PC Strand is used primarily for prefabricated concrete elements, hollow core slabs, beams, TT-slabs or railway sleepers and in post tensioning constructions such as bridges, or off-shore applications. Prestressed concrete strand is high carbon steel wire that is stranded together and treated to increase strength.
Post-tensioning is a technique for reinforcing concrete. Post-tensioning tendons, which are prestressing steel cables inside plastic duct or sleeves are positioned in the forms before the concrete is placed.
Post-Tensioning Concrete provides a light yet structurally efficient solution for the construction of commercial office buildings, multi-family housing structures and mixed- use facilities. Longer, thinner slabs of post-tensioning concrete require less reinforcing steel to achieve the strength of other construction methods.
Post-tensioned concrete is also used in parking structures. Properly designed post-tensioned parking structures are virtually crack-free and offer aesthetic freedom. Another advantage of post-tensioned of concrete is fire resistance. It is no surprise that owners of hospital, universities, and parking operators choose to use post-tension concrete. Post-Tensioned concrete is used in millions of parking garages across the US each year.
