40 Series Aluminum Extrusion Profile Manufacturers

Why 40 Series Is a Workhorse for Industrial Framing

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.

Key Specifications and Trade-offs

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.

Process Fit and Application Considerations

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.

Surface Finish and Corrosion Resistance

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.

Customization and CNC Processing

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.
