Explore our foundational range of premium custom extrusions, engineered for modern architecture, solar mountings, and battery thermal management.
U-section aluminium extrusions (widely designated as U-channels or architectural channels) represent one of the most versatile geometric profile shapes in modern engineering. By forming a solid base and two perpendicular vertical walls, U-sections provide exceptional structural rigidity, lightweight capabilities, and anti-corrosive properties, making them indispensable for architectural, electrical, industrial, and automotive assemblies.
At Aoli Aluminum, we manufacture high-performance U-channels primarily utilizing 6000-series aluminum alloys (specifically 6063-T5, 6063-T6, and 6061-T6). These alloys provide an optimal balance of structural strength, superior surface finish options, and excellent corrosion resistance. Whether utilized as glass track channels for frameless curtain walls, structural brackets in automated assembly lines, or thermal containment housings for lithium battery packs, our profiles are fabricated with rigorous adherence to global manufacturing tolerances (such as EN 755 and ASTM B221 standards).
Below is a summary of standard technical attributes and mechanical parameters of our extruded aluminum U-sections.

From heavy civil engineering to thermal structures in high-tech vehicles, U-section profiles act as structural framing elements.
Aluminum U-sections serve as crucial dry-jointing tracks and perimeter anchoring matrices for glass panes in commercial double-glazed or frameless curtain wall assemblies. Our structural components absorb seismic loads and wind pressures while providing thermal breaks.
The battery enclosures of electric cars require lightweight, rigid chassis protection. Deep-processing aluminum U-channels protect lithium pack matrices against lateral crashes, while serving as high-performance integrated liquid-cooling conduits.
In utility-scale PV plants, corrosion-proof aluminum U-beams withstand harsh atmospheric environments. The optimized structural design of extruded tracks ensures quick mounting slide connections and high strength-to-weight performance.
U-section extrusions act as linear guiding tracks, structural protection rails, and wiring channels in automated production plants, ensuring continuous load capacity and smooth travel paths for mechanical components.
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 mission is building sustainable cities for the world. Committed to achieving a win-win situation for employees, customers, and society has always been our business vision. We operate 4 advanced production bases equipped with high-tech automated extrusion systems, ranging from 900 tons to 2000 tons. This allows us to manufacture complex geometries and custom configurations with precision tolerances.
Our surface treatment facilities include state-of-the-art lines for powder coating, anodizing, electrophoretic coating, PVDF coating, and wood grain processing. We also feature high-precision CNC deep processing centers to cut, drill, punch, and mill profiles to exact design requirements, alongside a dedicated production base for premium aluminum doors and windows.
Since the initial expansion of the Chinese building materials industry, the Aolijie brand has evolved into an international supplier of high-quality profiles.
A standard aluminum profile factory covering 10,000 square meters was 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, establishing our technical credentials in the regional marketplace.
Responding to positive market feedback, we invested in the construction of a 100,000 square meter factory in 2017, increasing our annual production capacity to 100,000 tons of high-grade profiles.
In 2024, we established a sales branch in Foshan, Guangdong. To better support our overseas buyers, we are setting up our first dedicated international office in Malaysia in 2026.
A look inside our extrusion lines, aging furnaces, powder spraying booths, and warehouse storage hubs.
Our components are divided into two main categories: Architectural Building Profiles and High-Spec Industrial Profiles.
Our customized architectural and industrial solutions are deployed globally in modern curtain walls, infrastructure, and custom industrial framing systems.
Quality is our top priority. We implement 100% full inspection alongside random AQL sampling to verify structural and cosmetic integrity.
Optical emission spectrometry checks chemical composition limits for Si, Mg, Fe, and Cu elements before billet casting.
Destructive testing verifies ultimate tensile strength, yield strength, and elongation percentage of aged profiles.
Webster and Vickers hardness tests confirm that tempering stages achieve the specified mechanical properties.
Digital projection and calliper testing confirm cross-sectional dimensions, wall thicknesses, and twist tolerances.
Cross-cut tape testing and thickness gauges check coating thickness and film adhesion on powder-coated and anodized surfaces.
Accelerated environmental testing evaluates the corrosion resistance of surface treatments for coastal applications.
Ultraviolet exposure testing evaluates color retention and gloss stability for outdoor building profiles.
Our facilities run under validated environmental and manufacturing processes, meeting ISO standards for global export.
Guangdong Province stands as the world's premier cluster for aluminum extrusion manufacturing, providing unique advantages in efficiency and custom tooling.
Our Sihui and Foshan manufacturing clusters house billet casting, die development, hot extrusion, surface finishing, and CNC precision machining within a 20-kilometer radius. This integration minimizes internal logistics costs, improves quality control, and shortens turnaround times.
Unlike factories that outsource mold making, our tooling department maintains complete control over die geometry and nitriding processes. This capability allows us to manufacture complex custom profiles in 7 to 10 days, while keeping tooling costs low.
Located near major deepwater ports in Guangzhou and Shenzhen, we offer efficient international shipping options. Our logistics team handles export documentation, customs clearance, and anti-dumping compliance to ensure smooth delivery.
Aoli Aluminum is committed to decarbonization and smart manufacturing technologies to meet global environmental requirements.
We are expanding the use of certified post-consumer recycled (PCR) scrap aluminum in our raw material supply. By recycling scrap, we reduce carbon emissions by up to 85% compared to primary smelting, helping customers meet scope 3 carbon reduction targets.
We are integrating real-time infrared temperature sensors and automated air/water quenching tables across our extrusion lines. This technology ensures consistent heat treatment profiles and uniform mechanical properties throughout the entire run.
To comply with RoHS and REACH regulations, we have transitioned our pre-treatment processes to chrome-free chemical conversion coatings, ensuring our products are safe for building and automotive applications.
We are committed to providing you with the highest quality products and excellent services. If you have any questions or need assistance with our products, please feel free to contact us and we will be happy to serve you.
