After the corrosion of impregnated hexagonal wire mesh, the original characteristics will be lost, and the shape, color and mechanical properties will be changed, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually, there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment is easier to rust than dry environment, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated six-sided wire mesh, prolong the service life of the product.

There are various specifications of barbed rope, which can be divided into two categories: ordinary barbed rope and blade barbed rope.

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.
