Copper honeycomb core panel is consisted of a natural real copper sheet as skin, an aluminium sheet as bottom, glued to aluminum honeycomb core. The copper skin sheet is an active metal, it will weather naturally and oxidized. The color will turn from bright gold color to tarnished light brown color and then dark brown color and eventually to a patina green color. Such a natural oxidization progress will take from several years up to 10 years. But we can do surface treatment on the copper and get a pre-oxidize look on our copper honeycomb core panel. That means you can order light brown color copper honeycomb panel or dark brown color copper honeycomb panel from us and no need to wait for several years.   Read More>
