Our Story

Originally established in 1997 as Ashhurst Aluminium and then the company rebranded to Alumax Systems Ltd. in 2016. We are now one of Manawatu’s leading joinery suppliers.

Our company’s success comes down to hard work in supply, manufacturing and fabricate superior residential and commercial aluminium joinery. From standard assembly to complete design and build, Alumax Systems can produce any type of window or door you require.

We are a family run business.

Alumax Systems was started in the early 1980s and are a locally run family business. It has since evolved into one of the leading suppliers of aluminium joinery for the Manawatu region. The dedicated team of professionals at Alumax Systems have been involved in a number of significant projects including the rebuild of Christchurch after the 2011 earthquake.
