Engineered to deliver high-load structural performance, premium anodized finish, and maximum modular flexibility for automated applications.
The global manufacturing ecosystem has experienced a massive shift toward modular design, where efficiency, adaptability, and high strength-to-weight ratios are paramount. At the center of this modular revolution is the 2020 aluminum extrusion standard (20mm x 20mm profile metric series).
Originally deployed for lightweight CNC frames and simple enclosures, the 2020 standard and its macro-derivatives (such as 4040, 8080, and 9090 profiles) have evolved into foundational elements for modern industrial automation, automotive manufacturing, solar assemblies, and aerospace tooling structures.
Unlike standard hot-rolled structural steel, E&I extruded aluminum profiles provide tight geometric tolerances. By leveraging state-of-the-art tooling and dies, we ensure flatness, straightness, and slot dimensions are maintained within micrometers. This accuracy is critical for linear motion guides, robotic axes, and automated assembly systems.
How industrial enterprises leverage modular extrusions to reduce total cost of ownership (TCO) and accelerate lead times.
In modern automated assembly plants, minimizing structure weight while retaining rigidity is vital. Extruded frames like the E&I-8-5050W and E&I-8-4080GA provide high structural load capacity, enabling the quick deployment of heavy mechanical sensors, robotic arms, protective enclosures, and cleanroom cabins.
As suppliers to major automotive and airline companies worldwide, E&I offers structural components engineered for vibration damping, high tensile loads, and long fatigue life. Our customized modular frames serve as structural assembly fixtures, testing jigs, and plant logistics equipment.
For large-scale solar installations, our customized profile frames offer high resistance against atmospheric corrosion. Standardized slots allow rapid field alignment, minimizing onsite construction labor while withstanding extreme wind and snow load parameters.

Detailed performance data governing our advanced aluminum extrusion systems.
We work closely with the National Institute of Nonferrous Metals to ensure every batch of raw billet meets or exceeds international structural criteria. Our 6000-series alloy extrusions are strictly analyzed for chemical uniformity and precipitation hardening characteristics.
By subjecting profiles to artificial aging processes, we achieve a minimum hardness rating of 8-12 Webster (HW) for 6063-T5, and 15+ HW for heavy-duty 6061-T6 profiles. This prevents structural deformation when subjected to dynamic stresses, torque, and heavy equipment loads.
Standard surfaces undergo automatic electro-chemical anodizing, building an uniform oxide barrier (thickness class 10/15/20) that protects the metal substrate from corrosion in humid, acid, or industrial environments.
