Aluminum composite panels are hot-pressed from aluminum sheets and polyethylene cores. They are lightweight and highly workable. Outdoor versions adopt PVDF fluorocarbon coating to resist UV rays and salt fog without fading. Indoor polyester panels come in diverse colors with high cost performance. They can be cut and bent freely, featuring sound insulation, heat preservation, waterproof and easy-to-clean performance. Widely used for building curtain walls, storefronts, indoor ceilings and advertising signs. Available in solid, wood grain, brushed, mirror and other finishes, with customizable sizes.
