Explore our premium 100 series heavy-load profiles along with high-precision structural modular configurations.
When structural stability and load-bearing performance cannot be compromised, industrial operations rely on the 100 Series aluminum extrusion systems. Designed with a footprint of 100x100mm, these structural elements represent the upper tier of modular framing profiles. They are specifically engineered to replace heavy welded structural steel in environments where flexibility, weight reduction, and rapid deployment are prioritized.
The profile's structural integrity depends on the moment of inertia ($I_x, I_y$) and cross-sectional density. Profiles such as the E&I-10-100100B with a slot width of 10mm are optimized for extreme tensile and bending stresses. Under large physical loads, they restrict deflection within strict, predictable tolerances. The incorporation of a 10mm slot depth allows the use of heavy-duty M10 T-bolts and nuts, generating higher pre-tension forces that prevent slippage when subjected to severe vibration.
For applications requiring a balance between weight and loading parameters, the E&I-8-100100 profile utilizes an 8mm slot width. This design enables seamless integration with standard modular framing elements, allowing users to scale structures without changing their existing fastening kits.
Chengdu E&I Aluminum Industry Co., Ltd. operates on a business model built around people-oriented values, quality value, technological innovation, and win-win cooperation. The company focuses on the development and production of complex, high-precision aluminum alloy systems engineered to meet demanding technical specifications.
We partner with The National Institute of Nonferrous Metals, drawing on light-alloy technical research to guide our material science formulations. Through this collaboration, our technology R&D team develops custom alloy profiles, precise aluminum castings, and structural forgings designed to handle demanding industrial tasks.
Our production lines feature advanced extrusion presses and integrated automated anodizing, powder coating, and electrostatic spraying equipment. We deliver complete, turn-key industrial solutions rather than just raw components. Chengdu E&I manages every step of the process—from custom structural frame calculation to the assembly of heavy-duty workbenches, automated enclosures, machinery guards, safety partitions, conveyor lines, and cleanroom frameworks. Our solutions are used by Fortune Global 500 automotive manufacturers, aerospace developers, and automated equipment suppliers.
Our structural aluminum profiles are engineered and verified to meet rigorous global standards.
Understanding how geographical, material, and manufacturing integration translates into direct project value for global buyers.
Unlike manufacturers that outsource surface finishing, Chengdu E&I operates integrated production lines. Our facilities run from die design and raw billet casting to extrusion presses, CNC machining centers, and automated anodizing plants. This setup reduces production bottlenecks, protects structural tolerances from wear, and ensures uniform mechanical performance across different extrusion batches.
Based in Western China, our facilities leverage local hydroelectric power networks. This clean-energy source significantly reduces the carbon footprint associated with smelting and refining primary aluminum. Partnering with us helps global enterprises lower the Scope 3 emissions in their supply chain, satisfying stringent environmental and sustainability standards.
Chengdu serves as a key logistical gateway, connected to the Chengdu-Europe express rail network and direct deep-water port systems. This infrastructure enables efficient overland transport to Central Asia and Europe, as well as cost-effective marine shipping to markets in the Americas and the Asia-Pacific region, ensuring reliable project schedules.
How the 100 Series and associated profiles solve practical industrial engineering challenges.
Heavy-duty aerospace tooling structures require low structural deflection, high absolute rigidity, and non-magnetic characteristics. By replacing welded steel with the 100x100mm heavy-duty profile system, structural engineers can reduce frame weight by up to 50% while maintaining the required strength. This substitution simplifies transport and installation, prevents corrosion issues, and allows for post-assembly modifications.
High-speed pick-and-place robotics and linear gantry systems subject framing joints to severe dynamic loads. Using profiles like the ENI-8-35130 and E&I-10-50100LC, engineers can build robust vertical structural columns. These columns support high torsional forces, minimizing positioning vibrations and protecting the calibration of optical sensors.
Modern cleanroom environments demand structures that are easy to clean, exhibit low outgassing, and resist corrosive chemical washes. Our anodized profiles feature a smooth finish that prevents dust buildup. This design complies with strict air quality standards, supporting biological enclosures, laminar flow workstations, and semiconductor handling setups.

Clear, direct answers to common questions regarding structural selection, hardware compatibility, and processing limits.
Our standard production utilizes aluminum alloy 6063-T6, which offers a balanced combination of high tensile strength, structural durability, and corrosion resistance. For projects requiring enhanced mechanical performance, we can extrude profiles using alloy 6061-T6. This option increases yield strength and improves suitability for post-extrusion precision milling.
Slot width determines the size of the fastening hardware and the maximum pre-tension load at structural joints. A 10mm slot width (as in the E&I-10-100100B) accommodates M10 heavy-duty fasteners, which are ideal for large machine bases subjected to high dynamic shear forces. An 8mm slot width (as in the E&I-8-100100) is suitable for structures carrying lighter dynamic loads and integrates easily with standard 40x40 or 80x80 framing networks.
Our profiles are finished with an anodized protective layer (12μm to 20μm thick) to prevent oxidation, chemical etching, and wear. We also offer heavy electrostatic powder coating and custom PVDF finishes for frames exposed to acidic environments, marine conditions, or corrosive industrial cleaning agents.
