Our most common aluminum honeycomb panels are used on curtain walls and ceilings. When decorating the ceiling, we usually choose wood grain color and ordinary white. Curtain walls are usually located in two different environments, indoor and outdoor. In the interior we often choose solid light gray and wood grain colors. If it is used outdoors, in order to prevent the aluminum honeycomb panel from discoloring due to the sun and rain, we generally recommend adopting a solid color, preferably silver gray or light gray, because these two colors are the least prone to fading and discoloration.
