20 Series T-Slot / V-Slot Aluminium Extrusion System

Our 20 Series is a compact 20 x 20mm New Zealand–made aluminium extrusion, the lighter sibling of the 40 Series. T-slot and V-slot compatible, it's the go-to for 3D printers, small CNC machines, enclosures, displays and lightweight framing where the 40 Series is overkill.

Made and stocked in our Wellington factory, available mill-finish or anodised, cut to any length, same-day dispatch on stocked items, shipping across New Zealand and Australia. The full series — extrusion plus matching hardware — is below.
