Dimensions And Accuracy Of Galvanized Steel Aug 15, 2017

      Galvanized steel, refers to the ordinary carbon construction steel through the galvanized process can effectively prevent corrosion rust and prolong steel service life, including galvanized zinc plating zinc and hot dip galvanized. Commonly used in building facades, such as glass curtain wall, marble curtain wall, aluminum curtain wall to do columns and stress materials, or used in outdoor telecommunications towers, highways and other open-air construction steel known as galvanized steel, including galvanized zinc plating and hot dip galvanized.Galvanized Steel
      Dimensions and accuracy: the diameter of the steel wire in the strand and its allowable deviation shall conform to the present. Strand twist should not be less than 14 times times its diameter, other multiples of the twist should be indicated in the contract, the outermost twist of the steel strand to the right twist. The twist direction of the outermost steel wire should be opposite to that of the adjacent inner layer steel wire, and should be indicated in the contract if the twist direction needs to be changed. Twisted direction of twisted strand twisted steel strand should be left twist (S). No special requirements? The length of the strand shall not be less than 200m, the length deviation is: nominal length, allowable deviation <1000m+3%≥1000m + 1.5%.Galvanized Steel
      Hydrostatic test hydraulic test should be carried out in the clarinet, but also can be replaced by Eddy current testing. Test pressure or eddy current inspection the size of the specimen should conform to GB 3092. The mechanical property of steel is an important index to ensure the final use performance (mechanical properties) of steel, which depends on the chemical composition and heat treatment system. In the steel pipe standard, according to different use requirements, the tensile performance (tensile strength, yield strength or yield point, elongation) and hardness, toughness index, as well as user requirements of high, low temperature performance.Galvanized Steel
     Galvanized steel strand usually refers to the Liso, pull wire, strengthen the core, and so on, can also be used as overhead transmission of the ground, the highway on both sides of the block cable or structural cable. Galvanized steel strands of 5.4, 6.0, 6.6 and 9.0, with a 1X7 structure, are available for use as an overhead cable for postal poles.Galvanized Steel
