Explore our highly-durable extruded structural shapes, thermal heat sinks, and protective casing elements engineered for reliability.
In modern electrical systems and electronics design, the aluminum project box (also referred to as an aluminum enclosure, extrusion case, or instrument housing) serves as a critical barrier protecting delicate internal components from external environmental threats. From industrial automation systems to smart grid controllers, telecommunications hardware, and new energy battery systems, the demand for high-reliability housing options has risen exponentially. Selecting the correct materials, manufacturing tolerances, and surface treatments directly impacts product lifespan, electromagnetic compatibility (EMC), thermal efficiency, and overall system longevity.
The transition toward decentralized smart devices, high-frequency IoT gateways, and high-power electric vehicle battery charging stations requires tough, highly modular packaging systems. Electronics operating in rugged environments—such as marine, mining, oil & gas, and heavy manufacturing—face intense vibrations, chemical exposures, and thermal cycling. Aluminum project boxes constructed using extruded profiles provide mechanical stability, ease of mounting, and structural integrity that sheet metal fabrication or plastic injection molding cannot easily duplicate.
Furthermore, aluminum’s innate electromagnetic shielding capability eliminates the need for expensive secondary coatings, making it cost-effective for compliance with FCC, CE, and industrial EMC directives. By integrating custom heat-sink profiles directly into the enclosure design, engineers can bypass traditional system cooling fans. This reduces structural complexity, eliminates a common point of mechanical failure, and elevates system sealing options up to IP67 and IP68 dust- and water-tight standards.
China is home to the world's most integrated and mature aluminum extrusion supply chain, with Guangdong Province leading in high-precision structural profiles and surface finishing technologies. Key operational advantages driving efficiency include:
When drafting specifications for a custom aluminum project box, several factors must be assessed during the engineering validation phase:
High-capacity manufacturing and strict quality metrics driving global supply chains since 2009.
Aoli Aluminum was established in 2009 and is a manufacturer that integrates research and development, production, and sales. We specialize in the manufacturing of aluminum alloy profiles for construction, decoration, and industry. Our headquarters are located in Sihui, Guangdong, with branch offices in Foshan, Guangdong. A comprehensive ISO quality management system has been established to govern our manufacturing processes.
Our brand is "Aolijie", which owns 4 production bases and is equipped with advanced production lines. This includes extrusion equipment ranging from 900 tons to 2000 tons, surface treatment production lines for powder coating, anodizing, electrophoretic coating, PVDF coating, wood grain, die production, and CNC deep processing equipment, along with a production base for aluminum doors and windows.
Our annual production capacity is 100,000 tons, with over 100,000 sets of our own molds. Our product lines cover more than 100 series and over 1,000 specifications. In order to meet the unique needs of customers and develop customized products, we have adopted internationally advanced technology in thermal break aluminum profiles and precision inspections. Our products are sold to countries and regions such as the Middle East, South America, Africa, and Southeast Asia.

A corporate foundation built upon reliability, customer-first service, and brand reputation.
Building sustainable cities for the world through high-grade aluminum extrusions and structural alloys.
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 building materials industry. During this period, China's urbanization led to rapid growth in building aluminum profiles. Recognizing the environmental, low-carbon, and durable benefits of aluminum profiles for global urban architecture, Mr. Wong established the brand "Aolijie" in 2009.
A standard 10,000 square meter aluminum profile factory was put into production in Sihui City, Guangdong Province, creating the brand "Aolijie".
Implemented strict quality management, obtaining 13 product patents and the ISO9000 certification to ensure consistent structural standards.
Invested in a new 100,000 square meter production facility, scaling annual capacity up to 100,000 tons to satisfy increasing export demand.
Established a dedicated sales branch in Foshan, Guangdong in 2024, with preparations underway to set up an overseas regional office in Malaysia by 2026.
Providing precision engineered components for high-reliability applications globally.
A detailed breakdown of our manufacturing capabilities, pricing structures, and quality standards.
Our priority is customer satisfaction. We offer a selection of standard profiles at competitive rates, alongside a design-to-production workflow for custom profiles that limits tooling or setup costs.
We execute 100% visual inspections and random AQL (Acceptable Quality Level) sampling based on ISO 2859 or ANSI/ASQ Z1.4. Each batch is shipped with a corresponding Quality Inspection Report.
Our pricing model is built on operational efficiency, incorporating vertically integrated manufacturing, strategic bulk raw material procurement, optimized logistical structures, and direct-to-manufacturer pricing.
Each profile batch undergoes rigorous mechanical and chemical analysis before shipping.
