Generally, due to wet weather and more precipitation, oxidation and rust of binding iron wire NetEase occurs, so we should better store and use galvanized iron wire to avoid rust as far as possible. About the barbed wire, the surface of the barbed wire attached a layer of galvanized layer, the galvanized layer if too thick will not meet the SGS environmental standards. But if it is too thin, it is easy to oxidize with water molecules and rust.

There are many categories of large coils of galvanized wire, and different categories can be applied to different scenarios. Galvanized iron wire common application is the application of the construction industry, one is the use of binding wire, whether it is the binding of scaffolding or reinforcement, need galvanized iron wire to carry out, the common specifications are 22 and 24 wire, common length of 30cm, 35cm, 40cm, 45cm, 50cm. There is also 20kg or 50kg a bundle of 18, 16, 14, 12, 10 galvanized coil wire.

Good galvanized wire, plating thickness of 3- 4 mm, zinc adhesion should be less than 460 grams/m, that is, the average thickness of zinc layer is not less than 65 microns. When the thickness of plated parts is greater than 4 mm, the zinc adhesion should not be less than 610 g/m, that is, the average thickness of zinc layer should not be less than 86 microns. Standard galvanized wire coating must be uniform, galvanized layer basically uniform with copper sulfate solution test etching five times no dew iron. For standard galvanized wire coating adhesion requirements, the zinc layer of plated parts should be firmly combined with the basic metal and have enough adhesion strength, after hammer test does not fall off, not convex.
