Ropes and twines

for seaweed cultivation

In collaboration with customers and the Wageningen University We have conducted extensive research into the micro- and macrostructure of various types of rope. These ropes have been subjected to intensive testing, both in laboratory conditions and in practical use at sea. By sowing gametophytes and sporophytes on these ropes, we have observed excellent results: seaweed adheres firmly and grows optimally.

Based on these promising findings, LangmanRopes a special range ropes and twines for seaweed cultivation, developed to meet the unique demands of this rapidly growing industry. Our products are designed for durability and optimal adhesion, suitable for a wide range of conditions – from controlled installations to open water.

Whether you are an experienced seaweed farmer or just starting out: Trust LangmanRopes for reliable solutions that drive growth and productivity.
