AmSteel® is a torque-free 12-strand Dyneema® AS-78 single braid that yields the maximum in strength-to-weight ratio and, size for size, is the same strength as steel—yet it floats. AmSteel®-Blue outlasts wire 3:1, making it an excellent wire rope replacement. It has extremely low stretch and superior flex fatigue and wear resistance. Samthane coating enhances that already high abrasion and cut resistance.
