Aluminum composite panel, depending on the thickness of the aluminum, the acm panel pricing difference is large. For example, the thickest can be 0.30 mm, followed by 0.25–0.20–0.18–0.15–0.12–0.10–0.08–0.06 and so on. Then the acm panel pricing gap is very large. The square meter should be priced at 3 -18 USD/M 2 .
