Explore our primary range of architectural and high-durability framing profiles, certified to global standards and engineered for maximum load efficiency.
Aluminum profiles, specifically the 4040 series (40mm x 40mm), serve as the structural backbone of modern automated industries. Their cross-sectional architecture provides an optimal strength-to-weight ratio, allowing engineers to build durable frameworks without the weight penalties of structural steel. Our standard 4040 profiles feature an 8mm T-slot, allowing them to accommodate standard M8 fasteners, t-nuts, and brackets for rapid, modular assembly.
From metallurgical composition to extrusion dynamics, the quality of a 4040 extrusion relies on precise temperature control during manufacturing. At Aoli Aluminum (Aolijie), we employ premium 6063 and 6061 alloy grades, heat-treated to T5 or T6 tempers. This delivers superior yield strength, structural stability under dynamic load, and excellent corrosion resistance. For projects requiring thermal isolation, our specialized thermal break systems prevent heat transfer, ensuring energy-efficient performance in building envelopes.
"By employing state-of-the-art extrusion technologies and strict ISO quality guidelines, we ensure that every millimeter of our 4040 aluminum extrusion complies with the narrowest tolerance requirements (DIN EN 12020-2), ensuring seamless modular alignment."
In today's volatile global procurement landscape, supply chain resilience is as critical as material quality. Operating from our state-of-the-art facilities in Sihui and Foshan, Guangdong Province, Aoli Aluminum integrates smart manufacturing principles to assure absolute scalability, competitive pricing, and shortened lead times.
By controlling the entire process from alloy billet melting and casting to mold design, complex extrusion, surface finishing, and CNC deep processing, we eliminate third-party delays. This direct vertical integration ensures direct-to-manufacturer pricing and unified quality accountability.
Located in the heart of South China's industrial hub, we command exceptional bargaining power for raw aluminum ingots. Our long-term hedging strategies and large-scale bulk procurement stabilize materials cost, shielding international clients from drastic raw material price spikes.
We believe in absolute transparency. With over 27 production stages monitored in real-time, our extrusion floor, chemical anodizing pools, PVDF coating areas, and high-precision CNC deep cutting centers are always ready for customer inspections.
As structural demands evolve, Aoli Aluminum is pushing the boundaries of metallurgical science to ensure superior structural performance. The chemistry of our extrusion alloys (6063 vs 6061) is micro-controlled to minimize iron impurities and maximize dispersion hardening phase formations.
By implementing strict melting and casting filtration (ceramic foam filters), we control alloy chemistry to dynamic engineering tolerances. The standard 6063-T5 profile offers a yield strength of ≥110 MPa and tensile strength of ≥160 MPa, whereas 6061-T6 provides heavy-duty capacities of ≥240 MPa yield strength for structural load centers.
To withstand extreme environments, we offer five distinct surface options:
For architectural applications, we integrate high-strength polyamide (PA66-GF25) thermal barriers. This breaks heat conduction paths within window profiles, curtain walls, and building envelopes, contributing to carbon-neutral construction policies globally.
The 4040 aluminum profile is not merely a generic component; it is an industrial catalyst. Different industries demand distinct structural parameters, load distributions, and surface traits. Below is how we map 4040 extrusion attributes to global macro-industrial standards.
Used for factory automation frameworks, conveyor side guards, and pick-and-place gantry systems. Demands absolute dimensional straightness (< 0.5mm/m) and slot wear resistance to preserve sliding joint alignments.
Outdoor application dictates high resistance to wind-shear and galvanic corrosion. Our 4040 profiles receive heavy clear anodizing (Class I, >15µm) to resist salt spray and acid rain degradation.
Electric vehicle applications demand profiles with high thermal dissipation capacities. Aoli's precision heat sink extrusions optimize thermal conductivity via micro-fin surface profiles.
Pharmacies, laboratories, and cleanroom framing require clean, non-outgassing finishes. Smooth anodized 4040 profiles with matching plastic caps prevent particulate collection.
Our brand "Aolijie" is closely related to the development of aluminum profiles in China. Since 2000, our founder Mr. Wong has been engaged in the sales of building materials industry. At that time, China's real estate was in a rapid development trend, marking the official start of China's building aluminum profile industry.
Aluminum profiles are an environmentally friendly, low-carbon, sturdy, and durable material. Mr. Wong was keenly aware of the significance of aluminum profiles for future urban architecture, which will surely benefit the world. Therefore, the dream of producing high-quality aluminum profiles emerged from then on.
"A" is the first of all letters and has a No.1 meaning, while "O" refers to "option", so "AO" means "First choice".
"L" refers to "leading", "I" refers to "indicator", so "LI" means "leading indicator".
"jie" means "master work" in Chinese, signifying our dedication to craftsmanship and engineering excellence.
Therefore, "Aolijie" is: your first choice - outstanding Chinese products guided by industry-leading indicators.
In 2009, a standard aluminum profile factory covering an area of 10,000 square meters was established and put into production in Sihui City, Guangdong Province. The brand "Aolijie" was founded, dedicated to producing industry-leading standard aluminum profiles.
Based on strict requirements for product quality and production management, we obtained 13 product patents and ISO9000 certification between 2010 and 2016.
Due to positive market feedback, we invested in the construction of a 100,000 square meter factory in 2017, increasing our annual output capacity to 100,000 tons.
In 2024, we established a sales branch in Foshan, Guangdong. To facilitate local technical support and faster distribution in Southeast Asia, we will establish our overseas branch office in Malaysia in 2026.
Quality is not a slogan; it is a measurable science. Aoli Aluminum maintains an ISO-certified testing laboratory. Every extrusion run undergoes a strict testing regime to guarantee absolute compliance with client blueprints and mechanical stress requirements.
To achieve zero-defect delivery, our QC teams apply a layered check structure:
Componential Analysis
Tensile Test
Hardness Test
Dimensional Measurement
Coating Test
Salt Spray Test
UV Aging Test
For international tier-1 buyers, importing structural components from China requires strict shipping, packaging, and regulatory alignment. Aoli Aluminum ensures that all global corporate orders are delivered with zero customs friction and under full packaging compliance.
Standard 4040 extrusions are often raw. We provide deep downstream processing including high-precision cutting (±0.2mm), milling, thread tapping, slot drilling, countersinking, and pre-assembly of joint subsets to minimize labor on your factory floors.
Our upcoming sales & logistics hub in Malaysia (set for 2026) offers localized technical consultation, rapid tooling prototyping, and tariff mitigation strategies. We support global compliance regulations including RoHS, REACH, and LEED green building requirements.
To avoid moisture damage and physical denting during container shipping, we apply custom export packing. Each profile is wrapped in anti-scratch protective film, bundled with heavy craft paper, and packed in reinforced, IPPC-certified wooden crates.
