METALCELL® Laquered – PP

PP is a sandwich panel with a cosmetic finish, made using a panel without finish such as the RAWCELL® Metal FP to which a painted aluminium skin (finish) is applied in place of one of the two structural raw aluminium skins. Main fields of application: construction, furniture, lifts, shipbuilding, railway, road.

PROPERTIES
  • Very high resistance to bending, shear and tensile stress.
  • Excellent dimensional stability, also in terms of flatness over time.
  • Exceptional compressive strength (aluminium honeycomb).
  • Excellent ratio between mechanical performance (high) and weight (content).
  • Excellent weather resistance.
  • Ease of machining with manual or CNC equipment suitable for machining aluminium.
  • Wide operating temperature range.
  • Excellent product recyclability (100%).
FIELDS OF APPLICATION
The METALCELL® Laquered - PP panel is widely used in the most diverse fields of application, thanks to its particular properties: moderate weight, high rigidity and flatness, excellent mechanical properties, fire resistance, no toxic fumes and dimensional stability over time. In the civil engineering field, it is chosen by architectural firms for its versatility both in the structural field (e.g. ventilated façades, floors, partition walls, sunshades, canopies, parapets) and in the finishing field (furnishings and fittings in general). In the transport sector, the railway and naval markets are two fundamental targets for using the panel, which is chosen to build partition walls, false ceilings, bathrooms and floors. The total recyclability of the panel, entirely made of aluminium, extends its use wherever regulations or commitment to environmental protection are an essential constraint.
STORAGE
The METALCELL® Laquered - PP 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.
