We started our journey under the leadership of the chairman of the year 1974, Arap Dokumacı. We continued our journey which started with Doku Construction, adding the companies Doku Aluminum and Doku Energy. Knowing the fact that a road without a target never succeeds, we always set a target. We became a family company with the participation of Abdurrahim Dokumacı in 1984. In our process of being one of the leading companies in the sector from a family company, we established Doku Construction in 1993.

While building constructions in certain cities of Turkey which contribute to their cultures, we brought Alkom Aluminum in the sector in the year of 2003. With the demand resulting from the quality of our products, we established another aluminum company, Alkor Aluminum, in order to fill the gap in the construction sector. In the year of 2008, we established Alkor Aluminum Solar Energy Company.
