Leading Supplier of Aluminium Extrusions in Australia

Aluminium extrusion is  a process, whereby a high pressure ram pushes an aluminium billet through an extrusion die to produce a profile.

The Mill Sales division at Daley Aluminium work with customers to design and fabricate customised profiles.

The talented people who are part of our Mill sales division have over 120 years’ experience in the aluminium industry and are ready to guide you through the process of design and placing an order.

Mill Sales Design Process

Darley’s Mill Sales division works closely with our customers to design and manufacture customised aluminium extrusions.

The process normally starts with Darley’s in-house CAD draftsperson, working with you to design the customised extrusion and sending it over to the extrusion factory in China to be manufactured.

All customised extrusions are tested according to Australian Standards before they are distributed to any location in Australia, or held in any one of Darley’s 4 warehouse locations.
