Post tensioning jobs|used in bridge construction as well as other civil engineering structures


Post tensioning jobs is designed and manufactured under quality control program to meet international standards. 

post tensioning jobs  consists of stress-end anchorage, fixed-end (dead-end )anchorage, plastic or metal corrugated duct, coupler and PC strand.

post tensioning jobs mating strands with various diameters: LQM13 for strand diameter 12.5/12.7/12.9mm, LQM15 for strand diameter 15.24/15.3/15.7mm, LQM18 for strand diameter 17.8mm, LQM22 for strand diameter 21.8mm.


1.Adapatable for strand which with various strength such as 1570/1670/1770/1860/2000 MPaand various diameters.

2.Full range of tendon sizes are availabel(1-55 strands and larger sizes are available on request).

3.No need to determine strand length in advance.

4.High anchoring coefficient, reliable and stable.

For LQM post-tensioning system:

Anchor coefficient:  ηa≥0.95

Total strain at ultimate tensile force:   εapu≥2%

5.simple and reliable equipment for installation, tensioning and grouting.

Application: tensioning jobs can be used efficiently in all applications of Building and Civil Engineering works including 

  • Building floor slabs

  • Bridge girders

  • Tanks and Silos

  • many other applications

2. post tensioning jobs is commonly used in bridge construction as well as other civil Engineering structures such as Silo, Water tank etc.

The systems are normally adopted for bonded tendons. The tendons consist of a bundle of strand with a nominal diameter of 0.5" (12.7 mm.) or 0.6" (15.2 mm.).

3. The strands are individually gripped in one anchor head unit and transmits their prestressing force by means of anchor plate casting unit type M.

4. For each anchor size a special spiral reinforcement is provided at the anchor plate casting to give adequate splitting reinforcement for burstling stresses developed at the anchorage zone.

5. The strands in tendon are stressed simultaneously by means of a multi strand stressing jack from capacity 1,100 KN up to 5,000 KN. In case of small size tendon unit such as type M405 the strands can also be stressed individually by means of mono jack. 

6.To ensure corrosion protection and to give adequate bond strength, the tendons are filled with suitable cement grout mix after complete stressing of the strands.
