Explore our premium grade modular aluminum profiles optimized for automation, structural assembly lines, and high-load machinery frames.
The 20 x 20 mm aluminium extrusion is a vital structural module in industrial automation, lightweight mechanical structures, and precision engineering framework fabrication. Frequently termed 2020 profile, its standardized cross-section features a central cylindrical core (ideal for tapping to M6 metric thread) connected by web supports to external T-slots or V-slots with standard 6mm slot widths.
Manufactured from architectural and structural grade 6000-series aluminum alloys—predominantly 6063-T5 or 6063-T6—this profile offers an exceptional strength-to-weight ratio. The chemical composition is carefully calibrated with silicon (0.2–0.6%) and magnesium (0.45–0.9%) to achieve precise yield strengths and excellent surface anodization quality.
"Understanding the structural deflection limits and mechanical properties of 20x20 extrusions allows engineers to construct high-rigidity structural frameworks with minimum raw material overhead."
A trusted technical partner delivering high-difficulty, high-precision, and custom extrusion components to leading global organizations.
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 in China's light alloy industry. We provide customers with overall solutions for aluminum alloy products such as profiles, castings, and forgings. Production and testing equipment guarantee product quality, and excellent professional services create value-for-money commercial value for customers, becoming a strong strategic partner for customers in aluminum alloy products and services. The main customers include the world's top 500 companies such as automobile companies and airlines, and have been widely praised by customers for many years.
Operating hot extrusion presses with capacities ranging from 600 to 5,000 metric tons, producing profiles according to national high-precision requirements, with exquisite appearance, high finish, strong corrosion resistance, and oxidation resistance.
Equipped with automatic anodizing, powder coating, and electrophoresis lines. Delivering finishes like satin anodized, electrocolored, and micro-grooved structures. T-slot structures offer easy installation of accessories, anti-loosening, and shock resistance.
Providing one-stop services for structural frameworks, industrial workbenches, protective cages, cleanroom structures, photovoltaic mounting racks, conveyor systems, and logistics optimization from raw concept to final physical assembly.
Industrial scale, logistical clusters, and state-of-the-art technological capabilities translate to optimized pricing and unmatched precision.
China-based extrusion factories feature complete upstream supply chains. Billet casting, mold tooling design, and extrusion are situated in close physical clusters, minimizing internal freight and reducing tooling fabrication lead times from weeks to mere days.
Partnering with organizations like the National Institute of Nonferrous Metals ensures rigorous quality control over mechanical parameters like grain structure, intermetallic distribution, and tempering. This guarantees structural integrity and predictability under constant stress.
Located near major multimodal transport hubs, Chinese factories offer highly developed packaging protocols (e.g., interleaving paper, heat-shrink plastics, custom steel crates) that safeguard high-finish anodized products from oxidation and physical abrasions during maritime transport.

Years of Engineering Experience
The industrial aluminum market is shifting toward micro-modular, standardized profiles to support rapid scaling in manufacturing. Key trends include:
By adapting 20 x 20 mm extrusions, manufacturers avoid welding processes, reducing heat-affected zone (HAZ) vulnerability and eliminating post-weld stress relief processes.
Discover how engineering departments integrate 20 x 20 modular profiles into localized industrial environments.
Designed with standard 6mm slots to mount sensor arrays, compressed-air manifolds, and LED task lights, providing ergonomics for assembly lines.
Ideal for 3D printers, CNC routers, and visual inspection booths. The profile slots easily accept panel materials like acrylic or polycarbonate.
The smooth, corrosion-resistant anodized finish is particulate-free and compatible with strict chemical sanitization processes.
Supports brackets, guide rails, and photoelectric sensors. Low weight reduces structural loads on floors and support beams.
