Our complete chain range is galvanised as per EN ISO 1461 standard, which requires a minimum 58 micron galvanisation thickness. Our chain goes through regular testing in accelerated seawater environment to guarantee a regular galvanisation quality. A specific engineering process provides a better hold of the galvanisation on the metal, to ensure a longer lifetime. Hot dip galvanisation is engineered with zinc. There may be cases where a marina would be unusually exposed to galvanic currents which could generate a chain deterioration. In such cases, we recommend to use mooring anodes which will protect both the chain and the metallic parts of the boat.Features:- Calibrated chain, suitable for use with a windlass: regular links fit most gipsies.- In plastic drum.Specifications:- Break load: 4030 kg- SWL: Safe Working Load: 1000 kg- Diameter: 8 mm- Length: 30 m- Weight: 42 kg- A: 24- B: 26- EN24565- ISO 4565
