My company based in New Zealand is looking at designing a guyed tower for
New Zealand conditions and using Dyneema ropes, with are made from
"superstrong" polyethylene fibers. I'm interested in hearing from anyone who
has used this material for guys. Also I'm particularly interested in what is
the practical preload as a % of breaking strength and is the accepted 10% as
used for steel ropes really applicable to materials which are much lighter
than steel and therefore sag will be reduced to an acceptable level with
smaller preloads. At least that's my understanding, but I'm not an expert in
this and would appreciate feedback. Thanks.
