Post-tensioning multistrand anchorage

QR multistrand anchorage can stress from 1~55pcs strands(12.7mm to 15.2mm type),used widely in all kinds of construction project

 Hefei Qiang Rong Machinery Co., Ltd developed a new anchorage designed to satisfy the increasing expectations of the construction industry . QR multi-strands anchorage is an evolution optimizing new requirements with well proven materials while maximizing cost effectiveness.

QR multi-strands system anchorage can be used as both stressing end and dead end, it can be used for couplers and external cables as well.

According to FIB standard, QR system anchorage can pass fatigue test of 2 million recycles under stress rage 120Mpa and maximal stress up to 0.65fpk.

 

Max stressing force designed valid for concrete strength reaches 20Mpa(cylinder),25Mpa(cube).
