Kingmets Copper Honeycomb Panel is a sandwich material consisted of: two copper skin sheets laminated to an hexagonal aluminium honeycomb core by using two components PU glue. As a more economic option, we can make the bottom skin sheet by using aluminium sheet instead of copper sheet.
Copper panel has long history to be used for architectural application, like dooms, exterior walls, interior walls, ceiling etc. It’s a durable & luxury material. The surface of copper will be naturally oxidized and this brings the material a different aesthetic beauty from other construction material. While our innovation way of using aluminium honeycomb core as a substrate material to support the copper skin sheet brings the material a very outstanding strength & cost ratio.
We also make brass honeycomb panel besides copper. Brass is a copper & zinc alloy.
Panel thickness | 10mm, 15mm, 20mm, 25mm or as required thickness |
Panel width | 600mm, 800mm, 1000mm or as required width |
Panel length | 2440mm, 3000mm, 4000mm, 5800mm or customized length |
Copper skin thickness | 0.5mm, 0.7mm, 0.8mm, 1mm or as per required thickness |
Honeycomb core | Aluminium honeycomb A6*0.05 (or as required) |
Copper alloy | Pure Copper T2, or Brass Cu62 |
Copper finishes | Natural Copper, Natural Brass, Pre-aged surface or Patina surface |
| Shape | Flat panels, or pre-fabricated shapes as per shop drawing |
| Panel edge | Closed edges, open edges |
| Antique look | Excellet flatness | |
Copper is a precious metal and it is an activate metal. The surface will naturally be oxidized and keep changing. Such an aging process gives the panel an amazing "life". The color will turn to dark brown and eventually develop a copper patina | Comparing to single layer copper panel which is quite soft, copper honeycomb panel is very rigid and surface is smooth & flat. The honeycomb core panel is a high strength hexagonal structure, it adds up a lot of strength to the copper face skin sheets. | |
| Light weight | Long service life | |
Honeycomb panel is made with a hollow but rigid core, a 10mm thick honeycomb panel with 0.7mm copper skin weighs only 13.5kgs/m2, but a 4mm thick solid copper panel weighs 35.6kgs/m2. Honeycomb panel can save the weight by 60%. | Copper is durable material, the copper patina is a natural protection to the base metal, preventing it from further oxidization. It will not rust like steel does. We can expect the copper panels to last for decades but still remains in good shape. | |
| Fire retardant | Fully recyclable | |
Copper skin sheet & honeycomb core are both fire retardant material, so the honeycomb panel is fire retardant material & classified as FR A2 grade. | Both copper skin sheet & aluminium honeycomb core can be detached and recycled after it's service life. There is bearly no environmental impact to mother earth. |
