The anticorrosion of these raw materials are very different, the use of life is not the same. Cattle fence cold galvanized, also known as electroplating, galvanized little, rust in rain, but the price is cheap, the use of life in 5-6 years. Hot dip galvanizing (low zinc and high zinc) zinc content in 60 grams to 400 grams, the use of life is about 20-60 years, corrosion resistance is general.

The quality of hot-dip galvanized barbed wire is only good in the surface of the wire attached to the galvanized layer, and with the chemical reaction, the surface of the zinc layer will gradually lose effect because of the oxidation reaction, this situation is more prominent in the humid area of the environment. And because after all, it is rusty iron wire, so the quality of hot-dip galvanized barbed rope is certainly not up to the level of stainless steel barbed rope.

According to the habit often according to the basic galvanized hardware before plating treatment method, as long as it does not contact with water can keep 5~7 years or so without rust, of course, if it is a salt water test, it will not be over 4 hours. Hot dip zinc is to use zinc tin solution to cover the hardware, and the rust prevention time is about five times that of traditional galvanizing. The general outdoor construction is to use hot dip zinc, and the salt water test can do about 36 hours.
