Aluminum Composite Panel Price Guide: Cost per m² Explained
Every ACP enquiry comes back with a number per square metre, and that number is almost never comparable between suppliers. Two quotes for “4 mm aluminum composite panel” can differ by 100% and both can be honest — because a bare price per m² hides the five variables that actually decide what you are buying. This guide breaks down what drives the price, so you can compare quotes on the same basis instead of on the headline figure.
1. Why a single price per m² means little
Aluminum composite panel is not one product. It is a family of products built from the same sandwich idea — two coated aluminum skins bonded to a core — at dozens of different specifications. A 3 mm panel with a 0.12 mm skin and a polyethylene core and a 4 mm panel with a 0.5 mm skin and a mineral core are both “ACP”, and they are not the same material at all. When a supplier quotes a very low number, the first question is not “how did you get it so cheap” but “what specification is that for”.
2. The five variables that set the price
- Aluminum skin thickness — the single largest cost driver, because aluminum is the most expensive input in the panel. Skins run from ultra-thin economy gauges up to 0.5 mm for facade work, and a small change in skin thickness moves the price more than most buyers expect.
- Core material — a polyethylene (PE) core is the economical baseline. A flame-retardant (FR) core costs more, and an A2 mineral-filled core costs more again, because the mineral filler and the processing to bind it are both more expensive than PE.
- Coating system — plain polyester is the cheapest and is fine indoors; a high-performance polyester is mid-range; PVDF (fluorocarbon) is the most expensive and is what exterior facades should specify. See the coating comparison below.
- Panel thickness and sheet size — 4 mm is the facade standard, with 3, 5 and 6 mm available. Standard 1220 × 2440 mm sheets price best; wider or bespoke sizes carry more waste and more setup.
- Quantity and colour — stock colours in full-container volume price lowest. A custom colour adds a minimum run per colour, because the coating line has to be set up and cleaned for it.
3. Coating: the difference between a 5-year and a 20-year facade
Coating is where cheap panels fail first, and it is the easiest place for a quote to be quietly downgraded. The three systems you will be offered are:
- Polyester (PE) — economical, good for interior use, signage and short-life applications.
- High-performance polyester — a step up in resin quality and film thickness, for mid-range exterior work.
- PVDF / fluorocarbon — the exterior-facade standard, formulated for roughly 20 years of colour and gloss retention. A genuine PVDF coating is built on a resin such as PPG with a high fluorocarbon content, not a paint that merely carries the PVDF name.
Ask which resin brand and what film thickness the coating is — a supplier who cannot name the coating supplier is quoting an unknown finish.
4. Core: PE, FR or A2
The core decides fire performance, and therefore code compliance, and it is priced accordingly. A standard PE core is combustible. An FR core resists ignition but is still a combustible polymer. An A2 panel replaces the polymer with a mineral filler so the panel contributes very little fuel to a fire — which is why A2 is normally the grade specified for high-rise and public-building facades, and why it carries a premium. If your project is code-driven, the core is not a place to take the cheapest option.
5. How to compare quotes properly
Once the specification is matched, compare on delivered economics rather than the unit price:
- Match the specification line by line — skin thickness, core, coating, panel thickness, sheet size, colour.
- State the Incoterm — an FOB quote and a DDP quote are not the same offer; the second includes freight, duty and delivery, so a higher number can be the better deal.
- Work out landed cost per usable square metre — including waste and offcuts from the sheet size, not just the quoted price.
- Check what the price excludes — samples, test reports, packaging, and whether a custom colour carries a minimum run.
As market context, standard ACP sold in volume typically trades in the low single digits per square metre, while A2 fire-rated panels with thick skins and PVDF coating sit in a clearly higher band. Treat any quote far below the band for its specification as a specification question first.
Six questions to put in every RFQ
- What is the aluminum skin thickness, in millimetres, front and back?
- What is the core — PE, FR, or A2 mineral?
- Which coating system and which resin brand, at what film thickness?
- What is the MOQ for a stock colour, and for a custom colour?
- What is the lead time in writing, and which Incoterm is the price based on?
- Can you send a sample in my exact thickness and colour before I commit to a container?
A trader can usually answer the first and the last. A factory answers all six, because it controls the coil, the coating and the composite line.
About Jinxiang
Zhejiang Jinxiang Panel Industry Co., Ltd. has manufactured aluminium composite panel since 1998, at an 18,000 m² factory in Jinhua, Zhejiang. We run 5 automatic coil coating lines and a dedicated 2-metre-wide A2 line, so the coil, the coating and the composite panel stay under one roof — which is also why our quote can be broken down line by line against the specification. We export to more than 70 countries. MOQ is one standard container for stock colours, with a 500 sqm minimum per colour for custom colours, and lead time is 10–15 days after deposit.
Send us your specification and destination market and we will quote against it line by line. See the full aluminium composite panel range, compare it with the A2 fireproof aluminium composite panel or the PVDF coating range, or contact us for a quote, a sample kit, or a factory tour — remote or in person.
