Honeycomb panels

Potmacore is an aluminium eco-friendly and 100% recyclable honeycomb panel. This lightweight, self-supporting and moisture-proof honeycomb panel is ideal for the supporting structures of weight-restricted applications and for module structures.

We constantly develop our products in conjunction with our customers. The structural thicknesses (h) can be adapted to fit the systems of our customers; between 6 to 100mm with a interval of 0,1mm.

Deliveries with different dimensions from one board up to a delivery gross of thousands of boards without minimum delivery quantities.

Potmacore – panel options

The product code numbers are based to the  core cell diameter (d) like shown below.

  • Potmacore 096, d = 9.6mm
  • Potmacore 128, d = 12.8mm
  • Potmacore 192, d = 19.2mm

The stiffness and weights of different board types can be seen in Technical information


Both surfaces coated with epoxy primer which creates an excellent grip for laminating, painting etc.

Epoxy-primer coating is always as standard if nothing else is required.

Potmacore C and C/1

A honeycomb panel with pre-painted surfaces with a temporary protection films. C means that both surface boards are painted, C/1 means that the front surface is painted and the backside is std epoxy-primer.

As a stock color we have RAL9010 (gloss level 30-35), other colours upon request.

Potmacore Lhl ja Lhl/1:

A honeycomb panel with  laminated surfaces. Lhl means that both surfaces are coated with laminated, and Lhl/1 means that the front surface is coated with laminate and the backside is std epoxy-primer.

Also digitally printed laminates available.

Potmacore V ja V/1

A honeycomb panel with  pvc vinyl on surfaces. V means that both surfaces have vinyl on, and V/1 means that the front surface has pvc-vinyl and the backside is std epoxy-primer.

Also digitally printed vinyl surfaces available.

Potmacore C-PU / 1

Honeycomb panel where the other surface has customer specified and  digitally printed aluminium surface.

Image is covered with protective lacquering.

Potmacore PV

All panel alternatives are available also semi-finished, when one surface board is attached to the honeycomb core and the other is delivered along but loose.

This enables the making of curved surfaces. The semi-finished board gets bent to the right curve, thereafter the other surface board will be glued on its position, and a rigid, lightweight and curved structure is formed.

Potmacore B

  1. Bend edge (pos. 1 in picture).Honeycomb panel where the edge is closed by bending the sheet plate. This makes it possible to cover the core also from the sides with the same decor surface as the sheet plate. Plus that it reinforces the edge of the panel and also makes it possible to have fixings to the edges.For panels in thicknesses between 6 – 20( 25)mm.
  2. Edge thinned panel (pos. 2 in picture). Panel edges are pressed thinner (cf. a plasterboard, gyproc), when more space is needed for putty or a joint tape at the junction of boards.
  3. Grooved edge (pos. 3 in picture). Grooving of the edge of the panel makes it possible to use hidden H-profile in the joint of the panels. Also the H-profile is available from Potma.

Edge trimming can be chosen to 1 – 4 edges depending on the customer need.
