Anodized Coated 20R T Slot Aluminium Extrusions 6 Mtr Length

The Dexterous Aluminium Profile 20x20 Radius is a precision-engineered modular framing component designed for light-duty applications where aesthetic appeal and functional strength are equally important. Crafted from premium-grade Aluminium Alloy 6063-T6, this profile offers superior corrosion resistance, excellent machinability, and long-lasting durability, making it a popular choice in automation, prototyping, and custom display structures.

With a 20mm x 20mm radius-edged cross-section, this profile combines smooth contours with modern design, giving projects a professional finish. It weighs approximately 0.429 kg per meter (±100 grams), maintaining a lightweight yet sturdy framework suitable for smaller assemblies. The profile surface area of 297.18 mm² ensures structural stability, while the rounded edges provide a refined and ergonomic appearance—perfect for visible installations in offices, labs, and showrooms.

The slot width of 6.15 mm (±0.2 mm) is compatible with M6 T-nuts and slot-6 fasteners, enabling easy integration with other modular aluminium components. The center hole diameter of Ø4.8 mm supports M6 threading or self-tapping screws, offering strong fastening points without additional machining. The smooth slot design ensures quick assembly, easy reconfiguration, and compatibility with the complete range of Dexterous Aluminium accessories.

The Dexterous 20x20 Radius Profile demonstrates excellent mechanical performance with a tensile strength of 205 MPa and yield strength of 160 MPa, ensuring reliability in both static and dynamic applications. The moment of inertia values—Ix = 0.65 cm⁴ and Iy = 0.65 cm⁴—highlight its balanced stiffness across both axes, making it ideal for small but structurally demanding builds.

In static load testing, the profile achieves the following maximum safe load capacities:

• 0.3 m span: 1230 kg

• 0.5 m span: 730 kg

• 1.0 m span: 360 kg

These figures represent static conditions without applied safety factors. For practical engineering use, a safety factor between 1.5 and 2.5 is typically recommended depending on environmental and operational factors.

Anodized with a premium matte silver finish, the surface provides superior corrosion resistance, prevents oxidation, and enhances overall appearance. This finish also improves wear resistance, making it suitable for cleanroom environments, automation labs, and aesthetically oriented applications.
