Why Billboard Colors Fade — And How to Make Them Last

If your signboard used to pop and now looks like it's spent too many summers in the sun, you're not imagining it.

It usually starts small. A bright red logo slowly turns pink. The blue background goes patchy. Two or three years in, a sign that cost real money looks tired — and honestly, so does the shop behind it.

Here's the part most people miss: it's rarely just the sun. It's the coating. Cheaper panels often use polyester (PE) coatings that break down under UV, and once that top layer starts to go, rain and pollution finish the job.

That's where PVDF earns its keep. Jiersun (Fujian) Decorative Building Materials Co., Ltd. manufactures aluminum composite panels, and its 3MM Aluminum Composite Panel carries a PVDF coating — a fluoropolymer finish built to hold color under long-term sun and rain, not just for the first season.

We saw this play out on a 10-year advertising signboard project in Malaysia. The client had been fighting faded, blotchy panels, and the root cause traced back to unstable local raw material quality — batch-to-batch inconsistency meant the colors never aged evenly. Moving to Jiersun's PVDF-coated 3mm panels changed that. High color stability, consistent finish, and ten years on, those signboard facades are still holding their look through tropical sun and rain.

If you're choosing panels for signage or exterior walls, a few specs actually matter:
• Coating — PVDF over PE for anything facing UV
• Thickness — 3mm is common for signboards; 4mm and 5mm where you want more rigidity
• Build — widths of 1220/1250/1500mm, alloys AA1100, AA3003, AA5005, aluminum skin from 0.05mm to 0.50mm, and a PE or fireproof core

Get those right and your signboard stops being a yearly repaint job.

What's the longest a signboard has stayed bright in your market? Curious how different climates treat them.

10 Containers of ACP Later: A Philippines Cabinet Story

A cabinet factory in the Philippines placed their first order with us more than ten years ago. Ten containers later, they still don't have a spray booth on the shop floor.

Here's what that switch actually looked like.

Before, finishing was the slowest step in their line. Cut the board, sand it, prime it, wait, sand again, spray, then wait some more before anything could be stacked or packed. That meant racks of half-finished doors sitting around, solvent smell through the whole building, overspray in the air, and a steady share of panels going back for a re-do because dust landed on a wet coat. Nobody bills for that time. It's still in every cabinet.

Aluminum composite panel shows up already finished. The coating is applied in the factory under controlled conditions, and the protective film stays on the sheet until it's cut and fitted. So the workflow becomes: measure, cut, groove or fold, install. No drying gap between steps, no booth to run, no liquid paint fumes on site. The panel is the finished surface, so the paint job stops being a separate stage of production.

For cabinet and furniture work, most shops land on 3mm, 4mm or 5mm panels, weighing roughly 3–5 kg/m². Two people can lift and position a full sheet without a hoist. Standard widths run 1220mm, 1250mm and 1500mm, and the core comes in PE or fireproof. Our full thickness range goes up to 6mm and 8mm for heavier applications.

Finishes matter more than people expect. Wood grain and marble grain panels carry a lot of the design on cabinet doors and interior fit-outs, and there's also mirror, brushed, PVDF coated, nano self-cleaning and fireproof aluminum composite panel options. Color, brand and OEM are all customizable.

Then there's the ten-year part. Same supplier, same spec, repeat orders — the panels from their early runs are still in service, still wipe clean, still sit close enough to the newer batches that nobody spots a difference along a wall. That kind of consistency across repeat orders is usually why a cabinet factory stays with one supplier instead of re-shopping the spec every season.

JIERSUN (Jiersun (Fujian) Decorative Building Materials Co., Ltd.) is an aluminum composite panel manufacturer in Fujian, China, producing since 2006. Quality control runs from incoming raw material through to the finished panel, standard orders ship in 15–20 days, and we work from a minimum of 500m². Remote technical support and free testing are part of the deal, so you can validate a finish on a sample before committing a container.

So if you run a cabinet shop and that spray booth is still eating floor space — is it cost that keeps it there, or just habit?

Cut Your Cabinet Production Costs with 5mm ACP Panels

Ten containers. Ten years. That's what a furniture manufacturer in the Philippines has been buying from us to build cabinets — and along the way, most of the painting came out of their production line.

Their old process ran on solid wood. Sanding, priming, spraying, waiting for coats to dry. Overspray, solvent smell, drying racks eating up floor space. None of that is free, and none of it gets easier when labor gets tighter.

Then they switched cabinet bodies and doors to double-sided 5MM Aluminum Composite Panel. Production costs came down. Paint-related pollution dropped significantly. And they've kept ordering for over 10 years now, which says more than any spec sheet.

What's actually inside a 5mm panel

Two aluminum coils bonded to a core with high-performance adhesive film, then finished with a PVDF or polyester coating. A protective film goes on top to prevent scratches during transport and install — it comes off at the end. The core is either PE or fireproof mineral, depending on what the project calls for.

We run these panels in widths of 1220mm, 1250mm and 1500mm, with aluminum skins from 0.05mm to 0.50mm and alloy grades AA1100, AA3003 or AA5005. Wider sheets mean fewer seams across a long cabinet run.

Why 5mm rather than 3mm

Stiffness, mostly. A 5mm panel holds a flat face better on tall doors than thinner stock does. Wood grain and marble grain finishes handle the look — you get a timber face on a cabinet without milling, sealing or repainting timber.

Maintenance is the quiet win here. No repaint cycle, no drying racks, just wipe the surface down. The panel is a passive fixed installation as well, so it draws no power to keep doing its job.

JIERSUN (Fujian) Decorative Building Materials Co., Ltd. has been manufacturing aluminum composite panels in Jinjiang, Fujian, since 2006. Panels ship in 15–20 days, the minimum order is 500 m², and dimensions, colors, textures, panel thickness, core type and coating can all be customized under OEM/ODM.

If you run a cabinet shop — is the paint line still pulling its weight, or is it the first thing you'd cut?

Which ACP Thickness Do You Actually Need? 3, 4 or 5MM

3mm, 4mm or 5mm? That's usually the first question buyers send us about aluminum composite panel — and the answer has less to do with price than with what the panel has to do every day.

Quick version, sorted by application:

3mm — the signage workhorse. Billboards, shop fronts, light boxes, exhibition panels. Light enough to cut and bend on site with normal tools, and it stays flat once it's fixed to a frame or sub-structure.

4mm — the interior pick. Wall cladding, ceilings, column wraps, retail fit-outs. That extra millimetre buys rigidity, so big surfaces don't go wavy.

5mm — what furniture factories tend to order. Cabinet doors, wardrobes, shelving, counters. More body, better screw hold, and it keeps its shape on tall panels.

What doesn't change between the three is the build. Same high-quality aluminum coils, bonded to either a PE core or a fireproof core, finished with a PVDF or polyester coating on top. Thickness is the variable — not the material underneath.

Full spec range, in case you're writing a BOQ: panel thickness 3–8mm, standard widths 1220mm, 1250mm and 1500mm, aluminum skin from 0.05mm to 0.50mm, and alloy grades AA1100, AA3003 or AA5005 (other grades on request). A protective film goes on the surface for transport and installation.

Two cases worth knowing about. A cabinet maker in the Philippines has been running our 5mm panel for over 10 years — around 10 containers so far — and says it brought their production costs down and cut the paint pollution in their workshop. Over in the Maldives, a retail signage job has been sitting outdoors for more than 10 years and the panels are still holding up.

If you're stuck between two thicknesses, don't guess and don't over-order. Tell us what you're making plus your target specs — thickness, width, aluminum skin, alloy, coating — and we'll point you at the one that actually fits.

JIERSUN has been manufacturing ACP since 2006, so this is a conversation we have most weeks.

So what's the project — a sign, a wall, or a cabinet? Drop it below and we'll tell you which thickness we'd run.

10 Years of Storefront Signage in the Maldives

Some projects you can judge in a year. This one took ten.

A retail client in the Maldives had a storefront signage problem that kept coming back. Their exterior panels started fading after only 2–3 years. Not dented, not warped — just faded. The color quietly walked off under that sun.

If you've been to the Maldives, you know the place is basically a UV stress test running year-round. Strong sunlight, salty air, and no winter to give outdoor materials a break. Anything mounted on a facade there is being tested, whether you planned for it or not.

When panels fade in a market like that, the coating system is usually the first place to look.

Standard polyester (PE) coatings are cheaper and generally do fine in gentler climates. But under constant high UV, the pigment degrades faster, the color shifts, and once it's gone there's no polishing it back — the panel has to come down. PVDF coating behaves differently. It's a fluoropolymer-based finish, and color retention under intense sun is exactly what it's built for. Grand View Research put PVDF-coated panels at the largest revenue share of the global ACP market in 2025, at 36.5%.

For this Maldives storefront, we recommended moving to PVDF-coated panels rather than the conventional boards. The client ordered 2 containers of 3mm aluminum composite panels.

That was over 10 years ago. The panels are still in service, and the fading problem that started the whole conversation is resolved. Color stability held up the way the client needed it to.

Why 3mm? For signage it's a practical middle ground — rigid enough for large fascia panels, still easy to fabricate and install. One thing worth noting though: "3mm panel" only tells you the total thickness. It says nothing about the aluminum skin underneath. On our panels, aluminum thickness ranges from 0.05mm to 0.50mm, and the skin is what carries the coating. Always ask for that number separately.

Three questions for anyone specifying ACP for signage in a coastal or high-UV market:
– What coating system is actually on the panel, PVDF or PE?
– What's the aluminum skin thickness, not just the overall panel thickness?
– Did the supplier ask about your climate before recommending a spec?

We're JIERSUN (Fujian) Decorative Building Materials Co., Ltd., an aluminum composite panel manufacturer based in Jinjiang City, Fujian, China. Our panels come in 3mm, 4mm, 5mm, 6mm and 8mm, widths of 1220mm, 1250mm and 1500mm, with PVDF, mirror, wood grain, marble grain and brushed finishes.

Honestly, the interesting part of this project isn't that it worked. It's that it took ten years to find out.

If you've specified panels somewhere with brutal sun, how long did your color actually last? Ten years still feels rare to me. ☀️

Custom ACP Is More Than Picking a Color

“Just send us the color code and we’ll match it.”

That’s a common reply when you ask about aluminum composite panels. But if you need a custom finish for a building facade, signage, or your own ACP brand, the real work starts after the color is approved. Will the coating stay consistent? Will the thickness match across the whole order? Will the next container look the same as the first?

Many buyers open with a standard catalog, then realize they need something more specific: a PVDF coating for harsh sun, a wood-grain surface for interiors, or a custom width for a signage project. An ACP panel is not just a colored sheet. It’s a composite of aluminum skins and a core—and every layer can be adapted.

In a true OEM/ODM setup, customization can include:
- Panel thickness: 3mm, 4mm, 5mm, 6mm or 8mm
- Width: 1220mm, 1250mm or 1500mm
- Aluminum skin thickness: 0.05mm to 0.50mm
- Core: PE core or fire-resistant core
- Coating/surface: PVDF, mirror, wood grain, marble grain, brushed, nano self-cleaning and more
- Brand/OEM label

JIERSUN, an aluminum composite panel manufacturer in Fujian, China, works at this level of customization. Their OEM/ODM service covers dimensions, color, texture, panel thickness, core material, coating systems, and surface finishes. But a spec sheet is only useful if the factory can repeat it. JIERSUN applies inspections from incoming aluminum coils, coatings, and core materials through the whole production process.

Why does that matter in the real world? One client in Malaysia—a local ACP manufacturer—could not maintain stable quality because of raw material, power, and production limits. For advertising signboard facades, they turned to JIERSUN for panels. The complaints dropped, and they could serve demanding customers with more confidence.

When you’re evaluating a custom ACP supplier, don’t just ask for one perfect sample. Ask how the factory controls consistency across every batch. At JIERSUN, you can start with an MOQ of 500m² and a typical lead time of 15–20 days, with remote technical support and pre-shipment inspection reports available.

What matters most to you when choosing a custom ACP supplier: sample perfection, price, or batch-to-batch consistency?

Before You Approve That ACP Quote, Check These 3 Specs

You’ve compared a few quotes for aluminum composite panels. They all say “4mm.” So why is one supplier charging more?

Sometimes the difference is hidden in the specs you didn’t compare. If you’re specifying ACP for a storefront, signboard, or building facade, here are three details that can change both performance and price:

1. The coating
What’s on the surface decides how the panel handles sun and weather. PVDF-coated aluminum composite panels are made for outdoor exposure. In a storefront project in the Maldives, panels faded after 2–3 years of strong sun. Switching to PVDF-coated ACP fixed that problem.

2. The core
Behind the aluminum skins sits the core. A standard PE core is one option, but for building exteriors, fire-rated cores are increasingly required. In Europe, facades often need ACP with an EN 13501-1 classification of A2 or B. In the US, wall assemblies may need to pass NFPA 285 or meet ASTM E84. If your project needs that level of safety, the core is not optional.

3. The aluminum thickness
Two panels can both be 4mm total, but the aluminum skin can range from 0.05mm to 0.50mm. That difference affects flatness, stiffness, and how the panel handles wind pressure and impact. It also affects the price.

Now, why does this matter? Comparing ACP by price alone doesn’t work. You need to know what coating you’re getting, what core is inside, and how strong the aluminum skin is.

At JIERSUN, we supply aluminum composite panels in a range of configurations — PVDF coated, mirror, wood grain, marble grain, brushed, nano self-cleaning, and fire-resistant options — with panel thickness from 3mm to 8mm and aluminum thickness from 0.05mm to 0.50mm. We also support custom colors, sizes, cores, and OEM/ODM orders.

Before you approve that quote, ask your supplier those three questions. It could save you from fading, warping, or compliance issues later.

Which of these three specs do you usually check first — coating, core, or aluminum thickness? Tell us in the comments.

Aluminum Composite Panel 101: What You're Actually Specifying

If aluminum composite panels keep appearing on your material list, you're not alone. They are used in building curtain walls and exterior wall decoration, commercial storefronts, signage and advertising billboards, interior decoration, and even furniture factories.

What is an ACP exactly?

At its simplest, it's a panel made of two high-quality aluminum coils bonded to a core — usually polyethylene or a fire-resistant mineral core. The outer surface is protected by a PVDF or polyester coating, and a protective film is applied to prevent scratches during transport and installation.

The basics are easy to customize. JIERSUN (Fujian) Decorative Building Materials Co., Ltd. produces aluminum composite panels in 3mm, 4mm, and 5mm thicknesses (up to 8mm), with standard widths of 1220mm, 1250mm, and 1500mm. The aluminum layer can be as thin as 0.05mm or as thick as 0.50mm. Finish options include PVDF coated, mirror, wood grain, marble grain, brushed, nano self-cleaning, and fireproof panels.

What does that mean for a buyer?

The finish and core determine where the panel can be used. A PVDF coated panel is designed for outdoor exposure, where weather and UV resistance matter. A fireproof core is available when fire performance is part of the building spec. And for decorative projects, wood grain, marble, mirror, and brushed finishes offer different visual directions while maintaining construction efficiency.

The same aluminum composite panel family can be used for an exterior curtain wall, a retail storefront, a signage board, or a furniture component. That's why 'aluminum composite panel' is a broad term — it covers a range of constructions with different cores, coatings, and textures.

Specifying ACP is not about memorizing every option. It's about matching the finish, thickness, and core to the project conditions.

JIERSUN has been manufacturing aluminum composite panels since 2006. The factory covers 20,000 m², produces around 4,000,000 m² per year, and is located 70 km from the port for easier logistics.

So the next time you see 'ACP' on a drawing, you'll know what the material actually is. What finish are you most likely to specify — wood grain, marble, mirror, or PVDF coated?

Don't Judge an ACP Factory by Its First Container

Don't Judge an ACP Factory by Its First Container

The first order always goes smoothly. Samples match. Dimensions check out. Delivery arrives on schedule.

But ask any distributor who has been buying aluminum composite panels for years, and they'll tell you the same thing: order #2 is where the real relationship begins. That's when you find out whether the first shipment was a one-time effort or a sign of how the factory actually operates.

If you're sourcing ACP for a commercial storefront, a signage program, or a building facade, you're not just buying panels. You're trusting a factory to reproduce the same color, the same thickness, the same coating — batch after batch, year after year.

That consistency doesn't come from luck. It comes from how the factory is set up.

1. Quality control baked into the process
A supplier that inspects raw aluminum coils before production, checks panels during lamination, and runs a final inspection before packing is far more likely to ship the same product twice. That's the kind of discipline JIERSUN follows from incoming material to finished goods.

2. Production capacity that protects your timeline
When a project phase gets delayed and your schedule compresses, can the factory still deliver? JIERSUN's monthly production capacity is 4 million square meters. Standard delivery is 15–20 days, and MOQ starts at 500 square meters. For buyers planning phased deliveries or repeat orders, that buffer matters.

3. A product range wide enough to consolidate orders
The more finishes one supplier can offer, the fewer vendors you need to manage. JIERSUN covers PVDF coated, mirror, wood grain, marble grain, brushed, nano self-cleaning, and fire-resistant aluminum composite panels — with customizable colors, PE or fireproof cores, and OEM branding. One qualified factory can serve multiple projects without multiplying your supplier list.

4. Support between orders
Remote technical support and free testing services make a real difference when your installation team has questions about cutting, bending, or material selection.

The best buyers don't just compare unit prices. They evaluate which factory can still serve them well three years from now.

If you're building a long-term supply relationship, JIERSUN is worth a conversation.

What's your top priority in a long-term ACP partner — price stability, consistent quality, or reliable lead times?

How to Match Aluminum Composite Panel Specs to Your Project

Choosing an aluminum composite panel (ACP) is about more than picking a color. The right specs depend on where and how the panel will be used—and getting that wrong can lead to fading and long-term performance issues.

Take a simple example. A storefront near the coast has to deal with strong UV, salt air, and rain. An interior partition in an office faces none of those. So why would you specify the same panel for both?

For exterior projects, the coating matters most. PVDF coated aluminum composite panels are widely used on facades and signage because they hold up well against UV and weather. One retailer in the Maldives learned this the hard way: their previous panels started fading after just 2–3 years. After switching to PVDF coated ACP, the fading issue was resolved and the facade kept its color for the long term.

For projects that also require fire resistance, the core material is key. You can choose between a PE core and a fireproof core, depending on your local building requirements.

Then there are the physical specs. JIERSUN panels are available in thicknesses from 3mm to 8mm, widths of 1220mm, 1250mm, or 1500mm, and aluminum thickness from 0.05mm to 0.50mm. You can select aluminum alloy grades like AA1100, AA3003, or AA5005. That means the panel can be matched to the structure, not the other way around.

Other finishes—mirror, wood grain, marble grain, or brushed—are available to match the design intent.

So how do you choose? Start with three questions: What is the environment? What are the local fire safety requirements? What kind of aesthetic do you need? Once those are clear, the material selection becomes much easier.

If you're evaluating suppliers, it also helps to know whether they can deliver at the scale your project needs. JIERSUN is a manufacturer with a 20,000 m² facility and an annual output of 4 million m². Our location 70 km from the port means shorter shipping times for international buyers. We also support OEM/ODM orders with a minimum quantity of 500 m².

What project are you working on right now? Tell us about the application—facade, signage, interior, or something else—and we can help you think through the panel specs that make sense.
