Engineered for high load-bearing capacities, complex mechanical integrations, and superior oxidation resistance.
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, leveraging a professional aluminum alloy technology research and development team at the forefront of China's light alloy industry. We provide customers with comprehensive overall solutions for aluminum alloy products such as profiles, castings, and forgings.
Our advanced production and testing equipment guarantee exceptional product quality. Through excellent professional services, we create high-value commercial solutions for customers, cementing our status as a trusted strategic partner. Our core clients include several Fortune 500 organizations, major automotive brands, and key international airlines.
Driven by manufacturing excellence and strategic customer integration, we pave the way for high-performance structural systems.
Equipped with advanced mold design, high-capacity aluminum profile extrusion presses, and automated anodizing or spraying lines. We design, construct, and deliver everything from custom T-slot framing to clean sheds, automated assembly lines, and mechanical safety guards.
Our aluminum panels and profiles feature a premium structural surface finish, high corrosion/oxidation resistance, anti-loosening and shock-proof connections, and high compatibility with standard metric and imperial hardware components.
Our goal is to remain in the top echelon of China's aluminum alloy industry for innovation and technology, empowering global strategic buyers, developers, and engineers with superior products and collaborative economic gains.
We respect our workforce as our primary asset. E&I offers dynamic growth path options and premium salaries to ensure high employee retention and deep engineering domain expertise.
Every profile design, cross-section dimension, and anodizing layer is subject to strict statistical process control to provide maximum engineering utility to our end-users.
Continuous investment in light alloy research, coordinated with management innovation, keeps our structural aluminum panels and mechanical frames ahead of the global curve.
How metallurgy, structural engineering, and carbon-neutral initiatives are transforming the aluminum extrusion panel sector.
Modern applications dictate high-load mechanical capacity without weight penalty. We are fine-tuning alloy composition elements (magnesium and silicon ratios) and optimized T5/T6 thermal precipitation hardening treatments. This process achieves superior yield strength and prevents micro-structural cracking under dynamic fatigue load profiles.
By upgrading our automated anodizing line facilities, we regulate anodic layer density up to 15-25 microns. These specialized surfaces resist harsh chemical washing in lithium-battery cleanrooms, survive offshore salt-fog conditions, and display minimal outgassing under deep-space vacuum or precision semiconductor environments.
In response to global corporate environmental mandates, E&I is integrating hydro-powered raw aluminum ingots and certified low-carbon recycled aluminum scraps. Our goal is to achieve ISO 14067 Product Carbon Footprint (PCF) certification, helping global buyers offset Scope 3 emission targets.
Our structural aluminum products are engineered to function under severe conditions across diverse sectors:
No matter the size of the project, we provide comprehensive CAD designs, structural FEA calculations, and tailored alloy selection to ensure long-term performance.
How Chengdu E&I combines advanced regional materials with vertical automation to guarantee delivery continuity and competitive pricing.
Located in the Chengdu-Sichuan region, E&I accesses abundant domestic raw mineral refining grids and hydro-powered smelting systems. This logistics network keeps basic raw material input costs stable, insulating buyers from raw ingot cost spikes.
Equipped with high-tonnage automated extrusion press lines, our process minimizes physical labor variation. Continuous laser cross-section monitoring checks dimensional tolerance deviation in real-time, preventing out-of-spec batches.
We use the direct Chengdu-Europe Railway Express networks alongside deep-water sea routes to manage global transit times. This dual shipping model secures delivery predictability even during major marine shipping crises.

Ensuring compliance, structural certifications, and reliable local support for global project sites.
All extrusion panels are fabricated to conform with international standard codes including EN 755-2, ASTM B221, and RoHS environmental directives. We verify compliance using certified mill testing reports (MTR) with chemical and mechanical test logs for every batch.
To avoid surface scratches or bending during transport, profiles are individually wrapped in protective film and packed in reinforced, IPPC-compliant fumigated wooden crates. This packaging maintains profile straightness during marine and overland transport.
For large-scale assembly line installations, E&I provides detailed 3D step-by-step assembly guides, annotated mechanical CAD files, and remote engineering video consults. This remote support reduces setup issues and speeds up field assembly.
