Explore our certified modular profile catalog optimized for automation, structural integrity, and durability.
In the modern era of structural manufacturing and automation, industrial framing requires components that guarantee structural integrity, longevity, and adaptability. Chengdu E&I Aluminum Industry Co., Ltd. (herein referred to as EI), stands at the forefront of the light alloy extrusion and custom fabrication industry. Embracing the core philosophy of "people-oriented, quality value, technological innovation, and win-win cooperation," we are dedicated to the research, development, and high-precision manufacturing of specialized aluminum products tailored to strict mechanical limits.
Collaborating with The National Institute of Nonferrous Metals, one of China's most prestigious light alloy research organizations, EI implements advanced metallurgy and precision extrusion technologies. This academic and practical synergy enables us to deliver complete, optimized solutions spanning profiles, custom castings, and forgings to global enterprises, including members of the Fortune Global 500, major automotive manufacturers, and aerospace firms.
Our production facilities utilize automatic anodizing, powder spraying, and complex precision cutting processes. Designed to adhere strictly to national and international high-precision standards, EI's products offer exceptional corrosion resistance, superior oxidation barriers, and simple connection dynamics. These profiles ensure robust vibration dampening, high torque connection, and long-term durability.
Whether formulating dynamic 3-times chain linear guide rails or constructing heavy-duty machinery chassis, our manufacturing pipeline is meticulously aligned to deliver premium mechanical performance.
Industrial manufacturing demands structural modularity. Rigid welded-steel structures are increasingly replaced by flexible, high-strength T-slot tracks due to their low weight, simplified assembly, and elimination of post-weld stress-relief treatments. The global procurement landscape highlights key requirements:
Procurement departments require framing profiles that allow fast, modular modifications without structural compromise, supporting rapid layout scaling for industrial lines.
Anodized coatings (minimum 10-15μm) are required to withstand harsh chemicals, cleaners, and humidity in automation, packaging, and laboratory environments.
Global supply chains require high-grade, recyclable primary aluminum alloys (6063-T5/T6, 6061-T6) to support green building and corporate carbon offset targets.
To meet these trends, EI uses high-purity aluminum alloys optimized for structural load distribution. Our product design features standardized 6mm, 8mm, and 10mm T-slot widths, enabling seamless mechanical integration with international standard accessories such as T-nuts, angle brackets, and linear sliders.
Our engineering catalog covers multiple industrial domains. By matching profiles with specific cross-sectional parameters, EI addresses the technical challenges of modern factory automation, warehousing, and machinery design:
Modern conveyor configurations, such as 3-times chain systems, require high dimensional stability along their entire length. EI profiles utilize specialized internal cavity geometries to limit bending and twisting under high dynamic loads. This prevents wear on rollers, ensures smooth chain operation, and extends system lifespan.
Protecting factory personnel from high-speed robotic elements requires strong, durable barriers. Profiles like the ENI-8-8080 offer the necessary structural strength to absorb accidental impacts. Our standard slot-alignment ensures simple mounting of wire meshes, polycarbonate shields, and interlocks.
Vibration is a primary cause of machining errors. The heavy-duty E&I-10-9090W and E&I-8-80160 profiles are engineered for high moment of inertia values, allowing them to support heavy components like gantry linear guides and coordinate axes while dampening dynamic vibrations.

EI strives to rank among the top tier of China's aluminum alloy manufacturing sector in terms of product competitiveness, technical innovation, and engineering strength. Our mission is to supply industries with high-value structural components that deliver reliable performance over decades.
By supporting our employees and maintaining technological capabilities, we offer customers verified structural solutions. We coordinate structural engineering, material innovation, and manufacturing management to establish and maintain reliable performance standards.
"Technological innovation is the driving force that ensures our products withstand demanding industrial operating conditions. We integrate materials science with structural design to optimize performance for our partners."
Our operations are defined by four core values that guide our engineering, production, and customer support:
To serve international projects, EI maintains strict quality assurance controls and complies with regional trade and engineering directives:
Our extrusions conform to EN 755-9 (Precision Profiles) and GB/T 5237.1 high-precision classification. Each batch undergoes testing for dimension accuracy, mechanical properties, and surface coating thickness. Handheld digital measurement systems, laser interferometers, and coordinate measuring machines (CMM) confirm that critical slot dimensions remain within tolerance limits (under ±0.15mm deviations).
Long aluminum profiles are susceptible to bending or abrasion during sea and land transport. To prevent transport damage, EI wraps profiles individually in protective PE film, bundles them using high-strength cardboard tubes or composite woven sheets, and secures them in export-approved wooden crates with internal reinforcement.
We are upgrading our manufacturing lines to include low-carbon primary smelting inputs and closed-loop scrap recycling. This reduces the carbon footprint of our extruded products, supporting green building and sustainability certifications (such as LEED and BREEAM). In addition, we are refining our extrusion dies to produce ultra-lightweight profiles with high structural performance for the aerospace and electric vehicle markets.
Expert engineering answers regarding aluminum alloy characteristics, assembly calculations, and fabrication capabilities.
6063-T5 offers excellent surface finish capabilities, making it ideal for anodizing, and has complex profile geometry features. 6061-T6 offers higher tensile and yield strength (typically 290 MPa and 240 MPa respectively), making it suitable for structural frameworks, heavy load handling, and environments requiring maximum mechanical resistance.
Standard profiles carry an anodized film of 10-15μm. This hard oxide layer prevents environmental oxygen from reacting with the underlying aluminum. For marine environments, acidic battery storage facilities, or food processing areas exposed to frequent washing, EI provides custom anodizing up to 25μm (Class I specification) to prevent pitting and crevice corrosion.
Yes. EI provides comprehensive processing services. This includes precision sawing, angle cutting, vertical and horizontal drilling, slot milling, counterboring, and threading. These processes are performed prior to finishing treatments to ensure all exposed aluminum remains protected by the anodizing layer.
