Prestressed Concrete Strand

 

While large gaps on structures are economically dealt with Prestressed Concrete Strand, at the same time, large areas can be gained as well with the reduction of concrete cross-section. Also the deformations occurring in the prefabricate systems exposed to dynamic loads can be improved with the drawability feature of the steel.
