GrandeMat by BILKA


The GrandeMat finish pre-applied on the steel sheet used to manufacture the metal roof tiles provides a higher resistance to the scratches that may appear during the handling and installation operations, but also after the product is installed. Before being introduced, the product was subjected to rigorous testing in laboratories and research facilities in order to confirm the performances of the product and to provide a total warranty of 30 years for colour retention and corrosion resistance.

Manufacturing specifications and uses

The GrandeMat finish for metallic roof tiles is available in 8 colours for the CLASIC, BALCANIC, GOTIC, IBERIC, ROMANIC and RETRO PANEL models. GrandeMat may also be shaped as a corrugated sheet with different sizes of the profile and can be used on roofs and walls, as well.
