Perforated metal plank Type BN-G
The perforated metal planks, type BN-G “Noppe, geschlossen”, the punched nobs pressed upwards are closed and offer high slip resistance. BN-G gratings are often used in indoor environments and there, where, on the one hand, a closed surface is desired and on the other, good accessibility must be ensured.
