Prestressing Systems Using Bars
System Description:
Fully Threaded Bar - can be cut and coupled at any point.
Low Relaxation Steel - minimum relaxation during service life.
Prestressing Grade Steel - high strength offers weight savings and reduced working diameters.
Applications:
The post-tension bar system, also referred to as post-tensioning, involves embedding high-strength steel bars within concrete elements, such as slabs and beams, before applying tension. This technique not only reinforces the concrete but also allows for the distribution of loads, thereby reducing potential cracks and increasing the overall structural integrity of the building.
