POLAR has been cooperating with JESSN since 2010 for the manufacturing of trawl doors. Together we have developed 3 series: bottom trawl doors, semi-pelagic trawl doors and pelagic trawl doors. POLAR oversees the design, technology support, and international advertising, while JESSN is tasked with production and marketing. To date, the trawl doors have been exported in large quantities throughout Russia, America, South Africa, Thailand, India, and other countries. Customers have provided positive feedback.
POLAR trawl doors are made using European standard steel. The trawl doors are designed for different sea conditions and operating methods to make sure the doors perform well and have a long lifespan.
