ZJM Post Tensioning System

ZJM Post Tensioning Systems is composed of stressing anchorage (ZJM round anchorage, BM flat anchorage, HM circular anchorage, DM button-head anchorage, YGM precision rolling nut, and LM thread anchorage), dead-end anchorage (dead-end anchorage Type P, dead-end anchorage Type H, dead-end anchorage Type PT), coupler (ZJM.L round coupler, BML flat coupler), duct, tooling anchorage, and stressing equipment. The anchorages can be categorized into different specifications according to the diameter of strands (φ9.5, φ11.1, φ12.7, φ15.2, φ17.8, φ18.9 and φ21.6, etc.) and different prestressing tendons.

Its performance indicators and test parameters can reach the national standard GB/T14370-2015 and JT/T329-2010, as well as FIP-Recommendations for Acceptance and Application of Post-tensioning Systems. The annual manufacturing capacity reaches over 12 million anchor holes and 5000 sets of prestressing equipment.

The advantages of ZJM Post Tensioning Systems:

• Wide applications: It is adaptable for strands with diameters from φ9.5 to φ21.6 and various strengths from 1570MPa to 1960MPa, for high tension wires with diameters from φ4 to φ10 and various strengths from 1570MPa to 1770MPa and other prestressing tendons with different diameter and strength.
