Kingmets Copper Composite Panel is a composite material made of two copper skin sheets laminated to a plastic core. We also make top skin with copper sheet and bottom side with aluminium sheet to achieve more affordable cost. The composite core is available in standard LDPE core (low density polyethylene), FR B1 core (mineral filled fire retardant B1 grade). And copper skin we can replace with brass skin sheet (a copper & zinc alloy) too.
Copper composite panel is an ideal replacement to solid copper panel for facade & interior wall cladding. Copper composite panel keeps same natural copper surface like solid copper panel, but with the sandwich structure it becomes lower cost and meanwhile panel strength and flatness is greatly better. Copper has long history to be used for architectural decoration, as it is luxury material and has long life span. Its surface will naturall oxidized to turn brown and eventually develops a green copper patina for the reason that copper is an active metal.
Panel thickness | 3mm, 4mm, 5mm, 6mm |
Panel width | 600mm, 800mm, 1000mm or as required width |
Panel length | 2440mm, 3000mm, 4000mm, 5800mm or customized length |
Copper skin thickness | 0.3mm, 0.5mm |
Composite core | LDPE core, FR B1 core, FR A2 core |
Copper alloy | Pure Copper T2, or Brass Cu62 |
Copper finishes | Natural Copper, Natural Brass, Pre-aged surface or Patina surface |
| Classic material | Smooth surface | |
Natural copper & antural brass is a high end architetural material. The natural oxidization process of is like a vivid life growing from young to old. Eventually when the green patina forms, the copper will brings the building a classic antique appearance. | The 3-layer composite panell structure is a stable and rigid form, the plastic core has added up a lot of strength to support the copper skin sheets. Thus copper composite panel can achieve a flat and smooth panel surface, unlike the single layer solid copper sheet that is soft and un-flat. | |
| Light weight | Cost saving | |
A 4mm thick copper composite panel weighs at around 10kgs/m2, but a 4mm thick solid copper panel weighs 35.6kgs/m2. Composite panel can save the weight by 70%. | Composite panel only uses thin copper or brass sheet between 0.3mm to 0.5mm thick, but still keeps all the original decorative effects of solid copper panels. It save the cost by more than 60%. | |
| Fire retardant | Fully recyclable | |
With mineral filled plastic core, the copper composite panel can reach FR B1 grade. | Copper skin sheets and plastic core can be seperated & recycled after its service life. |
