Explore our high-precision architectural and industrial modular aluminium frames designed to fulfill rigorous mechanical load profiles.
In the landscape of modern structural engineering, modularity governs efficiency. The designation of Aluminium Profile 38 represents a versatile envelope widely integrated into lightweight frameworks, heavy-duty guarding, and automated linear assembly lines.
Aluminium extrusions in the 30mm to 40mm bracket (with 38mm custom dimensions representing a sweet spot for high-moment applications with limited spatial parameters) provide an optimal balance between bending stiffness and cross-sectional density. Engineered primarily from 6063-T5 or 6061-T6 structural alloys, these profiles deliver high tensile yields that support heavy static load distributions while dramatically minimizing structural weight compared to welded steel counterparts.
By shifting to an anodized structural extrusion system, industrial plants reduce engineering cycles, cut out heavy welding labor, and bypass secondary surface treatments. The T-slot design allows for dynamic adjustment, simplifying retrofitting processes across all stages of production lifecycle management.
A strategic global partnership forged at the intersection of metallurgy, design engineering, and precision fabrication.
Guided by our core values of "people-oriented, quality value, technological innovation, and win-win cooperation," Chengdu E&I Aluminum Industry Co., Ltd. has established a formidable presence in the global supply of highly difficult, high-precision, and high-specification aluminium alloy solutions.
We work closely with the National Institute of Nonferrous Metals, drawing on a top-tier light alloy R&D team to deliver comprehensive solutions spanning profiles, castings, and forgings. Our processing lines are equipped with advanced testing machines to keep dimensional tolerances within strict national standards.
Our integrated facilities operate multiple precision extrusion systems, automated anodizing plants, and powder coating lines. We offer a true one-stop service—guiding your project from design and structural analysis to factory assembly and global shipping.
Why international procurement managers choose Chengdu E&I for mission-critical structural extrusions.
Located in a hub of raw mineral processing, we secure premium A00 aluminum ingots. Our direct partnership with the National Institute of Nonferrous Metals lets us customize alloy blends for higher mechanical strength and better corrosion resistance.
Our in-house die tooling division cuts lead times for custom geometries from weeks to days. We maintain strict control over extrusion speeds and cooling rates to ensure uniform grain structures and minimal internal stress.
Our automated anodizing lines apply consistent protective coatings from 10µm up to 25µm. This ensures clean, wear-resistant, and oxide-free surfaces that stand up to harsh industrial environments.
From cleanroom structures to automated production lines—delivering engineered stability for diverse industries.
Providing structural frames designed to withstand continuous vibrational stresses in aerospace manufacturing and automated automotive production zones. Our profiles keep heavy tools and robotics safely aligned.
Using special cleanroom anodized profiles (like the ENI-6-6090) that resist off-gassing and particulate accumulation. These cleanroom framing setups support medical, pharmaceutical, and semiconductor manufacturing.
Highly weather-resistant structural mounts for solar arrays and utility-scale green installations. Engineered to endure high wind loads and outdoor elements over decades of service.

We respect and invest in our employees, providing competitive careers and safe working environments to grow as a unified team.
We focus on building long-term value, producing durable profiles that reduce maintenance and improve uptime for our clients.
By continually investing in extrusion technology and custom tooling, we stay at the cutting edge of modern metallurgy.
We work closely with clients, suppliers, and partners to build reliable supply chains and drive shared success.
A structured approach to sourcing industrial extrusion profiles with minimal risk and maximum cost efficiency.
Sourcing structural components from overseas requires careful planning around technical specs, packing methods, and shipping schedules. At Chengdu E&I, we make global procurement simple and reliable:
For large-scale projects, we offer customized inventory management solutions, including safety stock allocations. This helps buyers mitigate market price fluctuations and avoid costly supply interruptions.
Key technological advancements shaping the next generation of structural profiles.
With industries focusing on sustainability, the demand for recycled and low-carbon aluminum is growing fast. We are constantly improving our processes to use secondary alloys without losing structural strength.
Modern frames are moving toward smarter, faster assembly systems. Integrated T-slot designs and pre-machined profiles let teams build out production lines with simple hand tools, cutting on-site installation times.
Harsh environments demand better surface protection. Newer electrocoat and hard-anodizing methods provide excellent resistance against chemicals, salt spray, and physical wear.
Technical answers to common questions about our structural profiles and production capabilities.
We manufacture our profiles to meet high-precision GB/T 5237 standard requirements. Typically, our dimensional tolerances are kept within ±0.1mm to ±0.2mm, and we can achieve tighter tolerances on critical fitment points for custom orders.
For structural frames carrying heavy loads, we recommend using 6061-T6 or 6063-T6 alloys. These tempers offer excellent mechanical strength and tensile properties, ensuring long-term structural stability.
We perform full inspections at every stage—from chemical testing of raw aluminum ingots to dimensional checks post-extrusion and coating thickness tests. Every shipment includes a quality certification report.
Normally, designing, cutting, and testing a custom extrusion die takes about 10 to 15 days. Once the sample profile is approved, volume production can start immediately.
Yes, we can pre-assemble frame structures, workbenches, and protective enclosures in our factory. We check the fitment, mark the parts for easy reassembly, and pack them securely to ensure quick installation at your site.
