Choosing a warranty grade powder

It is important to define your project correctly to ensure the correct product is specified and the performance and warranty is able to be gained for your project.

Step 1 Identify your project

In Australia and New Zealand the building code dictates the type of products you can choose, so it is important to select your project correctly whether it be for Aluminium or Steel. 

Dulux define projects using the table below.




  • Non-Habitable projects are those that are not dwelling types. Examples can be furniture, bus shelters, signage etc.
  • Residential properties are typically easy to maintain, given their height and access.
  • High-rise projects are less sheltered from neighbouring buildings, raising their exposure and reducing their ease of maintenance.
  • Monumental projects attract the most attention and have the highest standards required to uphold the reputation expected from landmark sites

Step 2 Identify the conditions

Once you have defined your project you must also understand the environment and conditions. 
Use the following table which references AS 4312 (Atmospheric corrosivity zones in Australia) and AS3715 (Metal Finishing – Thermoset powder coatings for architectural applications) to define the conditions of your project.


Both project type and the environment (conditions) will impact on the exposure of the powder coat to elements such as UV, dirt and salt. 

Step 3 Industry Standards

To ensure products are fit for these environments Dulux recommends suitable products based on the AS3715 and AAMA testing standards. These standards provide a benchmark of product quality that are an assurance that your asset will be protected by a product fit for purpose.

Step 4 Select your product and colour

Dulux can assist to make your choice easier through the availability of colour cards, swatches, product brochures, warranty brochures as well as a dedicated specification service.
