Perforated metal plank Type BN-GA

The surface of the perforated metal plank, type BN-GA “Noppen, geschlossen, Ablauflöcher“ is a mix of closed punched nobs facing upwards and conical drain holes facing downwards. This means that the grating does not have any sharp edges on top and can be walked on easily even without footwear. At the same time, however, any liquids can be quickly drained through the conical drain holes so that no hydroplaning can occur.
