40x40 T Slot / V slot Extrusion

Silver satin anodised


We proudly make this extrusion in New Zealand.

We initially developed this extrusion for our own use in our plants and machinery. Its a solid little section at about 1.5KG per metre, and has surprised us by how robust it is.

Slot edges are chamfered to suit V slot wheels for use as linear rails.

Centre hole is designed to be threaded to M8 or M10 using a standard metric tap.

For large, or repeat / ongoing  orders, please get in touch, we can do a Mill Run for you at more competitive rates.

Mill orders can also be cut to your required lengths (up to 3.5m maximum), and supplied in mill finish, anodised multiple colours, or powdercoated to your requirements.


Unfortunately we are not setup to do custom cutting or custom lengths for smaller orders at this stage.

The good news is aluminium extrusion can be cut successfully with a standard builders drop saw or mitre saw. Make sure you have a sharp (new) fine tooth blade. Alternatively, most hardware and tool suppliers sell aluminium specific saw blades to fit standard saws.

A little light oil, CRC or kerosene can help getting a clean cut.

Our Cutting Tolerances are:

1200mm (+-1mm)

2400mm (+-1mm)

3500mm (+-1mm)


Please note cut lengths longer than 1600mm must be sent by heavy freight, not standard courier. (around $50 for NI and $60 for SI addresses) shorter cut lengths can be sent by courier at much lower rates.
