TR 45 A strong roof profile allowing wide distances between purlins. Borga TR 45 is commonly used for roofing industrial and commercial steel halls, combining good covering width with a very high bearing capacity. The profile’s height makes it especially suited for snowy locations or where high rainwater run-off capacity is required. This profile can also be used externally on the walls of larger industrial buildings. The profile has a special water groove preventing rainwater from coming in through the overlap. To prevent condensation drops from forming on 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.
