The calibrated chains used for winches , with dimensions according to Din 766 and En 818 normes , are actually characterized by a tensile breaking strength that varies from 30 kg/mm^2 for hot dip galva chain up to 50kg/mm^2 for a stainless steel chain. Aqua7 is now presenting a new standard , increasing mechanical performances of calibrated chains up to a tensile breaking strength of 70 kg/mm^2.
With same weight Aqua7 permits to mooring in open and rough water using same winch where a bigger load is needed. Aqua7 is available in hot dip galvanized finishing in drums and marked to distinguish from others grade40 MaggiGroup calibrated chains.
