Direct access to the flagship 50 series aluminum extrusions engineered for structural rigidity, featuring variable slot structures (8mm to 10mm) and high mechanical load thresholds.
Understanding the mechanical characteristics of the 50 series is vital for mechanical engineers calculating structural deflection. Under Google E-E-A-T guidelines, we present the structural values derived from rigorous laboratory testing of our profiles:
| Profile Type | Outer Dimensions | Slot Width | Section Area | Moment of Inertia Ix | Moment of Inertia Iy | Mass Per Meter |
|---|---|---|---|---|---|---|
| E&I-8-5050L (Lightweight) | 50 x 50 mm | 8.2 mm | 6.12 cm² | 15.42 cm⁴ | 15.42 cm⁴ | 1.68 kg/m |
| E&I-8-5050W (Industrial Heavy) | 50 x 50 mm | 8.2 mm | 9.82 cm² | 25.10 cm⁴ | 25.10 cm⁴ | 2.65 kg/m |
| E&I-10-5050B (High-Strength) | 50 x 50 mm | 10.2 mm | 10.45 cm² | 27.12 cm⁴ | 27.12 cm⁴ | 2.82 kg/m |
| E&I-8-50100 (Rectangular Base) | 50 x 100 mm | 8.2 mm | 16.80 cm² | 42.50 cm⁴ | 158.40 cm⁴ | 4.53 kg/m |
| E&I-10-50100LC (Load-Bearing) | 50 x 100 mm | 10.2 mm | 18.10 cm² | 48.10 cm⁴ | 178.60 cm⁴ | 4.88 kg/m |
For custom engineering projects, the structural calculations for deflection (f) under center-point loading can be computed using the formula:
Where F is the applied load (N), L is the unsupported span length (mm), E is the Modulus of Elasticity (70,000 N/mm² for 6063 aluminum), and I is the Moment of Inertia (mm⁴). This level of technical data ensures accurate structural integrity checks before building heavy automated gantries.
The industrial manufacturing sector is experiencing a paradigm shift from heavy, welded carbon steel frames to modular, high-tensile aluminum structural systems. Several trends drive this change:
The rise of automated guided vehicles (AGVs), autonomous mobile robots (AMRs), and smart conveyors requires lightweight, rigid structures that optimize drive motor energy consumption. The 50 series provides the necessary structural rigidity and integration flexibility for sensors, brackets, and batteries.
Unlike steel processing, which generates high emissions during welding and painting, aluminum extrusions are highly recyclable. The anodization process provides surface protection without volatile organic compounds (VOCs). Transitioning to modular aluminum supports corporate carbon-neutrality initiatives.
Modern fast-track factories require frame assembly times to drop from weeks to hours. By utilizing specialized fasteners (such as T-nuts, hammer nuts, and quick connectors), assembly, disassembly, and modification can be done on-site with simple hand tools, eliminating the need for specialized welding technicians.
Chengdu E&I Aluminum Industry Co., Ltd. leverage China's mature industrial ecosystem to supply precision-engineered aluminum extrusions globally. Key advantages of our factory operations include:
Our direct access to high-grade virgin aluminum ingots allows us to tightly control alloy composition. By melting, refining, and casting billets on-site, we maintain tight control over alloying element thresholds (Mg: 0.45%–0.9%, Si: 0.2%–0.6%), which are critical to preventing structural brittleness.
We feature fully automated extrusion presses, temperature-controlled quenching systems, and advanced anodizing baths. From raw extrusion to multi-axis CNC drilling, tapping, and surface treatments, all processes are executed under a single roof to optimize cost efficiency and quality control.
Chengdu is strategically integrated into the West-China industrial development corridor, connecting our logistics to the Chengdu-Europe express rail network and deepwater river-sea shipping routes. This allows us to deliver high-volume orders to European and North American industrial hubs within optimized timelines, ensuring predictability for large automation projects.
The versatility of the 50 series aluminum profiles is demonstrated across various high-value applications:
In automobile manufacturing, the E&I-8-5050W and E&I-10-50100LC profiles are utilized to construct ergonomic workbenches and assembly line frames. The 8mm and 10mm T-slots facilitate the integration of custom pneumatic fittings, tool-hanging balancers, and display monitors, allowing rapid reconfiguration during model changeovers.
Using lightweight yet highly structural E&I-8-5050L profiles, safety engineers build modular safety enclosures and perimeter fencing. These structures are integrated with polycarbonate panels or steel mesh. The anodized surface is resistant to chemical splashes and oil exposure, ensuring long-term structural integrity.
With high corrosion resistance, anodized 50 series profiles (such as the 50100 series) are utilized for outdoor structural frames of photovoltaic arrays. The protective oxide layer (15µm thickness class) prevents oxidation in saline, humid, and industrial environments, providing reliable service life.
Procurement and quality assurance teams of multinational companies require strict technical alignment before onboarding aluminum extrusion suppliers. Our products are engineered to comply with these global audit requirements:
We supply products adhering to high-precision tolerance classes (such as EN 755-9 and GB/T 14846 standards). For automated assembly lines, twist and straightness tolerances must be kept under 0.5mm per meter. This ensures that linear guide systems mounted on our profiles operate smoothly without binding or premature wear.
Our anodizing procedures follow the ISO 7599 standard. Film thickness checks, sealing quality validation (via acid-dissolution tests), and hardness testing are performed on every production batch to verify performance in harsh environments.
For every shipment, we provide complete transparency with material test reports (MTRs) detailing chemical analysis and mechanical property compliance (yield strength, tensile strength, and elongation percentage). This ensures traceability from raw material to finished product.
Profiles are individually wrapped with protective film, packed with interlayered pearl cotton, and shipped in reinforced wooden crates or steel frames. This prevents surface scratching, bending, or damage during multi-modal ocean and overland transit.
