Baltimora New modern door collection is different, as its models are made of real wood. The internal structure is blockboard wood: robust, sturdy and durable. The high quality of final products is embellished by their wood grain. In this collection, Bertolotto included very sophisticated models, for highly demanding customers. 58 models and 4 types of wood, with different finishing styles, mat or open-pore lacquering, 16 BP colours and 210 RAL colours to provide endless options.
