The technical working group of the industrial metal ceiling manufacturers association (TAIM) defines the standards and quality for the manufacture of metal ceilings, made from galvanized steel. BER metal ceiling panels are manufactured to these standards. One exception, however, is the fire protection ceiling system Metal-V F30 and Metal-V F90, which contain gypsum inserts, which do not neccesarily conform with the distortion tolerance of point 4.2 of the TAIM standard.
