Explore our selection of heavy-duty industrial frames, thermal break casement designs, and precision aluminum components.
A comprehensive breakdown of dimensions, load limits, structural calculations, and mechanical applications.
The 4080 (40mm x 80mm) profile is engineered for heavy duty loads. With a moment of inertia of approximately Ix = 74.50 cm⁴ and Iy = 20.30 cm⁴, this system provides unmatched rigidity compared to standard 4040 structural profiles.
Manufactured using high-strength 6063-T5 or T6 structural aluminum alloy. Provides minimum yield strength of 160 MPa and tensile strength of 215 MPa, ensuring compliance with global building codes and ISO criteria.
Treated with clear or black anodization conforming to MIL-A-8625 standards (film thickness ≥ 10 microns). Also available with PVDF coatings for marine-grade atmospheric exposure protection.
For a 1-meter span of 4080 T-slot profile supported at both ends, a central point load of 400 kg will result in a deflection of less than 1.5mm. This makes it the ideal structural profile choice for dynamic CNC frames, automated manufacturing cells, heavy safety cages, and custom industrial workbenches requiring strict dimensional stability.
Aoli Aluminum was established in 2009 and is a manufacturer that integrates research and development, production, and sales. We specialize in manufacturing of aluminum alloy profiles for construction, decoration, and industry. Our headquarters are located in Sihui, Guangdong, with branch offices in Foshan, Guangdong, and a comprehensive ISO quality management system has been established.
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 is 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.
Your first choice for high-precision, industry-leading structural systems.
"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", and "I" refers to "indicator", so "LI" means "leading indicator".
"Jie" represents "master work" in Chinese, representing high craftsmanship and flawless industrial manufacturing.
From melting raw billets to precision CNC cutting, Aoli manages the entire cycle under strict compliance.
Our industrial extrusion setups range from 900 tons to 2000 tons of press capacity. This allows us to manufacture complex geometries, wide curtain walls, and dense structural profiles like the 4080 series without structural defect vulnerability.
To support high-end global projects, we possess dedicated surface treatment facilities, including:
We do not just extrude; we provide fully fabricated parts. Our CNC facility operates precision mills capable of structural drilling, counterboring, pocket milling, threading, and angle-cutting of 4080 structures to your exact blueprint tolerances (±0.1mm).
Our product covers more than 100 series and over 1000 specifications, sold to global regions including the Middle East, South America, Africa, and Southeast Asia. We adopt internationally advanced technologies in thermal break structures and precision testing.
Why procurement teams choose our Sihui and Foshan manufacturing clusters for custom structural profiles.
Our facilities handle billet casting, extrusion die design, extrusion, surface finishing, and CNC post-machining in-house. This cuts out intermediary shipping, shortens turnaround to 15-20 days, and prevents component handling scuffs.
Located in Guangdong's elite aluminum hub, we source premium ingots and components with minimal domestic logistics delay. Proximity to major export shipping ports (Guangzhou, Shenzhen) guarantees efficient maritime freight rates.
With 100,000+ mold sets ready for production, we minimize the necessity of custom die fabrication. When a custom layout is required, our internal toolmakers construct precision dies at a fraction of Western costs, facilitating fast prototyping.
Global procurement teams must balance unit costs with compliance requirements. We structure our systems to ensure smooth integration into foreign industrial facilities:
A history of continuous growth, technological innovation, and expanding global market footprint.
A standard aluminum profile factory covering an area of 10,000 square meters was established and put into production, located 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 to 100,000 tons.
In 2024, we established a sales branch in Foshan, Guangdong, and will set up an overseas office in Malaysia in 2026 to support direct global logistics and localized business.
Engineered for versatility across heavy industrial, electronic, green energy, and structural automation applications.
Used to construct linear actuator frames, custom 3D printer skeletons, industrial robotic bases, and factory conveyors where rigidity and linear motion tracks are required.
Highly suited for medical fabrication spaces and pharmaceutical cleanrooms because of the non-corrosive, easy-to-sanitize anodized surface of the 4080 profile.
Reflecting our heat sink production competence, these profiles are modified into high-power cooling elements for electric vehicle drive components and structural protective cases.
Each production batch undergoes testing inside our ISO-certified inspection labs before leaving our loading docks.

The role of architectural extrusions in sustainable development goals.
Aluminum is crucial in modern green building initiatives. Extruded frames function as structural elements while optimizing thermal barriers. By integrating thermal breaks into window and door assemblies, Aolijie systems reduce building heat exchange, resulting in lower HVAC carbon footprints.
Our manufacturing utilizes pure primary ingot inputs alongside managed recovery loops. Because structural aluminum can be recycled infinitely with no loss in mechanical strength, choosing extruded 4080 systems contributes directly to regional LEED and BREEAM certifications.
Addressing the technical, logistics, and design queries of global industrial buyers and mechanical engineers.
Aoli Aluminum provides a diverse line of architectural trim, decorative panels, and structural hardware to match our profile extrusions.
