DYWIDAG Bar Post-Tensioning System

The Principle:

DYWIDAG Bars are used for prestressing reinforced concrete elements. The anchor nut absorbs the tensioning force from the post-tensioning bar and rests on the anchor plate, which transfers tensioning force onto the concrete. Thanks to the special design of anchor nut and anchor plate, partial angle compensation is possible to accommodate construction tolerances.

All of the components used for DYWIDAG Bar Post-Tensioning Systems are threadable, thus allowing for quick, easy and safe installation. Thanks to the threadability of the anchor nut, the tension force of the bars can be increased or reduced at any time before grouting.

Characteristics:

• All DYWIDAG Bar Post-Tensioning Systems can be supplied in diameters of 26mm to 47mm
• With regards to steel grades and tensile strengths, high-strength WR/WS tensioning steel is used
• DYWIDAG Bars can be supplied in smooth or threaded tensioning steel
• Quick and reliable supply in accordance with our slogan
  
  “Local Presence-Global Competence“
• Competent staff can be made available on site at any time
• Our systems comply with international specifications and recommendations (Post-Tensioning Institute (PTI), American Association of State Highway and Transportation Officials (AASHTO), British Standard (BS), fédération internationale du béton (fib), European Organisation for Technical Approvals (EOTA), etc.)
• Permanent quality inspections - external as well as internal - insure the safety and reliability of our systems
