Kolon Engineering & Construction Co., Ltd.
Kolon Engineering & Construction Co., Ltd. is a Private limited company (Ltd.) registered in South Korea under 1208150012, and its current status with Supreme Court Internet Registry (IROS) is active. The company was incorporated on 1 January 1960 and lists its registered address as Gwacheon-si, South Korea. 5 shareholders are on record for Kolon Engineering & Construction Co., Ltd., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.
