Perforated metal planks, type BN-OP, correspond to type BN-O in terms of the punching pattern, but have twice the number of holes. The drain holes have a diameter of 7 mm and thereby increase the drainage performance and light and air permeability.
Please note that these product properties are not a replacement for the manufacturer's literature and it is always recommended that Lichtgitter UK is consulted before specifying.
