DYWIDAG Strand Anchor System - Advantages and Characteristics

DYWIDAG Strand Anchor System

Advantages and Characteristics

  • Large transport lengths avoid splices
  • Need little space during transport, storage and installation
  • 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 of production
