Explore our highly specified structural aluminum extrusions, engineered for superior mechanical load distribution and seamless component modularity.
Guided by our founding philosophy of "people-oriented, quality value, technological innovation, and win-win cooperation," Chengdu E&I Aluminum Industry Co., Ltd. stands at the forefront of the light metals sector. We specialize in the metallurgical design and precision manufacturing of high-difficulty, high-precision, and high-spec aluminum alloy products.
By partnering with The National Institute of Nonferrous Metals, we integrate China's top academic minds in light alloy research directly with our manufacturing facilities. This collaboration allows us to deliver optimized overall solutions spanning structural extrusions, high-durability castings, and complex forgings.
Our facility houses specialized high-tonnage extrusion presses, automated anodizing plants, and multi-axis CNC machining centers. This end-to-end control ensures that every profile exhibits exceptional flatness, strict tolerances, and pristine surface finishes. As a result, we are a trusted Tier-1 supplier to global Fortune 500 corporations across the aerospace, automotive, and automation industries.
An engineering analysis of how metallurgical accuracy and precise structural profiles drive down TCO (Total Cost of Ownership).
Utilizing high-purity aluminum alloys optimized with controlled trace elements of silicon and magnesium. Our structural profiles deliver excellent yield strength, high elastic limit, and resistance to environmental stress corrosion cracking (SCC).
Profiles like the ENI-8-8080F are modeled with optimized cross-sectional moments of inertia. This provides maximum load capacity and resistance to bending under load, while minimizing overall structural weight.
Our automated anodizing lines produce a uniform, wear-resistant, and non-conductive oxide layer. This ensures reliable resistance to chemical corrosion in harsh industrial and automotive workshop environments.

Why global procurement departments leverage our manufacturing capabilities for mission-critical engineering projects.
Located in Chengdu, China, our manufacturing plant benefits from a comprehensive raw material supply chain. We procure primary aluminum ingots directly from low-carbon smelting operations, allowing us to maintain a consistent supply of clean alloy.
Our in-house capabilities include tool & die making, hot extrusion, surface anodizing, powder coating, and secondary CNC fabrication. Integrating these processes under one roof minimizes transport delays, simplifies quality control, and helps lower the overall cost of custom profiles.
We manufacture extrusions according to GB/T 5237 (high-precision level) and EN 755 structural standards. This ensures straightness and consistent slot widths for secure fitment of accessories.
Each batch undergoes inspection using spectral analyzers, tensile testing machines, and hardness testers to verify mechanical properties before leaving the factory.
Profiles are wrapped in protective film and packed in reinforced wooden crates or steel pallets. This prevents damage during ocean freight and container shipping to global destinations.

How our customized profile assemblies integrate into modern manufacturing systems.
Modern manufacturing plants rely on modular automation frames. Our 2.5 times chain profiles and heavy-duty 4080 and 8080 structural extrusions are designed to withstand continuous dynamic loads. This makes them well-suited for conveyor systems and robotic cell frames.
Key Profiles: E&I-8-8080T, 2.5 Times ChainIn semiconductor fabrication and pharmaceutical packaging, avoiding contamination is critical. Our anodized aluminum profiles feature smooth, easy-to-clean surfaces. They can be quickly assembled into structural frameworks for clean sheds, avoiding the dust and particulate generation associated with welding.
Key Profiles: ENI-8-4040A, E&I-8-4080MIndustrial operations need functional, ergonomic work environments. Our profiles can be integrated with sheet metal panels, lighting brackets, tool hangers, and ESD-safe surfaces. This allows for the assembly of durable custom workbenches and inspection stations.
