Explore our core engineering catalog, designed for heavy industrial framing, battery containerization, thermal regulation, and architectural framing systems.
In today's globalized commercial and industrial ecosystem, project enclosures represent much more than simple metal containment systems. The rapid evolution of high-density battery storage, electric mobility, 5G smart infrastructure, and decentralized computing has driven strict structural, thermal, and shielding specifications for modern enclosures.
At Aoli Aluminum (Aolijie), our aluminum project enclosures leverage high-performance Al-Mg-Si alloys (predominantly 6063 and 6061 variants) processed under highly controlled thermal gradients. These materials are engineered to offer high yield strength, outstanding mechanical durability, superior electrical conductivity (for EMI/RFI attenuation), and efficient heat rejection.
Choosing the correct alloy chemical makeup and tempering state is vital for thermal efficiency, surface protection, and weldability in critical projects.
| Alloy Grade & Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Thermal Cond. (W/m·K) | Primary Industrial Applications |
|---|---|---|---|---|
| 6063-T5 / T6 | 186 - 220 | 150 - 170 | 200 - 209 | Complex project enclosures, LED housings, heat sinks, structural framing, wall window profiles. |
| 6061-T6 | ≥ 290 | ≥ 240 | 167 - 180 | Heavy-duty structural elements, automotive chassis components, EV floorboards, and high-load junction boxes. |
| 6005-T6 | ≥ 270 | ≥ 225 | 188 | Railways, marine solar architectures, and high-bending structural awning brackets. |
| 6082-T6 | ≥ 310 | ≥ 260 | 170 | Highly stressed structures, industrial machinery frames, and marine deep-sea components. |
Precision-milled gasket channels with specialized thermal break configurations keep out dust, moisture, and chemical agents in harsh, demanding industrial environments.
Integrated heat sink designs with high fin-to-base ratios enhance passive cooling, reducing core component operating temperatures by up to 15°C without active fans.
In-house vertical milling, drilling, tapping, and mechanical assembly ensure sub-millimeter clearances (+/- 0.02mm) for consistent panel interfaces and tight seals.
The story of our flagship brand, “Aolijie”, reflects the development of aluminum profile manufacturing in Southern China. Since 2000, our founder Mr. Wong worked in building materials. At that time, China's urban development was accelerating, driving demand for sustainable structural elements.
Recognizing that aluminum profiles are a low-carbon, durable material crucial for future cities, Mr. Wong established Aoli Aluminum in 2009. Our brand name reflects this mission:
"Building sustainable cities for the world. Committed to achieving a win-win situation for employees, customers, and society has always been our business vision."
Over 15 years of structured growth, patent acquisitions, and capacity scale-ups.
A standard 10,000 m² extrusion facility was established and put into operation in Sihui, Guangdong Province. Mr. Wong registered the "Aolijie" brand, laying the foundation for local raw material integration.
Implementing rigorous production standards, the factory secured 13 design patents and established its ISO9000 quality management certification to stabilize component output.
To support growing global demand, Aolijie constructed a new 100,000 m² automated manufacturing base. This expansion boosted annual production capacity to 100,000 tons.
Established a centralized sales and design branch in Foshan, Guangdong. Aolijie is currently setting up a regional logistics office in Malaysia in 2026 to support South-East Asia and Western supply lines.
Aolijie project enclosures protect critical electrical and electronic systems across challenging global environments.
Deployed extensively across high-humidity coastal and arid desert installations. Features corrosion-resistant thick PVDF or anodized protective coatings (15-25μm) to prevent oxidation from salt spray and dust erosion.
Providing custom extruded sub-assemblies for electric vehicle floorboards and high-capacity battery cell containment. Engineered to handle mechanical shock and aid heat dissipation under high electrical load.
Heavy machinery structures built with multi-slot profiles ensure secure cable routing, clean workspaces, and reliable mechanical protection for control systems.
Operating out of Sihui and Foshan in Guangdong, Aolijie benefits from a highly integrated aluminum supply chain. This clustering coordinates raw material sourcing, mold fabrication, heat treatment, extrusion, surface finishing, and secondary CNC machining within a tight geographic area.
This consolidation allows us to minimize transportation overheads, quickly scale up production volume, and offer direct-from-factory pricing.
Each batch undergoes testing based on ISO 2859 and ANSI/ASQ Z1.4 to verify dimensional tolerances, chemical purity, and finish durability.

Aolijie's research and development focuses on three primary areas for the next generation of project enclosures.
Integrating mechanical routing and mounting tracks into the profiles to accommodate environmental and temperature sensors in smart city structures.
Developing structural profiles using certified post-consumer scrap to lower the embedded carbon footprint for international building standards.
Developing custom extruded heatsink profiles using high-purity aluminum matrices to optimize thermal transfer in high-power converters and chargers.
Expert answers to common engineering questions regarding raw material selection, manufacturing tolerances, and surface treatments.
We recommend 6063-T6 for complex extruded enclosures due to its balance of structural strength, ease of extrusion, and excellent response to anodizing. For high mechanical stress, 6061-T6 offers greater yield strength, though it is slightly more difficult to extrude into complex profiles.
We process gasket channels during extrusion or via post-extrusion CNC milling. When paired with high-performance silicone or EPDM gasket profiles, these tight mechanical interfaces prevent ingress of dust and water under low-pressure immersion conditions.
For coastal installations, we recommend PVDF coating or Class 2 Anodizing (minimum thickness of 20 microns). These finishes provide excellent barrier protection against chloride ions, preventing cosmetic pitting and structural corrosion.
Standard tooling and sample production takes approximately 10 to 14 days, depending on profile complexity. Tooling fees are typically credited back once production volumes reach agreed-upon thresholds. Our vertically integrated facilities help minimize overall setup costs.
Yes, all Aoli Aluminum extrusions and surface treatments are lead-free and conform to EU RoHS and REACH requirements. We provide complete material certification and chemical analysis documentation for every production batch.
