Explore our selection of standard aluminum profiles engineered with high structural integrity and customized tolerance control.
Operating with a foundational corporate ethos of "people-oriented, quality value, technological innovation, and win-win cooperation," Chengdu E&I Aluminum Industry Co., Ltd. has established itself as an elite pioneer in the development, design, extrusion, and secondary processing of advanced structural aluminum alloy products.
In close collaboration with the National Institute of Nonferrous Metals—a cornerstone in light alloy engineering—our professional R&D division focuses on producing demanding, high-precision structural shapes that withstand rigorous mechanical conditions. We supply standard and custom profiles, complex castings, and high-strength forgings to leading multinational enterprises globally, including Fortune 500 automotive manufacturers, heavy mechanical system integrators, and commercial aviation giants.
From raw extrusion to automated anodizing, paint spraying, and CNC finishing, E&I provides an integrated one-stop platform for modular structural framing, automated industrial enclosures, protective line guards, customized cleanrooms, and renewable solar mount configurations.
Aligning structural stability with modular optimization across multiple sectors.
Modular profiles such as T-slot E&I-8-6060 and mechanical guardrails support precision robots, factory line assemblies, and linear actuation setups. They enable swift structural layout modifications with high static loads without structural welding.
Aluminum’s inherent strength-to-weight ratio and corrosion-resistant anodization layer (typically >12 microns) make it suitable for solar racking systems, panel support networks, and wind turbine structural framing components.
Working closely with prominent automotive suppliers, E&I develops precision profiles for vehicle frames, battery trays, and protective structural housing, helping to decrease weight and reduce energy consumption.
E&I aluminum extrusion profiles conform to key global standards (EN-755, ASTM-B221, and GB/T 5237-2008).
