Post-tensioning bar(PT Bar) is a material used to reinforce concrete structures. Usually, it is a round plain steel bar, after applying pre-stress, is anchored in the concrete structure using anchoring devices. Post-tensioning bars are commonly used in bridges, floor slabs, foundations, and other concrete structures to increase their load-bearing capacity and seismic performance. The Fusteel PT bar is made of stainless steel which have high strength and excellent corrosion resistant properties.
The
stainless steel post-tensioning system is engineered from heat-treated 17-4PH stainless steel,ensuring exceptional strength exceeding 1030MPa.
