GTM Composite Double Braid
Dyneema® SK75 Core, HMPE Jacket, Double BraidGTM Composite Double Braid ropes have very high strength, are firm with a round profile, and have extremely low stretch. These durable, torque-free synthetic ropes are excellent for replacing steel wire rope in winch applications and are designed to withstand drum compression. GTM ropes can be used in multiple applications such as vessel mooring lines for Articulated Tug & Barges (ATB’s), Gilson winch lines used in commercial fishing, as well as helicopter long lines. GTM Mooring Lines 24mm to 44mm can be supplied with MEG4 certification.
GTM Double Braid ropes are constructed with a braided Plasma® HMPE fiber core. This core is encased in a tightly braided jacket of a new generation HMPE fiber that offers the highest abrasion and cut resistance durability.* The final construction of core and cover work in balance to provide excellent service life.
GTM braided rope standard color is orange, but is available with a polyurethane finish in clear or any of five additional colors; black, yellow, red, blue or green.
* GTM Composite ropes can also be designed with materials other than HMPE for jacketing depending on application. Linear density & external fiber properties will change depending on jacketing material but the strength will remain the same on a per size basis. Please contact Cortland for further information.
