Direct access to our engineered structural profile systems, customizable extrusions, and specialized architectural solutions.
Aluminium square profiles—often designated under international alloy configurations such as 6063-T5, 6063-T6, and 6061-T6—represent the structural backbone of modern structural engineering, industrial automation, and architectural curtain walls. Unlike standard hollow structural steel (HSS), extruded aluminium offers an exceptional strength-to-weight ratio, high ductility, inherent corrosion resistance, and precise dimensional tolerances.
The metallurgical attributes of the 6000-series alloy system, characterized by the addition of Magnesium (Mg) and Silicon (Si), allow for complex extrusion geometries with internal ribs, multi-slot configurations, and thermal breaks. By optimizing the extrusion speed, die tooling parameters, and quenching medium (air or water), manufacturers can achieve tailored mechanical specifications. For instance, T5 tempering offers excellent surface finish suitability for anodization, while T6 tempering yields a higher tensile yield strength (minimum 240 MPa for 6061-T6) essential for heavy industrial framing.
The international industrial landscape is witnessing a structural migration towards sustainable structural design. Key commercial drivers include:
As compliance frameworks like the European Union's Carbon Border Adjustment Mechanism (CBAM) phase in, procurement managers are prioritizing factories that utilize energy-efficient melting systems, optimized scrap recovery loops, and verified ASTM/EN certifications. Supply chain resilience has transitioned from a cost-only analysis to a localized risk mitigation strategy, prioritizing manufacturers with extensive raw material reserves and vertically integrated extrusion-to-machining pipelines.
Founded in 2009, Aoli Aluminum (brand name: Aolijie) has evolved into an industry-leading manufacturer specializing in architectural, decorative, and industrial aluminum alloy profiles. Our corporate headquarters are located in the high-tech industrial zone of Sihui, Guangdong, complemented by global sales and technical consulting branches in Foshan.
Building sustainable cities for the world. We design products that reduce thermal transmission, optimize raw material utility, and lower the carbon footprint of global infrastructure projects.
To be the aluminum profile production enterprise with the highest customer satisfaction globally, acting as the premier Chinese export brand recognized for technical accuracy and product integrity.
Customer First (regard customer success as our responsibility), Employee Development (the joint evolution of workforce and corporate systems), and Brand Reputation (zero compromises on quality standards).
The brand name "Aolijie" reflects Mr. Wong's commitment to industrial excellence established during the early real estate boom in 2000:
Established a standard 10,000 sq. meter extrusion plant in Sihui, Guangdong. Launched the "Aolijie" brand to focus on premium commercial profiles.
Obtained 13 independent product patents and secured comprehensive ISO 9001/9000 management and quality system certifications.
Expanded facilities to 100,000 sq. meters, scaling annual productive capacity to 100,000 metric tons to support major international infrastructure projects.
Inaugurated international sales hubs in Foshan (2024) with upcoming logistics and support operations scheduled for Malaysia in 2026.
Aoli Aluminum implements a highly vertically integrated manufacturing process that mitigates supply chain disruptions and ensures dimensional precision. By keeping all operations—from chemical composition mixing to final CNC deep processing—within our direct controls, we manage quality and costs more efficiently.
Equipped with a suite of heavy hydraulic extrusion presses ranging from 900 tons to 2,000 tons. This ensures consistent density and straightness tolerances conforming to EN 755-9 specifications.
Full-scale automated chemical processing tracks: Electrostatic Powder Coating, Acid/Alkaline Anodizing, Electrophoretic Coating, PVDF Fluorocarbon coatings, and architectural wood-grain finishes.
Secondary machining capabilities including precision multi-angle mitre cutting, high-speed drilling, localized tapping, structural milling, and hardware insertion for plug-and-play assembly.
Explore our continuous manufacturing floor, extrusion lines, die inventory, and logistical dispatch bays.
We employ a strict quality control system that includes 100% visual inspection on anodized/painted finishes and random AQL (Acceptable Quality Level) sampling based on ISO 2859-1 or ANSI/ASQ Z1.4. This ensures that every shipment meets structural and dimensional tolerances before dispatch.
To verify compliance across European EN standards and American ASTM guidelines, our testing laboratory performs systematic chemical and mechanical verification for every production run.
Quality parameters verified on each lot:
• 100% Visual Surface Inspection for handling lines, die lines, and inclusions.
• 5% Secondary Spot Audits conducted at localized packing lines.
• 8 Structural Testing Points per extrusion batch.
• Traceable Material Quality Inspection Reports issued with chemical melt IDs.
Optical Emission Spectrometry (OES) to verify accurate Mg, Si, and Fe ratios in the raw ingot melt.
Verification of ultimate tensile strength, yield strength, and elongation limits under load.
Webster hardness tester verification to ensure correct tempering (T5/T6).
Caliper, micrometer, and projection system measurement to confirm mechanical drawings.
Eddy current thickness checking and cross-hatch adhesion testing on painted profiles.
Corrosion testing under ASTM B117 standards to confirm paint/anodization layer durability.
Accelerated UV light exposure tests to guarantee color retention on outdoor coatings.
