Founded in 2019, DEMTAŞ has quickly established itself as one of Turkey's leading companies in andesite and basalt production, achieving significant success in a short period. Since our establishment, we have embraced quality, trust and customer satisfaction as our core principles.
We offer a fully integrated production process by extracting andesite and basalt stones from our own quarries and processing them in our own manufacturing facilities. This allows us to maintain control over every stage of production, uphold high quality standards and provide reliable solutions to our customers. We operate with the responsibility of being a direct manufacturer, not an intermediary — and we demonstrate this difference in every product.
With a major investment in 2025, we completely renewed our entire production line and machinery, elevating our manufacturing capabilities to the next level. This modernization ensures precision cutting, high accuracy and sustainable quality standards.
We have served as solution partners in Turkey's largest projects with our 24/7 production capacity. Delivering our commitments completely and on time is our top priority. Our sensitivity to timely delivery and logistics has established a business approach that instills confidence in our customers.
Our production facilities and quarries, located in the Gülağaç district of Aksaray province, are situated in the region home to Turkey's highest quality andesite and basalt deposits. This geographical advantage enables us to maintain the highest raw material quality while offering a wide range of products including basalt, andesite, travertine, granite and limra limestone.
Today, we continue to serve with confidence across all 81 provinces of Turkey, backed by our strong references. We process natural stones from our own quarries with our own production power — adding value to the future with trust.
