HIPOST

Post tensioning is mainly applied to concrete structures but may also be applied to structures made of different materials like steel, wood or others.

It became possible when the industry became able to supply extremely high resistance steel, with tensile stress between 1000 and 2000 MPa. That happened in the first half of the XX century.

Since then the post tensioning has been applied to a countless number of structures like bridges, buildings, tanks, marine structures and many others.

Post tensioning can be applied utilizing high tensile steel bars or wires or strands.

Strands are normally made of 7 wires, 1 of them straight, the other 6 twisted around it and are the most commonly used because they minimize the cost of assembling of the post tensioning tendon made of several strands grouped in the same duct.

HIPOST post tensioning system foresees the use of 15 mm diameter 7 wires strands.
