Explore our leading architectural and industrial solutions engineered for durability, exact tolerances, and premium aesthetics.
Black aluminium profiles represent a core element in modern architectural design and high-tech industrial manufacturing. The application of matte black, satin, and deep gloss black finishes goes far beyond aesthetic value. In the fields of electronics cooling, solar support systems, vehicle battery enclosures, and LED linear lighting, black surfaces play an essential role in optimizing thermal performance, weather resistance, and UV stability.
From an engineering perspective, the choice of the correct black finish determines the product lifecycle. Anodized black profiles utilize an electrochemical process to build a stable aluminium oxide layer that integrates directly with the substrate, preventing flaking and peeling. Meanwhile, advanced powder coating processes protect the metal against high moisture, industrial pollution, and chemical exposure, meeting international architectural quality guidelines.
Aoli Aluminum was established in 2009. We are 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 is "Aolijie", which owns 4 production bases and is equipped with advanced production lines, including extrusion equipment ranging from 900 tons to 2000 tons. Our surface treatment capabilities cover powder coating, anodizing, electrophoretic coating, PVDF coating, wood grain sublimation, die production, and CNC deep processing equipment. We also operate a production base dedicated to aluminum doors and windows.
Our annual production capacity is 100,000 tons, with over 100,000 sets of our own molds. Our products 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.
Achieving structural reliability and long-lasting black finishes requires compliance with global chemical and physical standards.
We work mainly with 6000-series alloys, especially 6063, 6061, and 6082, providing the balance between mechanical properties and surface finish. The chemical composition is strictly verified using spark emission spectrometers to prevent impurities that could ruin anodized finishes.
For architectural installations, our black finishes comply with Qualicoat (for powder coating) and Qualanod (for anodizing) requirements. Anodized coatings maintain a thickness of 15 to 25 microns to ensure high corrosion resistance and color stability under solar radiation.
Global procurement teams must meet environmental restrictions. Aolijie ensures all black surface finishes are lead-free and chromium-free. They also comply with REACH regulations, making them safe for indoor applications and commercial buildings.
China leads the world in aluminum processing, offering a highly integrated supply chain that spans from raw bauxite refining to precision CNC machining. As a supplier located in Sihui and Foshan, Guangdong—the center of China's aluminum extrusion industry—Aoli Aluminum benefits from local material sourcing, skilled technicians, and optimized shipping connections.
We operate 4 production bases, allowing us to manage the entire manufacturing cycle. This structure eliminates third-party markups, maintains quality control at every stage, and shortens turnaround times. This operational efficiency is the reason we can provide custom black aluminum extrusions at highly competitive prices without compromising on quality or mechanical performance.
Quality is our top priority. We implement a strict verification program to ensure every extrusion batch meets architectural and industrial standards.
Verifies alloy chemical composition to ensure exact structural performance.
Measures yield strength, ultimate tensile strength, and elongation limits.
Checks Webster and Barcol hardness to confirm the tempering state (T5/T6).
Uses digital calipers and optical comparators to verify tight tolerances.
Measures coating thickness and tests adhesion to prevent chipping.
Tests the corrosion resistance of black profiles under salty, coastal environments.
Ensures black finishes resist UV degradation and maintain their color without fading.
The name "Aolijie" represents our core commitment: First Choice - Outstanding Chinese products guided by industry-leading indicators.
Representing the first letter and first choice, marking our drive to be the leading option for our global clients.
Signifying leadership ("L") and the indicators ("I") that establish manufacturing excellence within the sector.

We regard customer success as our responsibility. Our primary vision is to be the aluminum profile production enterprise with the highest customer satisfaction.
We believe that growth is the result of joint efforts between the company and employees, working to build the happiest workplace.
Our reputation is our most valuable asset. We never sacrifice quality standards or reputation for short-term financial gains.
Our founder, Mr. Wong, who had been in the building materials industry since 2000, established a 10,000 square meter factory in Sihui, Guangdong. We launched the "Aolijie" brand to supply high-quality, standard profiles.
During this period of growth, we focused on strict quality management, obtaining 13 product patents and achieving ISO9001 certification.
Following strong market demand, we invested in building a new 100,000 square meter factory in 2017, increasing our annual production capacity to 100,000 tons.
We opened our sales branch in Foshan, Guangdong in 2024 to support export clients, and we are opening our first overseas branch in Malaysia in 2026.
Aoli Aluminum designs custom black anodized and powder-coated extrusions for diverse environments, architectural layouts, and heavy industries.
Black-coated housings protect EV battery cases, light rail fittings, and heat sinks. The non-reflective finish provides high thermal emissivity, improving heat dissipation in dense spaces.
For frameless curtain walls, window profiles, and outdoor pergolas, our PVDF and anodized coatings provide long-term weather resistance, preventing fading under high UV index conditions.
For 4040 structural assemblies, electronics racks, and factory automation structures, our matte black anodized coating provides a scratch-resistant finish for high-wear environments.
