High-Strength Synthetic Ropes
Cortland
Sealinkers supplies Cortland in India, offering high-performance synthetic ropes and slings. Cortland’s flagship Plasma 12×12 is, in Cortland’s own description, a 12-strand rope in which each strand is in turn a 12-strand construction. That build is used from 1-5/8 in through 8-1/4 in diameter; below that the product is Plasma 12-Strand, a 12×1 braid. Since a 2023 acquisition, Cortland operates alongside sister company Tufropes (also supplied by Sealinkers) under the Cortland International group. Sealinkers brings this advanced technology to Indian offshore and heavy-lift sectors.
Lighter, Stronger, Safer
Since 1977, Sealinkers has been a trusted name in Mumbai’s industrial supply chain. By distributing Cortland’s Plasma ropes, we provide Indian clients with lighter, stronger alternatives to traditional steel wire. Our expertise ensures safe handling and splicing of these high-performance materials.
