Application Summary AI generated

This standard specifies the dimensions, mechanical properties, and testing methods for high-strength threaded steel bars used in prestressed concrete structures. It is applied in civil engineering projects such as bridges, high-rise buildings, and large-span roofs where post-tensioning or pre-tensioning systems require reliable anchorage and load-bearing capacity. The standard ensures consistent quality for bars used in tensioning applications to prevent structural failure under stress.
