Providing Precision-Extruded Aluminum Profiles & EV Enclosures Engineered for Central Europe’s Dynamic Automotive, Photovoltaic, and Industrial Automation Systems
Designed for Brno's and Prague's advanced industrial networks. Offering lightweight components that comply with stringent European mechanical standards.
The Czech Republic is a powerhouse of European manufacturing, with the industrial sector contributing more than 30% of the national GDP. From the historic automotive clusters in Central Bohemia to the high-tech machinery development corridors in Brno and Pilsen, local companies demand mechanical components that are structurally sound and light. Modern engineering designs are shifting away from heavy steel fabrications toward high-tensile, extruded aluminum profiles.
For Czech Tier-1 automotive manufacturers and assembly line system builders, structural integrity and tight tolerances are critical. The use of custom aluminum profiles allows designers to reduce vehicle weight, simplify frame construction, and streamline component integration. Alloys such as EN AW-6060, 6063, and 6082 are key materials, balancing strength, weldability, and corrosion resistance.
Globally, the demand for precision aluminum extrusions is driven by the shift toward renewable energy and electric vehicles (EVs). In Europe, regulations like the Corporate Sustainability Due Diligence Directive (CSDDD) force manufacturers to source components with lower carbon footprints. Aluminum's infinite recyclability makes it the ideal material for green initiatives. Whether it is battery housings for urban micro-mobility fleets or structural frames for utility-scale photovoltaic tracking systems, extruded aluminum provides the mechanical performance required for long-term outdoor operation.
Established in 2009, Aoli Aluminum (brand "Aolijie") operates four production bases equipped with advanced extrusion lines ranging from 900 to 2,000 tons. Our primary headquarters is located in Sihui, Guangdong, with sales branches in Foshan, giving us direct access to high-grade raw materials and advanced deep-processing facilities. With an annual capacity exceeding 100,000 tons and an inventory of over 100,000 custom die sets, we support Czech and global engineering firms in taking custom profiles from concept to final product with competitive lead times.
At Aoli Aluminum, our core mission is building sustainable cities for the world. We combine state-of-the-art aluminum extrusion technologies with CNC precision machining, anodizing, powder coating, and thermal break assembly lines. Our facilities operate under strict ISO 9001 and ISO 14001 guidelines to ensure that every shipment matches client specifications.
Our vertically integrated production process spans raw material alloy analysis, die design and manufacturing, heating, billet extrusion, quenching, straightening, precision cutting, and surface treatments. This structure allows us to offer competitive direct-to-factory pricing and maintain strict control over quality, from billet chemistry to finished surfaces.
We provide a comprehensive range of building systems and custom industrial profiles, designed to meet the technical needs of modern engineering projects.
Ensuring compliance with international quality standards. We conduct complete mechanical and chemical testing on every batch before shipment.
Spectrographic analysis guarantees the exact ratio of silicon, magnesium, manganese, and iron in every alloy batch.
Testing yield strength, tensile strength, and elongation limits to verify structural safety margins for loaded profiles.
Using digital micro-calipers and profile projectors to achieve tolerances as tight as +/- 0.1 mm, matching original drawings.

A comprehensive range of custom structural components, mounting frames, and enclosures, optimized for import into the Czech market.
Sourcing structural components requires a balance between dimensional stability and production cost. Standard catalog profiles often fail to meet the performance criteria of complex builds, demanding custom profile configurations. By optimizing the metal distribution in cross-sections, structural designers can increase load-carrying capacity while reducing weight.
Guangdong's industrial clusters provide key supply chain advantages for international buyers, particularly in Europe. The consolidation of raw material sourcing, die tooling design, extrusion, and surface treatment in one hub lowers production overhead. Aoli Aluminum leverages this regional setup to offer custom extrusion solutions with fast turnaround times and competitive tooling costs.
Furthermore, our in-house surface treatment lines—specializing in anodizing, PVDF coating, and powder coating—provide durable protection against weather and mechanical wear. For industrial environments in the Czech Republic, where exposure to humidity, dust, and temperature swings is common, our surface finishes ensure long service life and minimal maintenance.
We manage shipping and customs clearance for European imports, offering options from CIF main European ports (like Hamburg or Koper) to DDP inland destinations in Ostrava, Prague, or Brno. Our quality management system complies with ISO 9001 and ISO 14001, and we provide material test reports (MTRs) and conformity declarations for European industrial operations.
Answers to common questions from project engineers and procurement managers in Central Europe regarding custom aluminum profiles.
Our aluminum profiles are extruded in compliance with European standards, including EN 755 (for mechanical properties and tolerances of extruded profiles) and EN 12020 (for high-precision profiles in alloys 6060 and 6063). This ensures compatibility with European framing systems and components.
Yes. We have an in-house tooling workshop where we design and manufacture custom dies based on your CAD files (.DWG, .DXF, .STEP). For qualified orders, the die cost can be refunded once the purchase volume reaches agreed thresholds.
We recommend alloy 6063 for battery cases and heat sinks due to its thermal conductivity (approx. 200 W/m·K) and excellent surface finish. For structural components requiring higher load-bearing capacity, we recommend alloy 6082-T6 or 6061-T6, which offer superior tensile strength.
Each production run undergoes spectroscopic testing for chemical composition, Webster hardness testing, and dimension checks. We follow ISO 2859-1 standards for sampling and visual inspection, and we provide material test certificates (EN 10204 Type 3.1) with each delivery.
Standard tooling setup and initial sample approvals take 10 to 14 days. Production of bulk orders typically requires 20 to 25 days. Shipping to Central Europe via ocean freight to Northern ports (e.g., Hamburg, Rotterdam) or Southern ports (e.g., Koper) takes approximately 35 days, followed by rail or truck transit to your facility.
Yes. Beyond basic extrusion, we offer CNC precision cutting, drilling, tapping, milling, and assembly. This allows you to receive ready-to-assemble profiles directly at your production lines, saving processing time and reducing local waste.
