LITHOCELL® Natural Stone – PS3

PS3 is a sandwich panel with a cosmetic finish consisting of a split stone slab (< 3 mm). It has an aluminium honeycomb core and galvanized steel sheet skins. It is obtained by gluing a split stone finish slab to a panel without finish such as the RAWCELL® Metal panel (incollaggio eseguito da marmisti esterni, nostri partner, clienti). Main fields of application: construction, furniture, shipbuilding, lifts.

PROPERTIES
  • Very high resistance to bending, shear and tensile stress.
  • Excellent dimensional stability, also in terms of flatness over time.
  • Very good compressive strength (due to aluminium honeycomb).
  • Excellent ratio between mechanical performance (high) and weight (content).
  • Excellent weather resistance.
  • Ideal for outdoor applications due to its excellent resistance to aggressive weather.
  • Ease of machining with manual or CNC equipment suitable for machining steel.
  • Wide operating temperature range.
  • Excellent fire resistance and low emission of toxic fumes.
FIELDS OF APPLICATION
Typical applications for the LITHOCELL® Natural Stone - PS3 panel include building façades, interior design and general design.
STORAGE
The LITHOCELL® Natural Stone - PS3 panel is a product in the “semi-finished products” category and therefore is subject to further processing; we recommend storing the panels horizontally in a closed and dry environment, possibly away from heat sources and to support them along their edges.
