As for the protection operation of galvanized barbed rope column, replace the column which is corroded or misinterpreted and so on, and place the replacement area from the beginning, and reinforce the column with unstable pile foundation in time. There is also about the protection of galvanized barbed rope itself, to repair the damaged local, will be severely replaced by rust.

3, PVC plastic coated barbed rope protection function is very good

Hook flower net is made of silk hook, the mesh is uniform, flat net surface, beautiful generous net width, wire diameter is thick, not easy to corrode long life, weaving succinct, beautiful and useful. Widely used for raising chickens, ducks, geese, rabbits and zoo enclosures. Mechanical equipment protection, highway guardrail, sports venues fence, road beautification belt protection network. After the screen is made into a box-like container, it can be used to maintain and support the seawall, hillside, road and bridge, reservoir and other civil engineering.

The difference is that hot dip galvanizing is dipped in zinc solution melted by heating, which has fast production speed and thick but uneven coating. The color is dark, the consumption of zinc metal is much, the formation of infiltration layer with the matrix metal, the corrosion resistance is good, and the outdoor environment of hot dip galvanized can be maintained for decades. Cold galvanized is in the plating tank through the current unidirectional zinc gradually plated on the metal surface, the production speed is slow, uniform coating, thin thickness, usually only 3-15 microns, bright appearance, poor corrosion resistance, generally a few months will rust.

As we all know, even if it is the same kind of steel wire, because of the steel making process, wire drawing process and equipment are not the same, so the quality of steel wire production is not the same. Due to the different mechanical properties of steel wire itself, flattening process and equipment, the width and elongation of steel wire in the flattening process have different effects. Therefore, in the selection of wire diameter, the following three factors should be considered:

With the development of mining industry, pig iron classification in Our country has been very extensive, can satisfy the demand of machinery industry. In general, iron used to produce large coils of galvanized wire can be divided into two classes. A metal produced directly from iron ore and iron smelting, consisting of iron oxide, silicon dioxide, and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed in, so that the refined material is called general pig iron, is also for the initial grade of the material.

Dip plastic six side barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, in particular, is prone to fracture, lose the original protective function.

Barbed rope is to use iron wire, through winding machine, through a variety of weaving technology, wound in the main line (stranded) made of isolation protection net. There are three ways to twist the barbed rope, as detailed below.
