Specification of powder coating finishes on architectural aluminium and other metal substrates can be a complex process and following items should be considered;
Our dedicated and knowledgeable consultants can also help simplify the specification process. Save time and money by getting the right coating advice. Call us on 13 24 99.
Our research and development team has determined that a primer be applied when powder coating perforated and expanded aluminium. This will ensure;
How to specify for perforated and expanded aluminium – example only
1st coat Primer – (Dulux E-Prime™ 953 -88386) to be applied in accordance with AS 3715-2002.
2nd coat Top coat/color – (Dulux Duratec® Zeus® Dark Grey Matt 900- 51275) to meet AAMA 2604. Product must be applied by a Dulux Registered Aluminium Applicator and must offer 20 year durability warranty.

Conditions in each location can vary greatly and this will affect the performance of various finishes. So it is vital that before specifying a given powder coating, the environmental influences on the project are understood. The resistance of each powder coating to the physical and chemical extremes of these climates determines the most suitable product.
Some environments are so extreme, that the performance of any surface finish may be compromised. For severe environments, whether they are marine and/or industrial, we recommend that you contact Dulux before specifying any powder coating finish, to ensure the site meets with our service and warranty conditions.

There are many metal substrates that can be used for architectural applications and their performance is particularly influenced by the following
Powder coatings offer an attractive and durable finish, but it is essential that consideration of industry standards (AAMA and Australian Standards), together with Care & Maintenance are taken into account to ensure that the finish achieves and maintains the expected service life.
The guidelines below provide a summary of information for the most common substrates for architectural applications. For additional information on metal preparation or advice on other metal substrates, such as brass, copper or galvanised sheeting, please refer to Australian Standard 4506-2005.
Aluminium is a versatile metal commonly used for fabrication and finishing due to functionality. Powder coated aluminium has demonstrated outstanding durability in all climates and environments.
Renowned for its strength and reinforcement, steel is best prepared using a combination of chemical and/or mechanical surface preparation, a powder coating primer and a premium Dulux top coat. Please contact our Customer Service Team prior to specification or use. Colour warranties on steel will be subject to individual written approval by Dulux.
Renowned for its corrosion protection of the base metal steel, a galvanised substrate with a powder coated surface can appear to offer a great marriage of durability and corrosion resistance. However, extreme care is required in the preparation, application and installation of powder coated galvanised steel.
Steel that has been galvanised is designed to protect the base metal. The top galvanised layer is the sacrificial offering to the inevitable progression of corrosion. If the galvanised surface is powder coated, the galvanised layer underneath the powder coating may corrode overtime and so, the adhesion of the powder coating may be compromised. This is especially pertinent when the product is located in or near severe environments such as marine or industrial areas.
On occasions, some colours, whether powder, paints or furnishings may share the same colour name but be entirely different. This is especially true of other powder suppliers who use Dulux colour names for their products, but these colours rarely match. When choosing colours, remember to specify both the Dulux product code and product name.
If the colour does not appear in our standard ranges of products, Made to Order colours can be produced. However, as each specific colour needs to be formulated and individually manufactured, there are minimum quantity requirements. Please contact our dedicated consultants team for more information.
Only Dulux Registered Applicators are issued with our Durability Warranties after demonstrating their capability to meet stringent quality conditions and international standards. Each Dulux Applicator has invested heavily in their business to guarantee their performance in preparing the aluminium and applying Dulux coatings. See our full list of Dulux Registered Applicators.
For a surface coating to provide maximum performance, the metal to be coated must be properly cleaned and prepared, the powder must be applied in accordance with Dulux recommendations and the coated metal shall be thoroughly tested for quality assurance before being released for fabrication.
With over 50 years of experience, the AAMA (American Architectural Manufacturer’s Association) is regarded as the standards leader for finishes on architectural aluminium. The AAMA objective is to develop and improve quality standards, encourage research & development and set benchmarks for product performance of architectural products.
Specifying powder coatings that comply with one of the below AAMA standards removes all doubt for the fabricator and applicator. The supply chain will be aware of the standard of product demand for the project, as the standards spell out the level of both colour performance and film properties required.
The Dulux powder coating products that meet or exceed these standards are shown below:
|Coating Type||Ultra Durable Fluoropolymer||Super Durable Polyester||Super Durable Polyester||Durable Polyester|
Specify the period of coverage for both colour retention and film integrity warranty, so that a substitute product with a warranty of equivalent film integrity but less colour retention is not used as a replacement.
Only tenders based on quotes provided by a Dulux Registered Applicator would be accurate. Verify that the applicator is authorised to apply these warrantable products by requesting a copy of the Dulux Registered Applicator certificate from the applicator.
√ The most appropriate AAMA specification
√ Environmental aspect and project type
√ Product features, including performance and colour range
√ Design and installation considerations
√ Warranty terms and conditions
Ensure the specification of the chosen finish is clearly in line with the below points:
√ Specify the Dulux “Product Name and Code” to meet
√ Nominate the AAMA standard required
√ To be applied by a Dulux Registered Applicator
√ Specify the durability warranty period
“Fluoroset® Xtreme™ Coin Satin 964-7289S to meet AAMA 2605. Product must be applied by a Dulux Registered Applicator and must offer a 30 year durability warranty.”
