What are 45-Series Aluminum Profiles?
45-series aluminum profiles are heavy-duty T-slot extrusions with a 45 mm face width and 10 mm slot width. These profiles use M8 or M10 T-nuts and bolts, providing significantly higher load capacity and rigidity than 20- or 30-series profiles. The 45-series is the standard for industrial automation frames, large CNC gantries, heavy machine tools and structural equipment frames.
Common profiles include 4545 (square), 4590 (rectangular), and 45180 (double-length rectangular). The profiles are typically extruded from 6063-T6 aluminum for maximum strength, with clear or black anodized finish. They are compatible with a wide range of industrial automation accessories and linear motion components.

Frequently Asked Questions
What is the difference between 45-series and 40-series profiles?
45-series profiles have a 45 mm face width with 10 mm slots (M8/M10 fasteners), while 40-series profiles have a 40 mm face width with 8 mm slots (M6/M8 fasteners). 45-series is stronger and used for heavier industrial applications; 40-series is more common in Europe.
Should I use 6063-T5 or 6063-T6 for a large CNC gantry?
Use 6063-T6 for heavy-duty applications like large CNC gantries, plasma tables and machine tool frames. T6 temper provides about 30% higher strength than T5. T5 is sufficient for lighter automation frames and guards.
How much weight can a 4545 profile support as a beam?
Load capacity depends on span length, support conditions and deflection limits. As a rough guide, a 4545 standard profile (700 kg/m) spanning 1 meter with center load can handle ~500 – 800 kg with acceptable deflection. For precise calculations, request section properties (moment of inertia) from your supplier.
Can 45-series profiles be used for outdoor applications?
Yes. 6063-T6 aluminum has good atmospheric corrosion resistance. For outdoor use, specify anodized finish (minimum 15 – 20 µm thickness) or powder coating for additional protection. Avoid direct contact with dissimilar metals (steel, copper) to prevent galvanic corrosion.
What is 9090 profile used for?
9090 (90×90 mm) is the largest common T-slot profile, used for ultra-heavy-duty applications: large CNC gantry beams, machine tool bases, robotic portal frames, and test equipment that requires maximum rigidity and load capacity.
