How to Choose Aluminum Composite Panel for Facades
Specifying aluminum composite panel (ACP) for a facade is a decision between fire safety, coating durability, and cost. Getting it wrong means a failed fire inspection or a panel that fades within five years. This guide walks through the four decisions that matter, based on 25+ years of manufacturing ACP.
1. Fire rating: A2 or PE core?
Check your local building code first. High-rise and public buildings in most jurisdictions require a non-combustible A2-rated core (EN 13501-1 A2, NFPA 285). PE-core panels are economical and fine for interiors, signage, and low-rise applications where code allows. If you are not sure, specify A2 — it is the safe default for any exterior wall. Our A2 aluminum composite panel page lists the grades, the test reports and the certifications behind it.
2. Coating: PVDF or polyester?
For exterior panels, choose PVDF fluorocarbon coating with at least 70% resin content — it resists UV fading and chalking for 20+ years. Polyester is a budget option best suited to interiors. On Jinxiang panels, PVDF resin comes from PPG (USA) and polyester from Becker (Sweden), with German pretreatment from Henkel and Chemetall. The finish is applied to the aluminium coil before the panel is bonded, and we coat that colour coated aluminum coil in-house on 5 coil coating lines.
3. Thickness and width
Standard panels are 3–4 mm for facades and 2–3 mm for interior or signage. Widths up to 1500 mm are typical; wider panels reduce joints but need stiffer cores and better flatness. Confirm your glazing, joint, and bracket system before ordering. If you are still weighing ACP against solid aluminium or honeycomb cladding, read the three-system comparison before you fix the substructure.
4. Verify the supplier is a real factory
Many ACP sellers are traders reselling from multiple mills, which means inconsistent quality and no control over your order. Ask for: the ACP factory address, production line photos, ISO9001 certificate, test reports, and a sample kit before ordering. A factory with its own coil coating lines controls quality from substrate to finish — that is the difference between a 10-year panel and a 25-year panel. Our own aluminum composite panel factory in Jinhua coats the coil and laminates the panel under one roof.
What to request from your supplier
- ISO9001 certificate and fire test report (A2)
- PPG / coating supplier confirmation for PVDF lines
- Sample kit with the exact thickness and color you plan to buy
- Miami-Dade NOA documentation for US coastal projects, if applicable
