Explore our high-performance extruded solutions customized to satisfy modern construction standards and complex engineering applications.
Modern building designs demand materials that seamlessly integrate aesthetic versatility with structural performance. Aluminium door jamb extrusions have emerged as the standard for commercial office complexes, residential developments, and industrial cleanrooms globally. Purchasing officers and structural engineers search for suppliers who understand the critical tolerances required for seamless architectural hardware integration.
In highly regulated markets like North America and the European Union, procurement demands extend beyond raw profiles to comprehensive lifecycle compliance. Architects spec door frames requiring strict thermal break technology (such as polyamide barrier strips) to optimize energy envelopes and lower overall building operational costs. Partnering with a vertically integrated factory in China ensures that custom profiles, alloy compositions, and surface treatments comply with standards like AAMA 2605 or Qualicoat Class 3.
Our strategic sourcing model is designed to mitigate supply chain volatility for global contractors. By controlling the entire process from billet casting and die design to final anodizing and CNC machining, we offer predictability in pricing and scheduling, shielding major construction programs from standard material supply bottlenecks.
How our founder's vision transformed local metallurgy expertise into an internationally recognized brand.
The history of the "Aolijie" brand is deeply intertwined with the industrial expansion of aluminum profiles within China. Since 2000, our founder, Mr. Wong, worked closely in the building materials market. During this era of rapid urbanization, he realized that typical materials like timber and raw steel failed to provide the long-term sustainability required by contemporary skyscrapers.
Mr. Wong recognized that aluminum was light, strong, corrosion-resistant, and infinitely recyclable. This inspired a vision to establish a brand that would showcase Chinese engineering precision on a global scale. In 2009, he established the first production facility in Sihui City, Guangdong Province under the brand name "Aolijie".
The name "Aolijie" carries a clear philosophy:
• AO: Combining "A" (the first letter, representing first choice) and "O" (representing optimal option).
• LI: Representing "Leading Indicator" of industry standards.
• Jie: The Chinese term for "Master Work" (杰), indicating high quality.
Today, Aolijie acts as a trusted partner for EPC contractors, real estate developers, and industrial product manufacturers across South America, the Middle East, Africa, and Southeast Asia.
Decades of manufacturing scaling support our capacity to deliver bulk international contracts on time.
Developing sustainable cities for the global market through architectural engineering.
Building sustainable cities for the world. We align our casting, extrusion, and finishing operations with green manufacturing principles to reduce environmental impact.
To remain the extrusion manufacturer with the highest customer satisfaction rating, a great environment for employee development, and a highly recognized Chinese export brand.
Customer First: Customer success is our benchmark.
Brand Reputation: We never compromise product quality and longevity for short-term profits.
An overview of how advanced extrusion profiles are manufactured for structural load-bearing and thermal efficiency.
Aolijie utilizes highly precise automated horizontal hydraulic extruders ranging from 900 tons to 2000 tons. This allows us to manufacture complex geometries for structural curtain walls, multi-track sliding door frames, and custom commercial jamb profiles.
Our engineering team works with structural alloys, primarily 6063, 6061, and 6005, heat-treated to T5 or T6 tempers. By controlling variables such as extrusion speed, billet temperature, and cooling quench rates, we manage grain structure formation to prevent tearing and reduce surface defects prior to finishing.
For high-performance thermal insulation, we integrate PA66 GF25 (polyamide fiberglass-reinforced nylon) thermal break strips. This construction breaks the thermal bridge, reducing heat transfer through the aluminum frame, helping achieve target U-values for green building certifications.
Understanding that environmental factors like coastal salinity and intense UV exposure cause premature fading and corrosion, we provide robust surface protection treatments:
• Anodizing & Electrophoretic Coating: Providing wear-resistant oxide films up to Class I (25 microns) for high-traffic entryways.
• Powder Coating & PVDF: Licensed applying partners of premium resins, offering up to 30 years of resistance to chalking and fading under extreme solar conditions.
• High-Definition Wood Grain: Combining the warmth of natural wood with the structural longevity and minimal maintenance of aluminum.

Our continuous path of capacity scaling, quality certification, and global distribution expansion.
How our laboratory verifies the metallurgy, dimensions, and finishes of every production batch.
To maintain consistent physical properties across structural framing components, Aolijie enforces a multi-tier quality control protocol:
• 100% Full Inspection: Complete visual check for structural straightness and surface blemishes.
• 5% Secondary Spot Checks: Independent QA verification during critical production stages.
• 8 Batch Verification Checks: Every single production run undergoes testing for mechanical properties and dimensional tolerances.
• AQL Sampling (ISO 2859 / ANSI/ASQ Z1.4): Statistically sound sampling protocols that ensure export-ready quality levels.
Our testing laboratory is equipped to verify the mechanical performance and environmental resistance of our profiles. Each product shipment is accompanied by a formal Quality Inspection Report detailing chemical composition, tensile yield strength, and surface finish thickness.
