Welcome to the DINAS PLC

Dinas JSC was established in 1973. Since then we have been exploiting and quarrying quartzite in our deposit near the village of Strupetz – 25 km to the west from the city of Sliven. The silica raw material is unique for the country with its chemical and physicomechanical properties. The quartzite is characterized by high silica content, low impurities level and high refractory index.

  The quality of our silica raw material makes it possible for our products of crushed silica sands and aggregates to be used in various applications such as: foundry, construction, mineral filler, gardening etc.
