Explore our top-tier precision-extruded profiles optimized for high-load assembly frames, laboratory enclosures, cleanroom structures, and heavy machinery support.
Aligned with the business philosophy of "people-oriented, quality value, technological innovation, and win-win cooperation", Chengdu E&I Aluminum Industry Co., Ltd. is dedicated to the research, development, and manufacturing of high-difficulty, high-precision, and high-specification aluminum alloy products. We address the complex engineering challenges faced by modern industrial production.
Our operation relies on a professional Light Alloy Technology R&D team developed in close collaboration with the National Institute of Nonferrous Metals. This relationship enables us to provide comprehensive industrial solutions, ranging from structural extrusions to precision castings and custom forgings. Our advanced production and test assets secure product consistency, delivering commercial value to our strategic partners worldwide.
Understanding the metallurgical precision and processing capacities that support Chengdu E&I Aluminum Industry Co., Ltd.'s market position.
Through strategic collaboration with the National Institute of Nonferrous Metals, we manufacture custom aluminum alloy profiles, including high-purity 6063-T5/T6 and 6061-T6 grades, maintaining consistent grain structures and mechanical performance.
We run automated extrusion and anodizing lines. Our structural profiles undergo comprehensive surface treatments to guarantee reliable performance in cleanrooms, laboratories, and abrasive industrial facilities.
We offer design, custom extrusion, assembly, and testing. Our profiles integrate with international standard fasteners, reducing assembly times for machine guards, workbenches, and linear transfer modules.
Our facility in Chengdu, Sichuan, provides clear manufacturing and logistical advantages. Positioned within China's primary industrial aerospace and nonferrous metal research corridor, we utilize local raw material reserves and research networks to optimize production costs and product quality.
Key operational benefits include:
Analyzing the technological shifts toward low-carbon manufacturing, high-precision assembly, and modular structural design.
Industrial operations face increasing environmental compliance standards. The demand for low-carbon primary aluminum and post-consumer recycled alloys is growing. Chengdu E&I utilizes energy-efficient smelting and extrusion technologies, aligning with international carbon footprint standards and circular economy initiatives.
Traditional welded steel frames are increasingly being replaced by modular aluminum extrusions due to their ease of modification. Our T-slot profiles eliminate the need for welding, sandblasting, and painting, allowing engineering teams to design, expand, or adjust machine frames and assembly lines quickly.
As automated optical inspection (AOI), semiconductor packaging, and high-speed pick-and-place robots become more common, structural aluminum frames must meet tighter dimensional tolerances. We utilize multi-axis CNC machines to achieve micron-level precision on cross-sections, bore alignments, and mounting surfaces.
Modern applications, such as cleanroom assembly structures and medical equipment enclosures, require surfaces that resist corrosion and chemical wear. Our anodized coatings protect against chemical cleaning agents, preventing corrosion and ensuring compatibility with sterile, cleanroom environments.
Our modular structural profiles are engineered for stability and reliability across diverse industrial environments.
Profiles such as the E&I-8-4080 and ENI-8-1640 provide stable frameworks for high-speed conveyor systems, production workbenches, and heavy-duty robotic mounting structures.
With smooth, anodized finishes, the ENI-6-6090 and E&I-8-4040E profiles prevent particle accumulation, making them suitable for cleanroom framing, pharmaceutical enclosures, and clean air sheds.
The E&I-8-4060 series is designed to construct industrial safety barriers, perimeter fencing, and protective equipment enclosures to safeguard work environments.
We deliver customized aluminum profile systems to address complex integration and structural challenges across major manufacturing sectors.
Industrial organizations require structural solutions that offer long-term reliability and adaptability. Chengdu E&I utilizes standard structural profiles and customized alloys to address technical demands in key industrial fields:
Automotive assembly systems demand high mechanical strength and dimensional precision. Our T-slot profiles (such as the E&I-10-50100LC) are used to manufacture automated assembly frames, inspection jigs, robotic welding bases, and conveyor systems that withstand continuous structural loads without distortion.
Microelectronic production facilities require materials that resist chemical corrosion and control electrostatic discharge. We provide specialized anodized profiles (such as the ENI-8-3030 and E&I-8-4040E) to support laboratory workspaces, cleanroom conveyor units, wafer transport lines, and environmental enclosures.
Outdoor solar energy equipment must resist environmental factors like high winds and thermal cycling. Our heavy-duty industrial profiles are treated with thick anodization layers (above 20μm) to prevent corrosion, providing structural support for solar arrays in harsh climates.
Our processes are structured to meet international supply chain requirements for consistency, reliability, and regulatory compliance.
We run a certified quality management system covering every step from melt composition testing to final dimensional inspections. Standard mechanical tests include tensile testing, hardness checks, and surface roughness verification. We document our production outputs with metallurgical analysis certificates, dimensional inspection records, and surface coating measurements to verify conformity with customer specifications.
For international shipments, we protect our structural profiles with individual surface wrapping, protective spacers, and wood-framed crates to prevent damage during sea transport. We provide transparent documentation, including custom HS coding, Certificates of Origin, and chemical compliance reports (RoHS, REACH), supporting straightforward customs clearance at destination ports.

Technical guidance regarding aluminum extrusion specifications, processing capabilities, and customization options.
Alloy 6063 is the industry standard for general industrial frames (such as 4040, 3030, and 4080 series) due to its excellent surface finish, extrusion responsiveness, and balanced mechanical strength. It anodizes well and has high corrosion resistance.
For high-load applications, mechanical brackets, or heavy structural assemblies, we recommend Alloy 6061 or Alloy 6005A, which offer higher tensile and yield strength than 6063.
We produce our profiles to high-precision specifications defined in national standard GB/T 5237 (or equivalent international standards EN 755 and ASTM B221). The normal dimensional tolerance on cross-sectional geometries is maintained within ±0.15mm to ±0.30mm depending on profile size. For critical dimensions, precision CNC post-machining can achieve tolerances of ±0.02mm.
Anodizing electrochemically develops a controlled aluminum oxide layer on the metal surface. This hard coating protects against environmental corrosion, oxidation, and minor surface abrasions. Our standard anodizing thickness ranges from 10 to 15 microns. For harsh, chemical, or outdoor environments, we can increase the coating thickness to 20 microns or more.
Yes. We provide complete OEM/ODM customization services. Customers provide detailed drawings or sample parts. Our engineering department uses Finite Element Analysis (FEA) to verify the design before cutting custom extrusion dies. This workflow ensures that custom profiles meet the specified structural and functional requirements.
Modular T-slot aluminum profiles offer three main advantages:
1. Reduced Assembly Cost: Assembly uses standard fasteners, eliminating the welding, grinding, and painting required for steel structures.
2. Adaptability: Structures can be modified, expanded, or reconfigured easily as production requirements change.
3. Weight Savings: Aluminum is approximately one-third the density of steel, reducing overall structural weight while providing sufficient rigidity for most industrial framing applications.
