Electric Galvanized Zinc and Spiral PC Strand(DAXIONG)

Product Description

In the absence of any experience can learn from the circumstances， DAXIONG research and develop the prestressed steel strand galvanized electricity production equipment independently, with the domestic and international can only industrialized production electric galvanizing steel wire production line. Because zinc will react with the concrete, galvanized products can only be used for non-concrete used in mining, cable support, plug-ins such as cable-stayed and highway barriers. Compared with traditional hot-dipped galvanized technic，the electric galvanized technic has following advantages： 1）Large difference in coating thickness: Electricity galvanized coating thickness average in *****0g/m2, hot zinc coating thickness is generally about **0g/m2 2) Electricity galvanized have better bonding and surface condition than hot galvanizing, which hard to control its thickness. 3) Electricity galvanized by erosion slower: By Blum, Strauss and Brown in the "Journal" (Volume *6, **5, ***6) report on a series of data shows that the electric galvanized 0.*4 mil / year was significantly lower than that of hot-dipped 0.*7 mil / year. This ratio has been confirmed by experiment.
