An in-depth analysis of metallurgical innovation, modular assembly cost efficiency, and global supply chain integration.
For modern manufacturing enterprises and procurement directors, choosing between modular aluminum profiles and traditional welded steel systems is a core strategic decision. Modern procurement demands focus on Total Cost of Ownership (TCO), speed to market, adaptability, and carbon footprint reduction. System aluminium profiles satisfy these requirements:
System aluminium profiles provide structural frameworks across several key industrial sectors:
Providing structural support frames, robot enclosures, automated conveyor supports, AGV docking ports, and high-strength machine guard systems that are modular and easy to reconfigure.
Our heavy-duty profiles act as structural framing for solar arrays, tracking supports, and battery containment enclosures, resisting environmental stresses and oxidation.
Manufactured to high-precision tolerances with smooth anodized coatings, preventing particle generation and outgassing in semiconductor cleanrooms and medical lab equipment.
The aluminum profiles provided by Chengdu E&I Aluminum Industry Co., Ltd. are produced according to the national high-precision requirements, with exquisite appearance, high finish, strong corrosion resistance and oxidation resistance, easy installation of aluminum profile accessories, anti-loosening and shock resistance, high connection strength, and good general performance.
Using 6063-T5/T6 and 6061-T6 series alloys, we optimize mechanical properties. Our partnerships with the National Institute of Nonferrous Metals allow us to adjust alloy chemistry for specific application requirements:
| Alloy Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Hardness (HB) | Primary Industrial Applications |
|---|---|---|---|---|
| 6063-T5 | ≥ 160 | ≥ 110 | ≥ 60 | Standard structures, conveyor side frames, and modular workbenches. |
| 6063-T6 | ≥ 205 | ≥ 180 | ≥ 75 | Medium load-bearing structures, safety partitions, and linear motion tracks. |
| 6061-T6 | ≥ 265 | ≥ 245 | ≥ 95 | Heavy-duty machinery bases, cranes, dynamic gantries, and structural columns. |
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.
Chengdu E&I Aluminum Industry Co., Ltd. features structural frame design, aluminum profile extrusion capabilities, and automatic anodizing and spraying production lines. We provide structural frames, workbenches, mechanical fences, solar supports, assembly lines, storage equipment, automation setups, and clean sheds. We offer a comprehensive, one-stop design and installation service to simplify procurement and engineering.
Our automated surface treatment facilities guarantee protective coatings. Our hard-anodized coatings resist wear, harsh chemical washes, and outdoor weathering. This ensures that our profiles maintain their dimensions and look professional over decades of service.
Pioneering smart profiles, advanced surface finishes, and sustainable manufacturing practices.
As carbon taxes and sustainability guidelines become more strict, E&I is shifting toward low-carbon primary aluminum billets and post-industrial recycled scrap. This target aims to lower the carbon footprint of our extruded sections by up to 50% by 2028, aligning with the environmental goals of our automotive and electronics customers.
We are researching structural aluminum frames that incorporate embedded sensor slots and continuous vibration monitors. These profiles can detect dynamic stress levels and structural sagging in automated logistics warehouses, offering real-time structural health tracking to prevent unexpected downtime.
Working alongside the National Institute of Nonferrous Metals, our metallurgical engineering team is developing new aluminum-lithium and magnesium-silicon alloy combinations. These materials aim to match the ultimate tensile strength of carbon steel while keeping the weight and thermal advantages of aluminum.
For demanding chemical and cleanroom environments, we are scaling up testing on ceramic-reinforced anodized finishes. These nano-composite surfaces provide high scratch resistance, improve dielectric strength, and resist corrosive cleaning agents.

Helping overseas engineering teams resolve cross-border compliance, standard matching, and installation challenges.
Executing engineering projects across international borders requires strict alignment with local rules, safety practices, and design metrics. Chengdu E&I Aluminum Industry Co., Ltd. guarantees global compatibility:
Technical answers to help engineering teams design and configure structural systems.
Aluminium profile systems eliminate the need for welding, sandblasting, and post-machining, reducing labor costs. They are lightweight, corrosion-resistant, and easily modified. The structural components can be quickly adjusted or repositioned, saving setup time.
We primarily use 6063-T5/T6 and 6061-T6 alloys. 6063-T5 offers excellent surface finishes and is suitable for standard frames. For high-load and structural columns, we recommend 6061-T6 profiles, such as our 100100B series, which offer higher tensile and yield strength.
Yes. Our profiles are anodized according to national high-precision standards. The anodized layer is smooth, non-porous, and resistant to outgassing, making them ideal for semiconductor manufacturing, medical device packaging, and pharmaceutical cleanroom setups.
We provide a complete, one-stop service: custom die extrusion, automatic anodizing and powder coating, precise cut-to-length machining, tapping, drilling, and pre-assembly. We also provide engineering design reviews and structural load-bearing calculations.
We supply customized structural framing systems with engineering and design support. Our services reduce installation time, ensure compliance with international quality standards, and provide lightweight, corrosion-resistant components for manufacturing, automotive, and renewable energy sectors.
