Since its establishment in 1993, Dongsuh Industry Co., Ltd. has specialized in manufacturing SEALING products for power generation facilities in Korea. In particular, as we manufacture SEALING products, which are mostly used in critical power generation equipment systems, we value quality stability and develop excellent technical skills.

The reliability of quality has been verified by acquiring 'Q', the highest level of safety of qualified suppliers, including ISO 9001 and 14001, and the five leading power companies under the Korea Electric Power Corp. have various quality certificates.
