What Is an Aluminium Extrusion?
Aluminium extrusion is a process where a high-pressure ram pushes a heated aluminium billet through a shaped die to form a profile. The result is a strong, lightweight material that suits almost any building application.
Strong and lightweight
High strength-to-weight ratio for frames, doors and structural components.
Corrosion resistant
Performs in Australian conditions, including coastal environments.
Versatile
Complex shapes and profiles made to suit the application.
Easy to finish
Powder coated or anodised in a wide range of colours.
Recyclable
Aluminium can be recycled repeatedly without losing its properties.
An Aluminium Extrusion Supplier That Understands Fabrication.
We don't just supply profiles. We design and fabricate our own window and door systems, including CityView and KlassicView, so we know what fabricators need from an extrusion: consistent tolerances, clean finishes and profiles that go together easily in the workshop.
Finishes and Value-Added Services.
We can supply your aluminium extrusions ready to fabricate, with a full range of value-added services under one supplier:
Powder coating and anodising
Durable, consistent finishes in a wide range of colours, applied before delivery so profiles arrive ready to fabricate.
Cutting, drilling, punching and deburring
Profiles machined to length and prepared to your specification, saving time and handling in your workshop.
Thermal breaks
Insulating barriers added to profiles to reduce heat transfer and improve the energy performance of windows and doors.
Sand casting
Cast aluminium components produced to complement your extruded profiles and complete the system.
Custom Aluminium Extrusions.
Need a profile that isn't in our range? Our Mill Sales and technical teams design custom aluminium extrusions with you, from concept to production.
Profile design
Our CAD designers turn your sketch, specification or existing section into a production-ready drawing.
Engineering input
Wall thickness, alloy and temper selection, and performance under load.
Fabrication advice
Designing for cutting, drilling, punching, crimping and assembly.
Samples before production
Off-tool samples are supplied for your approval before bulk production.
How Our Aluminium Extrusion Process Works?
Whether you're ordering from our range or developing a new profile, here's how we take your aluminium extrusions from order to delivery:
1. Design and approval
Our technical team finalises the drawing with you.

Everything fabricators, architects and builders ask us about aluminium extrusions: what the process involves, the profiles we supply, custom dies, testing and the finishes available, with full answers below.
About aluminium extrusions2
What is aluminium extrusion?
Aluminium extrusion is a manufacturing process where heated aluminium is pushed through a shaped die to create a profile with a consistent cross-section. It's used for window and door frames, architectural features and building components.
What aluminium extrusions do you supply?
We supply aluminium window frame extrusions, door frame extrusions, screen profiles, shower screen and trim profiles, and architectural profiles for fabricators, architects and builders across Australia.
Custom profiles & quality2
Can you create custom aluminium extrusions?
Yes. Our Mill Solutions and R&D teams create custom aluminium extrusions from your drawing, specification or sample, then provide off-tool samples for approval before bulk production.
Are your extrusions tested to Australian Standards?
Yes. Our aluminium extrusions are tested to Australian Standards and inspected through our QA process before distribution.
Finishes1
What finishes are available?
Powder coating and anodising, plus value-added services such as cutting, drilling, punching, deburring and thermal breaks.
