Explore our primary selection of high-precision T-Slot aluminium profiles and custom-designed system accessories designed for heavy loads and structural stability.
The Aluminium Profile 30 R 90° (commonly designated as R30 90-degree curved corner profile) is a highly specialized structural element engineered for corner transitions, column construction, and aesthetic framing. Combining the mechanical rigidity of 6063-T5 aluminum alloy with a smooth, rounded edge profile, it is designed for environments requiring both structural resilience and ergonomic protection.
Traditional square profiles (like the standard 3030 square frame) present exposed sharp corners, which can pose safety hazards in manual assembly workstations, cleanrooms, and medical environments. The R-series profiles solve this by incorporating a radius curvature (typically R=30mm) along the 90-degree outer corner. Key benefits include:
Our manufacturing center features automated precision extrusion and inspection systems.

Industrial modular framing systems have become the backbone of modern automation, aerospace logistics, and renewable energy sectors globally. R-series profiles bridge the gap between high-strength structural engineering and premium spatial aesthetics.
Across North America and the EU, automated packaging lines and high-velocity assembly conveyor networks utilize rounded 90-degree profiles to guarantee worker safety while maintaining high load performance limits.
Integrated solar supports, customized electronics enclosures, and clean booths utilize 30 R 90° extrusions to control ambient turbulence and prevent contaminant settlement on frame edges.
With standard ISO-compliant structural dimensions, research facilities and pharmaceutical manufacturing sites rely on high-finish anodized components to prevent chemical corrosion and ensure high durability.
From advanced auto manufacturing in Europe to cleanroom pharmaceutical environments in the US, see how our customers configure the 30 R 90° profile to fit rigid regional and spatial standards.
For top-tier car factories in North America, we supply heavy-duty panels framed with 30 R 90° profiles. The outer curved profile minimizes collision damage to personnel and moving automated guided vehicles (AGVs), preserving clean sightlines and floor efficiency.
Medical cleanrooms in Western Europe demand easy-to-clean equipment housings. The R30 90° profile eliminates tight right angles that harbor bacteria, allowing quick sanitation wipes and satisfying strict chemical-resistance profiles.
Commercial exhibitions and display designers utilize our anodized profiles for modular booth construction. The elegant satin finish combined with the continuous curves provides an aesthetic appeal absent in regular industrial designs.
Our warehousing operations integrate automated packing systems to accelerate global shipment times.
Operating out of Chengdu, the geographical and logistical core of Western China, Chengdu E&I Aluminum Industry Co., Ltd. offers a robust domestic supply chain that translates to distinct cost-performance and security advantages for global buyers:
Our manufacturing team continually tracks the cutting edge of non-ferrous metallurgy and green industrial practices. Our 5-year technical vision is built upon three pillars:
Implementing low-carbon smelting procedures and increasing the ratio of recycled post-industrial scrap to lower the absolute CO₂ footprint per metric ton, catering to strict European ESG mandates.
Enhancing the standard 6063 alloy with trace additions of zirconium and titanium to improve crystal grain refinement, providing up to a 15% increase in load capacity without weight additions.
Developing fully computerized CNC drilling, milling, and precision angle cutting to deliver pre-configured 30 R 90° frame kits straight to your warehouse, minimizing manual installation labor.
We understand that global procurement entails rigorous compliance validation. Chengdu E&I ensures that all industrial outputs align strictly with localized legislative benchmarks.
All delivered profiles conform to international engineering standards, including:
To ease localized engineering hurdles, we offer comprehensive technical support:

Gain key insights into structural selection, load metrics, and customization paths for our rounded corner T-slot systems.
The 30 R 90° profile features a radius corner that redistributes stress concentration over a larger area, mitigating shear strain when subjected to torsional forces. Additionally, the rounded corner prevents impact accidents in active workzones and complies with cleanroom airflow guidelines.
Yes. The interior design of our 30 R 90° profile maintains identical slot dimensions (typically slot width 8mm or 6mm) and center core geometries. This ensures that standard bolts, nuts, and inside corner brackets designed for the 3030 series are interchangeable, allowing you to use the R-profile exclusively for outer edges.
We provide standard clear anodized surface treatment (thickness ≥ 10μm). For environments requiring zero reflective glare or chemical exposure resistance, we offer sandblasting, black anodizing, or specialized PVDF coatings that withstand frequent ethanol wipe-downs without peeling.
Upon CAD drawing approval, die preparation requires approximately 10 to 12 working days. Sample extrusion testing and quality assurance verification are executed immediately afterward, with sample shipping occurring within 15 working days from start.
