Direct from Aolijie's State-of-the-Art Extrusion Facility in Sihui, Guangdong
T-Aluminium profiles, also structurally categorized as T-slot or T-track extrusions, form the core framework of modern modular industrial design, automation robotics, and heavy-duty frame assemblies. These components feature a continuous, T-shaped groove along one or multiple faces. This standardized architectural channel permits modular components, bracket systems, and fastening hardware to slip into the profile, securing structural elements together without structural welding.
By utilizing high-grade 6000-series structural alloys (principally 6063-T5, 6063-T6, or 6061-T6), T-slot frames deliver structural strength-to-weight ratios superior to standard mild steels. The profile's cross-sectional geometry is optimized to resist bending and torsional deformation, rendering it the standard choice for architectural cladding support systems, CNC gantry routers, automated conveyor systems, cleanroom partitions, and commercial window wall assemblies.
From Local Building Material Supplier to Global Extrusion Brand
The story of "Aolijie" is tied to the industrialization of aluminium metallurgy in southern China. Our founder, Mr. Wong, began his journey in 2000 in the construction materials market. Sensing a long-term global shift toward low-carbon, durable, and recyclable building frameworks, he established a specialized manufacturing plant in 2009 in Sihui City, Guangdong.
The name "Aolijie" reflects our operational philosophy:
AO (First Choice): To be the preferred partner for architects and developers.
LI (Leading Indicator): Setting the benchmark in dimensional accuracy and alloy strength.
JIE (Masterpiece): Ensuring every structural extrusion is treated as a masterwork of engineering.
Sihui factory opens with a 10,000 m² footprint, specializing in structural window profiles and standard T-slot extrusions.
Awarded 13 design and chemical utility patents. Receives ISO 9001 and ISO 14001 certificates for quality management and environmental compliance.
Invests in a 100,000 m² smart manufacturing base, boosting output to 100,000 metric tons per year with automatic powder coating and anodizing lines.
Launches a dedicated international trade division in Foshan. Setting up an ASEAN support center in Malaysia in 2026 to assist regional projects.
How Our Profiles Support Key Industries Globally
T-slot profiles serve as the foundation for industrial robotic cells, material sorting stations, assembly lines, and conveyor side rails. The profiles permit simple mounting of sensors, safety switches, and pneumatic actuators directly into the slots, reducing system integration costs.
Anodized T-slot profiles are widely used in cleanroom partitions for pharmaceutical and electronics manufacturing. They do not outgas or harbor particulates. Our heavy-duty industrial T-profiles also serve as structural components for utility-scale solar tracker systems.
Used in unitized curtain walls, louvers, and commercial window systems. T-shape profiles handle wind loads, control thermal transfer via polyamide barriers, and support heavy double-glazed units without excessive deflection.
From Raw Billet to Micro-Precision CNC Machined Component
We melt and cast raw A00-grade aluminum ingots into 6063, 6061, and 6082 alloy billets. This ensures strict control over silicon (Si), magnesium (Mg), and iron (Fe) ratios for optimum mechanical properties.
Our 4 production bases run 900-ton to 2000-ton hydraulic extrusion presses. Billets are heated to 450°C–500°C and forced through custom-engineered dies to produce accurate profile cross-sections.
Profiles are cooled via air or water quench and stretched for straightness. They are heated in aging ovens to achieve the required hardness temper (T5, T6, or T66) and high yield strength.
We offer custom surface finishes: anodizing (clear or color), electrophoresis, electrostatic powder coating (Qualicoat certified), and PVDF coatings for long-term corrosion resistance.
Aolijie's production bases in Sihui and Foshan, Guangdong, place us at the center of the world's most dense aluminium industrial cluster. This proximity grants us direct access to raw materials, die tooling houses, and surface finish processing suppliers.
Our vertical integration—covering die design, extrusion, surface finishing, and CNC post-machining under one system—eliminates intermediate markups and shipping delays. This optimization allows us to offer competitive pricing without taking shortcuts on alloy composition or quality control.
100% Inspection & Testing Framework for Demanding Industrial Projects
To guarantee structural consistency, every batch of Aolijie T-profiles is subjected to a strict quality check. This includes a 100% visual surface inspection, a 5% secondary spot check (8 spot checks per batch), and random AQL sampling based on ISO 2859-1 or ANSI/ASQ Z1.4.
