Security screens can lose colour or gloss over time, but genuine fading depends on the frame material, the coating system, and where the screen sits. A well-specified aluminium or steel screen with the right powder coating can hold its colour for a very long time; a poorly prepared one can bubble and discolour within a relatively short period. Standards and exposure classification, not a single lifespan number, tell you which outcome you’re likely to get.
TL;DR:
- Proper substrate preparation and correct coating standards are essential for preventing premature fade, corrosion, and delamination in security screens.
- Coastal and industrial exposures accelerate coating deterioration unless appropriate surface treatments and exposure classifications are specified upfront.
- Routine maintenance, including gentle cleaning and inspection, can significantly slow down finish damage and reveal early signs of coating failure.
- A longevity claim without specifying the coating standard and exposure classification is unreliable; always verify these details before installation.
- Custom-made screens with documented coating specifications and exposure assessments provide better durability and warranty security.

Do security screens fade, and how does it show up on different materials?
The short answer is yes, they can, but “fading” is really several different problems wearing the same name. Colour change, gloss loss, surface erosion, coating delamination, and outright corrosion are distinct failure modes, and they don’t always happen together.
Colour change is the classic sun-bleaching effect: UV breaks down pigment molecules, and the finish looks paler or duller than it did on installation day. Gloss loss is separate, a shift from a glossy sheen to a chalky, matte surface, even if the hue itself hasn’t shifted much. Erosion describes the coating physically wearing thin over years of weather exposure. Delamination is more serious: the powder coating separates from the metal underneath, often starting as bubbling or flaking. Corrosion is what happens once that protective layer has failed and moisture reaches bare metal.
Material behaviour varies:
- Powder-coated aluminium resists corrosion well because aluminium doesn’t rust, but its coating can still chalk or lose gloss under prolonged UV exposure.
- Powder-coated steel relies entirely on the coating and any galvanising underneath for protection. If that layer is compromised, rust can appear quickly, often showing up as brown staining through a “faded” patch.
- Stainless steel mesh doesn’t rely on a coating at all, which makes visible colour change far less likely, though even stainless can develop surface staining in harsh coastal air.
A screen that looks faded may actually be signalling something worse underneath. What reads as dull or discoloured patchwork can be early delamination or corrosion, which is a workmanship and substrate issue rather than simple sun exposure.
What causes security screens to discolour or lose their finish?
Four factors drive most of the colour and finish problems homeowners see, and they tend to compound each other rather than act alone.
- UV and general weathering. Sunlight breaks down the pigments and resin binders in a coating over years of exposure, which is why north-facing and unshaded screens typically show more visible change than sheltered ones. A UV-resistant paint guide for heritage restoration work explains this same pigment and binder breakdown in more detail, and the physics is identical whether you’re talking about a heritage façade or a security screen frame.
- Airborne salt and industrial pollution. Coastal air and nearby industrial activity accelerate corrosion and finish deterioration, which is why the HIA’s guidance on corrosion protection treats exposure classification as the deciding factor in what coating a property actually needs.
- Moisture retention and trapped dirt. Grime and damp sitting against a frame, particularly around hinges and fixing points, promotes delamination from the inside out.
- Poor substrate preparation. Missing primer, insufficient galvanising, or a coating applied over inadequately cleaned metal sets a screen up to fail well before its coating’s UV resistance is ever tested.
That last point matters more than most homeowners realise. A screen in a mild climate with bad substrate prep can fail faster than a well-prepared one on a beachfront.
What do the standards actually test, and what do warranties cover?
Fast fact: There’s no single Australian standard for “how long a security screen lasts”. Instead, separate standards test specific coating properties, and the exposure classification your installer assigns determines which protection level actually applies to your job.
AS 3715:2025 sets the test procedures and performance requirements for thermoset powder coatings on architectural aluminium, covering colour change, gloss retention, and erosion resistance. If your frame is aluminium, this is the standard that underpins any claim of being “fade resistant” or “colourfast.”
For steel and other metal substrates, AS 4506:2024 is the equivalent standard, specifying performance requirements for powder coatings applied to non-aluminium metals.
Underneath both sits AS 1580, a family of weathering test methods used to measure exactly how much discolouration, dirt retention, or gloss change a coated panel shows after accelerated or natural exposure.
A few practical points worth remembering:
- A “10 to 30 year lifespan” claim without a coating spec and exposure class attached is essentially a guess.
- Ask your installer which standard their coating meets, and what exposure classification (coastal, industrial, sheltered) the job was specified against.
- Keep that documentation with your installation paperwork. It’s what you’ll need if a warranty claim ever comes up.
How can you slow down fading and finish damage?
Most of what damages a coating is preventable with basic upkeep, and the routine doesn’t need to be complicated.
Cleaning: Wash frames regularly with a soft cloth, warm water, and a mild, non-abrasive detergent, then rinse thoroughly. Avoid solvents, scouring pads, or high-pressure cleaning directly on the coating, all of which can strip gloss or create fine scratches that trap dirt.
Inspection: Walk your screens once or twice a year and look for warning signs.
- Bubbling or blistering in the coating, which usually means moisture has already got underneath it.
- Flaking or peeling paint, a clear sign of delamination rather than simple sun fade.
- Rust-coloured staining, especially around welds, hinges, and fixing points.
If you spot any of those, call a professional rather than reaching for a paint roller. Repainting over active corrosion or delamination often just hides the problem temporarily while it keeps spreading underneath.
Pro Tip: Rinse frames after storms or high-pollen periods, particularly if you’re near the coast. Salt residue left to dry on a coating does more damage sitting there than it does in the air.
Seasonal checks matter too, particularly clearing leaf litter and grit from tracks and frame edges before it holds moisture against the metal over winter.
How do you pick a fade-resistant security screen?
Getting this right at quote stage saves a lot of grief later, and it comes down to asking the right questions before you sign anything.
- Ask which standard applies. Aluminium frames should reference AS 3715; steel or other metal substrates should reference AS 4506. Ask what exposure classification your property was assessed against.
- Check the substrate prep. Galvanising on steel, correct primer, and proper surface cleaning before coating are what stop premature corrosion, not the coating alone. Poor prep at the fabrication stage is a documented cause of early powder-coat failure.
- Get warranty terms in writing. Ask specifically what’s excluded, coastal exposure clauses are common, and confirm the cleaning routine required to keep the warranty valid.
- Match the finish to your exposure. Stainless steel mesh suits harsh coastal or industrial settings well, as it doesn’t rely on a coating for corrosion resistance, while a correctly specified powder-coated aluminium frame is usually a sound, lower-cost option for sheltered or suburban locations.
What Eastern Security Doors sees on the ground
Most premature fading complaints encountered by security door providers trace back to workmanship, not weather. Insufficient galvanising on a steel frame, coating applied over a poorly cleaned substrate, or a missing primer coat all set a screen up to fail years ahead of schedule, regardless of how good the paint itself is.
Homeowners should insist on documentation before installation begins, not after. That means a written coating specification, the exposure classification the job was assessed against, and confirmation that surface preparation followed the relevant standard. Some providers build custom aluminium, steel, and stainless security doors and screens with this documentation as standard practice, because a screen is only as good as what’s underneath the finish.

FAQ
Do security screens fade over time?
Yes, security screens can fade or lose gloss, but the rate depends on the coating system, the substrate, and how exposed the property is. A well-prepared, correctly coated aluminium or steel frame can hold its appearance for many years, while poor substrate prep or heavy coastal exposure speeds up visible change.
What is the lifespan of a security screen door?
There’s no single reliable figure, because lifespan depends on material, coating quality, exposure classification, and maintenance rather than age alone. Standards like AS 3715 test specific performance properties rather than guaranteeing a set number of years, so ask your installer for the coating spec and exposure rating instead of relying on a blanket lifespan claim.
What’s a cost-effective alternative to premium branded security screens?
A custom-made screen from a local specialist can offer comparable standards compliance and warranty backing without the premium of some branded systems. Pricing is typically available on request through a consultation.
How much does a fly screen door cost?
Flyscreen pricing depends on size, mesh type, and frame material, so Easterndoors doesn’t publish a flat rate. Current pricing for flyscreens is available directly through the site or during a consultation.
Why does my security screen look different in colour to a newer replacement panel?
Weathering changes gloss and hue over time, so an aged panel rarely matches a freshly coated one exactly, even from the same coating name. It’s worth comparing physical samples in daylight and confirming the coating specification rather than relying on the colour name alone.
