Starting from Tehran's Traditional Stone Market
The journey started in Tehran's central stone market. Practical, on-site learning of real quality became the base for accurate sourcing and trading decisions.
SangeHassan Supply & Production Network
SangeHassan is a natural building-stone supply and production network, from quarry raw blocks and rough stone to slabs, tiles, and finished products. Our focus is reliable B2B collaboration and international export with transparent workflow and quality control.

A Note From Our Founder
Entering Raw Stone and Block Operations
By moving into raw-stone dealership, toll cutting, and factory cutting supervision, the full path from sourcing to deliverable product became operational and controlled.
Natanz Factory and Standardization
Launching the Natanz factory enabled stronger process control, stable quality, output standardization, and more accurate response to multi-stage orders.
Operating Hassan Travertine Quarry
Operating the Hassan travertine quarry completed a key loop in the chain: better input quality control, steadier supply, and more predictable delivery planning.
Services
With a unified process, each stage from stone sourcing to final delivery is systematically defined and documented: quarry supply, quality control, production, finishing, packing, shipping, and order tracking.
