Robline employs STS - Stronger than Steel® cores for high performance applications, e.g., for
cores of backstays and halyards used on race yachts such as TP52. Developed by the experts
at Robline, the special heat stretch process, which includes a defined cooldown phase during
which the rope's structure is defined, makes it possible to achieve an enormous increase in
breaking strength coupled with minimal elongation. Ocean STS should be used wherever
extreme demands need to be met.
