Williams Pre-Stressing / Post Tensioning Systems consist of high tensile steel bars available in five diameters from 1" (26 mm) to 2-1/2" (65 mm) with guaranteed tensile strengths to 778 kips (3460 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.
