The Difference Lies In Our Preparation Of The Product.

There are no shortcuts in our craft – It is what goes on underneath the topcoat that determines the quality of our work. We make sure that we suggest the best pre-treatment regime according to the environment that your product will be exposed to, to ensure a quality product. The integrity with which your metal is treated has a direct impact on the quality and durability of the final product.

Being the only accredited Powder Coaters (INTERPON) in the South West and one of only four(4) in Western Australia out of more than 120 powder coaters in Western Australia is testament to our high standard of workmanship and quality product.

Bunbury Powder Coaters is well recognized for their quality workmanship throughout Bunbury and the South West. After all we have been serving the South West for more than 30 years so we must be doing something right.

That’s the Bunbury Powder Coaters’ difference!

Accredited Powder Coaters (INTERPON)

Interpon Approved Applicators are a part of a network of coaters in Australia, who are assessed against comprehensive criteria on an ongoing basis to ensure their pre-treatment and application procedures meet our high-quality standards.

This assurance of quality application means we can offer warranties when applied by Interpon Approved Applicators.

Steelplex Accreditation

Steelplex™ Approved Applicators can provide corrosion protection warranties to a range of Interpon coating systems for application to steel substrates.

There are five levels of Steelplex™ accreditation:

  • Steelplex™ Diamond 5
  • Steelplex™ Diamond 10
  • Steelplex™ Ruby
  • Metaplex Commercial
  • Metaplex Standard

The status of the applicator determines which system they are approved to apply

Bunbury Powder Coaters are the only powder coaters with Interpon Accreditation in the South West. Being an accredited Interpon applicator, we can offer corrosion and workmanship warranties of 5 or 10 years. Our projects are all completed in accordance to Australian Standards 4505 – 2005

NB! For accreditation certification to apply the job need to be discussed beforehand and quoted accordingly.

What standards do Steelplex™ warranties meet?

Interpon products required for Steelplex™ warranties meet the American Architectural Manufacturers Association (AAMA) and Standards Australia.

AAMA Standards are the globally recognised specification, performance requirement and test procedure for organic coatings on aluminium extrusions and panels as set out by the American Architectural Manufacturers Association. The standards assist architects, owners, and contractors to specify coatings for aluminium applications that will provide and maintain a minimum level of performance.

AS3715 for ‘Metal Finishing – Thermoset powder coating for architectural applications of aluminium and aluminium alloys’. It sets out the Australian standards required for pre-treatment, application and performance of powder coatings on aluminium substrates.

What is the Building Code of Australia (BCA)?
The Building Code of Australia (BCA) provides a nationally accepted and uniform set of technical requirements for all areas of a building, from design to construction. Developed by the Australian Building Codes Board (ABCB) on behalf of the Commonwealth, State and Territory Governments, the BCA is referred to as the building regulation in all States and Territories – 2010 – these are the regulatory Australian guidelines which defines construction requirements for residential and commercial projects.

How are the warranties issued?

Only Interpon Approved Applicators are eligible to offer Steelplex™ Ruby, Diamond 5 and Diamond 10 warranties.

A project certificate outlining the project and product details will be issued to the Approved Applicator upon completion of work.

What is the difference between an Interpon Approved Applicator and non-Approved Applicator?

Our network of approved applicators is regularly assessed against comprehensive criteria and rigorous application guidelines. Applicators are quality controlled to best in class standards to ensure their pre-treatment and application procedures meet these strict guidelines.

These standards are designed to ensure the application process is adhered to in accordance with the requirements of both AkzoNobel and global industry standards, ensuring the highest level of customer satisfaction possible.
