  • The anticorrosion of these raw materials are very different, the use of life is not the same. Cattle fence cold galvanized, also known as electroplating, galvanized little, rust in rain, but the price is cheap, the use of life in 5-6 years. Hot dip galvanizing (low zinc and high zinc) zinc content in 60 grams to 400 grams, the use of life is about 20-60 years, corrosion resistance is general.

  • Hot dip galvanizing is in the hot melt zinc liquid dip plating, production speed, thick but uneven coating, the market allows the thickness of 45 microns, up to 300 microns above. It is dark in color, consumes more zinc metal, forms infiltration layer with base metal, and has good corrosion resistance. Hot dip galvanizing can be maintained for decades in outdoor environment. The protection of zinc coating on iron matrix has two principles: on the one hand, although zinc is more active and easy to oxidize than iron, but its oxide film is not as loose and compact as iron oxide. The dense oxide layer formed on the surface inhibits the further oxidation of zinc in the interior.
