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. Bridge / Viaduct beams, Prefabricated Industrial structures, T beams, Concrete pipes and silos, Anchorage and Ground improvement are also used.
