To produce high quality products that meets or exceeds customerâ&#x20AC;&#x2122;s needs,

A Mooring Chain has to endure at least 25 years in tides, winds and the corrosive & harsh offshore environment. For this reason, the fatigue life of a chain is the utmost importance. We installed 6300kN Fatigue Tester to test fullscale chain and accessories for each grade (R5, R4S, R4, R3S & R3) at air and salt water conditions, and also make efforts to develop long-term Fatigue Life Chain.

DaiHan Anchor Chain Mfg. Co., Ltd. invests & supports constantly in R & D. Continuous investmentin R & D is the first step toward customersatisfaction.
