The product adopts a "honeycomb sandwich" structure, that is, a high-strength alloy aluminum plate coated with a weather-resistant decorative coating as a composite sheet made of a high-temperature high-pressure composite of a surface, a bottom plate and an aluminum honeycomb core.
The aluminum honeycomb board shall be made of the same material as the panel. The surface shall be anodized. The exposed side shall be coated with a protective coating. The coating material may be polyester, epoxy or acrylic. Long-term exposure to air causes corrosion of aluminum sheets.
