JINXIANG A2 fire-rated aluminium composite panel bonds two aluminium skins to a mineral-filled, non-combustible core. Unlike a standard PE-core panel, the A2 core is built for facades where building codes restrict combustible cladding. We produce it on a dedicated 1.6-metre-wide A2 line at our 18,000 m2 factory in Jinhua, Zhejiang — wider than the 1220 mm and 1250 mm sheets most suppliers ship.
Fire performance
Fire performance of a composite panel is not a yes-or-no property — it is a position on a classification scale. In Europe, EN 13501-1 ranks reaction to fire from A1 (non-combustible) through A2 (limited combustibility), then B, C, D, E and F. A2 is the second-highest class a composite panel can realistically reach, and it is the class most facade codes are written around.
The decisive difference is what sits inside the panel. A standard ACP uses a polyethylene (PE) core. Panels sold as “FR” or “B1” use a flame-retardant PE core — they resist ignition, but they are still a combustible polymer. An A2 panel replaces that core with a mineral filler, so the panel contributes very little fuel to a fire in the first place. That is why A2 is usually the grade specified for high-rise and public-building facades.
Different markets express the same idea on different scales. Buyers exporting to the EU look for EN 13501-1 (A2-s1,d0); buyers in China look for GB 8624 (A2); buyers in the US look at ASTM E84 surface burning characteristics, and for exterior wall assemblies, NFPA 285. If your project is written against EN 13501-1, what A2-s1,d0 actually means explains how the sub-classes are decided.

Comparison
| Property | Standard PE core | FR / B1 core | A2 mineral core |
| Core material | Polyethylene | Flame-retardant polyethylene | Mineral-filled, non-combustible |
| Reaction to fire (typical) | E / F | B / C | A2 |
| Fuel contribution to a fire | High | Reduced, but still combustible | Very low |
| Where it is specified | Interior cladding, ceilings, signage | Low-rise facades, shopfronts | High-rise, public and code-restricted facades |
| Panel weight | Lightest | Light | Slightly heavier |
| Fabrication | Easiest | Easy | Same routing, folding and grooving; slightly more tool wear |
| Relative cost | Lowest | Mid | Highest |
The classification column shows typical industry values and is given for guidance only. The applicable grade for your project is the one on the test report issued for your market — ask us for it before you specify.

Factory
Most A2 panels on the market stop at 1220mm or 1250mm. Our A2 line runs up to 1600mm wide, which means fewer vertical joints across a facade, less sealant, and a faster install on large elevations. If your drawing calls for wide panels, this is the line that makes it possible.
Our five automated aluminium-coating lines run PVDF (over 70% PPG resin) and polyester (Becker) systems, with Henkel / Chemetall pretreatment and aluminium substrate from Southwest Aluminum and Ruimin Aluminum. Coating and panel are made under one roof, so the colour and gloss you approve on the sample is the colour batch you receive.
Zhejiang Jinxiang Panel Industry Co., Ltd. was established in 2010; the JINXIANG brand has been making ACP since 1998. The factory covers 18,000 m2 and ships to customers in more than 70 countries. See why buyers choose JINXIANG for the equipment, materials and quality controls behind that.
For fire-rated work you need paper, not adjectives. We issue the test documentation that applies to your destination market, along with colour samples and a physical sample kit before you commit to a bulk order. Ask for the documents for your market.
Applications
A2 fire-rated ACP is specified wherever a facade has to satisfy a fire code — typically high-rise commercial and residential towers, hospitals, schools, airports, stations, tunnels and transport interchanges.
Not sure which grade your project needs? Send us the drawing, the destination country and the building height, and we will tell you what the local code expects. See the full ACP range or read how to choose ACP for a facade project.
Ordering
Send your specification — thickness, width, colour and destination market — and we will come back with a quotation and the test documents for that market.
FAQ
No. B1 and FR describe a flame-retardant polyethylene core: it resists ignition but the core is still combustible polymer. An A2 core is mineral-filled and non-combustible, which is a different class of material and a different price bracket. A2 is generally the grade a facade code asks for once a building passes a certain height.
More than a PE-core panel and more than an FR/B1 panel, because the core material itself is more expensive. Because every project is quoted on size mix, thickness and colour, we quote per project rather than publishing a list price — send your specification and we will price it.
Yes. A2 panels are fabricated with the same routing, grooving, folding and V-grooving operations as standard ACP. The mineral core is slightly more abrasive, so tooling wears a little faster, but no new equipment is needed.
Up to 1600mm on our dedicated 1.6-metre A2 line. Wider panels mean fewer joints on the elevation.
Yes. Tell us the destination market — EU, China or US — and we will send the test documentation that applies to that market, so you can verify the claim against the certificate rather than take our word for it.
MOQ is one standard container, and custom colours have a minimum of 500 sqm per colour. Production lead time is typically 10-15 days after deposit, plus shipping.
