Perforated metal plank Type BN-G33
The perforated metal planks, type BN-G33 “Noppe, geschlossen” has upwardly pressed closed nubs and provides a high slip resistance. BN-G33 is suitable for indoor in combination with BN-G33vi stairtreads (with i-perforated nosing). BN-G33 is suitable for areas where on the one hand a closed surface is desired and on the other hand a good accessibility must be guaranteed.

With perforated metal planks, type BN-G33vi “Noppe, offen, vi-nosing” is designed for stair treads and a perfect complement for types BN-G33 and BN-O33. The upwardly pressed closed nubs provides a high slip resistance. Due to the vi-nosing is a tactile and optical recognition function given and the attachment of an additional welded nosing can be omitted.
