The main difference between the two is the carbon content. The carbon content of iron is 2.11 percent or greater, while the carbon content of steel is 2.11 percent or less. The iron carbon alloy with carbon content above 2.11% is cast iron (pig iron), which is basically not malleable and cannot be drawn into wire. Secondly, the content of impurities is different. The content of harmful impurities such as sulfur and phosphorus in steel is smaller. Steel wire general color focus, iron wire color light point, white point.

Bridge protection system generally do not need to install special drainage system, the use of hexagonal mesh gabion cage, the filling is selected stones, the stones are not easy to wear, and between the stones and stones will retain some space, so it is very good to meet the drainage requirements.

The external environment has a great influence on the storage of cold drawn wire. Especially during the rainy season, special attention should be paid to the air humidity of workshops and warehouses. It is recommended to use moisture test paper with a value between 8 and 10. If the PH value is high, attention should be paid to the corrosion of the internal cold drawing wire. Cold drawing wire in normal environment storage for two years no problem, cold drawing wire will not be corroded. However, it is necessary to place the coil gently during the handling process to avoid the winding position leading to the cable is not smooth.

Hot dip galvanizing is dipped in zinc liquid melted by heating, with fast production speed and thick but uneven coating. The market allows a low thickness of 45 microns and a high of more than 300 microns. 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. Application range of hot dip galvanizing: because the coating is thicker, hot dip galvanizing has better protective performance than electric galvanizing, so it is an important protective coating for iron and steel parts in harsh working environment. Hot-dip galvanized products are widely used in chemical equipment, petroleum processing, Marine exploration, metal structure, power transmission, shipbuilding and other industries, in the field of agriculture such as sprinkler irrigation, greenhouse and construction industry such as water and gas transmission, wire casing, scaffolding, Bridges, highway guardrail and other aspects, has been widely used.

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.

The more turns thorn rope, at the same time will shorten some use the length, but its tensile strength is improved and barbed wire manufacturer production products general laps for the 3 ring, very few customers to use the product requires 5 laps, this time both in processing fees and use the length is calculated need extra.

The use of steel mesh saves a lot of on-site binding and construction site, can end civilized construction, advance the quality of steel structure engineering. Because the steel mesh is prefabricated in the factory, there is no need for site reprocessing, and there is no need for steel chips, because the construction cycle is shortened, and the cost of lifting machinery is reduced.
