Perforated metal plank Type BN-O33 / O33vi
The perforated metal planks, type BN-O33 “Noppe, offen” combines top and bottom pressed nubs with a hole diameter of 8 mm: This provides excellent stability and drain holes for a good drainage effect.
In combination with the profile BN-O33vi for steps with vi-nosing or the closed profile BN-G33 it results in many applications and variations.

With perforated metal planks, type BN-O33vi “Noppe, offen, vi-nosing” is designed for stair treads and a perfect complement for types BN-O33 and BN-G33. The combination of top and bottom pressed nubs with a hole diameter of 8 mm provides excellent stability and drainage holes for a good drainage effect. Due to the vi-nosing is a tactile and optical recognition function given and the attachment of an additional welded nosing can be omitted.
