Production
Production
Three quarries, one 30,000 m² plant and every process in between under our own roof. This is how we keep quality, colour and delivery dates in our hands.
Quarries
Our own stone, from our own mountains
Devtaş operates its own basalt quarry in the Develi district of Kayseri, on the volcanic plateau south of Mount Erciyes, plus a diabase quarry in Tokat and an Ottoman Green quarry. Blocks are graded on site and moved to the plant.
Kayseri basalt
Our own quarry in Develi. Dense, fine-grained black basalt with a declared density of 2,739 kg/m³, our main export product.
Tokat diabase
A very hard, dark green-grey igneous stone from our quarry in Tokat, available as blocks, slabs and cut-to-size on request.
Ottoman Green
A decorative green stone from our Ottoman Green quarry, offered in slabs and tiles on request.

30,000 m² of processing in Develi
Our plant in Develi combines 5,000 m² of covered production halls with 25,000 m² of open block yard and finished-goods storage. A team of 120 and our cutting and finishing lines produce around 1,000 m² of finished stone every day. A 1 MW rooftop solar plant generates our own electricity.

Quality control
Checked at every step
Blocks are graded at the quarry, slabs are inspected after sawing and every packed pallet is checked for dimensions, thickness tolerance, squareness and surface quality. Our ISO 9001 system documents each batch, and CE performance values are declared in the Declaration of Performance.
