  • 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.

  • A remarkable characteristic of stainless steel wire rope is its inherent corrosion resistance to concentrated nitric acid and dilute nitric acid, which makes it easy to be distinguished from most other metals or alloys. But high carbon 420 and 440 steel in the nitric acid point test is slightly corroded, non-ferrous metal encountered concentrated nitric acid is immediately corroded, and dilute nitric acid has strong corrosion on carbon steel.

  • There are generally PVC plastic coating on the cattle net is in the original galvanized steel wire on the cover of a layer of dark green or gray plastic mold, to avoid the corrosion of wire diameter, is conducive to the progress of the anti-rust function of wire diameter. So the better the raw material, the higher the price. Zinc aluminum alloy cattle net is the best metal net on the market, the price is higher than hot dip galvanized raw materials. The service life is about 80-90 years, with excellent anti-corrosion function.
