Unbonded Prestressed Steel Strands are used for cast-in-place concrete and large-load prefabricated beams and other special structures for large-span buildings. It has advange that no need of room for future expasion, no need for grouting, easy construction, saved material, and random bending. Unbonded Prestressed Concrete Steel Strand have been widely used in major domestic engineering projects. Such as: Tianjin Airport, Chongqing Airport, Shijiazhuang Airport, Erdos Stadium and Sichuan, Yunnan, Lhasa and other major construction of hydropower projects.
