BPD 18

Commonly used for large roofs on industrial and agricultural buildings, and also well suited for wall cladding. Borga BPD 18 has a classical look and a very large covering width, which makes it a very economical alternative to traditional 20 mm profiles. The asymmetrical shape with narrow upper ribs and wide bottom grooves gives an ageless appearance to the roof. The profile has a special water groove preventing rainwater to come in through the overlap.

To prevent condensation drops to form in the ceiling of uninsulated buildings, it is recommended to apply Borga DropStop to the undersurface of the roof profiles.

The steel core is passivated and painted with a primer and a top layer in polyester P30, P50 or MAT.
