Manufacturer-backed warranties from an accredited Brisbane powder coater
A powder coating warranty is only as good as the applicator behind it. Interpon (AkzoNobel) and Dulux will only stand behind a finish when it has been pre-treated, coated and cured to their specification by an applicator they have accredited. Superior Coaters is an accredited applicator for both brands, so the powder coating we apply to your steel and metalwork can be covered by a genuine manufacturer warranty, not just a workmanship promise.
This page explains the Interpon and Dulux warranties we can offer, what they cover, the conditions that apply and how to arrange one for your project in Brisbane, the Gold Coast or anywhere in South East Queensland.
Interpon powder coating warranties
Interpon is AkzoNobel’s powder coating brand. Its warranty systems for steel and other non-aluminium metals are only available through accredited applicators. Superior Coaters is accredited for two of them.
Interpon Metaplex Commercial
A performance warranty system for commercial and industrial metal components such as infrastructure, street furniture, plant and equipment.
- Up to 15 years colour and film integrity warranty on the topcoat
- Covers colour and gloss retention, chalking, cracking and adhesion
- Warranty term depends on the powder selected and the environment
Interpon Steelplex Diamond
An anti-corrosion warranty system for steel that combines barrier and zinc-rich primers with a premium Interpon topcoat.
- Up to 10 years corrosion protection warranty
- Up to 15 years colour and film integrity warranty
- Suited to structural steel and metalwork in demanding exterior environments
Dulux powder coating warranties
Dulux Powder & Industrial Coatings warranties can only be issued by a Dulux Accredited Powder Coater, on Dulux warranty-grade powders applied to the Dulux warranty specification.
Dulux Steel Shield™
The Steel Shield warranty for powder coated steel has two parts:
- Corrosion warranty of up to 10 years, depending on the coating system and the corrosivity of the site
- Colour warranty against fading and chalking, from 10 years on Duralloy up to 25 years on premium ranges such as Fluoroset
Steel Shield applies to mild steel, bright and semi-bright steel, and black and blue steel. Talk to us early if your project uses galvanised steel, as the warranty options are different.
Dulux Alumi Shield™
For architectural aluminium, Alumi Shield combines a colour warranty with a durability (film integrity) warranty against peeling, cracking and flaking. Terms start at 10 years for Duralloy and increase with premium ranges such as Duratec and Fluoroset.

What a powder coating warranty covers
- Film integrity: the coating will not peel, crack, flake or lose adhesion
- Colour and gloss retention: fading and chalking stay within set limits
- Corrosion protection: on steel systems such as Steelplex and Steel Shield
Conditions that affect your warranty
- Location: distance from the coast and the corrosivity of the site determine the system required and the term available
- Substrate and design: steel type, sharp edges, welds and drainage all affect coating performance
- Specification: the correct pre-treatment, primer and topcoat must be nominated before coating starts
- Handling and installation: damage on site, cutting or welding after coating is not covered
- Maintenance: the finish must be cleaned regularly and records kept
How to get a warranty on your project
- Tell us about the job early. Share the substrate, location, drawings and the finish you want before fabrication where possible.
- We recommend the system. We match an Interpon or Dulux warranty system and powder range to your environment and budget.
- Specify it by name. Nominate the warranty system, colour and an accredited applicator in your specification or tender.
- We pre-treat, coat and test. Work is carried out to the manufacturer’s specification with film thickness, cure and adhesion checks recorded.
- The warranty is registered. We lodge the project with the manufacturer and you receive the warranty documentation.
Care and maintenance keeps your warranty valid
Both Interpon and Dulux require powder coated surfaces to be cleaned regularly. Salt, dirt and pollutants left on the surface shorten the life of any coating.
- Coastal and industrial sites: clean at least every 3 months
- Inland sites: clean at least every 6 months
- Use a soft cloth or brush with mild detergent, then rinse with fresh water
- Avoid solvents, abrasive cleaners and high-pressure washing at close range
- Keep a simple log of cleaning dates in case of a claim
Powder coating warranty FAQs
Who provides the warranty, Superior Coaters or the manufacturer?
The warranty is backed by the powder manufacturer, Interpon (AkzoNobel) or Dulux. It is arranged through Superior Coaters as the accredited applicator, because the manufacturer needs our application records to register and support it.
Can any powder coater offer an Interpon or Dulux warranty?
No. Using Interpon or Dulux powder does not create a warranty on its own. The work must be done by an applicator accredited by that manufacturer, to the warranty specification. Read more about what accreditation means for your warranty.
How long does a powder coating warranty last?
It depends on the system. The warranties we offer provide up to 10 years corrosion protection on steel and from 10 up to 25 years on colour and film integrity, subject to the powder range, substrate and environment.
Should I choose Interpon or Dulux?
Both are leading Australian-supported brands. The right choice usually comes down to the colour and finish you need, the substrate and where the project is located. We can recommend the most suitable system for your job.
Does every job come with a manufacturer warranty?
No. A warranty needs to be requested and specified before coating, and the job must suit a warranty system. If you need one, tell us when you request your quote.
Do you offer warranties on large structural items?
Yes. Our oven takes items up to 14 metres long, so beams, poles and large fabrications can be coated in one piece to a warranty specification. See our industrial powder coating services.
