Polarcirkel, the most recognized brand in aquaculture, invented the plastic pen concept in Norway in 1974 and has since supplied more than 45,000 pens worldwide. The pens are made from PE raw materials especially suited for the dynamic loads of the sea, and are available in a wide range of models, shapes and sizes to suit individual needs.
All Polarcirkel pen designs are carried out by our professional TnD department. Independent marine engineering consultants are also involved in advanced static and dynamic load calculations to ensure all designs meet or exceed expected real life loads as well as applicable industry standards.
