Perforated metal plank Type BZ-GP

The perforated metal plank type BZ-GP has been developed from our approved planking type BZ-GP.

Because of the homogeneous surface it is easy to negotiate. Furthermore the free cross section of 70 % makes a high light permeability and sprinkler suitability possible. Therefore the profile is particularly suitable for suspended ceilings.

There is no need for sprinkler systems below the suspended ceiling. Due to the high point loads, additional planking during the assembly or later is not necessary. Thus, an ideal smoke funnel, sprinkler suitability and efficiency are guaranteed.
