Construction units are making use of granite, marble, natural slate and other stones to add more beauty to structures.
In recent years, the Osoksan and Ryonggang granite mines have turned out dressed stone materials, which were used in many construction projects, including Samjiyon City and Ryomyong Street.
Various shapes of granite fence, rail, abrasive stone slab and other stone products preserve their original patterns.
Black stone tile produced by the Kangdong Slate Mine has been introduced into several construction projects, winning high appraisal as an excellent finishing material.
