Before pouring the concrete of the component, the prestressed steel bars are first tensioned and anchored on the pedestal, and then the concrete is poured.
After the concrete reaches the specified strength value, the anchorage is released, the steel bars are relaxed, and the prestressing is applied to the concrete, which is called pre tensioning prestressing.
The pre tensioning method has a simple production process, few steps, high efficiency, and easy quality assurance.
