Post Tensioning System

Prestressing force is the compressive stress applied to a structure in advance during construction in order to improve the service performance of the structure.

Prestressing forceis the compressive stress applied to a structure in advance during construction in order to improve the service performance of the structure. Pre-added compressive stress during the service period of the structure can fully or partially offset the tensile stress caused by the load, avoiding the destruction of the structure, and is commonly used in concrete structures.

The Concept of Prestressing Force

A prestressing system usually consists of several components, including anchor, wedge, strand, and bellows.
