Mooring Chain Size:20mm (07011J) 25mm - 22mm brite dippedBlack chain is not galvanised and is simply used for that underwater use on moorings. It is a longer link than used on anchor winches. Because of its continual immersion galvanised chain would not last longer. G30 Also, black chain is generally 40% stronger than short link galvanised. For example 13mm galvanised short link chain is approximately kN80 (K newton) 80, while black chain is kN80 (K newton) 122c. 6. While often referred to as black chain,
