INEX (Independent Extrusions) is the largest extruder of aluminium in New Zealand, supplying aluminium for over 70% of New Zealand's windows and doors.

INEX has two extrusion presses (2400 tonne 8 inch press and a 1800 tonne 7 inch press), and uses the latest manufacturing processes. 

They are the only extruder in New Zealand to source aluminium billets straight from Tiwai Point smelter in Bluff.  INEX also has a commitment to sustainability, with 99.9% of all aluminium waste recycled and sent back to the smelter.
