Powder Coat Colours for Aluminium: Codes & Matching Guide. Powder Coat Colours for Aluminium in Australia come mainly from two makers, Dulux and AkzoNobel’s Interpon.
Many share names with COLORBOND® steel colours, such as Monument, Surfmist and Woodland Grey. Understanding Powder Coat Colours for Aluminium is essential for accurate matching.

Understanding Powder Coat Colours for Aluminium is essential for accurate matching. The name alone isn’t enough to match a colour. The code tells you the maker, the exact shade and the finish, so matching the code is very important.
Powder Coat Colours for Aluminium can vary widely, and selecting the right one is crucial for project success.
When browsing options, consider the range of Powder Coat Colours for Aluminium offered by various suppliers.
Buy A Length stocks aluminium extrusions in more than 150 powder coat, anodised and mill finishes. The colour filter on the homepage shows only profiles in stock in the finish you pick.
Why are there four different Monuments?
Because “Monument” is a colour name, not a product. Each paint maker formulates its own version, in its own range of finishes, and gives it its own code. Right now Buy A Length lists four:
- Monument Matt GL229A
- Monument Satin 2729067S
- Duralloy Monument Matt 9599066M
- Textura Monument GL329A (a textured finish)
Put them side by side and they won’t look identical. Gloss level changes how dark a colour reads, and a textured surface scatters light differently from a smooth one. Surfmist has four versions too, and Woodland Grey has three.
So if you’re adding a screen door next to existing windows, “Monument” isn’t enough information. You need the code.

Each version of Powder Coat Colours for Aluminium may look slightly different due to gloss levels and textures.

How to read a powder coat colour code
Most codes follow one of two patterns.
Letter prefix plus “A”, e.g. GL229A or GA236A. These are Interpon D1000 codes from AkzoNobel. The letters group the colour family: GA codes are whites and off-whites like Surfmist Matt GA236A, and GL codes are greys like Monument Matt GL229A.
Eight characters ending in a finish letter, e.g. 2721137S or 9599066M. These are Dulux codes, from ranges such as Duralloy, Electro and Precious. The last letter often signals the finish: M for matt, S for satin and G for gloss, as in Surfmist Satin 2721137S and Duralloy Charcoal Gloss 2729086G.
When a product listing names the paint system, take it seriously. Woodland Grey Matt GL205A is flagged on the site as “Must be Interpon paint”. The name matches a Dulux colour, but the finish won’t.
Different categories of Powder Coat Colours for Aluminium provide unique benefits depending on the application.

Matt, satin, gloss or textured?
Finish matters as much as colour. Here’s how the main options behave on aluminium:
For example, the durability of Powder Coat Colours for Aluminium makes them ideal for outdoor use.
- Matt: low sheen, hides minor marks, the current favourite for new homes. Monument Matt and Surfmist Matt are typical.
- Satin: a soft sheen. It’s the traditional finish for window and door joinery, and it wipes clean easily.
- Gloss: high shine. It shows every scratch and fingerprint, so it suits trims and signage more than doors that get handled every day.
- Flat: even lower sheen than matt, mostly in the premium metallic ranges.
- Textured (Textura): a fine grainy surface that hides handling marks well. It’s popular on security doors and gates.
- Pearl and metallic: finishes like Precious Silver Pearl or Electro Gold Pearl, with flakes that catch the light. They look premium, but they vary more between batches. More on that below.
What’s the difference between “Anodic” and “Anodised”?
They sound the same, but they’re different processes.
Anodic colours, such as Anodic Natural Matt GY235A or Anodic Dark Grey Matt GL213A, are powder coats designed to look like anodised aluminium. They’re applied and cured like any other powder coat.
Anodised finishes, such as Clear Anodised 15um and Bronze Anodised 15um, are an electrochemical layer grown into the aluminium surface itself. The “15um” is the thickness of that layer in microns.
If you’re matching older anodised windows, know which one you’re looking at. A scratch test on a hidden edge helps: powder coat chips, while anodising doesn’t peel.
How do you match the colour of existing aluminium?
- Look for the code first. Window and door suppliers often record it on the invoice, the original quote or a sticker on the frame. A code beats any eyeball match.
- Note the finish. Hold the existing frame up to the light. Matt, satin and gloss are easy to tell apart side by side.
- Check which brand it is. If the original job used Interpon, stay with Interpon. If it used Dulux, stay with Dulux.
- Filter by that exact colour. Pick the code from the colour drop-down on the Buy A Length homepage and the site shows only profiles in stock in that finish. If a profile doesn’t appear, it’s not in stock today. The range changes daily.
- Order the whole job at once. This matters most for pearls and metallics, where two batches of the same code can differ slightly. One order means one batch on the wall.

Popularity varies by city and by suburb. Our guides to powder coated aluminium in Brisbane and Melbourne cover local preferences.
Powder coated or mill finish?
With many options available, Powder Coat Colours for Aluminium can meet various design requirements.
Assessing your choices for Powder Coat Colours for Aluminium is essential before making a purchase.
Choose powder coated for anything visible or exposed to weather: screens, windows, doors, signage. Choose mill finish (raw, uncoated aluminium) for concealed framing, fabrication you’ll finish yourself, or work you plan to paint.
Buy A Length’s powder coating is done in Australia, and every profile can be cut to the millimetre. That avoids the main risk with coated aluminium: cutting it on site can chip the edge and leave bare metal exposed. Here’s how cut-to-length ordering works.
Frequently Asked Questions
What are the most popular powder coat colours in Australia?
COLORBOND®-named colours lead, especially Monument, Surfmist, Woodland Grey, black and Primrose. Homeowners usually match their aluminium screens and windows to the roof and gutters.
Is Dulux Monument the same as Interpon Monument?
No. They’re formulated by different makers and won’t match exactly, especially side by side. Buy A Length lists Monument Matt GL229A, Monument Satin 2729067S, Duralloy Monument Matt 9599066M and Textura Monument GL329A, so match by code, not by name.
