Perforated metal plank Type BZ-Gv


The perforated metal plank BZ-Gv “Zahn, groß, verkehrt” offers a free cross section of at least 70%. It is therefore suitable for use in intermediate levels.

Through the use of BZ-Gv profiles, the there is no need for a sprinkler system below these intermediate levels. Optimal flue exhaust and sprinkler suitability are thus guaranteed.
