GOST 7348-81 Wire for Reinforcement of Prestressed Ferroconcrete Constructions
Wire is produced of die-rolled section and of round shape. The rolled wire grade 75-85 with 0.75-0.85% of carbon is used as a metal block. The wire is made of manufacturing accuracy of groups 1,2,3 according to extreme deviation of diameter. According to extreme deviation of manufacturing status it is produced with tempering. Wire is delivered in bundles of weight not less than 100 kg with internal bundle diameter 1200 mm.
