PROPERTIES

  • Excellent resistance to shear and bending forces.

  • Excellent dimensional stability, also in terms of flatness over time.

  • Very good compressive strength (due to aluminium honeycomb).

  • High mechanical performance, compared to the remarkable lightness of the panel.

  • Excellent weather resistance.

  • Wide operating temperature range.

  • Ease of machining with manual or CNC equipment.
FIELDS OF APPLICATION

Typical applications of the RAWCELL  FIBER – PGA 550 panel are in the marble, stone and ceramic markets; the panel is often used for civil engineering applications both indoors and outdoors (including application in ventilated façades); it is supplied in standard or custom sizes to suit all needs.
STORAGE

The RAWCELL  FIBER – PGA 550 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.
