4040 T-slot extrusion for rigid modular frames

The 4040 T-Slot Extrusion (40 Series) – 40mm x 40mm x 1.0m – 15mm Centre Web (Black) is a high-strength aluminum profile for robust, modular, and precision-built structures. It is designed for industrial automation, CNC machines, enclosures, and other heavy-duty frameworks where rigidity and repeatable assembly matter.

The 15mm centre web adds strength and rigidity, making the profile a practical choice for load-bearing applications and precision engineering projects that need stable structural support.

Key features and benefits of the 40 Series 4040 extrusion

• 6063-T5 aluminum construction provides a strong, lightweight profile suited to durable structural builds.
• Black anodized finish improves corrosion resistance while giving the extrusion a clean, professional look.
• T-slot profile design supports easy, flexible assembly with standard T-nuts and fasteners.
• 15mm centre web improves structural integrity and increases load-bearing capability.
• Precision machined profile helps maintain tight tolerances for smoother assembly and alignment.
• Modular 40 Series format supports expandable frame design using compatible brackets, fasteners, and panel mounts.
