This paper briefly describes the engineering practice and developing prospect of cold-rolled ribbed steel wires and welded steel fabric in China. Grade 550 cold-rolled ribbed steel wire may be used as main bearing reinforcement, auxiliary reinforcement, stirrups, detailing requirements reinforcement and welded steelfabric in the members of reinforced concrete structures. Grade 650, grade 800, grade 970 and grade 1 170 cold-rolled ribbed steel wires may be used as main bearing reinforcement in the members of prestressed concrete structures.
Keywords: cold-rolled ribbed steel wire; concrete in situ; prestressed concrete member; welded steel fabric
