Theboe S.A. (Spanien)
With its pioneering spirit and entrepreneurial flair, Theis-Böger took up contact with the spanish slate industry and was the first german company that imports significant amounts from 1970 onwards. Sold under the name Assulo®, our slate tiles won immediate market acceptance.
In order to meet the quality standards required by our domestic market, our spanish subsidiary Theboe S.A. was founded in 1988. Our own processing plant which uses machinery developed by us that treats the stone with the utmost care and ensures a continuously high quality standard. Permanent material control at the mines forms the basis of this system.
