The decision to create a manufacture group about processing and production of building stones with a different belief and the slogan "One step forward"was taken in "August 2016?", which was later called "Ati Sang". The existence of Bagherabad mine (Bayat) as the largest gray mine and the holder of the best gray marble in the world called "Silk Imprador" or "Persian Silk", lack of good quality production, lack of proper distribution network, widespread attention of builders and architects, were some of the reasons for Ati Sang establishment.
