Commercial projects contain a large variety of projects that can range from commercial offices, a car park, a school, a sports ground, a prison, a veterinary practice or hospital. 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.

Typically commercial environments are exposed to greater environmental impacts, whether they be through the usage of the environment, the height of the building or the physical environment and weather. For these reasons Dulux recommends higher standard products for use in these conditions based on the AAMA standards. These products are designed to withstand different conditions, provide protection and offer a superior performance which will protect your asset in a variety of environments. 
To help in this process we utilise: 
  1. The building classifications under the Building code of Australia (BCA).
  2. Industry standards for powder coatings.
 
 
The following tables detail the BCA classes, building examples in those classes, and the industry standards that a product should meet to be suitable. Use this information as a guide to identifying your project and the choice of product that you have, including exterior and interior applications.

*Dulux products that meet just AAMA 2603 and AS3715 are supported for Dulux Alumi Shield™ and Steel Shield™ warranties on interior applications on commercial projects when applied by a Dulux Accredited Powder Coater to the warranty specification on recommended project types and conditions

The following table can be used to help identify the product choice you have for the exterior use of Dulux Premium Powder coatings on your commercial project.

● Alumi Shield and Steel Shield warranties are available when applied by a Dulux Accredited Powder Coater to the warranty specification on recommended project types and conditions.
All Dulux powder products are NOT suitable in strongly acidic or caustic environments so the pH must be between 5 and 9.
1. Fluoroset may be suitable in locations <10m from the high tide line e.g. harbours (contact Dulux for advice).
2. Electro, Charisma, Duratec, Armourspray and Protexture, are only suitable for environments >10m from the high tide line.
Please refer to ‘Exterior environments close to liquids other than coastal, river and lake salt water environments’ for warranty implications where powder coatings may be in close proximity to liquids.
Information for Perforated and Expanded aluminium:
Alumi Shield™ warranties on perforated and expanded aluminium in exterior environments are available for the following products and conditions:
a. Mild – Protexture, Armourspray, Duratec, Charisma, Electro and Fluoroset (E-Prime base coat not mandatory)
b. Severe – Protexture, Armourspray, Duratec, Charisma, Electro and Fluoroset (E-Prime base coat mandatory)

Conditions – Exterior

Use the following table which references AS2312.1, AS 4312 and ISO 9223 to identify the environment, conditions and atmospheric corrosivity categories
To pinpoint your projects corrosivity zone this table should be used together with the corrosivity zone maps contained within AS 4312.

1. Geothermal environments greater than 500m of a bore, mud pool, steam vent, or other source with a pH between 5 and 9. For pH outside this consult Dulux.
2. Geothermal hot spots within 500m of a bore, mud pool, steam vent, or other source.
3. All offshore islands including Waiheke Island, Stewart Island, Fraser Island and Pacific islands eg PNG, Fiji, Samoa, Tonga, Tahiti, Noumea
4. The corrosion rates for the first year of exposure for the different corrosivity categories of Aluminium and Carbon (Mild) Steel are determined by the following standards:
AS 4312 – Atmospheric corrosivity zones in Australia.
AS 2312.1- Guide to the protection of structural steel against atmospheric corrosion by the use of protective coatings. Part 1: Paint coatings
ISO 9223 – Corrosion of metals and alloys – Corrosivity of atmospheres – Classification, determination and estimation
5. The corrosion rates for the first year of exposure for the different corrosivity categories of Aluminium are determined by the following standard:
ISO 9223 – Corrosion of metals and alloys – Corrosivity of atmospheres – Classification, determination and estimation

Exterior environments close to liquids other than coastal, river and lake salt water environments

For buildings that have exterior powder coated assets close to liquids other than the sea, e.g. outdoor swimming pools, fountains, outdoor bathrooms etc., please refer to the guidance below to understand your product choice and the warranty limitations in these environments.

1. Aggressive liquids such as Chemically Treated liquids and Salt Water must be cleaned off immediately as per the Dulux Care and Maintenance guide.
Please note chemically treated water includes antimicrobial treatments, e.g. in pools, anti-corrosive chemicals, and soapy water in bathrooms and showers.
■ Where indicated Alumi Shield and Steel Shield warranties are available on areas >than 1m from the liquid.
✓ Where indicated Alumi Shield and Steel Shield warranties are available on areas >than 2m from the liquid (ie outside the splash zone).
● Where indicated Alumi Shield and Steel Shield warranties are available any distance from the liquid.
Alumi Shield and Steel Shield warranties are only available when applied by a Dulux Accredited Powder Coater to the warranty specification on recommended project types and conditions.
All Dulux powder product are NOT suitable in strongly acidic or caustic environments so the pH must be between 5 and 9.
Alumi Shield and Steel Shield warranties are not available if the powder coating is immersed in any liquid.

The following table can be used to help identify the product choice you have for the interior use of Dulux Premium Powder coatings on your commercial project.

● Alumi Shield and Steel Shield warranties are available when applied by a Dulux Accredited Powder Coater to the warranty specification on recommended project types and conditions
○ Non-warrantable
Please refer to ‘Interior environments close to liquids’ for warranty implications where powder coatings may be in close proximity to liquids.
Information for Perforated and Expanded aluminium:
Alumi Shield Warranties on perforated and expanded aluminium in interior environments are available for the following products and conditions:
a. General – Duralloy, Precious, Protexture, Armourspray, Duratec, Charisma, Electro, and Fluoroset (E-Prime base coat not mandatory).
b. Moderate – Protexture, Armourspray, Duratec, Charisma, Electro and Fluoroset (E-Prime base coat mandatory).
