Engineered for robust mechanical applications, structural facade solutions, and high-performance architectural systems.
In modern structural engineering and commercial architecture, the demand for high-integrity components has positioned aluminum extrusion doors at the center of construction planning.
Driven by international thermal efficiency policies (such as Europe's Energy Performance of Buildings Directive and USA's ASHRAE standard 90.1), real estate developers and industrial contractors are seeking advanced doors with high structural integrity and thermal resistance. Modern projects demand materials with high strength-to-weight ratios, low lifecycle costs, and excellent recyclability.
Aluminum extrusion doors utilize premium 6000-series alloys, particularly 6063-T5 and 6063-T6, to provide high wind-load resistance and durability. Advanced surface treatments—such as architectural anodizing, PVDF fluorocarbon coatings, and cleanroom-grade powder coatings—ensure these door systems survive demanding chemical and environmental conditions without structural degradation.
Pioneering sustainable, precision-manufactured aluminum extrusions for international structural and decorative markets since 2009.
Established in 2009 in Sihui, Guangdong, Aoli Aluminum operates state-of-the-art production bases with advanced extrusion presses ranging from 900 tons to 2000 tons. This tooling enables production of complex hollow shapes and thick structural profiles for commercial doors, thermal barrier window sections, and heavy industrial framing.
Our in-house capabilities include high-durability powder coating, hard-coat anodizing, high-gloss electrophoretic coatings, multi-coat PVDF fluorocarbon coatings, and premium wood-grain transfer systems. This variety allows buyers to specify the finish required for their local environment, whether coastal salt air or heavy industrial exposure.
With over 100,000 sets of existing molds covering more than 100 product series and 1,000+ technical configurations, we accelerate turnaround times for global clients. If a project requires proprietary door frame configurations, our engineering team can design custom extrusion dies, manufacture tooling, and provide samples quickly.

An engineering analysis of material selection, heat treatment, tolerances, and quality control systems for high-performance doors.
For aluminum extrusion doors, selecting the correct chemical composition is essential for long-term performance. We primarily utilize Alloy 6063 and Alloy 6060. Alloy 6063 contains magnesium (Mg) at 0.45–0.9% and silicon (Si) at 0.2–0.6%, creating a magnesium-silicide ($Mg_2Si$) compound. When heat-treated to the T5 or T6 temper, this structure improves mechanical performance while maintaining ease of extrusion.
T5 temper is produced by cooling profiles directly from the extrusion press followed by artificial aging. For higher stress demands, T6 profiles undergo solution heat-treatment and artificial aging. This increases tensile strength to a minimum of 205 MPa (29,700 psi) and yield strength to 170 MPa (24,600 psi), ensuring the doors resist deformation under high structural loads.
Modern environmental policies require high thermal performance in exterior openings. Our thermal break profiles feature glass-fiber reinforced polyamide strips ($PA66\ GF25$) inserted into dedicated extrusion cavities. This creates an insulated barrier that separates the interior and exterior aluminum frames, reducing thermal conductivity through the metal.
By using polyamide strip technology, we achieve a low heat transfer coefficient (U-value) of less than $1.6\ W/(m^2\cdot K)$ in typical sliding and hinged door applications. This design also permits two-tone color options, allowing different finishes on the interior and exterior surfaces to match project requirements.
To ensure smooth assembly and operation of lock systems, multi-point latches, and hinges, we work to tight manufacturing tolerances. Our products are extruded in accordance with EN 755-9 and ANSI H35.2 standards. CNC deep machining includes precision cutting, punching, slotting, and countersinking to meet exact tolerances of $\pm 0.1mm$, preventing installation errors and alignment issues on site.

Connecting professional expertise with global architectural demand.
In the early 2000s, during a period of urban expansion in China, our founder, Mr. Wong, worked in building materials sales. Observing the growth of real estate and commercial construction, he recognized that lightweight, high-strength, recyclable aluminum profiles would be key to future sustainable infrastructure.
In 2009, Mr. Wong established our production facility under the brand name "Aolijie". The name represents our core business principles:
Our first 10,000 square meter factory was opened in Sihui, Guangdong. We registered the "Aolijie" brand and focused on standard structural extrusions for regional projects.
We implemented strict quality controls, secured 13 engineering patents, and obtained ISO 9001 certification. This period laid the groundwork for exporting to international markets.
To meet rising export demand, we constructed a 100,000 square meter production facility. This upgrade raised our annual capacity to 100,000 metric tons of aluminum profiles.
We established a sales and logistics branch in Foshan, Guangdong. To better support international projects, we are opening our first overseas office in Malaysia in 2026.
Practical guidance for developers, contractors, and door distributors sourcing from China.
Verify that your supplier provides mill test certificates (MTC) for each batch. Cheap scrap aluminum can contain iron impurities that lead to micro-cracking and corrosion. Our raw billets consist of pure A00 grade aluminum, providing consistent strength and surface finish.
Custom profiles require dedicated tooling. Choosing a factory with an extensive catalog of existing dies (such as our 100,000+ sets) can save thousands in tooling costs and reduce production setup times by 7 to 15 days.
Surface damage during shipping is a common issue. We wrap profiles in protective poly-film, bundle them with heat-shrink wrapping, and pack them in wooden crates. This packaging ensures the aluminum doors arrive in excellent condition.
Extruded door systems engineered for specific mechanical, structural, and environmental conditions.
High-traffic entrance doors require robust construction. Our heavy-duty extruded profiles are designed for continuous use, supporting large glass panels and modern door-closer systems.
Key Alloy: 6063-T6Controlled environments demand smooth surfaces that are easy to clean and resist chemicals. Our flush-profile door frames are finished with architectural-grade powder coatings that withstand sanitation routines.
Key Finish: Chemical Resistant Powder CoatResidential projects in coastal areas require protection from salt air. Our door extrusions are treated with a Class 25 anodized layer or PVDF finish to resist corrosion and pitting over time.
Key Finish: Class 25 Anodizing / PVDFEvery production batch undergoes inspection and mechanical testing to verify performance prior to shipping.
