Heavy hexagonal mesh is made of low carbon steel wire galvanized large wire braided, the tensile strength of steel wire is not less than 38kg/m2, the diameter of steel wire can reach 2.0mm-3.2mm, the surface of steel wire is usually hot galvanized protection, galvanized amount can reach 500g/m2.

Especially after passivation of galvanized layer, the surface of the oxide layer is thicker and compact, itself has high oxidation resistance. On the other hand, when the surface of the galvanized layer is damaged, exposing the inner iron matrix, because zinc is more active than iron, zinc will bear the role of sacrificing zinc anode, zinc will be oxidized before iron, so as to protect the iron layer will not be damaged.
