Our top-tier customer portfolio features Fortune Global 500 enterprises, including leading automotive brands and aerospace organizations, reflecting our commitment to structural excellence and custom extrusion engineering.
In modern manufacturing and industrial engineering, structural modularity serves as the foundation for efficiency, scalability, and rapid deployment. The global market for structural aluminum frames has transitioned from permanent welded steel assemblies toward modular T-slot aluminum extrusions. The 20mm extrusion series (including 2020, 2040, 2060, and 2080 profiles) represents the primary modular framework utilized for lightweight yet structurally stable configurations.
From micro-automation enclosures to precision coordinate tables and workspace framing, the 20mm extrusion profile offers an optimized balance of low linear weight and high torsional stiffness. As factories globally transition to Industry 4.0 automation, these extrusion profiles function as the physical building blocks for robotic gantries, sensor mounts, safety enclosures, and material handling systems. Chengdu E&I Aluminum Industry Co., Ltd. addresses this transition by delivering high-precision 20mm profiles that integrate into international industrial assemblies.
Designed for light linear guides, sensor tracks, and Pick-and-Place structures. Our 20mm extrusions provide stable positioning under high-frequency movement profiles.
Featuring custom clear anodization and closed-face variations (sealed sides). These profiles prevent particulate accumulation, making them suitable for pharmaceutical lab builds.
Integrate protective polycarbonate or wire-mesh inserts into the t-slots to form sturdy, vibration-resistant machine guarding enclosures for operator protection.
At Chengdu E&I Aluminum Industry Co., Ltd., we combine technical research and development with modern production infrastructure. Our facilities house high-tonnage extrusion presses, automated anodizing cells, electrostatic powder coating lines, and multi-axis CNC machining centers. This vertically integrated manufacturing workflow allows us to offer specialized processing, including custom length cutting, precision drilling, counter-boring, tapping, and custom assembly.
Our T-slot modular profiles are manufactured to meet high-precision national standards. They feature precise dimensional control, excellent surface finishes, and high oxidation resistance. The hardware is designed for straightforward installation using standard t-nuts, brackets, and joint connectors. This guarantees reliable connection strength, anti-loosening characteristics, and vibration resistance, ensuring structural integrity over long-term operation.
To support mechanical design calculations, our engineering team provides verified physical and structural properties for the standard 20mm series profiles. These values are essential for evaluating beam deflection, structural loading capacity, and overall frame stability under static or dynamic loads.

Deflection Calculation Reference: When designing structures using 20mm profiles, deflection ($\delta$) under a point load ($F$) at the center of a simply supported span of length ($L$) should be calculated using the formula:
δ = (F * L³) / (48 * E * I)
Where E is the modulus of elasticity for aluminum ($69,000 \text{ MPa}$ or $10,000,000 \text{ psi}$) and I is the Moment of Inertia along the bending axis.
To function as an effective global supply chain partner, Chengdu E&I Aluminum Industry Co., Ltd. aligns its operations with international quality management systems and environmental directives. Our manufacturing plants operate under certifications including ISO 9001:2015 for quality management and ISO 14001:2015 for environmental control. Our extruded structural profiles comply with RoHS and REACH regulations, facilitating integration into equipment intended for EU and North American markets.
We offer localized support through engineering design consulting, CAD file availability, and structured logistics services. Our design team assists partners from project conception through structural optimization, ensuring that chosen profile dimensions, joint hardware, and alloy grades match the targeted load cases. This approach helps reduce design cycles and material costs for our global customers.
Our extrusions conform to ASTM B221, EN 755, and GB/T 5237 high-precision standards. This controls slot width tolerances, straightness deviations, and twist profiles across production batches.
We provide clear satin anodizing (class II, >10 microns), black anodizing, architectural powder coating, and specialized chemical conversion coatings for specific industrial environments.
To prevent damage during transit, we pack profiles in inter-layered protective foam, heavy-duty cardboard boxes, and reinforced wood crates suitable for ocean freight or express air cargo.
Chengdu E&I Aluminum Industry Co., Ltd. focuses on developing sustainable production processes alongside high-precision products. The global aluminum industry is shifting toward lower carbon footprints and higher material circularity. In response, our technology roadmap prioritizes two primary initiatives: Green Alloy Development and Intelligent Manufacturing.
By integrating clean post-industrial and post-consumer scrap back into our casting processes, we offer low-carbon aluminum billets that maintain structural performance. This program helps our customers lower the embodied carbon content of their final equipment assemblies.
We are deploying inline optical monitoring sensors and AI thermal tracking cameras at our extrusion die exits. This technology detects minor surface imperfections, structural deviations, or temperature variations in real-time, helping to maintain high dimensional consistency across production runs.
