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.
  • Excellent fire resistance and low emission of toxic fumes.
  • Wide operating temperature range (from -40 °C to +120 °C).
FIELDS OF APPLICATION
The RAWCELL® Metal - FPA panel is widely used in the most varied fields of application, thanks to its particular characteristics: low weight, high rigidity and flatness, excellent mechanical properties, fire resistance, no toxic fumes and dimensional stability over time. In the civil engineering sector (lift, construction) and in transport, it is used for flooring, subdivision of cabins, ventilated façades. The total recyclability of the panel, being entirely made of metal, makes it usable also wherever regulations or commitment to environmental protection are an essential constraint.
STORAGE
The RAWCELL® Metal - FPA 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.
