Chengdu E&I Aluminum Industry Co., Ltd., in line with the business philosophy of "people-oriented, quality value, technological innovation, and win-win cooperation", is dedicated to the research and development and manufacturing of aluminum alloy products with high difficulty, high precision and high requirements.
The company relies on The National Institute of Nonferrous Metals, drawing upon a professional aluminum alloy technology research and development team in China's light alloy industry. We provide customers with comprehensive, overall solutions for aluminum alloy products such as structural framing profiles, castings, and forgings. Our advanced production and rigorous testing equipment guarantee consistent, premium product quality, creating value-for-money commercial leverage for global industrial partners. Today, we serve as a strong strategic partner in aluminum alloy products and services, counting Fortune 500 automotive manufacturers, leading global logistics providers, and tier-1 airlines among our long-standing, satisfied clientele.
Industrial aluminum profiles are the structural backbone of modern automation, smart factories, and green infrastructure worldwide. E&I Aluminum supports this technological shift through highly adaptable modular structural designs.
Modern assembly lines rely heavily on T-slot modular systems to construct robust robotic cells, sensor mounts, linear slides, and high-speed conveyor frames. Our ENI-8-4040F profiles are optimized to absorb vibrational loads while retaining structural precision.
For semiconductor fabrication and pharmaceutical labs, contamination control is vital. Our anodized finishes (complying with GB/T 5237.4 standards) prevent outgassing and micro-particle generation, making them ideal for heavy-duty laminar flow cabinets and ESD safe workbenches.
Weight reduction without structural compromise drives the electric vehicle (EV) and aerospace industries. Specialized framing profiles such as the E&I-10-80160H handle high mechanical tension, providing structural cages that secure battery modules during transport and stress tests.
The framing profiles industry is rapidly transforming. High structural strength, sustainability, and automated smart assemblies represent the frontier of custom industrial design.
Strive to become one of the top three companies in China's aluminum alloy industry in terms of product competitiveness, innovation ability and technical strength, provide customers with products and services of superior value, and enable the company's shareholders, employees, customers, partners and society to benefit more from it Big gains and common development.
Choosing the correct aluminum profile requires detailed structural calculation. Below is a mechanical properties reference guide comparing key profiles in our lineup under severe structural loads.
| Profile Specification | Alloy Grade | Moment of Inertia Ix (cm⁴) | Moment of Inertia Iy (cm⁴) | Tensile Strength (MPa) | Yield Strength (MPa) | Key Mechanical Applications |

To ensure the safety of electromechanical systems, engineers must calculate the bending deflection ($\delta$) using: $\delta = (F \cdot L^3) / (48 \cdot E \cdot I)$ for centrally loaded beams, where $F$ is the applied force, $L$ is the span length, $E$ is the Modulus of Elasticity ($70\text{ GPa}$ for aluminum), and $I$ is the Moment of Inertia. Our high-precision profiles are extruded with tight tolerances, allowing accurate performance simulation before physical assembly.
E&I Aluminum maintains a strong development pipeline aimed at integrating AI design models and eco-friendly alloy formulations to keep our customers ahead of competitive market dynamics.

T-slot aluminum profiles offer a modular, highly flexible alternative to welded steel. They require no welding, grinding, or painting, which reduces assembly labor costs. Additionally, structures can be quickly modified, extended, or reconfigured with standard fasteners. They are also corrosion-resistant and have a clean aesthetic finish, suitable for semiconductor and pharmaceutical cleanrooms.
We primarily utilize high-grade 6000-series alloys, specifically 6063-T5, 6063-T6, and 6061-T6. The 6063-T5 temper provides a great balance of mechanical strength and surface finish quality for general automation frames, while 6061-T6 is selected for high load-bearing structural applications requiring superior yield strength.
Our standard finishes include clear anodizing and sandblasted silver/black anodizing, which offer excellent wear and corrosion protection. We also offer electrophoresis, powder coating in custom RAL colors, and fluorocarbon (PVDF) spraying for aggressive outdoor environments, matching National GB high-precision guidelines.
Yes, we provide a complete one-stop solution. Our engineers assist in modeling and structural analysis using CAD files. We offer precision cutting, drilling, tapping, counterboring, and CNC milling services. We can also pre-assemble complex frame systems in our workshop to minimize installation time at your facility.
Our QC protocols monitor chemical composition, mechanical properties, dimension accuracy, and surface film thickness. Partnering with the National Institute of Nonferrous Metals, we conduct rigorous testing on each batch. Custom structural crates and protective packaging prevent scratches and deformation during transit.
