Engineered to comply with global standards, our top-tier extrusions satisfy the requirements of advanced construction and manufacturing ecosystems.
In the contemporary industrial landscape, the request for structural efficiency, lightweighting, and architectural sustainability has accelerated the reliance on large-scale aluminum extrusions. As a premier Wholesale Large Aluminum Extrusion Manufacturer, Aoli Aluminum (brand "Aolijie") is positioned at the intersection of metallurgy and structural design. We cater to the global demand for profiles that exceed standard extrusion limits, enabling massive modular constructions, aerospace frame elements, rail transport grids, and complex EV battery enclosures.
The shift from multi-part steel assemblies to single, unified aluminum extrusions represents a crucial milestone in optimization. By eliminating joints, welds, and secondary fasteners, large-format extrusions mitigate stress concentrations, reduce assembly cycle times, and optimize structural integrity. Aoli Aluminum integrates raw material sourcing, customized structural design, die manufacturing, high-capacity extrusion, and comprehensive CNC precision fabrication under a single, ISO-certified management flow to ensure high mechanical properties and reliable performance.
Traditional fabrications involve welding individual aluminum parts, which degrades mechanical strength at the Heat Affected Zones (HAZ). Through our high-capacity extrusion lines ranging from 900 to 2000 tons, we eliminate intermediate joining stages, preserving the grain-flow alignment along the length of the profile to offer structural performance with minimal structural weight.
Different industries present varied challenges concerning mechanical stress, thermal dissipation, and corrosion resistance. Our customizable solutions cover architectural building envelopes, heavy industrial machinery, and modern structural frameworks. We supply specialized alloys (such as 6063-T5/T6 and 6061-T6) processed with tailored heat treatments:
| Alloy Profile Group | Key Tempering Options | Ultimate Tensile Strength | Primary Global Application Fields |
|---|---|---|---|
| 6063 Aluminum | T5, T6, T66 | 186 - 240 MPa | Architectural windows, doors, interior walls, and structural curtain walls. |
| 6061 Aluminum | T4, T6 | 260 - 310 MPa | Heavy-duty structural framing, machinery supports, and automotive components. |
| Thermal Break Alloys | Custom composite | Alloy-dependent | Energy-efficient windows, green facades, and extreme weather insulation. |
Decades of operational excellence and investments in advanced metallurgy support our position in global manufacturing.
At Aolijie, we believe that structural integrity must be complemented by surface performance. Extruded profiles frequently undergo hard working environments that require defense against UV damage, acid rain, salt spray, and abrasive wear. Our facilities host state-of-the-art post-extrusion surface treatment lines:

Our structured inspection metrics guarantee that all shipped profiles match design blueprints and structural regulations.
Every component undergoes strict visual inspection for surface defects. Critical metrics, such as profile wall thickness and straightness tolerances, are constantly verified.
We conduct chemical composition analyses on molten alloy batches before extrusion. Tensile testing verifies yield strength, ultimate tensile strength, and elongation limits.
Advanced salt spray chambers and UV aging testers simulate coastal conditions, ensuring our architectural window profiles resist degradation for decades.

LI: "Leading indicator" of high quality and process reliability.
Jie: Transcribed from Chinese, meaning a "master work" of structural integrity.
Established in 2009 by our founder Mr. Wong, Aolijie evolved in tandem with China's urban development. Recognizing the ecological and structural advantages of aluminum profiles, we transition to meet demand for architectural facades, lightweight infrastructure, and heavy transport equipment.
From standard profiles to custom shapes, our engineers guide designs from concept to final assembly.
Clients supply custom cross-sections. Our engineering department uses CAD/CAM modeling to design dies that optimize metal flow during high-pressure extrusion.
Post-extrusion cooling and aging treatments achieve the designated T5 or T6 temper. This step ensures consistent yield strength across the entire profile length.
Our modern CNC processing department cuts, drills, countersinks, and mills components to exact tolerances, ready for assembly upon delivery.
