Application Summary AI generated
GB/T 5223.3-2005 specifies the dimensions, mechanical properties, and testing methods for steel bars used in prestressed concrete structures. It is applied in the construction and civil engineering industries for the production of high-strength concrete components such as bridge beams, railway sleepers, and precast building elements. The standard ensures the steel bars meet requirements for tensile strength, elongation, and relaxation performance under stress.
