Surface Finishing for Aluminium...
Powder coating is widely used within the building industry and is by far the dominant surface finish used today. Powder coated aluminium will give your project a durable, resilient colour finish. Because the application process is free of solvents and other chemicals it is safe for the work environment as well as the natural environment.
Powder coating combines the use of chromate to protect the aluminium with a protective layer and a polyester powder to protect the chromate layer in turn and provide an attractive and durable surface finish.
Powder coating is available in a wide range of colours with commercially available surface integrity warranties from 10 to 30 years.
To determine which formulations best suite your project please refer to the NZ3604:2011 Corrosion Wind Zone map and match with the Interpon D Warranty Matrix.
Altus uses a range of colour products and finishes designed by AkzoNobel to suit most situations. AkzoNobel’s Interpon D architectural powder coatings range includes:
- Interpon D1000
- Interpon D1010 Premium Residential
- Interpon D1010 Premium Commercial
- Interpon D2015 Ultriva™
- Interpon D3020 Fluoromax®
Altus also uses Orica’s Dulux Duralloy® and Duratec® architectural powder coatings in some instances.
Altus products are applied to a minimum 50 micron thickness with a typical thickness range of 50 to 90 microns. The advantages of this are:
- Uniformity of colour.
- Good corrosion resistance (including sun degradation) and chemical resistance.
- Excellent mechanical properties and good edge cover.
- Minor surface damage can be readily touched up with colour matched dab sticks or aerosols.

Precautions and Limitations
The effects of ultra violet light, atmospheric pollution, dirt, grime, and airborne salt deposits can accumulate over time. Accumulated debris should be removed from our products at regular intervals.
Strong bold colours such as reds, yellows, and oranges are more prone to fading and colour degradation as these colours are often made with organic pigments.
Note: When judging colour consistency and integrity of finish the accepted industry standard is inspection from a distance of two metres.
