Metal materials
Introduction
The metal plant team is recognized in the metal industry by KOLAS and the domestic and international classification companies(ABS, DVL, Lloyd, NK, KR). Our team is issuing official test certificate for the purpose of export support for heavy industry related companies such as shipbuilding and petrochemical plant which are the main export industries in Korea. We will become a leading testing agency by continuously making efforts to improve R&D and test analysis ability so that we can contribute to technological development and quality improvement of domestic metal parts and materials industry.
