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.

Wire mesh depend on own unique strengths are indispensable in building professional, reinforcing crack strengthening anti-cracking material, products with high degree of error is small, uniform mesh, mesh welding, accept ability is strong, not easy deformation, steel wire mesh in different fields have different called, people call it soft steel bar in bridge engineering construction.

High-speed road guardrail net, hexagonal mesh of all kinds of guardrail net, the value of the high-speed road is more prominent, it is not only used in a variety of roads, in a variety of sports ball fields and landslides to take care of, but also to reach a very close utility.

The surface coating of galvanized wire can be seen whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire. 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, we can generally judge the quality of galvanized wire.

Barbed wire can be used to prevent livestock theft, for one thing, because the surface is covered with sharp spikes that make it difficult to get through the barbed wire.
