Propellers made in Keraniganj power vessels of all sizes

Bangladesh is now producing high-quality propellers for a wide range of motorised water vessels, from small boats to large ships. Several factories have been set up in Keraniganj's Charkaliganj to manufacture propellers. The propellers vary in weight from 3 kg to 2 tonnes and are priced between Tk 1,100 and Tk 1,500 per kg.
