Protection
Williams Pre-Stressing / Post Tensioning Systems consist of high tensile steel bars available in seven diameters from 1" (26 mm) to 3" (75 mm) with guaranteed tensile strengths to 1027 kips (4568 ­kN). They are provided with cold rolled threads over all or a portion of the bar's length. All tension components for the systems are designed to develop 100% of the bar strength. All components of the systems are designed and manufactured in the United States. Williams All-Thread-Bar systems have been field proven around the world.

Post Tensioning Systems

Applications
Williams All-Thread-Bars were developed for use as Pre-Stressing bars. Over the years many other applications have been adopted such as:

  • Transverse Post Tensioning
  • Longitudinal Post Tensioning
  • Pile Test Anchor
  • Rock Anchors
  • Concrete Ties
  • Hanger Bolts
  • Jacks
  • Structural Steel Frame Ties
  • Shear Pins
  • Bridge Retrofit Applications
  • Pre-Stressed Block and Brick Construction
  • Seismic (earthquake) Restrainer Systems
  • Ground Anchors and Soil Nails
  • Wood Structure Post-Tension Bars
  • Temporary High Strength Connections
  • Tower Base Plate Anchor Bolts
  • Sheet Pile Ties and Tie-backs
  • High Strength Concrete Reinforcement Bars
  • Multiple Corrosion Protection Anchors
  • Wind Generator Foundation Anchor Bolts
