Established in 2009, Aoli Aluminum has developed into an industry-leading manufacturer that seamlessly integrates research and development, design, metallurgy, extrusion, and precision machining. Our primary focus is the manufacturing of high-performance architectural, decorative, and industrial aluminum alloy profiles.
Headquartered in Sihui, Guangdong, with our strategic sales hub located in the manufacturing capital of Foshan, we operate dynamic extrusion lines and comprehensive fabrication infrastructure. We have built a robust ISO 9001 quality management system to guarantee every profile leaving our facility exceeds international standards. Our brand "Aolijie" stands as a symbol of structural reliability, design versatility, and precision alignment across residential and commercial building applications.
With comprehensive processing capability from billet smelting to finished frame modules, Aolijie ensures structural integrity and dimensional tolerance at every juncture. Our multi-stage operations accommodate challenging configurations for modern high-wind and high-isolation door openings.
Our brand "Aolijie" manages 4 production bases equipped with state-of-the-art extrusion lines (900 tons to 2000 tons capacity). We offer premium surface treatments including anodizing, powder coating, electrophoresis, PVDF coating, and warm wood grain heat transfer.
Using advanced thermal break profiles containing structural polyamide PA66-GF25, we address modern thermal performance regulations. Customized product configuration uses high-precision tooling and computer-assisted coordinate checks.
Our profiles and architectural systems are trusted across South America, the Middle East, Southeast Asia, and Africa. Over 100 series and 1,000 active configurations adapt easily to local climatic, mechanical, and safety regulations.
For structural components like door sashes, transoms, and heavy mullions, structural reliability depends on the underlying metallurgy. China aluminum profile door manufacturers largely utilize 6000-series (Al-Mg-Si) alloys, specifically 6063 and 6061. 6063 provides excellent extrudability, corrosion resistance, and high-quality surface finishes, making it ideal for architectural trim. For heavy commercial storefronts or high-traffic entrance systems, 6061 and 6005A alloys provide superior mechanical properties, including higher yield strength and shear limits. Proper artificial aging (tempering to T5 or T6) ensures stable mechanical properties that withstand cyclic stresses and thermal expansion without structural fatigue.
Aolijie applies architectural surface finishes strictly aligned with Qualicoat and Qualanod standards. Anodizing thickens the natural oxide barrier, yielding a surface hardness that resists abrasion and galvanic corrosion. For high-humidity coastal settings, our 3-coat PVDF (Fluorocarbon) coatings provide resistance to salt spray, humidity, and UV radiation, ensuring color retention over decades. Electrostatic powder coatings are available in a range of RAL colors, allowing architects to match building envelopes while maintaining weatherability.
Profile walls are engineered with internal reinforcement ribs at points of maximum stress. Under wind loads, door profiles experience deflection. By recalculating the Moment of Inertia (Ix and Iy) using CAD structural simulation, Aolijie optimizes profile cross-sections. This allows us to reduce weight while resisting wind loads of up to Class 8 (GB/T 7106), ensuring safety in high-rise constructions.

Modern energy conservation guidelines demand window and door systems maintain low U-factors. Uninsulated aluminum profiles conduct heat quickly, leading to temperature loss and condensation. To prevent this, Aolijie uses advanced structural thermal barriers.
Aolijie utilizes PA66-GF25 (25% glass fiber reinforced polyamide) thermal break strips, inserted and rolled between the inner and outer aluminum skins. The glass fiber reinforcement matches the thermal expansion rate of aluminum, preventing structural shear fatigue over decades of use. These thermal barriers reduce thermal conductivity, allowing our door systems to meet European Passive House requirements (U-value under 1.4 W/m²K depending on the glazing).
By integrating multi-chamber polyamide barriers and high-performance EPDM gaskets, our systems insulate against thermal energy loss, draft infiltration, and external noise. This makes our profiles suitable for high-density office blocks, hotel projects, and residential buildings in extreme climates.
| Profile System Type | Typical U-value (W/m²K) | Condensation Risk |
|---|---|---|
| Standard Non-Thermal Break | 5.8 - 6.2 | High |
| Single-Chamber Thermal Break | 2.2 - 2.8 | Medium |
| Aolijie Multi-Chamber PA66 | 1.2 - 1.6 | Extremely Low |
Every geographical region presents unique challenges. China aluminum door manufacturers must engineer profiles that withstand these diverse climatic demands.
Under intensive sunlight, standard coatings can fade and degrade. Aolijie customizes profiles with super-durable Qualicoat Class 2 powders and PVDF coatings, resisting temperatures up to 80°C. Heavy-duty dust seal gaskets prevent fine desert sand from entering sliding tracks.
Cold climates demand thermal separation to prevent heat loss. Our profiles feature wide PA66-GF25 thermal breaks that accommodate triple-glazed insulated units, achieving thermal values that support green building compliance.
Coastal architecture faces salt air corrosion and high wind pressures. Aolijie profiles use seawater-resistant pre-anodizing treatments under architectural powder coats. Heavy structural walls withstand the wind load pressures common in storm regions.
Building sustainable cities for the world. We are committed to achieving a win-win situation for employees, customers, and society, making it our business vision.
• Be the aluminum profile production enterprise with the highest customer satisfaction.
• Be the Chinese aluminum profile enterprise with the strongest sense of employee happiness.
• Be the most influential Chinese aluminum profile export brand.
• Customer First: Regard customer success as our responsibility.
• Employee Development: The result of joint efforts between the company and employees.
• Brand Reputation: Nothing can sacrifice brand reputation.
Our brand "Aolijie" is closely linked to the development of aluminum profiles in China. Since 2000, our founder, Mr. Wong, has been engaged in the building materials industry. During this period of rapid urban expansion, he recognized the value of aluminum profiles as an environmentally friendly, durable material for future cities. In 2009, he established our dedicated manufacturing plant in Sihui, Guangdong, under the brand name "Aolijie".

T5 temper profiles are cooled directly from high-temperature shaping and then artificially aged, which is suitable for standard architectural window frames. T6 temper profiles are solution heat-treated and artificially aged, providing higher mechanical properties and yield strength. This makes them ideal for structural elements like large sliding door mullions and high-traffic storefront sashes.
Polyamide PA66-GF25 (reinforced with 25% glass fiber) shares a similar thermal expansion coefficient to aluminum. This prevents shear stress and separation during extreme temperature fluctuations. PVC has a different expansion coefficient and lower mechanical strength, which can lead to structural failure when used in heavy-duty storefront door systems.
For environments with high salinity, we recommend PVDF (fluorocarbon) coating or marine-grade powder coating with a pre-anodized base. This combination protects the aluminum substrate from filiform and pitting corrosion caused by salt exposure.
We produce profiles in compliance with European standard EN 12020-2 and Chinese national standard GB/T 5237. Our quality control lab uses coordinate measuring machines and digital calipers to check critical dimensions, ensuring seamless installation of glazing and gaskets.
Once CAD drawings are approved, mold fabrication and testing takes 7 to 10 days. We run test extrusions to verify profile dimensions before proceeding with full production.
Yes, Aolijie engineers custom thermal break profiles with widths from 14.8mm up to 24mm. Wide, multi-chamber polyamide struts allow systems to accommodate thicker triple-glazing units to meet strict U-value specifications.
