Explore our primary selection of modular anodized configurations designed for high-strength automated lines, architectural frames, and precise mechanical positioning.
In modern structural engineering, modularity has transitioned from a design choice to a critical requirement for speed, adaptability, and cost optimization. The 30 Series Aluminum Profile (30mm base dimension with 6mm or 8mm slot width options) represents the ultimate structural equilibrium. It fills the space between light-duty applications (20 series) and heavy-duty structural grids (40 series and larger).
Historically, assembly lines, automated machinery, and safety enclosures depended on welded steel frames. This method introduced heat distortion, required continuous protective coatings, and eliminated any chance of rapid reconfiguration.
The 30 series, manufactured under strict tolerances at Chengdu E&I Aluminum Industry Co., Ltd., offers an alternative. Featuring anodized protective films, specialized cross-sectional moments of inertia, and standardized slot configurations, these profiles allow for fast construction using simple mechanical connections. The result is a structure that is shock-resistant, highly durable, and easily adaptable to changing layouts.
Selecting the correct profile requires analyzing the exact structural and dimensional parameters of the 30 series family. The table below outlines key dimensions, slot widths, and typical applications across our portfolio:
| Profile Model | Dimensions (mm) | Slot Width | Surface Treatment | Primary Industrial Applications |
|---|---|---|---|---|
| ENI-8-3030F | 30 × 30 | 8.2 mm | Anodic Oxide | High-Strength Machinery Frames & Robot Bases |
| ENI-8-3030R | 30 × 30 (Round corner) | 8.2 mm | Clear Anodized | Safety Fences, Display Units, Ergonomic Corners |
| ENI-6-3030G | 30 × 30 | 6.2 mm | Lightweight Anodized | Easy-to-Machine Light Lab Frames & Sensor Brackets |
| ENI-8-3030M / ME | 30 × 30 | 8.2 mm | High-Precision Anodized | Engineering Automation Lines & Cleanroom Enclosures |
| ENI-8-3060 | 30 × 60 | 8.2 mm | Modular Design Anodized | Clean Sheds, Weld Stations, Medium-Duty Gantries |
| ENI-8-3090 | 30 × 90 | 8.2 mm | Heavy Anodization | Electromechanical Enclosures & Multi-Axis Shifters |
| ENI-8-30120 / 30150 | 30 × 120 / 30 × 150 | 8.2 mm | Heavy-Duty Modular | Heavy Load-bearing Struts, Structural Automated Rails |
Our profiles feature anodic coatings of 10 to 15 microns. This provides high surface hardness, protects against atmospheric corrosion, and minimizes scratches during assembly.
Available in 6mm (lightweight) and 8mm (heavy-duty) variants. Standardized slot profiles are designed to match international fastener standards for secure, vibration-resistant connections.
Profiles are manufactured to strict straightness tolerances, ensuring exact alignment. This makes them ideal for precision automation lines and linear rail integration.
From smart factories in Europe to assembly facilities in Southeast Asia, modular aluminum profiles form the backbone of modern automated infrastructure.
Working with major international automotive brands, our modular aluminum profiles are widely used for assembly line frames, protective barriers, and robotic cell structures. The non-magnetic properties of aluminum also prevent interference with welding equipment and electrical systems.
In semiconductor manufacturing and biotechnology, particle contamination must be avoided. Anodized 3060 and 3090 modular profiles do not shed particles, resist corrosion from cleaning agents, and provide clean, modular support structures for air filtration systems.
Aviation hangars and assembly zones require strong, lightweight structures for maintenance platforms, heavy tool racks, and protective shielding. Our high-strength alloys provide the required structural integrity while remaining light enough for manual handling.

The manufacturing industry is shifting toward more sustainable and intelligent systems. At E&I Aluminum, we are adapting our product development and production processes to support these trends:
By adding small amounts of elements like zirconium and titanium to standard 6063 alloys, we are developing profiles with higher tensile strength and fatigue resistance. This allows structures to carry higher loads without increasing wall thickness or weight.
We are working to reduce the carbon footprint of our products by integrating recycled post-industrial scrap aluminum. Using closed-loop recycling processes, we can produce profiles that maintain mechanical properties while significantly reducing energy consumption.
We are developing digital design libraries and configuration software that integrate with standard CAD tools. This allows engineers to design, test, and analyze modular structures using E&I profile profiles, streamlining the process from design to assembly.
We provide complete design, manufacturing, and installation services to translate raw extrusions into finished, functional industrial systems.
Using 3030R round-corner profiles and standard 3030F components, we design and build machinery guards and perimeter safety fences. These systems protect operators while maintaining visibility and accessibility.
We configure specialized workbenches and assembly tables tailored to specific workflows. These structures support integrated lighting, power distribution, and tool storage, and can be easily adjusted as requirements change.
Using heavy-duty profiles like the 30120 and 30150 series, we build linear actuator guides, sensor frames, conveyor supports, and automated storage rack structures that withstand continuous dynamic loads.
