, Mill Test Certificates (MTC), dimensional reports, and certificate of origin documents. All products comply with international environmental directives, including RoHS and REACH. By establishing localized representative networks, such as our branch in Malaysia, we resolve import compliance questions and provide localized technical support for structural designers in Southeast Asia and Europe.
Industrial aluminum profiles must perform reliably in demanding structural environments. In automated production lines, multi-slot T-slot and V-slot framing provides high structural rigidity under dynamic loads, allowing engineers to construct modular enclosures and machine guards without welding. For renewable energy systems, lightweight, weather-resistant structural channels protect sensitive lithium battery packs on rough roads, while highly conductive anodized alloys serve as efficient heat sinks for industrial electronics.
The global industrial profile market is shifting rapidly toward carbon neutrality and smart manufacturing. Low-carbon green aluminum, refined using renewable energy, is becoming a primary specification for eco-conscious enterprises. Structurally, manufacturers demand profiles with higher strength-to-weight ratios, such as 6082-T6 and 7000-series alloys, to improve structural efficiency. Additionally, integrated CNC deep processing is standardizing, allowing buyers to source fully finished parts that bypass raw stock storage.
Expert answers addressing alloy grades, manufacturing tolerances, custom mold design, and surface treatments.
For most standard industrial and structural frames, Alloy 6063-T5 or T6 is the industry standard due to its excellent surface finish, ease of extrusion, and moderate strength. For heavy-duty applications requiring higher structural load capacity, such as support gantries or machine frames, we recommend Alloy 6061-T6 or 6082-T6, which offer superior tensile and yield strength.
We work to standard dimensional tolerances aligned with GB/T 14846 or EN 755-9. With precision extrusion dies and advanced production control, we can maintain high-precision tolerances down to ±0.15mm on critical dimensions, depending on the cross-section geometry. Tighter tolerances can also be achieved through post-extrusion CNC machining.
Anodizing electrochemically builds up the natural oxide layer, creating a hard, corrosion-resistant surface. We offer anodizing thicknesses ranging from Class 10 (10 microns) for normal indoor use up to Class 15/20 (15-20 microns) for harsh industrial or outdoor marine environments. This protection prevents oxidation and maintains long-term structural integrity.
Once the design drawing (CAD/3D model) is approved, we construct the custom extrusion tooling within 7 to 10 days. Sample profiles are extruded and sent to the client for validation. Following sample approval, full production begins, with average lead times ranging from 15 to 20 days depending on order volume.
Yes. We use advanced thermal strip insertion machines to join inner and outer aluminum sections with reinforced polyamide (PA66-GF25) strips. This process creates high-strength, energy-efficient thermal barrier profiles that meet modern building insulation regulations.
To prevent scratches and damage during transport, profiles are wrapped with protective PE film or interleaved with soft paper. Bundles are then secured in heavy-duty cardboard boxes, shrink-wrapped, and loaded into reinforced wooden crates or steel frames for safe handling by forklifts at destination ports.
