40x40MM T Slot Aluminium Profile

The Dexterous Aluminium Profile 40x40 is one of the most widely used structural framing profiles for industrial, automation, and modular system applications. Manufactured from premium Aluminium Alloy 6063-T6, it combines outstanding strength, rigidity, and corrosion resistance with lightweight versatility, making it a preferred choice for engineers and fabricators worldwide.

With a cross-sectional dimension of 40mm x 40mm, this profile offers the perfect balance between compactness and stability. Weighing approximately 1.16 kg/m (±150 grams), it provides exceptional load-bearing strength without unnecessary bulk. Its surface area of 430 mm² ensures high stiffness and excellent mechanical performance across various load conditions.

The Dexterous 40x40 T-Slot Profile features a slot width of 10.2 mm (±0.2), designed for use with M12 T-nuts, bolts, and fasteners, ensuring compatibility with a broad range of aluminium profile accessories. The center hole diameter of Ø10 mm allows for M12 threading or self-tapping, enabling quick and secure connections during assembly.

Engineered for demanding environments, this profile offers a tensile strength of 205 MPa and a yield strength of 160 MPa, ensuring reliable performance under mechanical stress. Its moment of inertia (Ix = 7.9 cm⁴, Iy = 7.9 cm⁴) provides consistent resistance to bending and torsional forces, making it suitable for both vertical and horizontal load applications.

In static load testing, the profile supports up to:

• 684 kg at a 0.3 m span

• 410 kg at a 0.5 m span

• 205 kg at a 1 m span

These values are under static loading conditions without applied safety factors. For engineering design, a safety factor between 1.5 and 2.5 is recommended depending on the application.

The anodized finish gives the profile an elegant, matte silver appearance that resists corrosion, oxidation, and wear. This ensures long-lasting performance even in harsh industrial environments while maintaining a clean, professional aesthetic.

Its modular T-slot system enables quick and flexible assembly using standard Dexterous brackets, connectors, and accessories—eliminating the need for welding or painting. The reusability of the system allows easy modification or reconfiguration of structures, saving both time and material costs.
