Dulux Powder Coatings are an ideal choice for the long term protection of mild steel items for your next project, and provide assurance through the issue of Steel Shield™ Warranties.
The Steel Shield™ warranty will only be issued on the following substrates: mild steel, bright/semi bright steel, black/blue steel. All other steel types including galvanised coated steel are not warranted under the Steel Shield™ Warranty Program.
|WARRANTY||STEEL (MILD)||BRIGHT / SEMI BRIGHT||BLACK STEEL||BLUE STEEL|
The Steel Shield™ Warranty is made up of two key components, a colour warranty (for fade and chalking) and a corrosion warranty.
|Colour Warranty||Corrosion Warranty|
Terms and conditions apply
All Dulux premium powder coat products are backed by product specific Steel Shield™ warranties. Below is an overview of the warranty periods by product available from Dulux.
*Excluding Intensity – 15 Years
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.
Both project type and the environment (conditions) will impact on the exposure of the powdercoat to elements such as UV, dirt and salt. For instance, marine and coastal environments are exposed to winds and sea salts, which have a long-term impact on the performance of coating systems due to erosion and weathering, and commercial projects will be exposed to greater environmental impacts, whether they be the usage of the environment or the height of the building.
To ensure products are fit for these environments Dulux recommends suitable products based on the 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. For complete details relating to these standards visit aamanet.org
To define projects we utilise three key sources:
1. The building classifications under the Building code of Australia (Building Classifications from the New Zealand Building Code)
2. Industry standards for powder coatings – Primarily AAMA
3. Environmental condition utilising AS4312 and ISO12944 Atmospheric corrosivity zones in Australia as a guide.
The following tables allow you to identify your project, to look at the appropriate products for the environment, whether it be interior or exterior, the care and maintenance required, and details on our Dulux Accredited Powder Coaters, as only Dulux Accredited Powder coaters are able to issue our Dulux Steel Shield™ warranties.
Project type definitions:
Use the tables below to determine the appropriate the product choice you have to gain a Steel Shield™ Warranty by determining the environment that your project will be exposed to. Use this together with the Dulux Macroclimate Corrosivity Corrosivity Zone Maps of New Zealand Guide, available here, the online Dulux SpecMap tool, available here.
1. Fluoroset may be suitable in locations <10m from the high tide line e.g. harbours (contact Dulux for advice.)
2. Electro and Duratec are only suitable for coastal environments >10m from the high tide.
3. Duralloy is only suitable for coastal environments >100m from the high tide line.
* In Mild (Medium) exterior environments a 10 year corrosion warranty is available with a Zincshield, Grey Primer/E-Prime and the indicated top coat system. Without Grey Primer/E-Prime a 5 Year corrosion warranty is available.
♦ Duratec Intensity – Steel Colour Warranty 15 Years.
Please refer to Interior and exterior environments close to liquids for warranty implications where powder coatings may be in close proximity to liquids other than the sea.
Use the following table which references AS 2312.1, SNZ TS 3404 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 Dulux Macroclimate Corrosivity Zone Maps of New Zealand Guide, available here, or Dulux SpecMap tool available here.
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:
Use the following table to help identify the product choice you have for the interior use of Dulux Premium Powder coatings on your project. Refer to the conditions information to determine the environment that your project will be exposed to.
Use the following table which references AS2312.1, SNZTS 3404 and ISO 9223 to identify the environment, conditions and atmospheric corrosivity categories
5. The corrosion rates for the first year of exposure for the different corrosivity categories of Aluminium are determined by the following standard:
Only Dulux Accredited and Dulux Prime Accredited Powder Coaters are able to issue our Dulux Steel Shield warranties after demonstrating their capability to meet stringent quality conditions and international standards.
