Advantages and Characteristics
– Large transport lengths avoid
splices
– Need little space during transport, storage and installation
Temporary Anchor
– Sturdiness against damage
ensured through flexibility
– Flexibility in lengths made
possible through shortening
of anchors
– Double corrosion protection
can be supplied for permanent
anchors
– Permanent testability of the
corrosion protection possible
through electric isolation
– Easy installation due to
relatively low weight
– Practically no limitation of the
working load due to an optional
number of strands
– Consistent good quality due to
internal and external supervision
