Who we are
A single source for basalt, from the quarry face to your port
Devtaş was founded in 2007 in Develi, at the foot of Mount Erciyes, the volcano that gave Kayseri its dense black basalt. Today we operate three quarries and a 30,000 m² processing plant, and we ship finished tiles, pavers, kerbs and cladding to seven countries. Because we own every step of the chain, we control quality, colour consistency and delivery dates ourselves.
- Own basalt, diabase and Ottoman Green quarries
- Sawing, polishing, sandblasting, brushing and splitting in-house
- Export packaging and container loading at the factory
Products
