Two purchase orders for the same 4040 T-slot profile can specify different metals: one buyer writes 6063-T5, another insists on 6061-T6, and the gap between the two quotes often reaches 10 to 20 percent. That difference is not paperwork. Among aluminum alloy types, the grade yo...

READ MORE40 Series Aluminum Extrusion Profile – a 40mm x 40mm square profile with T-slots, widely used for machine frames, workstations, conveyors, and automation structures. This category offers multiple variants differing in wall thickness, slot width, and hole pattern to match load and cost requirements.
The 40 mm cross-section provides a balance of stiffness and weight. It is the most common size for medium-duty automation frames, robot cells, and assembly lines. A 40 Series Aluminum Extrusion Profile supplier typically offers profiles extruded from 6063-T5 alloy, with anodized or dual-color finishes. The ecosystem of compatible connectors, fasteners, and accessories is mature, enabling rapid assembly and reconfiguration.
When selecting a 40 series profile, focus on wall thickness, slot width, and hole diameter. Thicker walls increase load capacity but add weight and cost. Slot width determines which T-nuts and bolts fit. The table below compares common variants from the Industrial Aluminum Extrusion Profiles range.
| Model | Wall Thickness (mm) | Slot Width (mm) | Hole Diameter (mm) | Typical Application |
|---|---|---|---|---|
| HS-8-4040F | 2.0 | 8.2 | 14 deep slot | Light-duty frames, enclosures |
| HS-8-4040C | 2.0 | 8.2 | 14 deep slot | Universal automation frames |
| HS-8-4040B | 2.5 | 8.2 | – | Load-bearing supports |
| HS-8-4040D | 3.2 | 8.2 | No hole | High-strength machine bases |
| HS-8-4040W | 4.5 | 8.2 | Φ6.7 | Extra-heavy-duty structures |
| HS-8-4040BA | 2.0 | 8.5 | – | Wide-slot for larger T-nuts |
For a robot cell base, select a profile with wall thickness ≥3.0 mm (e.g., HS-8-4040D or HS-8-4040W) to minimize deflection under dynamic loads. For cleanroom partitions or light-duty workstations, the economical 2.0 mm wall variant (HS-8-4040F) is sufficient. If you need to route cables through the profile, choose a variant with a central hole (e.g., HS-8-4040W with Φ6.7 hole).
Slot width compatibility is critical. Most 40 series profiles use an 8.2 mm slot, which accepts M6 or M8 T-nuts. The HS-8-4040BA has an 8.5 mm slot for wider T-nuts. Verify that your chosen connectors and fasteners match the slot geometry. The Aluminium Profile Accessories category includes compatible T-nuts, brackets, and corner connectors.
Standard finish is silver anodized (AA10-15). Dual-color profiles (e.g., HS-8-4040CA) have a black slot for aesthetic contrast. For outdoor or corrosive environments, specify anodizing thickness ≥15 μm or powder coating. The factory offers anodizing, electrophoresis, and spraying lines, as shown on the Factory Tour page.
If standard 40 series profiles do not meet your cross-section or length requirements, the manufacturer provides Custom Mold Making for non-standard shapes. After extrusion, profiles can be cut, drilled, tapped, and milled using CNC Aluminum Processing with tolerance down to 0.01 mm. Specify hole positions, thread depths, and chamfer requirements in your RFQ.
What is the difference between 40 series and 45 series profiles?
40 series has a 40 mm cross-section, while 45 series is 45 mm. 45 series offers higher load capacity but is heavier. Choose 40 series for medium-duty frames and 45 series for heavier spans. See 45 Series Aluminum Extrusion Profile.
Can 40 series profiles be used outdoors?
Yes, with proper surface treatment. Specify anodizing thickness ≥15 μm or powder coating for corrosion resistance. Standard silver anodized profiles are suitable for indoor use only.
What accessories are compatible with 40 series profiles?
Standard M6 and M8 T-nuts, corner brackets, angle connectors, and slot covers. The Aluminium Profile Connectors category lists compatible parts.
What is the maximum length available for 40 series profiles?
Standard extrusion length is 6000 mm. Custom lengths can be cut to your specification. For longer spans, consider joining profiles with splice connectors.
How do I verify the load capacity of a 40 series profile?
Request the moment of inertia (Ix, Iy) and section modulus from the supplier. Use these values in beam deflection formulas for your specific span and load. The manufacturer can provide engineering data for each model.
Do you offer custom colors or finishes?
Yes, custom anodizing colors and powder coating (RAL colors) are available. Minimum order quantities may apply. Contact the sales team with your color code.
