High-precision manufactured profiles optimized for architectural framing, threshold systems, and structural installations.
Aluminium door sill profiles represent a critical nexus in building envelope engineering. No longer treated as simple transitional metal plates, modern sill designs must serve as highly complex mechanical boundaries. They are engineered to mitigate water ingress, optimize thermal transitions, satisfy structural load criteria, and comply with international barrier-free accessibility guidelines such as the ADA (Americans with Disabilities Act).
Global demand is increasingly driven by strict energy codes. Standard raw solid metal profiles are being replaced with thermal break structures featuring polyamide barriers. These advanced systems limit thermal bridging, reducing internal cooling and heating losses. In parallel, advancements in alloy compositions and surface finishing ensure these profiles retain structural and aesthetic integrity even under high pedestrian foot traffic and harsh environmental conditions.
Established in 2009, Aoli Aluminum is a fully integrated manufacturer of structural and decorative aluminum alloys.
Building Sustainable Cities: We design and produce recyclable, low-carbon aluminium products. Our aim is to achieve environmental alignment and mutual success for our workers, clients, and global business partners.
To lead the sector as the primary choice for aluminum profiles, known for high customer satisfaction, exceptional employee well-being, and a reputable presence in the international export market.
Customer First: Your success defines our benchmarks. We support custom orders with transparent processes and prioritize quality control to protect the reliability of our products.
For procurement officers, general contractors, and industrial developers, sourcing aluminium door sills involves balancing cost, lead times, and structural performance. Large-scale global infrastructure projects require suppliers to meet complex technical demands:
Our engineering services address these technical requirements directly. By managing the process in-house—from initial casting and alloy testing to final high-precision CNC milling—we produce architectural profiles that meet both strict structural requirements and regional building codes.
Operating four production bases equipped with processing machinery to translate custom specifications into high-performance products.
Our plants host extrusion systems ranging from 900 tons to 2,000 tons. This machinery lets us produce shapes across complex geometries and structural dimensions.
We offer diverse finishing services, including: anodizing, electrophoresis, powder coating, PVDF fluorocarbon coatings, and wood grain texturing.
To ensure quick onsite installation, we perform structural drilling, mitering, notch cutting, and counter-sinking on our dedicated CNC processing units.

Modern architectural projects operate on tight schedules, leaving little room for logistics delays or manufacturing errors. Our manufacturing center in Sihui and sales office in Foshan form a well-coordinated supply hub that integrates raw material sourcing, die making, and shipping operations.
By keeping die production, alloy formulation, and secondary CNC processing in-house, we reduce production turnaround times and prevent structural errors. Furthermore, our vertical logistics network ensures prompt shipping through southern China’s major ports, keeping your commercial projects on schedule.
How Aoli Aluminum grew from a local factory in 2009 into an international aluminum profile exporter.
Our founder established our first 10,000-square-meter factory in Sihui, Guangdong, introducing the brand "Aolijie"—which represents quality, industry standards, and high-performance engineering.
We focused on structural research, securing 13 design patents and attaining ISO 9000 certification. This period established our core quality control processes.
To meet rising global demand, we constructed a 100,000-square-meter facility, boosting our annual output capacity to 100,000 tons of architectural and industrial profiles.
After opening our Foshan sales office in 2024, we are establishing our first regional sales office in Malaysia by 2026 to better serve international clients.
Our quality control program is designed to deliver consistent, high-performance profiles. Every production run undergoes complete physical and chemical testing to verify its structural integrity under environmental stress:
We carry out 100% visual checks during production, backed by random AQL sampling (ISO 2859 / ANSI/ASQ Z1.4). Every shipment includes a certified Quality Inspection Report verifying compliance with your order's specifications.
We deliver reliable manufacturing, clear quality control, and competitive pricing for projects of all sizes.
We provide a broad range of standard extrusion profiles. For custom needs, our engineering team refines geometries to optimize performance and control tooling costs.
Our quality checks cover raw billet sourcing through final shipping. We test for tensile strength, dimensional accuracy, coating thickness, and weathering resistance.
Our pricing is built on structural efficiency. Through bulk procurement, in-house tooling, and lean processes, we deliver value without compromising material quality.
Testing methods used to verify safety, durability, and code compliance for all architectural products.
How our customized sill profiles resolve architectural and environmental challenges globally.
For residential builds, our designs focus on thermal insulation and wind-driven rain resistance. Our custom thresholds prevent indoor condensation and drafts, maintaining interior comfort in varying climates.
Retail and office entryways require sills that handle high foot traffic. We supply thick-walled, hard-anodized profiles designed to resist wear and support shopping carts, wheelchairs, and heavy deliveries.
Public infrastructure projects require sills with low profiles and gentle slopes to meet accessibility codes. We design low-clearance thresholds that allow smooth access while managing water drainage effectively.
