High quality galvanized wire in general, the zinc layer attached to the surface of the wire is relatively thick, so when we buy galvanized wire, as long as we look at the thickness of the zinc layer machine, we can generally judge whether the quality of galvanized wire is high quality.

There is also in the use of places, blade thorn rope is generally installed and used for the border, walls, prisons and so on, and galvanized thorn rope is in the orchard, fence livestock and so on a large area of installation, although the use of large, but not as high as the use of blade thorn rope and grade, so this is the main reason for the high price. Finally, for the blade barbed wire, the general installation site has high requirements for the protection level, so the quality of the product is also relatively high. But the ordinary galvanized barbed wire has relatively low requirements for the quality in the processing process due to the casual requirements at the installation site.

Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.
